1.将下载好的压缩包放到/usr/local目录下

# tar xzf redis-3.0.2.tar.gz
    # cd redis-3.0.2 # make
    提示错误 make: cc: Command not found make: *** [adlist.o] Error 127
    没有安装gcc环境，需要安装gcc
    # yum install gcc
    安装后检查是否安装成功
    # rpm -qa |grep gcc
    之后重新make

2.编译完成后，在Src目录下，有四个可执行文件redis-server、redis-benchmark、redis-cli和redis.conf将其拷贝到一个目录下。

# mkdir /usr/redis
    # cp redis-server /usr/redis
    # cp redis-benchmark /usr/redis
    # cp redis-cli /usr/redis
    # cp redis.conf /usr/redis
    # cd /usr/redis

3.启动服务

# ./redis-server redis.conf
    提示错误 -bash :redis-server:command not found
    
    建立软连接
    # ln -s /usr/redis/redis-server /usr/bin/redis-server
    # ln -s /usr/redis/redis-cli /usr/bin/redis-cli
    重新启动
    # redis-server /usr/redis/redis.conf

启动成功

4.设置开机自启动

# vi /etc/init.d/redis

i#!/bin/bash
    # chkconfig: 2345 90 10
    
    # description: Redis is a persistent key-value database
    # chkconfig: 2345 10 90 
    # description: Start and Stop redis 
    PATH=/usr/local/bin:/sbin:/usr/bin:/bin   
    REDISPORT=6379  
    EXEC=/usr/local/redis/bin/redis-server   
    REDIS_CLI=/usr/local/redis/bin/redis-cli   
    PIDFILE=/var/run/redis.pid   
    CONF="/usr/local/redis/redis.conf"  
    #AUTH="1234" 
    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 exists, process is not running."  
                    else  
                            PID=$(cat $PIDFILE)   
                            echo "Stopping..."  
                           $REDIS_CLI -p $REDISPORT  SHUTDOWN    
                            sleep 2  
                           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

设置权限

# chmod 755 redis

启动

# /etc/init.d/redis start 
    提示错误 /etc/init.d/redis:permission denied
    
    # chmod a+x /etc/init.d/redis
    a+x 是给所有人加上可执行权限，包括所有者，所属组，和其他人
    o+x 只是给其他人加上可执行权限
    
    重新启动后显示
    Starting Redis server... 
    Redis is running ...

设置开机自启动

# chkconfig redis on
    提示错误 service redis does not support chkconfig
    
    把下面两行注释放在/etc/init.d/redis文件靠前的注释中：
    # chkconfig: 2345 90 10
    
    # description: Redis is a persistent key-value database

关机重启测试

5.设置启动redis为后台启动  
平时我们启动是这样的：

如果按ctrl+c退出后，则关闭了.  
如果要设置redis后台启动，则需要修改redis.config文件，修改这里

英文大概意思默认情况下复述,不作为守护进程运行。如果你需要使用“是”。

再次启动OK
