Apache - httpd.conf - mpm_prefork_module Settings

<IfModule mpm_prefork_module>
    StartServers          2
    MinSpareServers       2
    MaxSpareServers       4
    MaxClients            50
    MaxRequestsPerChild   500
</IfModule>

I found that I saved a bunch of memory just by using less apache processes. Instead of spawing 8 processes by default I'm only going to spawn one and limit the max spares to 4, which means after some load I should only have 4 processes lingering around waiting to serve pages.

MySQL - my.cnf settings

skip-innodb
skip-bdb
skip-ndbcluster

I dropped mysql's memory useage by about 11M (sitting right under 5M right now) just by disabling innodb support. I've also done some very heavy WordPress caching using wp-supercache. this basically caches every page and post so that I'm just serving up static html content instead of processing the entire WordPress stack for every page load.

Subversion Setup

First you need to create a repository somewhere in your file system. Then grant apache permissions on that directory.

svnadmin create /var/svn/repository
sudo chown -R www-data:www-data /var/svn/repository

Controlling Access

Access to the repo via the web will be controlled by an htpasswd file located at /var/svn/svn-auth-file. Use the htpasswd command to create the file.

htpasswd -c /var/svn/svn-auth-file <username>

Execute the script again without the -c argument to add more people to the list.

htpasswd /var/svn/svn-auth-file <username_two>

Apache Setup

I usually setup Apache to use Names VirtualHosts to handle multiple websites. We'll make a new named virtualhost for subversion repository.

<VirtualHost *:80>
ServerName svn.your_domain.com
<location />
DAV svn
SVNPath /var/svn/repository

AuthType Basic
AuthName "Subversion repository"
AuthUserFile /var/svn/svn-auth-file
Require valid-user
</location>
</VirtualHost>
