1、上传部署安装包

[ecx@evm-cfdoa2v9upsudl9c27i0 mongo-4.0.3-deploy]$ tree

4 directories, 9 files

2.部署config server

注意记得开启security

2.1 修改配置文件 Default-Cluster-Configsvr-4.0.conf

security:
  authorization: enabled
  keyFile: /data/mongo4.0_mirror/mongo-4.0.3-deploy/keyfile

# 配置clusterRole
sharding:
  clusterRole: configsv

2.2 启动mongod进程

[ecx@evm-cfdoa2v9upsudl9c27h0 conf]$ /data/mongo4.0_mirror/mongo-4.0.3-deploy/bin/mongod -f /data/mongo4.0_mirror/mongo-4.0.3-deploy/conf/Default-Cluster-Configsvr-4.0.conf 
2023-02-06T06:42:17.019+0000 I CONTROL  [main] Automatically disabling TLS 1.0, to force-enable TLS 1.0 specify --sslDisabledProtocols 'none'
about to fork child process, waiting until server is ready for connections.
forked process: 32542
child process started successfully, parent exiting

2.3 另外两台机执行相同操作

2.4 初始化副本集

# 连接任意一个mongod进程，使用rs.initiate 进行副本集初始化，使用本地登录
[ecx@evm-cfdoa2v9upsudl9c27i0 tzj]$ /data/mongo4.0_mirror/mongo-4.0.3-deploy/bin/mongo --host /tmp/mongodb-27019.sock
MongoDB shell version v4.0.4
connecting to: mongodb://127.0.0.1:27019/
Implicit session: session { "id" : UUID("64fd777f-1259-464e-8ff0-da27bb26f1ed") }
MongoDB server version: 4.0.3
> 

2.5 服务验证

3.部署shard

shard的部署与config server的部署基本相同，主要是配置文件存在如下差异，这里不再重复阐述。

#sharding:
sharding:
  clusterRole: shardsvr

部署后，连接其中一台机器的进程，进行初始化

4.部署mongos

4.1 配置参数

sharding:
  configDB: set_configserver/ip1:port,ip2:port

4.2 启动mongos进程

4.3 添加shard
