php使用redis存储

一、Redis扩展模块

# wget https://codeload.github.com/phpredis/phpredis/zip/develop -O phpredis.zip

# unzip phpredis.zip

# cd phpredis-develop/

# /usr/local/php/bin/phpize

# ./configure --with-php-config=/usr/local/php/bin/php-config

# make

# make install

二、配置php.ini添加redis.so

# vim /usr/local/php/etc/php.ini

加入：

extension = redis.so

检测是否配置成功：

# /usr/local/php/bin/php -m | grep redis

如果出现redis说明配置成功

三、Redis实现session共享

在lamp/lnmp环境下实现的通用配置

编辑php.ini添加下面两行

session.save_handler = "redis"

session.save_path = "tcp://191.168.1.203:6379"

或者编辑httpd.conf中对应的虚拟主机添加：

php_value session.save_handler "redis"

php_value session.save_path " tcp://191.168.1.203:6379"

或者php-fpm.conf对应的pool中添加

php_value[session.save_handler] = redis

php_value[session.save_path] = " tcp://191.168.1.203:6379"

四、Redis存储session测试

http://www.test.com/session.php

1462905233
1462905648
r0nrs2en0oor7nbsr1tkoqeo30

[root@server2 etc]#
redis-cli

127.0.0.1:6379> keys *

1)
"PHPREDIS_SESSION:r0nrs2en0oor7nbsr1tkoqeo30"

127.0.0.1:6379> get
PHPREDIS_SESSION:r0nrs2en0oor7nbsr1tkoqeo30

"TEST|i:1462905233;TEST3|i:1462905648;"
