如何为RAC增加管理IP地址
*************************** 在两个节点添加方法，需要先增加一个网络 （如果不与原先的公网在一个网段）***************************
在生产实践中，往往需要一个集群的维护IP，这个IP同样需要高可用，如果不与原先公网在一个网段，可以采用今天我们测试的方法为集群增加管理IP，但是这种方式的劣势就是需要分配更多IP地址，而地址得对于任何单位都是稀缺资源，其实也可以在一个网段，我们当时在银行时就采用了在同一个公网网段增加管理IP的方法，如果你需要可以的单独联系我，今天我们测试与原先的公网不在一个网段增加管理IP的方法。
1 增加网络
[root@rac1 grid]# srvctl add network -k 200 -S 3.3.3.0/255.255.255.0/eth2 -w static
[root@rac1 grid]# srvctl config network
Network exists: 1/192.168.56.0/255.255.255.0/eth0, type static
Network exists: 200/3.3.3.0/255.255.255.0/eth2, type static
2 增加VIP，这里VIP就是公网IP（具有欺骗性）
之前要修改两个节点的host文件，解析VIP
[root@rac1 grid]# srvctl add vip -n rac1 -A mgr1_vip/255.255.255.0 -k 200
[root@rac1 grid]# srvctl add vip -n rac2 -A mgr2_vip/255.255.255.0 -k 200
查看VIP配置
[root@rac1 grid]# srvctl config vip -n rac1
VIP exists: /mgr1_vip/3.3.3.5/3.3.3.0/255.255.255.0/eth2, hosting node rac1
VIP exists: /rac1-vip/192.168.56.111/192.168.56.0/255.255.255.0/eth0, hosting node rac1
[root@rac1 grid]# srvctl config vip -n rac2
VIP exists: /mgr2_vip/3.3.3.6/3.3.3.0/255.255.255.0/eth2, hosting node rac2
VIP exists: /rac2-vip/192.168.56.222/192.168.56.0/255.255.255.0/eth0, hosting node rac2
3 启动VIP
[root@rac1 grid]# srvctl start vip -i mgr1_vip
[root@rac1 grid]# srvctl start vip -i mgr2_vip
查看VIP状态
[root@rac1 grid]# srvctl status vip -n rac1
VIP mgr1_vip is enabled
VIP mgr1_vip is running on node: rac1
VIP rac1-vip is enabled
VIP rac1-vip is running on node: rac1
[root@rac1 grid]# srvctl status vip -n rac2
VIP mgr2_vip is enabled
VIP mgr2_vip is running on node: rac2
VIP rac2-vip is enabled
VIP rac2-vip is running on node: rac2
4 通过netca创建监听或srvctl 添加监听
[grid@rac1 ~]$ srvctl add listener -l listener_mgr -p 1523 -k 200 -s
检查监听状态，并启动监听
[grid@rac1 ~]$ srvctl status listener -l listener_mgr
Listener LISTENER_MGR is enabled
Listener LISTENER_MGR is not running
[grid@rac1 ~]$ srvctl start listener -l listener_mgr
[grid@rac1 ~]$ srvctl status listener -l listener_mgr
Listener LISTENER_MGR is enabled
Listener LISTENER_MGR is running on node(s): rac2,rac1
5 lsnrctl检查监听状态，看是有服务注册
[grid@rac1 ~]$ lsnrctl status listener_mgr;

STATUS of the LISTENER

6 修改参数local_listener
SQL> alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.56.111)(PORT=1521))','(ADDRESS=(PROTOCOL=TCP)(HOST=3.3.3.5)(PORT=1523))' sid='prod1';
SQL> alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.56.222)(PORT=1521))','(ADDRESS=(PROTOCOL=TCP)(HOST=3.3.3.6)(PORT=1523))' sid='prod2' ;
7 两个节点看服务是否注册到新网络的监听
节点1：
[grid@rac1 ~]$ lsnrctl status listener_mgr;
