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：
