Redis实现session共享

php.ini中加入    #容易出错不建议。

session.save_handler = "redis" 

session.save_path = "tcp://127.0.0.1:6379" 

或者apache虚拟主机加入  #可以放到最后。

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

或者php-fpm.conf对应的pool中加入

php_value[session.save_handler] = redis

php_value[session.save_path] = " tcp://127.0.0.1:6379 "

Redis存储session测试   #注意redis是否有密码否则容易出错。

wget http://study.lishiming.net/.mem_se.txt

mv .mem_se.txt  /usr/local/apache2/htdocs/session.php

curl localhost/session.php

连接redis 

/usr/local/redis/bin/redis-cli

127.0.0.1:6379> keys * //可以把所有的key都列出来

"PHPREDIS_SESSION:9jm6nom9ogojedj3pth0iscv22"

127.0.0.1:6379> get PHPREDIS_SESSION:9jm6nom9ogojedj3pth0iscv22

"TEST|i:1443710814;TEST3|i:1443710814;"
