-
将计划做为容灾演练的mongo member 从复制集中remove rs.remove("hostname:port")
-
连接到mongod容灾节点,将其由other状态变成primary
cfg = rs.conf()
cfg.members = [{
"_id" : 10,
"host" : "hostname:port",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
}]
rs.reconfig(cfg,{force:true})
rs.conf()
查看admin库system.version，如果存在{_id:"minOpTimeRecovery"}记录，删除该记录。
3. 连接到config容灾节点,将其由other状态变成primary
cfg = rs.conf()
cfg.members = [{
"_id" : 10,
"host" : "hostname:port",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
}]
rs.reconfig(cfg,{force:true})
rs.conf()
4. ##更新分片信息
use config
db.shards.update({_id: "分片名"},{$set: {"host" : "容灾节点hostname:数据节点端口号"}})
5. 更新mongos 配置文件中config 连接节点信息，修改为容灾演练的config节点信息
6. 这时期的mongos 就ok了，至此演练结束done
