Redis application Summary

1. Install

$ wget http://redis.googlecode.com/files/redis-2.6.14.tar.gz$ tar xzf redis-2.6.14.tar.gz$ cd redis-2.6.14$ make $ make install

Start the service:
/Usr/local/bin/redis-Server

Client command:
/Usr/local/bin/redis-cli

2. Configuration

In the source file redis-2.6.14/utils There Is A redis_init_script can be used as the redis Startup Script File

Redisport = 6379 # port number
Exec =/usr/local/bin/redis-Server
Cliexec =/usr/local/bin/redis-cli

Pidfile =/var/run/redis _ $ {redisport}. PID
Conf = "/usr/local/redis. conf" # configuration file address

Redisport = 6379 and conf can be modified.

There is a configuration file for redis. conf in the redis-2.6.14, which can be mainly configured

Port 6379 # port number

Daemonize yes # Run in the background

DIR/mnt/redisdata # configure where persistent files are stored

Maxclients 5000 # maximum number of client connections

Maxmemory 1500000000 # maximum memory usage <1.5G>

Requirepass mypass # Access Password

Then place the execution script and configuration file in a directory, as shown in figure

/Usr/local/redis/bin/redis_init_script
/Usr/local/redis. conf

3. Run and stop

Run/usr/local/redis/bin/redis_init_script start/usr/local/redis. conf

Stop/usr/local/redis/bin/redis_init_script stop/usr/local/redis. conf

4. Integration of spring and redis
