[root@redis phpredis-develop]# /usr/local/php/bin/phpize 
[root@redis phpredis-develop]# ./configure --with-php-config=/usr/local/php/bin/php-config 
[root@redis phpredis-develop]# make && make install

        编辑 /usr/local/php/etc/php.ini

[root@redis ~]# vim /usr/local/php/etc/php.ini

        增加一行extension = redis.so

         PHP-redis中文文档

2. redis 实现 session 共享

        php.ini中加入（不建议）

1
2
session.save_handler = "redis"
session.save_path = "tcp://127.0.0.1:6379"

        或者apache虚拟主机加入

1
2
php_value session.save_handler "redis"
php_value session.save_path "tcp://127.0.0.1:6379"

03

        或者php-fpm.conf对应的pool中加入

1
2
php_value[session.save_handler] = redis
php_value[session.save_path] = " tcp://127.0.0.1:6379 "

3. redis 储存 session 测试

[root@redis ~]# wget http://study.lishiming.net/.mem_se.txt
[root@redis ~]# mv .mem_se.txt /usr/local/apache2/htdocs/session.php
