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：
|
1
2
3
4
5
6
|
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：
|
1
2
3
4
|
{ "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：
