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 Installcd/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

 
  ' Fanqie ', ' CCC ' = ' Hello Redis '); $redis = new Redis (); $redis->connect (' 127.0.0.1 ', 8888); Echo ' sessionid>> >>>>> phpredis_session: '. SESSION_ID (); Echo '
'; Echo '
';//redis uses session_id as key and is a string to store echo ' using Redis for >>>>>>> ' via PHP. $redis->get (' Phpredis_session: '. SESSION_ID ()); Echo '
'; Echo '
' Echo ' gets >>>>>>> with session via PHP
'; Echo '
'; Var_dump ($_session[' test_session '); Echo '
';

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
