Posted 2022-06-03 gsls200808

准备两台虚拟机，系统centos7

ip分配

host1:192.168.3.53

host2:192.168.3.54

安装docker

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum list docker-ce --showduplicates | sort -r
yum install -y docker-ce-18.09.0 docker-ce-cli-18.09.0
systemctl start docker.service
systemctl enable docker.service
docker version

安装docker-compose

curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose version

host1的docker-compose.yml

 version: '3'
 services:
     mongo_rs1:
         image: mongo:3.4
         container_name: mongo_rs1
         volumes: 
         - ~/commpwr/mongodb/log/:/mongodb
         - ~/commpwr/mongodb/db/:/data/db/
         command:
         - /bin/bash
         - -c 
         - mongod --logpath /mongodb/mongo.log  --logappend --dbpath /data/db/ --master --slave --source 192.168.3.54:27017 --autoresync
         ulimits: 
           nproc: 65535
         hostname: mongo_rs1
         restart: always 
         ports:
           - "27017:27017"

host2的docker-compose.yml

 version: '3'
 services:
     mongo_rs2:
         image: mongo:3.4
         container_name: mongo_rs2
         volumes: 
         - ~/commpwr/mongodb/log/:/mongodb
         - ~/commpwr/mongodb/db/:/data/db/
         command: 
         - /bin/bash
         - -c
         - mongod --logpath /mongodb/mongo.log  --logappend --dbpath /data/db/ --master --slave --source 192.168.3.53:27017 --autoresync
         ulimits: 
           nproc: 65535
         hostname: mongo_rs2
         restart: always 
         ports:
           - "27017:27017"

开启防火墙

firewall-cmd --permanent --add-port=27017/tcp
firewall-cmd --reload

开机后使用navicate新建数据库和集合

 

两台机器均可读写，新建空数据库不会同步，在数据库里新建修改集合都会同步。
