Centos系统安装 phpredis 扩展

Git地址：https://github.com/nicolasff/phpredis

一、安装：

phpize
./configure
make && make install

其中，添加PHP扩展需要用到 phpize，所以我们需要安装 php-devel 这个包。

1. yum install php-devel
2. 然后编译安装phpredis：
3. git clone git://github.com/nicolasff/phpredis.git
4. cd phpredis
5. phpize
6. ./configure --with-php-config=/usr/bin/php-config --enable-redis
7. make
8. make install

安装成功后，模块会被安装到系统上，显示如下：

1. Installing shared extensions:     /usr/lib64/php/modules/
2. 执行：ls  /usr/lib64/php/modules/
3. 显示有：redis.so

编辑配置文件：php.ini ：

[plain] view
plaincopyprint?

1. extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626"        //PHP扩展路径
2. ; Enable redis extension module
3. extension=redis.so                      //开启redis扩展

最后重启WEB服务器即可！

二、测试：

在命令行里执行：php -m ；发现有redis，表明扩展安装成功！

写个测试脚本：

[php] view
plaincopyprint?

1. <?php
2. $redis = new Redis();
3. $redis->connect('127.0.0.1', '6379');
4. for($i = 0; $i < 100; $i++) {
5. echo  $redis->ping();
6. }

结果输出：
