centos8平台php7.4.2安装phpredis实现对redis的访问

一，下载phpredis

[root@yjweb source]# wget https://github.com/phpredis/phpredis/archive/5.2.0.tar.gz

二，解压：

[root@yjweb source]# tar -zxvf 5.2.0.tar.gz 

三，安装phpredis

1，phpize

说明：phpize的作用：检查php环境，为扩展生成configure文件

[root@yjweb source]# cd phpredis-5.2.0/
[root@yjweb phpredis-5.2.0]# /usr/local/soft/php7/bin/phpize
Configuring for:
PHP Api Version:         20190902
Zend Module Api No:      20190902
Zend Extension Api No:   320190902

2，配置,要指定php-config的所在路径

[root@yjweb phpredis-5.2.0]# ./configure --with-php-config=/usr/local/soft/php7/bin/php-config

3,安装

[root@yjweb phpredis-5.2.0]# make && make install;

说明：注意安装完成后提示的路径：

Installing shared extensions:     /usr/local/soft/php7/lib/php/extensions/no-debug-non-zts-20190902/

我们在添加模块时要用到

四，配置php.ini,引入redis模块

[root@yjweb phpredis-5.2.0]# vi /usr/local/soft/php7/etc/php.ini

添加一行:

extension=/usr/local/soft/php7/lib/php/extensions/no-debug-non-zts-20190902/redis.so 

五，重启服务，检查安装是否成功

1,重启

[root@yjweb phpredis-5.2.0]# systemctl stop php-fpm
[root@yjweb phpredis-5.2.0]# systemctl start php-fpm 

2，从浏览器检查安装是否成功

在documentroot目录下，增加一个phpinfo.php页面，

从浏览器访问，从phpinfo页面搜索 redis,

找到后说明安装成功

phpinfo.php页面的代码：

<?php
phpinfo();
?>

3,从命令行检查安装是否成功

看到redis模块，说明安装成功

[root@yjweb phpredis-5.2.0]# /usr/local/soft/php7/bin/php --ri redis
