Apache is the most commonly used Web server on Linux systems. Web servers are used to serve Web pages requested by client computers. Clients typically request and view Web pages using Web browser applications such as <application>Firefox</application>, <application>Opera</application>, <application>Chromium</application>, or <application>Internet Explorer</application>.

sudo apt install apache2

sudo systemctl restart apache2.service

By default, the server writes the transfer log to the file <filename>/var/log/apache2/access.log</filename>. You can change this on a per-site basis in your virtual host configuration files with the <emphasis>CustomLog</emphasis> directive, or omit it to accept the default, specified in <filename> /etc/apache2/conf-available/other-vhosts-access-log.conf</filename>. You may also specify the file to which errors are logged, via the <emphasis>ErrorLog</emphasis> directive, whose default is <filename>/var/log/apache2/error.log</filename>. These are kept separate from the transfer logs to aid in troubleshooting problems with your Apache2 server. You may also specify the <emphasis>LogLevel</emphasis> (the default value is "warn") and the <emphasis>LogFormat</emphasis> (see <filename> /etc/apache2/apache2.conf</filename> for the default value).

You can install additional Apache2 modules and use them with your Web server. For example, run the following command at a terminal prompt to install the <emphasis>MySQL Authentication</emphasis> module:

78.

sudo apt install libapache2-mod-auth-mysql

86.

The <application>mod_ssl</application> module is available in <application>apache2-common</application> package. Execute the following command at a terminal prompt to enable the <application>mod_ssl</application> module:

99.

sudo find /var/www/html -type f -exec chmod g=rw "{}" \;

100.

These commands recursively set the group permission on all files and directories in /var/www/html to read write and set user id. This has the effect of having the files and directories inherit their group and permission from their parrent. Many admins find this useful for allowing multiple users to edit files in a directory tree.
