CentOS 6 Redis+PHP суулгаж тохируулах хуудсын эх сурвалжийг харах

<p>Redis is an open-source, networked, in-memory, key-value data store with optional durability. It is written in ANSI C. It’s a “NoSQL” key-value data store. More precisely, it is a data structure server. </p>
<p>To install Redis as daemon on  a CentOS/RHEL/cPanel server, do the following steps</p>
<pre>cd /usr/local/
wget http://download.redis.io/releases/redis-2.8.12.tar.gz
tar -xvzf redis-2.8.12.tar.gz
cd redis-2.8.12
make
cp src/redis-server /usr/local/bin
cp src/redis-cli /usr/local/bin
mkdir -p /etc/redis
mkdir -p /var/redis
cp redis.conf /etc/redis/redis.conf
</pre>
<p>Open <strong>/etc/redis/redis.conf </strong>using vi edirot and set the values as follows.</p>
<pre>daemonize yes
port 6379
bind 127.0.0.1
dir  /var/redis/
logfile  /var/log/redis.log
pidfile  /var/run/redis.pid
</pre>
<p>Now  create the startup script. Create  a new file as <strong>/etc/init.d/redis</strong> and add the following contents to it ( Reference https://gist.github.com/paulrosania/257849 ). And make it executable (<strong> chmod 755 /etc/init.d/redis</strong> ). </p>
<pre>#!/bin/sh
#
# redis - this script starts and stops the redis-server daemon
#
# chkconfig:   - 85 15 
# description:  Redis is a persistent key-value database

<p>Now make sure the daemon will start after server reboot.</p>
<pre>chkconfig --add redis
chkconfig redis on
</pre>
<p>Now we can start redis using command /etc/init.d/redis start</p>
<p>To make sure redis is working, run command “<strong>redis-cli ping</strong>” from commandline. If you get result “PONG”, that shows redis is working.</p>
<p>Now install redis PHP extension, using following command.</p>
<pre>pecl install redis
</pre>
<p>Now open php.ini ( /usr/local/lib/php.ini on cPanel servers ) file  and add the following line to it</p>
<pre>extension=redis.so
</pre>
<p>Now restart Apache to apply the changes to php.ini file. </p>

Redis as a PHP Session Handler

<pre>session.save_handler = redis
session.save_path    = tcp://127.0.0.1:6379</pre>

or directly in your page:


<pre>ini_set('session.save_handler', 'redis');
ini_set('session.save_path',    'tcp://127.0.0.1:6379');
</pre>
