十二、安装listener监听
使用oracle用户，在rac1和rac2上都可以起netca
1.打开网络配置界面，选择“Cluster configuration”集群配置方案，点击“Next”，如果你的是单实例就选择“single node configuration”
2.选中两个节点“Select all nodes”，点击“Next”
3.选择监听配置模式“Listener configuration”，点击“Next”
4.选择“Add”添加一个新的监听，点击“Next”，如果已有监听则后三个选项可选
5.给listener起一个名字，我们使用系统默认名LISTENER，然后点击“Next”
6.选择可使用的协议，这里选择TCP协议，点击“Next”
7.使用默认1521端口，点击“Next”
8.系统问是否还要配置其他监听，选择“No”，点击“Next”
[oracle@rac1 database]$ netca
Oracle Net Services Configuration:
Configuring Listener:LISTENER
Default local naming configuration complete.
rac1...
rac2...
Listener configuration complete.
9.监听配置完毕，可以点击“Next”退出
10.在终端窗口可以看到监听的配置情况，直接点击“Finish”
11.运行命令crs_stat -t ，可以看到刚刚配置好的两个监听进程已经启动
[oracle@rac1 ~]$ crs_stat -t
