Memcached with Newznab Server
This guide will help you install memcached on your new server (assuming you’ve just followed the Ubuntu 14.04.2 guide).
Note
This assumes you know linux in general, and know how to use CLI.
Guide written by Stifler. Find me on synIRC #newznab
Version 0.1 - Initial Release
Version 0.2 - Added memcache install and confiure;
Step 1: Install Memcached
Memcached is in the Ubuntu repository and is up to date.:
sudo apt-get install php5-memcached memcached php5-dev
Easy!!! You now have memcached. Now it should have automagically started and also restarted your Apache2, but in case:
sudo service memcached start
Step 2: Lets get some monitoring
INSTALL
Lets install phpMemcacheAdmin
so we can monitor memcached. It can be found here : http://blog.elijaa.org/
At the time of writing version 1.2.2 was the latest, so in terminal:
cd /tmp
wget http://phpmemcacheadmin.googlecode.com/files/phpMemcachedAdmin-1.2.2-r262.tar.gz
cd /var/www
sudo mkdir phpmemcacheadmin
cd phpmemcacheadmin
sudo tar -zxvf /tmp/phpMemcachedAdmin-1.2.2-r262.tar.gz
Note
replace phpMemcachedAdmin-1.2.2-r262.tar.gz
with whatever the current version is.
Serving the page
Time to get apache2 to serve the new webpage.:
sudo nano /etc/apache2/sites-available/phpmemcacheadmin.conf
Now paste this into the file:
<VirtualHost *:12323>
ServerName phpmemcacheadmin
UseCanonicalName Off
ServerAdmin "webmaster@example.com"
DocumentRoot "/var/www/phpmemcacheadmin"
CustomLog /var/log/phpmemcacheadmin-access_log common
ErrorLog /var/log/phpmemcacheadmin-error_log
</VirtualHost>
Save the file.
Now we need to listen on the port 12323:
sudo nano /etc/apache2/ports.conf
Find the line Listen 80
and add Listen 12323
under it. Then save the file.
Now we have to enable the site:
sudo a2ensite phpmemcacheadmin
Finally, we need to enable the phpmemcacheadmin some write permissions:
cd /var/www/phpmemcacheadmin/
sudo chmod 777 Config
Finally, restart apache so the page is served:
sudo service apache2 restart
Now you should be able to browse to http://yourserver:12323
and see the monitoring page.
Step 3: Memcache extension for PHP
Now we need to install and setup the memcache extension. First we have to install it:
sudo pecl install memcache
That will build the extension and install it in /var/lib/php5
Next we need to enable the extension in php.ini.
Note
There are two php.ini files, edit both of them and make the same changes to both files.
sudo nano /etc/php5/cli/php.ini
and:
sudo nano /etc/php5/apache2/php.ini
Find these are labelled Dynamic Extensions and add the following line:
extension=memcache.so
Save the file. Once you have changed both files, you can now restart apache2.
Note
Stop your screen script(s) first.
sudo service apache2 restart
Now you can restart your screen scripts.
Step 4: Enable Memcached and configuration
Firstly we need to enable newznab to use memcache:
sudo nano /var/www/newznab/www/config.php
Find define('CACHEOPT_METHOD', 'none');
and change it to:
define('CACHEOPT_METHOD', 'memcache');
Save the file and restart apache2:
sudo service apache2 restart
If you need to tweak the settings for memcached, they are located in this file /etc/memcached.conf
Done!!
