mongodb副本集ip调整(4.4.22)
环境:
Os:Centos 7
mongodb:4.4.22
调整顺序:从节点-->仲裁节点-->主节点
源ip与新ip对应关系(这里只拿修改从库作为例子)
192.168.107-->192.168.104 从节点
1.关闭从节点
/usr/local/services/mongodb/bin/mongo localhost:29001
myrepl:SECONDARY> use admin
myrepl:SECONDARY> db.auth("test","test123");
myrepl:SECONDARY> db.shutdownServer()
2.修改ip
[root@localhost network-scripts]# more ifcfg-enp0s3
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=enp0s3
UUID=2323beca-b693-4a2a-9fcf-6caa2f095bef
DEVICE=enp0s3
ONBOOT=yes
IPADDR=192.168.1.104
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
重启网络
[root@localhost /]#service network restart
3.修改配置文件
[root@localhost conf]# vi /home/middle/mongodb/conf/mongo.cnf
bind_ip=192.168.1.104,127.0.0.1
4.启动从库
/usr/local/services/mongodb/bin/mongod -f /home/middle/mongodb/conf/mongo.cnf
5.登陆主库执行如下命令
/usr/local/services/mongodb/bin/mongo localhost:29001
myrepl:PRIMARY> use admin
myrepl:PRIMARY> db.auth("test","test123");
这个时候查看集群状态(rs.status())会提示连接不到原来的ip:
"lastHeartbeatMessage" : "Error connecting to 192.168.1.107:29001 :: caused by :: No route to host",
查看当前的配置
myrepl:PRIMARY> rs.conf()
{
"_id" : "myrepl",
"version" : 23821,
"protocolVersion" : NumberLong(1),
"writeConcernMajorityJournalDefault" : true,
"members" : [
{
"_id" : 0,
"host" : "192.168.1.102:29001",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
},
{
"_id" : 3,
"host" : "192.168.1.105:29001",
"arbiterOnly" : true,
"buildIndexes" : true,
"hidden" : false,
"priority" : 0,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
},
{
"_id" : 4,
"host" : "192.168.1.107:29001",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
}
],
"settings" : {
"chainingAllowed" : true,
"heartbeatIntervalMillis" : 2000,
"heartbeatTimeoutSecs" : 10,
"electionTimeoutMillis" : 10000,
"catchUpTimeoutMillis" : -1,
"catchUpTakeoverDelayMillis" : 30000,
"getLastErrorModes" : {
},
"getLastErrorDefaults" : {
"w" : 1,
"wtimeout" : 0
},
"replicaSetId" : ObjectId("64b0a3f881b811c4931d4d4c")
}
}
6.进行修改
注意这里的members[2] 中的数值2是member数组的序号
myrepl:PRIMARY>cfg = rs.conf()
myrepl:PRIMARY>cfg.members[2].host="192.168.1.104:29001"
myrepl:PRIMARY>rs.reconfig(cfg)
7.查看副本集状态
myrepl:PRIMARY> rs.status()

#######################修改仲裁节点ip################################
1.关闭仲裁节点
登录仲裁节点
[root@localhost ~]# /usr/local/services/mongodb/bin/mongo localhost:29001
MongoDB shell version v4.4.22
connecting to: mongodb://localhost:29001/test?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("0509b805-d005-46b0-b74e-bdae0667ca48") }
MongoDB server version: 4.4.22
myrepl:ARBITER> use admin
switched to db admin
myrepl:ARBITER> db.shutdownServer()db.shutdownServer()
server should be down...
2.修改ip
我这里新ip修改为192.168.1.106
3.重启网络
[root@localhost network-scripts]# service network restart
4.修改配置文件
[root@localhost conf]# vi /home/middle/mongodb/conf/mongo.cnf
bind_ip=192.168.1.106,127.0.0.1
5.启动mongodb
/usr/local/services/mongodb/bin/mongod -f /home/middle/mongodb/conf/mongo.cnf
6.进行修改
myrepl:PRIMARY>cfg = rs.conf()
myrepl:PRIMARY>cfg.members[1].host="192.168.1.106:29001"
myrepl:PRIMARY>rs.reconfig(cfg)
#######################修改主节点ip################################
1.关闭主节点
登录主节点
[root@localhost ~]# /usr/local/services/mongodb/bin/mongo localhost:29001
MongoDB shell version v4.4.22
connecting to: mongodb://localhost:29001/test?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("0509b805-d005-46b0-b74e-bdae0667ca48") }
MongoDB server version: 4.4.22
myrepl:PRIMARY> use admin
myrepl:PRIMARY> db.auth("test","test123");
myrepl:PRIMARY> db.shutdownServer()
这个时候会发生主从切换,当前的主库停掉了,从库会成为新的主库
2.修改ip
我这里新ip修改为192.168.1.104
3.重启网络
[root@localhost network-scripts]# service network restart
4.修改配置文件
[root@localhost conf]# vi /home/middle/mongodb/conf/mongo.cnf
bind_ip=192.168.1.104,127.0.0.1
5.启动mongodb
/usr/local/services/mongodb/bin/mongod -f /home/middle/mongodb/conf/mongo.cnf
6.登录新主库进行修改
myrepl:PRIMARY>cfg = rs.conf()
myrepl:PRIMARY>cfg.members[0].host="192.168.1.104:29001"
myrepl:PRIMARY>rs.reconfig(cfg)
