mongo副本集搭建
任意一台：>use admin >cfg={ _id:"mongo-repl", members:[ {_id:0,host:'192.168.32.101:27017',priority:2}, {_id:1,host:'192.168.32.102:27017',priority:1}, {_id:2,host:'192.168.32.101:27018',arbiterOnly:true}]}
初始化副本集：rs.initiate(cfg)
需要做主库上操作：use admincfg={ _id:"mongo-repl", members:[ {_id:0,host:'192.168.32.101:27017',priority:2}, {_id:1,host:'192.168.32.102:27017',priority:1}, {_id:2,host:'192.168.32.101:27018',arbiterOnly:true}]}重建副本集：rs.reconfig(cfg)删除一个节点：rs.remove("192.168.32.102:27017")添加一个节点：rs.add(hostportstr)
