Configure PHP session storage to Redis for multiple servers sharing session

PHP sessions are in the form of files by default and can be configured into NoSQL for session sharing, such as sharing sessions in a server cluster

The configuration is as follows:

Method One: Modify the settings of the php.ini

Session.save_handler ="tcp://127.0.0.1:6379"

After modifying, restart the PHP-FPM.

Pkill php-fpmphp-fpm

Mode two: set by Ini_set () function

Ini_set ("Session.save_handler", "Redis"); Ini_set ("Session.save_path", "tcp://127.0.0.1:6379");

If the configuration file/etc/redis.conf set the connection password Requirepass, save the session will be error, Save_path so write tcp://127.0.0.1:6379?auth=authpwd can.

Test code:

<?PHP//if PHP.ini is configured, the following two lines comment out Ini_set (' Session.save_handler ', ' Redis '); Ini_set (' Session.save_path ', ' tcp:// 127.0.0.1:6379 '); Session_Start();$_session[' sessionid '] = ' This is session content! ';Echo $_session[' SessionID '];Echo' <br/> '; $redis=NewRedis ();$redis->connect (' 127.0.0.1 ', 6379); //Redis uses session_id as the key and is stored as a stringEcho $redis->get (' phpredis_session: '.session_id());
