Exadata的OS用戶密码过期

Exadata的OS用戶密码过期

发现Exadata上的OS用戶過期了，虽然知道Exadata上的OEL在用户密码上的要求进行了加强，但是發現OS用戶的密碼的有效期只有90天，這樣的話每90天就要修改一次密碼，太麻煩了，就都改成了不收限制：

查看用戶的密碼有效期：

注：上面的celladmin用戶的Password expirs顯示為never，並不是說該用戶的用戶密碼永不過期，而是因為該用戶的密碼已經過期了Password must be changed

 

修改，99999表示永不過期Never：

chage -M 99999 root

chage -M 99999 celladmin

chage -M 99999 cellmonitor

chage -M 99999 public
