docker-compose.yamldocker部署mongo副本集

1.服务器地址

服务器IP	域名	节点
192.168.201.4	mongodb-primary	primary
192.168.201.5	mongodb-secondary	secondary
192.168.201.6	mongodb-arbiter	arbiter

2.添加hosts

192.168.201.4 mongodb-primary
192.168.201.5 mongodb-secondary
192.168.201.6 mongodb-arbiter

3.生成keyfile文件

sudo yum install openssl
sudo yum install openssl-devel
sudo openssl rand -base64 741 > mongodb-keyfile

# 修改权限
chmod 600 mongodb-keyfile
chown 999 mongodb-keyfile

4.docker-compose

docker-compose.yaml

5.启动容器

docker-compose up -d mongodb-primary
docker-compose up -d mongodb-secondary
docker-compose up -d mongodb-arbiter

6.连接到副本集上并且安装配置

# 进入mongodb-primary容器
docker exec -it mongodb-primary bash

# 登陆mongod
mongo mongodb://admin:123456@mongodb-primary:27017

# 执行配置文件
rs.initiate( {
   _id : "rs0",
   members: [
      { _id: 0, host: "mongodb-primary:27017" ,priority:2},
      { _id: 1, host: "mongodb-secondary:27017",priority:1 },
      { _id: 2, host: "mongodb-arbiter:27017",arbiterOnly:true}
   ]
})

# 查看mongo节点信息
rs.status()
