RAC集群修改SCANIP

数据运维 2023-12-19 法医 手机阅读

原因：服务器掉电，重启后集群正常，但是远程连接报错。scanip 正常挂靠在节点 1，但是 1521 端口不通。后续运维确定，该 ip 被其他服务器占用。

解决方式：修改集群scanip

具体操作如下：(修改期间不需要停止crs，asm，db)

1、确认集群正常

2、使用root权限，关闭scan监听，scan服务

[root@orcl1 ~]# cd /u01/app/grid_home/bin/ [root@orcl1 bin]# ./srvctl config scan SCAN name: scan-ip, Network: 1/172.16.8.0/255.255.255.0/eth0 SCAN VIP name: scan1, IP: /scan-ip/172.16.8.105 [root@orcl1 bin]# ./srvctl stop scan_listener [root@orcl1 bin]# ./srvctl stop scan [root@orcl1 bin]# ./srvctl status scan SCAN VIP scan1 is enabled SCAN VIP scan1 is not running [root@orcl1 bin]# ip a 1: lo: 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 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever 2: eth0: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether fa:5c:b8:2d:11:00 brd ff:ff:ff:ff:ff:ff inet 172.16.8.74/24 brd 172.16.8.255 scope global noprefixroute eth0 valid_lft forever preferred_lft forever inet 172.16.8.76/24 brd 172.16.8.255 scope global secondary eth0:2 valid_lft forever preferred_lft forever 3: eth1: mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether fa:c1:0f:4a:af:01 brd ff:ff:ff:ff:ff:ff inet 172.16.10.236/24 brd 172.16.10.255 scope global noprefixroute eth1 valid_lft forever preferred_lft forever inet 169.254.173.156/16 brd 169.254.255.255 scope global eth1:1 valid_lft forever preferred_lft forever
