Redis

It is also easy to install Redis under CentOS. You can follow step by step without making any mistakes.

1, switch to /usr/src directory (if you install in a different directory, please note that you need to change some paths later), download Redis, the latest version is 2.8.13
d /usr/src

wget http://download.redis.io/releases/redis-2.8.13.tar.gz

2. Unzip and switch directories

tar xzf redis-2.8.13.tar.gz
cd redis-2.8.13

3, compile,

make
make install

4. Open redis.conf to modify the configuration file. The most important thing is the following lines.

daemonize yes
loglevel notice
logfile /var/log/redis.log
dir ./

5. Set overcommit_memory of the system and execute

vi /etc/sysctl.conf

Add 1 line to the file and save:

vm.overcommit_memory = 1

Perform:

sysctl vm.overcommit_memory=1

6. Add startup script and execute:

vi /etc/init.d/redis

Write the following code to save:

#!/bin/sh
#
# redis    Startup script for Redis Server
#
# chkconfig: - 90 10
# description: Redis is an open source, advanced key-value store. 
#
# processname: redis-server
# config: /etc/redis.conf
# pidfile: /var/run/redis.pid
 
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
REDIS_CLI=/usr/local/bin/redis-cli
 
PIDFILE=/var/run/redis.pid
CONF="/usr/src/redis-2.8.13/redis.conf"
 
case "$1" in
  start)
    if [ -f $PIDFILE ]
    then
        echo "$PIDFILE exists, process is already running or crashed"
    else
        echo "Starting Redis server..."
        $EXEC $CONF
    fi
    if [ "$?"="0" ] 
    then 
       echo "Redis is running..."
    fi 
    ;;
  stop)
    if [ ! -f $PIDFILE ]
    then
        echo "$PIDFILE does not exist, process is not running"
    else
        PID=$(cat $PIDFILE)
        echo "Stopping ..."
        $REDIS_CLI -p $REDISPORT SHUTDOWN
        while [ -x ${PIDFILE} ]
        do
          echo "Waiting for Redis to shutdown ..."
          sleep 1
        done
        echo "Redis stopped"
    fi
    ;;
  restart|force-reload)
    ${0} stop
    ${0} start
    ;;
 *)
  echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
    exit 1
esac

Set permissions and boot:

chmod +x /etc/init.d/redis
chkconfig --add redis
chkconfig redis on

ok, now installed. Start redis use < code > service redis start < / code > or < code > / etc/init d/redis start < / code >, Stop redis command < code > service redis stop < / code > or < code > / etc/init d/redis stop < / code >, under windows system using redis can refer to this article.

The following will be displayed:

tar xzf redis-2.8.13.tar.gz
cd redis-2.8.13
