一、实验环境

 

操作系统：CentOS7.5 Minimal

IP: 192.168.1.105

 

二、安装docker，拉取mongoDB镜像

 

【Docker】CentOS7.x上docker的安装方式

https://www.jianshu.com/p/d1a07a13a76f

 

# docker pull mongo:4.2

# docker run -it --rm mongo:4.2 cat /etc/issue

# docker run -it --rm mongo:4.2 cat /etc/passwd

# docker run -it --rm mongo:4.2 mongo --version

 

三、创建相关安装目录

 

# mkdir  -p   /opt/mongoconfig

# mkdir  -p  /opt/mongoconfigdb

# mkdir  -p  /opt/mongodata

 

拷贝原始配置文件模板

# docker run -it --rm mongo:4.2 cat /etc/mongod.conf.orig > /opt/mongoconfig/mongod.conf

#  cat  /opt/mongoconfig/mongod.conf

 

三、初始化mongDB容器

 

#  docker run -it -d \

  --name mongodb \

  -p 27017:27017  \

  -v /opt/mongoconfigdb:/data/configdb \

  -v /opt/mongodata:/data/db \

  mongo:4.2 mongod 

 

 

登录mongDB，创建管理员账号

#  docker exec -it mongodb mongo

# db.createUser({ user: 'admin', pwd: 'Admin@123', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] });

 

修改配置文件，增加身份认证

 

# grep -Ev "^$|^#" /opt/mongoconfig/mongod.conf

###########################################

storage:

  dbPath: /data/db

  journal:

    enabled: true

systemLog:

  destination: file

  logAppend: true

  path: /dev/stdout

net:

  port: 27017

  bindIp: 0.0.0.0

processManagement:

  timeZoneInfo: /usr/share/zoneinfo

security:

  authorization: enabled

###########################################

#  vim  /opt/mongoconfig/mongod.conf

 

重启mongoDB

# docker rm -f  mongodb

 

# docker run -it -d \

  --name mongodb \

  -p 27017:27017  \

  -v /opt/mongoconfigdb:/data/configdb \

  -v /opt/mongodata:/data/db \

  -v /opt/mongoconfig/mongod.conf:/etc/mongod.conf \

  mongo:4.2 mongod -f /etc/mongod.conf

#  docker exec -it mongodb mongo -u admin -p "Admin@123" --authenticationDatabase admin

# docker logs  -f mongodb

 

四、将服务注册成系统服务

 

# docker rm -f  mongodb

 

编写unit文件

# vim /etc/systemd/system/mongod.service

############################################################
