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：[root@dm01cel01 ~]# chage -l rootLast password change : Aug 09, 2012Password expires : Nov 07, 2012Password inactive : neverAccount expires : neverMinimum number of days between password change : 1Maximum number of days between password change : 90Number of days of warning before password expires : 7[root@dm01cel01 ~]# chage -l celladminLast password change : password must be changedPassword expires : neverPassword inactive : neverAccount expires : neverMinimum number of days between password change : 1Maximum number of days between password change : 90Number of days of warning before password expires : 7[root@dm01cel01 ~]# chage -l cellmonitorLast password change : May 10, 2012Password expires : Aug 08, 2012Password inactive : neverAccount expires : neverMinimum number of days between password change : 1Maximum number of days between password change : 90Number of days of warning before password expires : 7[root@dm01cel01 ~]# chage -l publicLast password change : Aug 02, 2012Password expires : Oct 31, 2012Password inactive : neverAccount expires : neverMinimum number of days between password change : 1Maximum number of days between password change : 90Number of days of warning before password expires : 7[root@dm01cel01 ~]# 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 rootchage -M 99999 celladminchage -M 99999 cellmonitorchage -M 99999 public [root@dm01cel01 ~]# chage -l rootLast password change : Aug 09, 2012Password expires : neverPassword inactive : neverAccount expires : neverMinimum number of days between password change : 1Maximum number of days between password change : 99999Number of days of warning before password expires : 7[root@dm01cel01 ~]# chage -l celladminLast password change : password must be changedPassword expires : neverPassword inactive : neverAccount expires : neverMinimum number of days between password change : 1Maximum number of days between password change : 99999Number of days of warning before password expires : 7[root@dm01cel01 ~]# chage -l cellmonitorLast password change : May 10, 2012Password expires : neverPassword inactive : neverAccount expires : neverMinimum number of days between password change : 1Maximum number of days between password change : 99999Number of days of warning before password expires : 7[root@dm01cel01 ~]# chage -l publicLast password change : Aug 02, 2012Password expires : neverPassword inactive : neverAccount expires : neverMinimum number of days between password change : 1Maximum number of days between password change : 99999Number of days of warning before password expires : 7其他節點上的用戶使用同樣操作即可。Linux安装虚拟磁带机AIX修改用户名和密码长度限制相关资讯 Exadata
