docker安装mongodb教程

1. 首先安装好docker，这个不用说
2. 因为docker官方无法访问，这里我分享一个docker镜像网站(https://docker.aityp.com/)
3. 首先拉去mongodb的镜像

[root@hadoop ~]# di

拉取镜像命令为 docker pull swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/mongo:7.0.19

4. 这里介绍一下di命令，这是我自定义的命令，为了快捷高效地操作服务器，也分享给大家，具体操作如下，就是给命令起别名

• [root@hadoop ~]# vim /etc/bashrc

• #my design command
  #docker ps
  alias dps='docker ps'                                                                                
                                                                                                          
  #docker ps -a                                                                                           
  alias dpsa="docker ps -a"                                                                               
                                                                                                          
  #docker images                                                                                          
  alias di="docker images"                                                                                
                                                                                                          
  #restart docker                                                                                         
  alias redocker="systemctl restart docker"                                                               
                                                                                                          
  #start redis                                                                                            
  alias redis="docker start redis"                                                                        
                                                                                                          
  #start mysql                                                                                            
  alias mysql="docker start mysql"                                                                        
                                                                                                          
  #start ollama                                                                                           
  alias ollama="docker start ollama"                                                                      
                                                                                                          
  #start mongodb                                                                                          
  alias mongodb="docker start mongodb"                                                                    
                                                                                                          
  #clear 
  alias c="clear"
  

5. 建容器

docker run -d \
  --name mongodb \
  -p 27017:27017 \
  -v /data/mongo/data:/data/db \
  -e MONGO_INITDB_ROOT_USERNAME=admin \
  -e MONGO_INITDB_ROOT_PASSWORD=123456 \
  mongo:7.0.19

6. 启动容器 [root@hadoop ~]# docker start mongodb

7. 查看dps，注意这里是docker ps，因为我用了别名

[root@hadoop ~]# dps                                                                                    
CONTAINER ID   IMAGE          COMMAND                  CREATED       STATUS                  PORTS      
                                     NAMES                                                              
67b4a300d434   mongo:7.0.19   "docker-entrypoint.s…"   11 days ago   Up Less than a second   0.0.0.0:270
17->27017/tcp, :::27017->27017/tcp   mongodb

8. 这里需要注意的是0.0.0.0:27017->27017/tcp, :::27017->27017/tcp ，0.0.0.0才允许外网IP访问，如果这里显示的是127.0.0.1，那么这个mongodb只允许局域网访问，外网IP是无法访问的
9. 进入容器，docker exec -it mongodb bash修改config ，文件在/etc

[root@hadoop ~]# docker exec -it mongodb bash
root@67b4a300d434:/etc# cat mongod.conf.orig 
# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# Where and how to store data.
storage:
  dbPath: /var/lib/mongodb
#  engine:
#  wiredTiger:

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0


# how the process runs
processManagement:
  timeZoneInfo: /usr/share/zoneinfo

security:

#operationProfiling:

#replication:

#sharding:

## Enterprise-Only Options:

#auditLog:

10. 当然，如果还连接不上mongodb服务，排查如下

• 检查本地环境能否ping通mongodb所在的服务器IP

• 检查mongodb服务器防火墙是否开启，是否允许mongodb的端口27017开放并允许你的IP访问

• 其次检查mongodb的配置文件，这里最好设置为0.0.0.0允许所有IP访问，不然只能局域网访问，踩过坑

  net:
    port: 27017
    bindIp: 0.0.0.0
  

• 其次就是检查认证方式和密码，mongodb的默认认证方式是SCRAM-SHA-1，正确填写用户名的密码，认证数据库Authentication database默认为admin

• 如果是腾讯云服务器＋宝塔面板搭建的话，需要到腾讯云官方控制面板的防火墙开启端口，也要在宝塔面板开启端口，同时也要把配置文件设置为允许所有IP访问。（小经验，我使用这种方式搭建过）
