一. 概述
关于这个nacos是干什么用的,怎么用,在这里就不多说了,可以直接查看官网的相关资料,这里主要说明的是docker部署启动nacos。当然官网页有资料说明怎么使用docker启动nacos,但是感觉官网的好繁琐。
二. 准备
1> 数据库
由于nacos的配置数据等等都是存放在数据库,nacos本身也是依赖数据库的,所以我们首先要准备数据库。数据库的准备可以查看mysql文件夹资料或者 数据库的主从创建资源。我这里使用的是主从数据库,当然也是可以使用单个数据库的。然后就是创建数据库和表格。
- 创建数据库
CREATE DATABASE dawn_nacos
- 数据库下创建表(也可以去官网查找sql文件)

2> docker下载nacos镜像
docker pull nacos/nacos-server
3> 准备文件目录
在linux下创建这样的目录(这是我自己的):
/home/docker/nacos/standalone
4> 准备standlone-nacos.yml文件
version: '3.1'
services:
nacos:
image: nacos/nacos-server:1.1.3
container_name: nacos-standalone-server
environment:
- PREFER_HOST_MODE=hostname
#模式为单体模式
- MODE=standalone
- SPRING_DATASOURCE_PLATFORM=mysql
# 我的主数据
- MYSQL_MASTER_SERVICE_HOST=192.168.47.150
- MYSQL_MASTER_SERVICE_DB_NAME=dawn_nacos
- MYSQL_MASTER_SERVICE_PORT=3306
# 我的从数据库
- MYSQL_SLAVE_SERVICE_HOST=192.168.47.150
- MYSQL_SLAVE_SERVICE_PORT=3307
- MYSQL_MASTER_SERVICE_USER=root
- MYSQL_MASTER_SERVICE_PASSWORD=wszgr
volumes:
# 日志地址映射
- ./logs/:/home/nacos/logs
# 配置文件,这个需要自己准备,如果开启监控还需要配置里面的一些东西,这里暂时不配置
- ./properties/custom.properties:/home/nacos/init.d/custom.properties
ports:
- "8848:8848"
restart: on-failure
将该文件放在/home/docker/nacos/standalone目录下
5> 准备custom.properties文件(上面数据卷映射)
这个可以去官网查找下载,也可以直接使用我的,我就是从官网下载的:
#spring.security.enabled=false
#management.security=false
#security.basic.enabled=false
#nacos.security.ignore.urls=/**
#management.metrics.export.elastic.host=http://localhost:9200
# metrics for prometheus
#management.endpoints.web.exposure.include=*
# metrics for elastic search
#management.metrics.export.elastic.enabled=false
#management.metrics.export.elastic.host=http://localhost:9200
# metrics for influx
#management.metrics.export.influx.enabled=false
#management.metrics.export.influx.db=springboot
#management.metrics.export.influx.uri=http://localhost:8086
#management.metrics.export.influx.auto-create-db=true
#management.metrics.export.influx.consistency=one
#management.metrics.export.influx.compressed=true
将该文件放在/home/docker/nacos/standalone/properties目录下
三. 启动
进入到/home/docker/nacos/standalone目录下,执行以下命令:
docker-compose -f standalone-nacos.yml up -d
在这里我遇到了2个问题,我来分别简单的说一下:
1> iptables failed
具体如下:
通过对网上资料的了解,是由于breidge模式下的docker创建了一个docker0的虚拟网桥,主要是用于宿主机和容器之间的通信,当容器以bridge方式启动的时候,docker容器就会附加到虚拟网桥上面。而我们对防火墙之类的网络相关文件操作的时候可能导致这个虚拟网桥失效,所以我们只需要重启docker便可:
systemctl restart docker
这样就会重新创建虚拟网桥。
2> NoRouteToHostException: No route to host
这个意思是无法路由到主机异常,而且这个错误出来的时候,通常都伴随着无法连接到数据库,也就导致了nacos启动失败了。导致这个异常的原因是容器无法连接到宿主机的指定端口造成的。解决方案是:
- 关闭宿主机的防火墙
- 在宿主机的防火墙上开发指定的端口(我们这里是3306和3307)
关于这两个问题的详细内容查看笔记的docker问题文件夹下内容或者访问容器无法访问宿主机报出 No route to host
四. 测试
打开网页测试连接 http://192.168.47.150:8848/nacos (这是我的虚拟机,你自己按自己的来)
