PHP7 adds redis extension

1. Purpose:

　Recently deployed a new environment, I use PHP7+nginx. The old version of NoSQL uses memcache. I plan to use redis in the new version, so I installed the redis extension.

2.Description:

In fact, there is nothing to pay attention to when installing redis extension , the main thing is to pay attention to whether the extension supports the PHP version when downloading the extension. Other installation methods are the same as the usual PHP extension installation methods.

3. Installation steps:

　1. Download

Download address: http://pecl. php.net/package/redis

## I put the download directory under /data/download/php

cd to the download directory, download: wget http://pecl.php.net/get/redis-3.1.2.tgz

##　2. Unzip

　Unzip to the current Directory tar -zxvf redis-3.1.2.tgz

　3. Installation

　cd redis-3.1.2 directory

Use phpize to generate the configure configuration file in this directory: directly run /usr/local/php7/bin/phpize

Then configure, compile and install All completed in this directory

　./configure --with-php-config=/usr/local/php7/bin/php-config

　make

　make install

　After make install, you will see Installing shared extensions: /usr/local/php7/lib/php /extensions/no-debug-non-zts-20160303/

## This directory is the directory where the redis.so file is generated

ll /usr /local/php7/lib/php/extensions/no-debug-non-zts-20160303/

Seeing redis.so means the installation is successful

4. Configure to support PHP7:

vim /usr/local/php7/etc/php.ini

Add extension =redis.so

　:wq!

5. Restart nginx, actually restart php-fpm
