Oracle 11gR2 RAC修改VIP

修改节点2的VIP192.168.80.13–>192.168.80.16

步骤如下：

以root用户执行

[root@vastdata2 ~]# cd /u01/app/11.2.0/grid/bin/

[root@vastdata2 bin]# ./srvctl config vip -n vastdata2
VIP exists: /vastdata2-vip/192.168.80.13/192.168.80.0/255.255.255.0/eth0, hosting node vastdata2

查看VIP状态

[root@vastdata2 bin]# ./srvctl status vip -n vastdata2
VIP vastdata2-vip is enabled
VIP vastdata2-vip is running on node: vastdata2

查看监听状态

[root@vastdata2 bin]# ./srvctl status listener -n vastdata2
Listener LISTENER is enabled on node(s): vastdata2
Listener LISTENER is running on node(s): vastdata2

停止监听

[root@vastdata2 bin]# ./srvctl stop listener -n vastdata2

查看停掉监听后的状态

[root@vastdata2 bin]# ./srvctl status listener -n vastdata2
Listener LISTENER is enabled on node(s): vastdata2
Listener LISTENER is not running on node(s): vastdata2

停止VIP

[root@vastdata2 bin]# ./srvctl stop vip -n vastdata2

查看停止VIP后的状态

[root@vastdata2 bin]# ./srvctl status vip -n vastdata2
VIP vastdata2-vip is enabled
VIP vastdata2-vip is not running

修改hosts文件

[root@vastdata2 bin]# vi /etc/hosts

192.168.80.2       vastdata1.us.oracle.com           vastdata1
192.168.80.12      vastdata1-vip.us.oracle.com       vastdata1-vip
10.0.0.2           vastdata1-priv1.us.oracle.com     vastdata1-priv1

192.168.80.3       vastdata2.us.oracle.com           vastdata2
192.168.80.16      vastdata2-vip.us.oracle.com       vastdata2-vip
10.0.0.3           vastdata2-priv1.us.oracle.com     vastdata2-priv1

修改VIP地址–该命令给出了新的VIP地址“192.168.80.16”、网络掩码“255.255.255.0”和VIP使用的网卡“eth0”。

[root@vastdata2 bin]# ./srvctl modify nodeapps -n vastdata2 -A 192.168.80.16/255.255.255.0/eth0

开启监听

[root@vastdata2 bin]# ./srvctl start listener -n vastdata2

查看开启监听后的状态

[root@vastdata2 bin]# ./srvctl status listener -n vastdata2
Listener LISTENER is enabled on node(s): vastdata2
Listener LISTENER is running on node(s): vastdata2

验证

[root@vastdata2 bin]# ./srvctl config vip -n vastdata2
VIP exists: /vastdata2-vip/192.168.80.16/192.168.80.0/255.255.255.0/eth0, hosting node vastdata2

获取当前VIP信息
