CentOS 7/8 & Fedora Apache Server Installation and Configuration Role

A very simple role to install and configure a basic instance of Apache web server on CentOS and Fedora.

The only customization for now is some basic performance tuning for low resource servers.

KeepAlive Off

<IfModule prefork.c>
    StartServers        4
    MinSpareServers     20
    MaxSpareServers     40
    MaxClients          200
    MaxRequestsPerChild 4500
</IfModule>

Requirements

None.

Role Variables

Add and customize the following role variables in one of the following locations:

Recommended:

• host_vars/{{ HOSTNAME }}.yml
• group_vars/{{ GROUPNAME }}.yml

Optional:

• {{ roles_path }}/mariuszczyz.centos_apache/defaults/main.yml

Replace {{ HOSTNAME }} and {{ GROUPNAME }} with appropriate inventory names.

It's recommended to add all required variables to hosts_vars and group_vars. This way they will not get overwritten next time the original role is updated.

START_SERVERS	initial number of threads to spawn on service restart	4
MIN_SPARE_SERVERS	number of threads to keep warm	20

MAX_CLIENTS	maximum number of connections	200
MAX_REQUEST_PER_CHILD	max number of request to handle per thread before killing it	4500
