centos 安装 redis

1、redis.io 上下载 redis安装包（我下载的是2.8稳定版，3.0版本增加了数据库集群） https://github.com/antirez/redis/archive/2.8.23.tar.gz

2、解压

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

3、添加redis用户

useradd redis  
mkdir -p /var/lib/redis  
mkdir -p /var/log/redis  
chown redis.redis /var/lib/redis  #后文用到的数据存放地址
chown redis.redis /var/log/redi  #后文用到的日志存放地址

4、设置开机启动项

将redis的配置文件复制到 /etc目录中

cp redis.conf /etc

设置redis.conf文件

设置数据存放路径：dir /var/lib/redis #默认为./

设置日志存放路径：logfile "/var/log/redis/redis.log"  #默认为空

设置redis后台启动：daemonize yes #默认为no

设置init启动脚本

#!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

将启动脚本复制到 /etc/init.d/中

设置可执行权限
chmod +x /etc/init.d/redis 

设置开机启动服务

chkconfig redis on

redis启动命令：service redis start

redis停止命令： service redis stop
