Mongodb的副本集部署
以下文档主要用于在单机上使用Docker-compose部署Mongodb副本集测试使用，
生产环境不建议使用单机部署副本集， 除了浪费机器资源外没有任何意义，但是如果用来练手还是可以的
实现有目标：
Mongodb容器清单:
mongo1: 本机IP地址:37017
mongo2: 本机IP地址:37027
mongo3: 本机IP地址:37037
准备配置文件
- Mongodb的主配置文件
三台机器的配置是一样的、Mongodb的优化大家可以根据自己的需求进行配置

部署流程
- 生成集群认证密钥
cd /opt/deploy/mongodb/
openssl rand -base64 756 > keyFile
chmod 400 keyFile
- 创建对应的文件夹并配置相应的权限
mkdir -pv mongodb-{1,2,3}/{conf,data}
chown 999 mongodb* #需要注意容器内的镜像使用的uid和gid是否为这个
cp keyFile mongodb-1/conf/
cp keyFile mongodb-2/conf/
cp keyFile mongodb-3/conf/
chmod 400 mongodb-{1,2,3}/conf/keyFile- 启动docker-compose
# docker-compose up -d
[+] Running 4/4
⠿ Network mongodb_default Created 0.0s
⠿ Container mongo1 Started 0.8s
⠿ Container mongo2 Started 0.8s
⠿ Container mongo3 Started 0.8s
# docker ps -a 可以查看启动是正常

- 进入mongodb机器并创建相应的集群和添加节点操作
mongo
use admin
db.auth('root','sfMongo2023Db')
rs.initiate({_id:"RS1", members: [{_id:0, host: "192.168.39.86:37017"}]})
rs.add(192.168.39.86:37027)
rs.add(192.168.39.86:37037)
- 测试是正常
rs.status()
