How to change Apache user and group

By webmaster • 2 years ago • Apache HTTP Server

Apache is usually configured only to have access to its DocumentRoot directory and not run any system commands. Apache is not required to have any other access, so the process typically runs as an unprivileged user and group with no shell in most platforms. Unprivileged user is used for security reasons as even an exploit to a poorly written PHP or Perl script will not escalate and cause much harm to the system.

Default user and group for Apache process usually is not the same in different distribution. Ubuntu, for example, sets the default user and group to www-data, while on CentOS, it's apache.

You can configure your Apache process to run as any user or group, including root, if you're running a development environment or your application has such requirements. You can do it by updating the User and Group directives in Apache's configuration file.

Steps to change Apache user and group:

Open Apache's configuration file using your preferred text editor.
```
$ sudo vi /etc/apache2/apache2.conf Password:
```
Related: Location for Apache User and Group configuration
Find User and Group directives in Apache's configuration file.
Set the value to existing user and group that you want Apache process to run as.
```
User root Group root
```
The following example is to run it as root and is a big security risk as an exploited script will have full access to the system.
Make sure the configured user and group has the correct permission to the folder.
```
$ sudo chown --recursive username:groupname /home/user/website/
```

Restart Apache service.

$ sudo systemctl restart apache2 # Ubuntu, Debian, openSUSE and SLES $ sudo systemctl restart httpd # CentOS and Red Hat
