Detailed explanation of Redis shared session

This time I will bring you a detailed explanation of Redis sharing Session, what are the precautions for Redis sharing Session, the following is a practical case, let's take a look.

1. When the number of visits to the system increases, using Redis to save the Session can improve the performance of the system, and also facilitates the sharing of the Session when multiple machines are under load

1 .Open config/database.php. Add session connection in redis

  'session' => [
    'host' => env('REDIS_HOST', '127.0.0.1'),
    'password' => env('REDIS_PASSWORD', null),
    'port' => env('REDIS_PORT', 6379),
    'database' => 10,
  ],

2. Open config/session.php and fill in the above redis connection

'connection' => 'session',

3. Modify env and use redis to access Sessoin

SESSION_DRIVER=redis

Now access the system. The session has been saved using redis. About 15% performance improvement (current project)

2. Redis access configuration. In order to use other servers to access redis, you need to configure redis remote access

1. Open /etc/redis.conf and modify the bind information. For example, the current server LAN IP is 10.0.0.2

bind 127.0.0.1 10.0.0.2

2. Modify protected-mode

protected-mode no

3. Reload redis configuration

service redis-server reload

4. Register and check whether iptable has opened port 6379 for access

iptables -I INPUT -s 10.0.0.2 -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT

5. Other servers modify env

REDIS_HOST=10.0.0.2

Now other servers The redis server can be accessed.
