Apache Setup

Disable modules

We will disable some modules that we are not using thus freeing up memory and also improving security.

Edit /etc/httpd/conf/httpd.conf and comment out the modules as below.

#LoadModule ldap_module modules/mod_ldap.so
#LoadModule authnz_ldap_module modules/mod_authnz_ldap.so
#LoadModule dav_module modules/mod_dav.so
#LoadModule status_module modules/mod_status.so
#LoadModule dav_fs_module modules/mod_dav_fs.so
#LoadModule proxy_module modules/mod_proxy.so
#LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
#LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
#LoadModule proxy_http_module modules/mod_proxy_http.so
#LoadModule proxy_connect_module modules/mod_proxy_connect.so
#LoadModule cache_module modules/mod_cache.so
#LoadModule disk_cache_module modules/mod_disk_cache.so
#LoadModule file_cache_module modules/mod_file_cache.so
#LoadModule mem_cache_module modules/mod_mem_cache.so

Edit /etc/httpd/conf.d/proxy_ajp.conf and comment out as below

#LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

Listen to one ip for https

Apache has to be configured to listed to one address for port 443 as webmin will be using the same port. Edit /etc/httpd/conf.d/ssl

Listen 192,168.1.6:443

Enable gzip compression

We setup gzip compression via the mod_deflate module to improve web server performance and to cut down on bandwidth usage by compressing responses to the client.

SetOutputFilter DEFLATE
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
SetEnvIfNoCase Request_URI \
\.(?:gif|jpe?g|png)$ no-gzip dont-vary
Header append Vary User-Agent env=!dont-vary

Setup logging for the deflate module

DeflateFilterNote deflate_ratio
LogFormat "%v %h %l %u %t \"%r\" %>s %b mod_deflate: %{deflate_ratio}n pct." vhost_with_deflate_info
CustomLog logs/deflate_access_log vhost_with_deflate_info

Increase PHP max memory

Edit the file /etc/php.ini and set the following

memory_limit = 64M

Enable virtual hosting

NameVirtualHost *:80

Create default virtual host

This needs to be the first virtual host, it will be the default on the server the equivalent of the server with out virtual hosting.

<VirtualHost *:80>
        Servername localhost.localdomain
        Serveradmin root@localhost.localdomain
</Virtualhost>
