PHP 调用sudo无效

修改配置

键入命令visudo,打开sudoers文件，编辑该文件注释掉Defaults requiretty一行，
并在root ALL=(ALL) ALL末尾追加apache ALL=(ALL) NOPASSWD: ALL然后重启PHP即可

root    ALL=(ALL)       ALL
apache        ALL=(ALL)       NOPASSWD: ALL

加权限

如有php调用脚本（如：shell），须得给脚本授权，如：chmod 755 restart.sh

visudo

遇到visudo：/etc/sudoers 忙，请稍后重试这种问题，直接把visudo进程kill掉就好了
