How to run from PHP a bash script under root user (with all permissions) and not nobody user - php default user?
thats my output after sudo visudo:
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

What do you need to run PHP as root? You will need to use visudo and edit the sudoers file. The visudo command is available on all UNIX and Linux systems. It provides a safe of editing the /etc/sudoers file.
Put that at the top of your script, make it executable ( chmod +x myscript. php ), and make a Cron job to execute that script (same way you'd execute a bash script). You can also use php myscript.
To give root privileges to a user while executing a shell script, we can use the sudo bash command with the shebang. This will run the shell script as a root user. Example: #!/usr/bin/sudo bash ....
You can use sudo:
exec("sudo /your/script");
You should allow executing your script without password prompt. Run sudo visudo in console and add the following string to the end:
nobody ALL = NOPASSWD: /your/script
You must set up file mode properly to ensure that no one can modify this script and put dangerous contents into it (in root console):
chown root:root /your/script
chmod 755 /your/script
