千家信息网最后更新 2025年11月14日【Mongodb】往分片复制集添加复制成员1.新的成员机器上安装mongo，启动shard1
  1. [root@ip-10-1-2-183 etc]# more shard1.conf
  2. logpath=/usr/local/mongodb/logs/mongo_shard1.log
  3. logappend=true # need logrotae scripts
  4. fork=true
  5. journal=true
  6. port=27019
  7. #vvvvv = true
  8. #diaglog = 3
  9. dbpath=/usr/local/mongodb/shard1
  10. pidfilepath=/usr/local/mongodb/logs/mongo_shard1.pid
  11. bind_ip=10.1.2.183
  12. replSet=shard1
  13. shardsvr=true

/usr/local/mongodb/bin/mongod -f shard1.conf

2.主节点上加入新的复制集成员

可以看到新的成员已经加入复制集中去了
3.shard2 config 加成员同理（过程略）


4.检查是否加入成功
  1. 登陆mongos端口可以看到
  2. [root@ip-10-1-2-32 etc]# /usr/local/mongodb/bin/mongo 10.1.2.32:30000
  3. MongoDB shell version v3.6.4
  4. connecting to: mongodb://10.1.2.32:30000/test
  5. MongoDB server version: 3.6.4
  6. Server has startup warnings:

4.最后修改下配置文件
  1. 避免重启问题，写入配置文件
  2. [root@ip-10-1-2-32 etc]# more mongos.conf
