centos 安裝 redis

1、redis.io 上下載 redis安裝包（我下載的是2.8穩定版，3.0版本增加了數據庫集羣） https://github.com/antirez/redis/archive/2.8.23.tar.gz

2、解壓

tar xzf 2.8.23.tar.gz
cd redis-2.8.23
make

3、添加redis用戶

useradd redis  
mkdir -p /var/lib/redis  
mkdir -p /var/log/redis  
chown redis.redis /var/lib/redis  #後文用到的數據存放地址
chown redis.redis /var/log/redi  #後文用到的日誌存放地址

4、設置開機啓動項

將redis的配置文件複製到 /etc目錄中

cp redis.conf /etc

設置redis.conf文件

設置數據存放路徑：dir /var/lib/redis #默認爲./

設置日誌存放路徑：logfile "/var/log/redis/redis.log"  #默認爲空

設置redis後臺啓動：daemonize yes #默認爲no

設置init啓動腳本

#!bin/sh
# chkconfig: 2345 10 90  
# description: Start and Stop redis  
PATH=/usr/local/bin:/sbin:/usr/bin:/bin

REDISPORT=6379
EXEC=/usr/local/bin/redis-server
REDIS_CLI=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis.pid
CONF="/etc/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

將啓動腳本複製到 /etc/init.d/中

設置可執行權限
chmod +x /etc/init.d/redis 

設置開機啓動服務

chkconfig redis on

redis啓動命令：service redis start

redis停止命令： service redis stop
