Let PHP Session into Redis configuration method

• The first thing to do is to install Redis

Installation method: Http://redis.io/download

Installationdownload, extract and compile Redis with:$ wget http://download.redis.io/releases/redis-2.8.19.tar.gz$ tar XZF redis-2.8.19.tar.gz$ CD redis-2.8.19$ makethe binaries that is now compiled is available in the SRC directory. Run Redis with:$ Src/redis-serveryou can interact with Redis using the built-in client:$ src/redis-cliredis> set foo BA Rokredis> get foo "bar"

• Then install the phpredis extension redis.so

Installation Method Reference: Http://www.lecloud.net/post/3378834922/install-redis-php-extension-phpredis-with

The following code is the reference site installation method, please adjust according to your actual installation location,/////////////////////////////cd/usr/localsudo mkdir srccd/usr/local/srcsudo mkdir phpredis-buildcd phpredis-buildsudo git clone--depth 1 git://github.com/owlient/ Phpredis.gitcd phpredissudo Phpizesudo./configuresudo makesudo make install Cd/usr/local/lib/php5/sudo gedit PHP.ini if Extension_dir is not configured, configure the path to your extension CP redis.so/usr/local/lib/php5/extension/join a line: Extension = redis.so Restart Nginx and php-fpm to output phpinfo to see Redis extension installation Complete

• Set PHP.ini

Find Session.save_handler = Files This line, modified to Session.save_handler = Redis, the original session storage method to micro-redis way to improve speed, The reason is that Redis is a bit faster in memory reading than in file reads

Find Session.save_path = "/tmp" this line, modified to Session.save_path = "tcp://127.0.0.1:8888", which is pointing to the local TCP service, This service will be launched by our redis.

Restart Nginx and PHP-FPM output phpinfo can see the session save way and path has changed

• Start Redis Service

  Redis-server--port 8888 &

  Writing PHP code

  <?php header ("Content-type:text/html;charset=utf-8"); Session_Start ();//This is important $_session[' test_session ']= @array (' name ' = ' fanqie ', ' CCC ' = ' Hello Redis '); $redis = new Redis (), $redis->connect (' 127.0.0.1 ', 8888); Echo ' sessionid>>>>>>> phpredis_ SESSION: '. SESSION_ID (); Echo ' <br/> '; Echo ' <br/> ';//redis uses session_id as key and is a string to store the echo ' Redis get > through PHP >>>>>> '. $redis->get (' phpredis_session: '. session_id ()); Echo ' <br/> '; Echo ' <br/> ' Echo ' Get >>>>>>><br/> ' via PHP, Echo ' <pre> '; Var_dump ($_session[' Test_ Session ']); Echo ' </pre> ';

  Page output, we can see that we have successfully stored and successfully acquired the stored value through Redis

  Sessionid>>>>>>> phpredis_session:fmd75d3dfrlkp43eh567f7dsi5 via PHP with Redis get >>>> >>>test_session|a:2:{s:4: "Name"; s:6: "Fanqie"; s:3: "CCC"; s:12: "Hello Redis";} Get >>>>>>>array (2) {  ["name"]=>  string (6) "Fanqie"  ["CCC"] with the session via PHP]=>  string (+) "Hello Redis"}

  Use the Redis client to see that a record of Hello Redis has been stored in the Redis library
