Linux Redis Configuration and enable PHP support

Redis currently (20150525) has been updated to version 3.0, today we will learn how to deploy Redis on the server and enable PHP support.

I. Redis

Download installation

Each version of Redis can be found in http://download.redis.io/releases/

wget http://download.redis.io/releases/redis-stable.tar.gz
Tar zxf redis-stable.tar.gz
CD redis-stable
Make && make install

# Copy configuration file
CP redis.conf/etc/redis.conf

# Copy binary files to/usr/local/bin
CD src
CP Redis-server REDIS-CLI redis-benchmark/usr/local/bin/
This redis installation is complete.

Configure Redis

After the installation is complete, we need to do some configuration work.

Redis-server-v
#Redis server v=3.0.1 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 BUILD=3858E635DE930C10

# Create a database folder
mkdir/var/lib/redis_db/-P

Vim/etc/redis.conf

# Modify the following variables

Daemonize Yes # daemon Run
LogFile "/var/log/redis.log" # log file
dir/var/lib/redis_db/# Data Persistence folder
Now that the basic operation of Redis has been configured, we will discuss the advanced features such as Master-slave and persistence strategy.

Run Redis

Redis-server/etc/redis.conf

# Check the run log, remember the log file we just configured?

Tail-100/var/log/redis.log

Ii. Configuring PHP

Then we compile Phpredis, the project address

Download

git clone https://github.com/phpredis/phpredis.git Phpredis
CD Phpredis
/usr/local/php/bin/phpize
./configure

# The old high environment variable is not imported so the compile command is./configure--with-php-config=/usr/local/php/bin/php-config
Make && make install

If your PHP is not compiled, then phpize needs to perform yum install Php-devel, that is, install the devel version of PHP
When the compilation is complete, you will get

Installing Shared extensions:/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

We'll copy it out.

cp/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/redis.so/usr/local/php/lib/php/extensions/

Open Redis Extension

Similar to the PHP installation memcached extension, finally we need to add the following configuration in php.ini

Vim/etc/php.ini

# add

[Redis]
Extension=redis.so

After restarting Apache or PHP-FPM, the Phpinfo page
