解决crontab无法运行报错:FAILED to authorize user with PAM

解决crontab无法运行报错:FAILED to authorize user with PAM

今天在CentOS7.4下www用户下执行crontab -e 时出现报错信息,通过查看crontab的日志信息如下,无法使用pam授权用户(身份验证令牌不再有效;需要新的令牌)。

查看crontab日志信息

tail -f /var/log/cron

日志报错信息如下:

查看www用户密码有效期

chage -l www
[root@iz2ze6rdks1akg4xed25ngz /]# chage -l www
Last password change                                    : Jul 24, 2019
Password expires                                        : Oct 22, 2020
Password inactive                                       : never
Account expires                                         : never
Minimum number of days between password change          : 7
Maximum number of days between password change          : 90
Number of days of warning before password expires       : 7

由此可见www用户的密码已过期,原密码有效期是90天,导致crontab命令出现执行报错的问题,调整www密码有效期就可以了,一劳永逸的方法是把www密码有效期改为永久,其中99999代表永久,使用如下命令:

chage -M 99999 www

查看www密码有效期已经改为永久了,现在crontab命令就可以正常使用了。

[root@iz2ze6rdks1akg4xed25ngz /]# chage -l www

Account expires                                         : never
Minimum number of days between password change          : 7
