阿里云LINUX服务器redis安装详解

第一部分：安装redis 

      安装环境：系统centos 6.4 

      安装目录：

/usr/local/redis

 首先到Redis官网下载安装包，或者直接使用如下命令下载：

wget http://download.redis.io/releases/redis-3.0.7.tar.gz

    解压到安装目录后执行 make命令：

 

[root@ser211 local]# tar -vxzf redis-3.0.7.tar.gz  
[root@ser211 redis]# make 

    测试是否安装成功,执行一下命令：

   

[root@ser211 redis]# ./usr/local/redis/src/redis-server  
[root@ser211 init.d]# redis-server

   到这步，Redis安装成功！

第二部分：配置redis并添加到服务 

     将/usr/local/redis/utils/redis_init_script脚本拷贝到/etc/init.d/redis

  

[root@ser211 init.d]# cp /usr/local/redis/utils/redis_init_script /etc/init.d/redis  

    将脚本文件做如下修改：

#!/bin/sh  
#chkconfig: 2345 80 90  
# Simple Redis init.d script conceived to work on Linux systems  
# as it does use of the /proc filesystem.  
  
REDISPORT=6379  
EXEC=/usr/local/bin/redis-server  
CLIEXEC=/usr/local/bin/redis-cli  
  
PIDFILE=/var/run/redis_${REDISPORT}.pid  
CONF="/etc/redis/${REDISPORT}.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  
        ;;  
    stop)  
        if [ ! -f $PIDFILE ]  
        then  
                echo "$PIDFILE does not exist, process is not running"  
        else  
                PID=$(cat $PIDFILE)  
                echo "Stopping ..."  
                $CLIEXEC -p $REDISPORT shutdown  
                while [ -x /proc/${PID} ]  
                do  
                    echo "Waiting for Redis to shutdown ..."  
                    sleep 1  
                done  
                echo "Redis stopped"  
        fi  
        ;;  
    *)  
        echo "Please use start or stop as first argument"  
        ;;  
esac  

   根据脚本文件中的配置，创建数据目录/var/redis/6379,将redis-server、redis-cli移动到/usr/local/bin下，将/usr/local/redis/redis.conf移动到/etc/redis/6379.conf,并做如下修改：

daemonize yes //由no改为yes，以后台方式运行  
dir /var/redis/6379 //配置数据库文件存放目录  

 最后将redis添加为服务：

[root@ser211 init.d]#  chkconfig --add redis

   运行：

[root@ser211 redis]# service redis start  
Starting Redis server...  
[root@ser211 redis]# redis-cli  
127.0.0.1:6379> get a   
"1"  
127.0.0.1:6379>   
[root@ser211 init.d]# service redis stop  
Stopping ...  
Redis stopped 

好了，配置完成！！！
