Use Redis database storage SessionID on Ubuntu and implement session sharing

Ubuntu used on Redis Database storage SessionID and implementation Session shared

First part: Installation and configuration Redis Database

installation Redis database server. See also:http://grainier.net/how-to-install-redis-in-ubuntu/

Redis official website: https://redis.io/

$ wget http://download.redis.io/releases/redis-3.2.8.tar.gz

$ tar xzf redis-3.2.8.tar.gz

$ CD redis-3.2.8

$ make

$ make Test

$ cat/sys/kernel/mm/transparent_hugepage/enabled// display current THP enabled status

$ sudo su switches to root and then # echo never >/sys/kernel/mm/transparent_hugepage/enabled toggle THP State. Can add it to your/etc/rc.local on order to retain the setting after a reboot.

$ sudo make install// Copy the compiled executable file to the appropriate place to complete the installation.

The Redis main file functions as follows:

Redis-server:daemon boot program for Redis server

REDIS-CLI:Redis Command-line Operations tool. Of course, you can also use telnet to operate on its plain text protocol.

Redis-benchmark:redis Performance testing tool to test the read and write performance of Redis in your system and in your configuration

Redis-stat:redis Status Detection Tool to detect Redis current status parameters and delay status

Use Help:

$ CD Utils

$ sudo./install_server.sh

set the appropriate parameters ( You can change the default port6379 to another value, such as 6535).

port:6535

Config File:/etc/redis/6535.conf

Log File:/var/log/redis_6535.log

Data dir:/var/lib/redis/6535

Executable:/usr/local/bin/redis-server

Cli executable:/USR/LOCAL/BIN/REDIS-CLI

command to use:

$ sudo service redis_6535 start

$ sudo service redis_6535 stop

$ sudo service redis_6535 restart

$ redis-server--help

Connect via client Redis Server:

$ redis-cli-p 6535// login

$ select 1// Select Database

$ keys *// list all keys

$ get key_name// Get value

Part II: Website Code ( placed in server-side main file www.js)

var session= require (' express-session '),

redisstore= require (' Connect-redis ') (session),// UseRedisDatabase StorageSessionInformation

redis= require ("Redis"),// Use Radis Client Node_redis

//================ set Redis database storage share session==================

rsclient= redis.createclient ({// create redis Client Instance

Host: ' 127.0.0.1 ',

port:6535,

db:1});

//==============Setsession (This article should be placed inPassportbefore)==============

Varsessionmiddleware = Session ({

Secret: ' Putyoursecrethere ',// Encrypt string , ' Putyoursecrethere ' can be changed to another string

Resave:true,
