使用onsctl ping和onsctl debug确定错误信息,发现是无法取得本地机器的IP

 

[root@rac1 bin]# ./onsctl ping
Failed to get IP for localhost (2)
ons is not running ...
[root@rac1 bin]# ./onsctl debug
Failed to get IP for localhost (2)
[root@rac1 bin]#

 

查看机器的hosts文件,发现配置到本机localhost和条目没有了

 

[root@rac1 bin]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
::1 localhost6.localdomain6 localhost6


192.168.0.82 rac1
192.168.0.83 rac2

10.10.10.2 rac2-priv
192.168.0.84 rac1-vip
192.168.0.211 rac2-vip
[root@rac1 bin]#

添加到本机(127.0.0.1)的条目
[root@rac1 bin]# vi /etc/hosts

# Do not remove the following line, or various programs
# that require network functionality will fail.
::1 localhost6.localdomain6 localhost6
127.0.0.1 localhost.localdomain localhost

在另一个节点也添加相同的条目
