Learn about installing redis extension for php7 in centos7

Recommended (free): PHP7

Download redis

Download redis, unzip and compile:

$ wget http://download.redis.io/releases/redis-4.0.6.tar.gz$ tar xzf redis-4.0.6.tar.gz
$ cd redis-4.0.6$ make && make PREFIX=/usr/local/redis install  #安装到指定目录

Now go to the source directory where the tar package was extracted just now, copy a redis.conf configuration file, and put it in / In the usr/local/redis/bin/ directory

##Enter the redis directory and run vi redis.conf

Start the Redis service through the following command:
##./bin/redis-server ./redis.conf

You can use the built-in client command redis-cli:

$ ./redis-cli
redis> set foo bar
OK
redis> get foo"bar"

The above is to install the redis program

To enable the redis extension in php7

Use git clone to download git phpredis extension package

[root@localhost local ]#git clone  https://github.com/phpredis/phpredis.git

//Specific Which one to use depends on the directory where your phpize file is located. In this case, you should use whereis phpize to view the path

[
root@localhost local
 ]
# whereis phpize
phpize: /usr/bin/phpize /usr/share/man/man1/phpize.1.gz

这里表明路径为/usr/bin/phpize,然后执行:

[
root@localhost phpredis
 ]
# /usr/bin/phpize
Can't find PHP headers in /usr/include/php
The php-devel package is required for use of this command.

这里报错了，原因是没有安装好php-devel，由于我是使用的php7.0所以执行以下命令：

[root@localhost phpredis]#yum -y install php70w-devel

然后再次执行：

[root@localhost phpredis]# /usr/bin/phpize
Configuring for:
PHP Api Version: 20151012
Zend Module Api No: 20151012
Zend Extension Api No: 320151012

执行完上一步，我们就有了 configure 配置文件了，接下来配置

[root@localhost phpredis]#./configure

或者执行

[root@localhost phpredis]#./configure --with-php-config=/usr/bin/php-config

接下来是编译安装

[root@localhost phpredis]#make 
[root@localhost phpredis]# make install
 Installing shared extensions:      /usr/local/php/lib/php/extensions/no-debug-non-zts-20170718/

配置php的配置文件php.ini（具体放在那里可以用 whereis php.ini 来查看）,我的配置文件php.ini在/etc/下

[root@localhost phpredis]#vim /etc/php.ini

开启redis扩展：

extension = redis.so

redis.so文件的路径可以在make install的时候看到

[root@localhost local]# php -m  #查询php的扩展

重启nginx服务器，重启php-fpm,使配置生效

重启之后我们打开info.php,已经可以看到redis的扩展信息了
