ip地址配置 mongodb_[MongoDB] 机器换IP之后的设置

组里用的几台机器换了网段，MongoDB需要做重新配置。

查看Replica Set的状态如下：

rs.status()

{

"startupStatus" : 1,

"ok" : 0,

"errmsg" : "loading local.system.replset config (LOADINGCONFIG)"

}

查看Replica Set的config如下，仍然是之前的IP：

rs.conf()

{

"_id" : "nj-mongo",

"version" : 1,

"members" : [

{

"_id" : 1,

"host" : "192.168.131.15:27017"

},

{

"_id" : 2,

"host" : "192.168.131.16:27017"

},

{

"_id" : 3,

"host" : "192.168.131.13:27017",

"arbiterOnly" : true

}

]

}

重新配置：

config = {

"_id" : "nj-mongo",

"version" : 1,

"members" : [

{"_id" : 1,"host" : "10.64.203.235:27017"},

{"_id" : 2,"host" : "10.64.203.234:27017"},

{"_id" : 3,"host" : "10.64.203.237:27017","arbiterOnly" : true}

]

}

rs.reconfig(config, {force: true})

这时会显示：

{

"msg" : "will try this config momentarily, try running rs.conf() again in a few seconds",

"ok" : 1

}

过一会再查看状态：

rs.status()

{

"set" : "nj-mongo",

"date" : ISODate("2014-05-09T09:26:33Z"),

"myState" : 1,

"members" : [

{

"_id" : 1,

"name" : "10.64.203.235:27017",

"health" : 1,

"state" : 1,

"stateStr" : "PRIMARY",

"uptime" : 4724,

"optime" : Timestamp(1397201109, 4),

"optimeDate" : ISODate("2014-04-11T07:25:09Z"),

"self" : true

},

{

"_id" : 2,

"name" : "10.64.203.234:27017",

"health" : 1,

"state" : 2,

"stateStr" : "SECONDARY",

"uptime" : 543,

"optime" : Timestamp(1397201109, 4),

"optimeDate" : ISODate("2014-04-11T07:25:09Z"),

"lastHeartbeat" : ISODate("2014-05-09T09:26:32Z"),

"lastHeartbeatRecv" : ISODate("2014-05-09T09:26:33Z"),

"pingMs" : 0,

"syncingTo" : "10.64.203.235:27017"

},

{

"_id" : 3,

"name" : "10.64.203.237:27017",

"health" : 1,

"state" : 7,

"stateStr" : "ARBITER",

"uptime" : 543,

"lastHeartbeat" : ISODate("2014-05-09T09:26:32Z"),

"lastHeartbeatRecv" : ISODate("2014-05-09T09:26:33Z"),

"pingMs" : 0

}

],

"ok" : 1

}
