【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
  1. [root@ip-10-1-2-32 etc]# /usr/local/mongodb/bin/mongo 10.1.2.32:27019
  2. shard1:PRIMARY> rs.add({_id: 3, host: "10.1.2.183:27019"})

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

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
  3. logpath=/usr/local/mongodb/logs/mongos.log
  4. logappend=true # need logrotae scripts
  5. fork=true
  6. port=30000
  7. pidfilepath=/usr/local/mongodb/logs/mongos.pid
  8. configdb=conf/10.1.2.32:27000,10.1.2.68:27000,10.1.2.175:27000,10.1.2.183:27000
