无密码的 Sudo 问题

使用 sudo 时遇到问题。作为用户，forge我希望能够sudo service php5-fpm reload无需输入密码即可运行。我尝试了以下所有变体。

forge   ALL=NOPASSWD: /usr/bin/service php5-fpm reload
forge   ALL=NOPASSWD: /usr/bin/service
forge   ALL=(ALL:ALL) NOPASSWD: /usr/bin/service
forge   ALL=(ALL:ALL) NOPASSWD: /usr/bin/service php5-fpm reload

但它一直要求我输入密码。尝试登录和退出。

# tail /var/log/auth.log
Sep 16 09:28:19 apps sudo: pam_unix(sudo:auth): conversation failed
Sep 16 09:28:19 apps sudo: pam_unix(sudo:auth): auth could not identify password for [forge]

这是整个文件。

# Host alias specification

# User alias specification

# Cmnd alias specification
Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig

# User privilege specification
root    ALL=(ALL:ALL) ALL
#forge  ALL=NOPASSWD: /usr/bin/service

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

使用 Ubuntu 14.04.1 LTS

$ which service
/usr/sbin/service

问题：

$ sudo service 
[sudo] password for forge:

这就是有效的方法。

视觉：

# Cmnd alias specification
Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig/, /usr/bin/service, /usr/sbin/service

/etc/sudoers.d/forge：

forge   ALL = (ALL) NOPASSWD:   SERVICES

尝试将文件内容移入forge，visudo但没有成功。

答案1

请尝试以下操作：

/etc/sudoers：

# grep -B1 'Cmnd_Alias SERVICES' /etc/sudoers
## Services
Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig
#

/etc/sudoers.d/forge：

# cat /etc/sudoers.d/forge
forge   ALL = (ALL) NOPASSWD:   SERVICES
#

测试

[forge@localhost ~]$ sudo service
Usage: service < option > | --status-all | [ service_name [ command | --full-restart ] ]
[forge@localhost ~]$

调整正确的如果需要，路径service可能会有所不同，具体取决于您的分布，要找到正确的路径，请运行以下命令：

$ which service
/sbin/service
$

答案2

PATH您为二进制文件提供了错误。which输出显示它是，但您在条目中/usr/sbin/service继续指定。/usr/bin/servicesudoers

尝试

forge   ALL=(ALL)     NOPASSWD: /usr/sbin/service
