1.下载redis扩展包
wget http://pecl.php.net/get/redis-5.2.0.tgz
2.解压
tar -zxf redis-5.2.0.tgz
3.切换到解压目录
cd redis-5.2.0
3.运行phpize
/usr/local/php/bin/phpize
4.使用 ./configure 进行配置
./configure --with-php-config=/usr/local/php/bin/php-config
5.安装
make && make install
安装成功会出现下面这行,这就是扩展所在的路径
Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20180731/
6.修改php.ini,把redis扩展加进去
vim /usr/local/php/etc/php.ini
把下面这两行加到php.ini里面
extension_dir = /usr/local/php/lib/php/extensions/no-debug-non-zts-20180731/
extension = redis.so
extension = redis.so
7.重启一下php,这样扩展就安装好了
kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`
8.查看扩展是否安装成功,如果看到redis就说明安装成功了
php -m
