kingbaseES V8R6集群运维案例之---修改物理IP和VIP案例(V2.0)

文章目录

案例说明：
在KingbaseES V8R6的集群中，ip地址配置在repmgr.conf和kingbase.auto.conf中，如果需要修改集群的物理ip和vip，需要修改这两个配置文件。ip的修改需要停止集群服务，在修改ip前，对于生产环境要规划好停机窗口，以免影响应用的访问。

操作步骤总结：

1、查看和确定主备库后，关闭集群（cluster和db）服务。

2、修改系统ip及/etc/hosts文件中ip。

3、修改集群配置文件repmgr.conf中的物理ip和vip信息。

4、重启系统网络服务应用新的物理ip。

5、启动主备库数据库服务。

6、注册主库到集群。

7、关闭备库数据库服务，将备库节点重新加入到集群，注册备库到集群。

8、查看集群服务状态（cluster和db）并启动主备库repmgrd服务。

9、重启集群（sys_monitor.sh）服务验证。

集群IP信息：

主：192.168.158.24 新主ip：192.168.158.34

备：192.168.158.25 新备ip：192.168.158.35

网关：192.168.158.2 网关：192.168.158.2

[kingbase@localhost bin]$

二、修改物理机ip

主

关闭集群和数据库

apl 复制代码 
#关闭集群和数据库
[kingbase@localhost bin]$ ./sys_monitor.sh stop

修改主物理ip

apl 复制代码 
#修改ip为192.168.158.34
[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33

启用新ip

apl 复制代码 
[root@localhost ~]# ifdown ens33 && ifup ens33

[root@localhost ~]# ip a 
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    inet 192.168.158.34/24 brd 192.168.158.255 scope global noprefixroute ens33
       valid_lft forever preferred_lft forever
    inet6 fe80::d9f2:f13c:d39c:6eef/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

修改备物理ip

apl 复制代码 
#修改ip为192.168.158.35
[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33

启用新ip

apl 复制代码 
[root@localhost ~]# ifdown ens33 && ifup ens33

[root@localhost ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

       valid_lft forever preferred_lft forever
    inet6 fe80::d9f2:f13c:d39c:6eef/64 scope link tentative noprefixroute dadfailed 
       valid_lft forever preferred_lft forever
    inet6 fe80::1dc4:530f:98e:4ace/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

三、修改repmgr.conf 和kingbase.auto.conf配置文件

主：repmgr.conf文件

apl 复制代码 
#将这个ip改为新物理ip
conninfo='host=192.168.158.34 user=esrep dbname=esrep port=54321 connect_timeout=10 keepalives=1 keepalives_idle=2 keepalives_interval=2 keepalives_count=3 tcp_user_timeout=9000'

备：repmgr.conf文件

apl 复制代码 
#将这个ip改为新物理ip
conninfo='host=192.168.158.35 user=esrep dbname=esrep port=54321 connect_timeout=10 keepalives=1 keepalives_idle=2 keepalives_interval=2 keepalives_count=3 tcp_user_timeout=9000'

​ kingbase.auto.conf文件

apl 复制代码 
#将这个ip指向主库ip
primary_conninfo = 'host=192.168.158.34 user=esrep port=54321 application_name=node2 connect_timeout=10 keepalives=1 keepalives_idle=2 keepalives_interval=2 keepalives_count=3 tcp_user_timeout=9000'

四、启动主备库数据库服务

apl 复制代码 
[kingbase@localhost bin]$ ./sys_ctl -D /home/kingbase/cluster/kingbase/data start 
等待服务器进程启动 ....2025-12-17 18:38:43.873 CST [4322] LOG:  sepapower extension initialized

2025-12-17 18:38:44.161 CST [4322] HINT:  Future log output will appear in directory "../sys_log".
 完成
服务器进程已经启动

现在别起集群，因为数据库元数据表里面的信息跟现在的信息是不一致的，所以先手动起数据库

五、注册主库到集群

1、注册primary到集群

apl 复制代码 
[kingbase@localhost bin]$ ./repmgr primary register -F
[INFO] connecting to primary database...
[INFO] "repmgr" extension is already installed
[NOTICE] primary node record (ID: 1) updated

2、查看集群节点状态

apl 复制代码 
[kingbase@localhost bin]$ ./repmgr cluster show
 ID | Name  | Role    | Status        | Upstream | Location | Priority | Timeline | LSN_Lag | Connection string

[WARNING] following issues were detected
  - unable to connect to node "node2" (ID: 2)
  - node "node2" (ID: 2) is registered as an active standby but is unreachable

[HINT] execute with --verbose option to see connection error messages

六、注册备库到集群

1）关闭数据库服务

apl 复制代码 
[kingbase@localhost bin]$ ./sys_ctl -D /home/kingbase/cluster/kingbase/data stop
等待服务器进程关闭 .... 完成
服务器进程已经关闭

2）将备库节点重新加入到集群

apl 复制代码 
[kingbase@localhost bin]$ ./repmgr node rejoin -h 192.168.158.34 -U esrep -d esrep
[NOTICE] rejoin target is node "node1" (ID: 1)
[INFO] timelines are same, this server is not ahead

[NOTICE] start server finish at 2025-12-17 18:46:35.379881
[NOTICE] NODE REJOIN successful

3）注册standby到集群

apl 复制代码 
[kingbase@localhost bin]$ ./repmgr standby register -h 192.168.158.34 -U esrep -d esrep -F
[INFO] connecting to local node "node2" (ID: 2)
[WARNING] database connection parameters not required when the standby to be registered is running
[DETAIL] repmgr uses the "conninfo" parameter in "repmgr.conf" to connect to the standby
[INFO] connecting to primary database
[INFO] standby registration complete
[NOTICE] standby node "node2" (ID: 2) successfully registered

主库查看集群状态和主备流复制状态

1）查看集群节点状态

apl 复制代码 
[kingbase@localhost bin]$ ./repmgr cluster show
