RabbitMQ集群（单机多实例部署）

---

一、单机多实例部署

单机版安装地址：RabbitMQ3.8.4安装和配置

在单机版基础上 ，也就是一台Linux虚拟机上启动多个RabbitMQ实例，部署集群。

1. 在单个Linux虚拟机上运行多个RabbitMQ实例：

• 多个RabbitMQ使用的 端口 号不能冲突
• 多个RabbitMQ使用的磁盘 存储路径 不能冲突
• 多个RabbitMQ的 配置文 件也不能冲突

说明：

在单个Linux虚拟机上运行多个RabbitMQ实例，涉及到RabbitMQ虚拟 主机的名称 不能重复，每个RabbitMQ使用的 端口 不能重复。

RABBITMQ_NODE_PORT ：用于设置RabbitMQ的服务发现，对外发布的其他端口在这个端口基础上计算得来。(指定5672端口)

1.1 端口介绍

端口号	说明
4369	epmd，RabbitMQ节点和CLI工具使用的对等发现服务
5672、5671	分别为不带TLS和带TLS的AMQP 0-9-1和1.0客户端使用
25672	用于节点间和CLI工具通信（Erlang分发服务器端口），并从动态范围分配（默认情况下限制为单个端口，计算为AMQP端口+ 20000）。一般这些端口不应暴露出去。
35672-35682	由CLI工具（Erlang分发客户端端口）用于与节点进行通信，并从动态范围（计算为服务器分发端口+ 10000通过服务器分发端口+ 10010）分配。
15672	HTTP API客户端，管理UI和Rabbitmqadmin（仅在启用了管理插件的情况下）
61613、61614	不带TLS和带TLS的STOMP客户端（仅在启用STOMP插件的情况下）
1883、8883	如果启用了MQTT插件，则不带TLS和具有TLS的MQTT客户端
15674	STOMP-over-WebSockets客户端（仅在启用了Web STOMP插件的情况下）
15675	MQTT-over-WebSockets客户端（仅在启用Web MQTT插件的情况下）
15692	Prometheus指标（仅在启用Prometheus插件的情况下）

RABBITMQ_NODENAME ：用于设置RabbitMQ节点名称， @ 前缀是用户名， @ 后缀是RabbitMQ所在的Linux主机的 hostname 。

通 常：在同一台服务器上，运行多个rabbitmq实例，只要变更5672端口即可。

1.2 数据存储目录：

	通过修改RABBITMQ_NODENAME属性的值，可以修改数据存储和日志存储目录

1.3 日志数据存储目录：

RabbitMQ使用的环境变量：

查看节点的端口信息：

1.5 启动多个rabbitmq实例，方式二：执行命令指定参数

RABBITMQ_NODE_PORT=5672 RABBITMQ_NODENAME=rabbit2 rabbitmq-server
RABBITMQ_NODE_PORT=5673 RABBITMQ_NODENAME=rabbit3 rabbitmq-server
RABBITMQ_NODE_PORT=5674 RABBITMQ_NODENAME=rabbit4 rabbitmq-server

以上命令的运行主要考虑到环境变量的可见性问题。

2. 启动web控制台的管理插件

	例如：web控制台使用的端口都是15672，多个rabbitmq实例需要进行区分

	rabbitmq-plugins enable rabbitmq_management 

rabbitmq从3.3.0开始禁止使用guest/guest权限通过除localhost外的访问。

如果想使用guest/guest通过远程机器访问，需要在rabbitmq配置文件中设置loopback_users为[]，当然也可以按我之前讲的命令自己创建用户。

2.1 修改配置文件的方式：使用guest/guest通过远程机器访问

默认配置文件的位置：/etc/rabbitmq/rabbitmq.conf

	vim /etc/rabbitmq/rabbitmq.conf

测试：

rabbitmq配置参数建议参考官方源码包中的rabbitmq.conf配置文件

## Related doc guide: https://rabbitmq.com/configure.html. See
## https://rabbitmq.com/documentation.html for documentation ToC.

## Networking
## ====================
##
## Related doc guide: https://rabbitmq.com/networking.html.
##
## By default, RabbitMQ will listen on all interfaces, using
## the standard (reserved) AMQP 0-9-1 and 1.0 port.
##
# listeners.tcp.default = 5672


## To listen on a specific interface, provide an IP address with port.
## For example, to listen only on localhost for both IPv4 and IPv6:
##
# IPv4
# listeners.tcp.local    = 127.0.0.1:5672
# IPv6
# listeners.tcp.local_v6 = ::1:5672

## You can define multiple listeners using listener names
# listeners.tcp.other_port = 5673
# listeners.tcp.other_ip   = 10.10.10.10:5672


## TLS listeners are configured in the same fashion as TCP listeners,
## including the option to control the choice of interface.
##
# listeners.ssl.default = 5671

## It is possible to disable regular TCP (non-TLS) listeners. Clients
## not configured to use TLS and the correct TLS-enabled port won't be able
## to connect to this node.
# listeners.tcp = none

## Number of Erlang processes that will accept connections for the TCP
## and TLS listeners.
##
# num_acceptors.tcp = 10
# num_acceptors.ssl = 10

## Socket writer will force GC every so many bytes transferred.
## Default is 1 GiB (`1000000000`). Set to 'off' to disable.
##
# socket_writer.gc_threshold = 1000000000
#
## To disable:
# socket_writer.gc_threshold = off

## Maximum amount of time allowed for the AMQP 0-9-1 and AMQP 1.0 handshake
## (performed after socket connection and TLS handshake) to complete, in milliseconds.
##
# handshake_timeout = 10000

## Set to 'true' to perform reverse DNS lookups when accepting a
## connection. rabbitmqctl and management UI will then display hostnames
## instead of IP addresses. Default value is `false`.
##
# reverse_dns_lookups = false

##
## Security, Access Control
## ==============
##

## Related doc guide: https://rabbitmq.com/access-control.html.

## The default "guest" user is only permitted to access the server
## via a loopback interface (e.g. localhost).
## {loopback_users, [<<"guest">>]},
##
# loopback_users.guest = true

## Uncomment the following line if you want to allow access to the
## guest user from anywhere on the network.
# loopback_users.guest = false

## TLS configuration.

## Select an authentication/authorisation backend to use.
##
## Alternative backends are provided by plugins, such as rabbitmq-auth-backend-ldap.
##
## NB: These settings require certain plugins to be enabled.
##
## Related doc guides:
##
##  * https://rabbitmq.com/plugins.html
##  * https://rabbitmq.com/access-control.html
##

# auth_backends.1   = rabbit_auth_backend_internal

## uses separate backends for authentication and authorisation,
## see below.
# auth_backends.1.authn = rabbit_auth_backend_ldap
# auth_backends.1.authz = rabbit_auth_backend_internal

## The rabbitmq_auth_backend_ldap plugin allows the broker to
## perform authentication and authorisation by deferring to an
## external LDAP server.
##
## Relevant doc guides:
##
## * https://rabbitmq.com/ldap.html
## * https://rabbitmq.com/access-control.html
##
## uses LDAP for both authentication and authorisation
# auth_backends.1 = rabbit_auth_backend_ldap

## uses HTTP service for both authentication and
## authorisation
# auth_backends.1 = rabbit_auth_backend_http

## uses two backends in a chain: HTTP first, then internal
# auth_backends.1   = rabbit_auth_backend_http
# auth_backends.2   = rabbit_auth_backend_internal

## Authentication
## The built-in mechanisms are 'PLAIN',
## 'AMQPLAIN', and 'EXTERNAL' Additional mechanisms can be added via
## plugins.
##
## Related doc guide: https://rabbitmq.com/authentication.html.
##
# auth_mechanisms.1 = PLAIN
# auth_mechanisms.2 = AMQPLAIN

## The rabbitmq-auth-mechanism-ssl plugin makes it possible to
## authenticate a user based on the client's x509 (TLS) certificate.
## Related doc guide: https://rabbitmq.com/authentication.html.
##
## To use auth-mechanism-ssl, the EXTERNAL mechanism should
## be enabled:
##
# auth_mechanisms.1 = PLAIN
# auth_mechanisms.2 = AMQPLAIN
# auth_mechanisms.3 = EXTERNAL

## To force x509 certificate-based authentication on all clients,
## exclude all other mechanisms (note: this will disable password-based
## authentication even for the management UI!):
##
# auth_mechanisms.1 = EXTERNAL

## This pertains to both the rabbitmq-auth-mechanism-ssl plugin and
## STOMP ssl_cert_login configurations. See the RabbitMQ STOMP plugin
## configuration section later in this file and the README in
## https://github.com/rabbitmq/rabbitmq-auth-mechanism-ssl for further
## details.
##
## To use the TLS cert's CN instead of its DN as the username
##
# ssl_cert_login_from   = common_name

## TLS handshake timeout, in milliseconds.
##
# ssl_handshake_timeout = 5000


## Cluster name
##
# cluster_name = dev3.eng.megacorp.local

## Password hashing implementation. Will only affect newly
## created users. To recalculate hash for an existing user
## it's necessary to update her password.
##
## To use SHA-512, set to rabbit_password_hashing_sha512.
##
# password_hashing_module = rabbit_password_hashing_sha256

## When importing definitions exported from versions earlier
## than 3.6.0, it is possible to go back to MD5 (only do this
## as a temporary measure!) by setting this to rabbit_password_hashing_md5.
##
# password_hashing_module = rabbit_password_hashing_md5

##
## Default User / VHost
## ====================
##

## On first start RabbitMQ will create a vhost and a user. These
## config items control what gets created.
## Relevant doc guide: https://rabbitmq.com/access-control.html
##
# default_vhost = /
# default_user = guest
# default_pass = guest

# default_permissions.configure = .*
# default_permissions.read = .*
# default_permissions.write = .*

## Tags for default user
##
## For more details about tags, see the documentation for the
## Management Plugin at https://rabbitmq.com/management.html.
##
# default_user_tags.administrator = true

## Define other tags like this:
# default_user_tags.management = true
# default_user_tags.custom_tag = true

##
## Additional network and protocol related configuration
## =====================================================
##

## Set the default AMQP 0-9-1 heartbeat interval (in seconds).
## Related doc guides:
##
## * https://rabbitmq.com/heartbeats.html
## * https://rabbitmq.com/networking.html
##
# heartbeat = 60

## Set the max permissible size of an AMQP frame (in bytes).
##
# frame_max = 131072

## Set the max frame size the server will accept before connection
## tuning occurs
##
# initial_frame_max = 4096

## Set the max permissible number of channels per connection.
## 0 means "no limit".
##
# channel_max = 128

## Customising TCP Listener (Socket) Configuration.

##

# tcp_listen_options.backlog = 128
# tcp_listen_options.nodelay = true
# tcp_listen_options.exit_on_close = false
#
# tcp_listen_options.keepalive = true
# tcp_listen_options.send_timeout = 15000
#
# tcp_listen_options.buffer = 196608
# tcp_listen_options.sndbuf = 196608
# tcp_listen_options.recbuf = 196608

##
## Resource Limits & Flow Control
## ==============================
##
## Related doc guide: https://rabbitmq.com/memory.html.

## Memory-based Flow Control threshold.
##
# vm_memory_high_watermark.relative = 0.4

## Alternatively, we can set a limit (in bytes) of RAM used by the node.
##
# vm_memory_high_watermark.absolute = 1073741824

## Or you can set absolute value using memory units (with RabbitMQ 3.6.0+).
## Absolute watermark will be ignored if relative is defined!
##
# vm_memory_high_watermark.absolute = 2GB
##
## Supported unit symbols:
##
## k, kiB: kibibytes (2^10 - 1,024 bytes)
## M, MiB: mebibytes (2^20 - 1,048,576 bytes)
## G, GiB: gibibytes (2^30 - 1,073,741,824 bytes)
## kB: kilobytes (10^3 - 1,000 bytes)
## MB: megabytes (10^6 - 1,000,000 bytes)
## GB: gigabytes (10^9 - 1,000,000,000 bytes)



## Fraction of the high watermark limit at which queues start to
## page message out to disc in order to free up memory.
## For example, when vm_memory_high_watermark is set to 0.4 and this value is set to 0.5,
## paging can begin as early as when 20% of total available RAM is used by the node.
##
## Values greater than 1.0 can be dangerous and should be used carefully.
##
## One alternative to this is to use durable queues and publish messages
## as persistent (delivery mode = 2). With this combination queues will
## move messages to disk much more rapidly.
##
## Another alternative is to configure queues to page all messages (both
## persistent and transient) to disk as quickly
## as possible, see https://rabbitmq.com/lazy-queues.html.
##
# vm_memory_high_watermark_paging_ratio = 0.5

## Selects Erlang VM memory consumption calculation strategy. Can be `allocated`, `rss` or `legacy` (aliased as `erlang`),
## Introduced in 3.6.11. `rss` is the default as of 3.6.12.
## See https://github.com/rabbitmq/rabbitmq-server/issues/1223 and rabbitmq/rabbitmq-common#224 for background.
# vm_memory_calculation_strategy = rss

## Interval (in milliseconds) at which we perform the check of the memory
## levels against the watermarks.
##
# memory_monitor_interval = 2500

## The total memory available can be calculated from the OS resources
## - default option - or provided as a configuration parameter.
# total_memory_available_override_value = 2GB

## Set disk free limit (in bytes). Once free disk space reaches this
## lower bound, a disk alarm will be set - see the documentation
## listed above for more details.
##
## Absolute watermark will be ignored if relative is defined!
# disk_free_limit.absolute = 50000

## Or you can set it using memory units (same as in vm_memory_high_watermark)
## with RabbitMQ 3.6.0+.
# disk_free_limit.absolute = 500KB
# disk_free_limit.absolute = 50mb
# disk_free_limit.absolute = 5GB

## Alternatively, we can set a limit relative to total available RAM.
##
## Values lower than 1.0 can be dangerous and should be used carefully.
# disk_free_limit.relative = 2.0

##
## Clustering
## =====================
##
# cluster_partition_handling = ignore

## pause_if_all_down strategy require additional configuration
# cluster_partition_handling = pause_if_all_down

## Recover strategy. Can be either 'autoheal' or 'ignore'
# cluster_partition_handling.pause_if_all_down.recover = ignore

## Node names to check
# cluster_partition_handling.pause_if_all_down.nodes.1 = rabbit@localhost
# cluster_partition_handling.pause_if_all_down.nodes.2 = hare@localhost

## Mirror sync batch size, in messages. Increasing this will speed
## up syncing but total batch size in bytes must not exceed 2 GiB.
## Available in RabbitMQ 3.6.0 or later.
##
# mirroring_sync_batch_size = 4096

## Make clustering happen *automatically* at startup. Only applied
## to nodes that have just been reset or started for the first time.
##
## Relevant doc guide: https://rabbitmq.com//cluster-formation.html
##

# cluster_formation.peer_discovery_backend     = rabbit_peer_discovery_classic_config
#
# cluster_formation.classic_config.nodes.1 = rabbit1@hostname
# cluster_formation.classic_config.nodes.2 = rabbit2@hostname
# cluster_formation.classic_config.nodes.3 = rabbit3@hostname
# cluster_formation.classic_config.nodes.4 = rabbit4@hostname

## DNS-based peer discovery. This backend will list A records
## of the configured hostname and perform reverse lookups for
## the addresses returned.

# cluster_formation.peer_discovery_backend = rabbit_peer_discovery_dns
# cluster_formation.dns.hostname = discovery.eng.example.local

## This node's type can be configured. If you are not sure
## what node type to use, always use 'disc'.
# cluster_formation.node_type = disc

## Interval (in milliseconds) at which we send keepalive messages
## to other cluster members. Note that this is not the same thing
## as net_ticktime; missed keepalive messages will not cause nodes
## to be considered down.
##
# cluster_keepalive_interval = 10000

##
## Statistics Collection
## =====================
##

## Statistics collection interval (in milliseconds). Increasing
## this will reduce the load on management database.
##
# collect_statistics_interval = 5000

## Fine vs. coarse statistics
#
# This value is no longer meant to be configured directly.
#
# See https://www.rabbitmq.com/management.html#fine-stats.

##
## Ra Settings
## =====================
##
## NB: changing these on a node with existing data directory
##     can lead to DATA LOSS.
##
# raft.segment_max_entries = 65536
# raft.wal_max_size_bytes = 1048576
# raft.wal_max_batch_size = 4096
# raft.snapshot_chunk_size = 1000000

##
## Misc/Advanced Options
## =====================
##
## NB: Change these only if you understand what you are doing!
##

## Timeout used when waiting for Mnesia tables in a cluster to
## become available.
##
# mnesia_table_loading_retry_timeout = 30000

## Retries when waiting for Mnesia tables in the cluster startup. Note that
## this setting is not applied to Mnesia upgrades or node deletions.
##
# mnesia_table_loading_retry_limit = 10

## Size in bytes below which to embed messages in the queue index.
## Related doc guide: https://rabbitmq.com/persistence-conf.html
##
# queue_index_embed_msgs_below = 4096

## You can also set this size in memory units
##
# queue_index_embed_msgs_below = 4kb

## Whether or not to enable background periodic forced GC runs for all
## Erlang processes on the node in "waiting" state.
##
## Disabling background GC may reduce latency for client operations,
## keeping it enabled may reduce median RAM usage by the binary heap
## (see https://www.erlang-solutions.com/blog/erlang-garbage-collector.html).
##
## Before trying this option, please take a look at the memory
## breakdown (https://www.rabbitmq.com/memory-use.html).
##
# background_gc_enabled = false

## Target (desired) interval (in milliseconds) at which we run background GC.
## The actual interval will vary depending on how long it takes to execute
## the operation (can be higher than this interval). Values less than
## 30000 milliseconds are not recommended.
##
# background_gc_target_interval = 60000

## Whether or not to enable proxy protocol support.
## Once enabled, clients cannot directly connect to the broker
## anymore. They must connect through a load balancer that sends the
## proxy protocol header to the broker at connection time.
## This setting applies only to AMQP clients, other protocols
## like MQTT or STOMP have their own setting to enable proxy protocol.
## See the plugins documentation for more information.
##
# proxy_protocol = false

## Overriden product name and version.
## They are set to "RabbitMQ" and the release version by default.
# product.name = RabbitMQ
# product.version = 1.2.3

## "Message of the day" file.
## Its content is used to expand the logged and printed banners.
## Default to /etc/rabbitmq/motd on Unix, %APPDATA%\RabbitMQ\motd.txt
## on Windows.
# motd_file = /etc/rabbitmq/motd

## Related doc guide: https://rabbitmq.com/ldap.html.
##
## ----------------------------------------------------------------------------

# =======================================
# LDAP section
# =======================================

##
## Connecting to the LDAP server(s)
## ================================
##

## Specify servers to bind to. You *must* set this in order for the plugin
## to work properly.
##
# auth_ldap.servers.1 = your-server-name-goes-here

## You can define multiple servers
# auth_ldap.servers.2 = your-other-server

## Connect to the LDAP server using TLS
##
# auth_ldap.use_ssl = false

## Specify the LDAP port to connect to
##
# auth_ldap.port = 389

## LDAP connection timeout, in milliseconds or 'infinity'
##
# auth_ldap.timeout = infinity

## Or number
# auth_ldap.timeout = 500

## Enable logging of LDAP queries.
## One of
##   - false (no logging is performed)
##   - true (verbose logging of the logic used by the plugin)
##   - network (as true, but additionally logs LDAP network traffic)
##
## Defaults to false.
##
# auth_ldap.log = false

## Also can be true or network
# auth_ldap.log = true
# auth_ldap.log = network

##
## Authentication
## ==============
##

## Pattern to convert the username given through AMQP to a DN before
## binding
##
# auth_ldap.user_dn_pattern = cn=${username},ou=People,dc=example,dc=com

## Alternatively, you can convert a username to a Distinguished
## Name via an LDAP lookup after binding. See the documentation for
## full details.

## When converting a username to a dn via a lookup, set these to
## the name of the attribute that represents the user name, and the
## base DN for the lookup query.
##
# auth_ldap.dn_lookup_attribute = userPrincipalName
# auth_ldap.dn_lookup_base      = DC=gopivotal,DC=com

## Controls how to bind for authorisation queries and also to
## retrieve the details of users logging in without presenting a
## password (e.g., SASL EXTERNAL).
## One of
##  - as_user (to bind as the authenticated user - requires a password)
##  - anon    (to bind anonymously)
##  - {UserDN, Password} (to bind with a specified user name and password)
##
## Defaults to 'as_user'.
##
# auth_ldap.other_bind = as_user

## Or can be more complex:
# auth_ldap.other_bind.user_dn  = User
# auth_ldap.other_bind.password = Password

## If user_dn and password defined - other options is ignored.

# -----------------------------
# Too complex section of LDAP
# -----------------------------

##
## Authorisation
## =============
##

## The LDAP plugin can perform a variety of queries against your
## LDAP server to determine questions of authorisation.
##
## Related doc guide: https://rabbitmq.com/ldap.html#authorisation.

## Following configuration should be defined in advanced.config file
## DO NOT UNCOMMENT THESE LINES!

## Set the query to use when determining vhost access
##
## {vhost_access_query, {in_group,
##                       "ou=${vhost}-users,ou=vhosts,dc=example,dc=com"}},

## Set the query to use when determining resource (e.g., queue) access
##
## {resource_access_query, {constant, true}},

## Set queries to determine which tags a user has
##
## {tag_queries, []}
#   ]},
# -----------------------------

2.2 自定义配置文件，不使用默认配置文件

注意：如果要使用自定义位置的配置文件，需要目录属于 rabbitmq 组。

我们在/opt/rabbitconf中创建三个配置文件：

	rabbit1.conf
	rabbit2.conf
	rabbit3.conf
	
	其中注明三个RabbitMQ实例使用的rabbitmq_management插件使用的端口号，以及开通guest远程登录系统的权限：

文件路径	内容
/opt/rabbitmqconf/rabbit1.conf	loopback_users.guest=false management.tcp.port=6001
/opt/rabbitmqconf/rabbit2.conf	loopback_users.guest=false management.tcp.port=6002
/opt/rabbitmqconf/rabbit2.conf	loopback_users.guest=false management.tcp.port=6003

创建配置文件目录和配置文件

修改配置文件，设置插件占用端口

启动rabbitmq实例1，设置端口和文件

启动rabbitmq其他实例，设置端口和文件

2.3 启动命令：

节点名称	命令
rabbit1	RABBITMQ_NODENAME=rabbit1 RABBITMQ_NODE_PORT=5001 RABBITMQ_CONFIG_FILE=/opt/rabbitconf/rabbit1.conf rabbitmq-server
rabbit2	RABBITMQ_NODENAME=rabbit1 RABBITMQ_NODE_PORT=5001 RABBITMQ_CONFIG_FILE=/opt/rabbitconf/rabbit1.conf rabbitmq-server
rabbit3	RABBITMQ_NODENAME=rabbit1 RABBITMQ_NODE_PORT=5001 RABBITMQ_CONFIG_FILE=/opt/rabbitconf/rabbit1.conf rabbitmq-server

2.4 停止命令：

节点名称	命令
rabbit1	rabbitmqctl -n rabbit1 stop
rabbit2	rabbitmqctl -n rabbit2 stop
rabbit3	rabbitmqctl -n rabbit3 stop
