一，下载phpredis
1，官方下载地址:
https://github.com/phpredis/phpredis/releases
2，wget下载
[root@yjweb source]# wget https://github.com/phpredis/phpredis/archive/5.2.0.tar.gz
说明：刘宏缔的架构森林是一个专注架构的博客，地址：https://www.cnblogs.com/architectforest
对应的源码可以访问这里获取： https://github.com/liuhongdi/
说明：作者:刘宏缔 邮箱: 371125307@qq.com
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 redis Redis Support => enabled Redis Version => 5.2.0 Redis Sentinel Version => 0.1 Available serializers => php, json Directive => Local Value => Master Value redis.arrays.algorithm => no value => no value redis.arrays.auth => no value => no value redis.arrays.autorehash => 0 => 0 redis.arrays.connecttimeout => 0 => 0 redis.arrays.distributor => no value => no value redis.arrays.functions => no value => no value redis.arrays.hosts => no value => no value redis.arrays.index => 0 => 0 redis.arrays.lazyconnect => 0 => 0 redis.arrays.names => no value => no value redis.arrays.pconnect => 0 => 0 redis.arrays.previous => no value => no value redis.arrays.readtimeout => 0 => 0 redis.arrays.retryinterval => 0 => 0 redis.arrays.consistent => 0 => 0 redis.clusters.cache_slots => 0 => 0 redis.clusters.auth => no value => no value redis.clusters.persistent => 0 => 0 redis.clusters.read_timeout => 0 => 0 redis.clusters.seeds => no value => no value redis.clusters.timeout => 0 => 0 redis.pconnect.pooling_enabled => 1 => 1 redis.pconnect.connection_limit => 0 => 0 redis.session.locking_enabled => 0 => 0 redis.session.lock_expire => 0 => 0 redis.session.lock_retries => 10 => 10 redis.session.lock_wait_time => 2000 => 2000
六，查看本地centos的版本
[webop@yjweb ~]$ cat /etc/redhat-release
CentOS Linux release 8.0.1905 (Core)
