如何在root用户下从PHP运行bash脚本

Question

如何从PHP运行根用户下的bash脚本(具有所有权限)而不是没有用户 - php默认用户？

这是我在sudo visudo之后的输出:

Defaults        env_keep += "LINES COLUMNS"
Defaults        env_keep += "LSCOLORS"
Defaults        env_keep += "SSH_AUTH_SOCK"
Defaults        env_keep += "TZ"
Defaults        env_keep += "DISPLAY XAUTHORIZATION XAUTHORITY"
Defaults        env_keep += "EDITOR VISUAL"
Defaults        env_keep += "HOME MAIL"

#User privilege specification
root    ALL=(ALL) ALL
%admin  ALL=(ALL) ALL


# Uncomment to allow people in group wheel to run all commands
# %wheel        ALL=(ALL) ALL

# Same thing without a password
# %wheel        ALL=(ALL) NOPASSWD: ALL

# Samples
# %users  ALL=/sbin/mount /cdrom,/sbin/umount /cdrom
# %users  localhost=/sbin/shutdown -h now

你可以使用sudo:

exec("sudo /your/script");

您应该允许在没有密码提示的情况下执行脚本 sudo visudo在控制台中运行并将以下字符串添加到结尾:

nobody ALL = NOPASSWD: /your/script

您必须正确设置文件模式,以确保没有人可以修改此脚本并将危险内容放入其中(在根控制台中):

chown root:root /your/script
chmod 755 /your/script
