安装redis

[@zjm_46_98 ~]# mkdir /opt/java/redis
[@zjm_46_98 ~]# cd /opt/java
[@zjm_46_98 /opt/java]# wget http://redis.googlecode.com/files/redis-2.6.14.tar.gz
[@zjm_46_98 /opt/java]# tar zxvf redis-2.6.14.tar.gz
[@zjm_46_98 /opt/java]# cd redis-2.6.14
[@zjm_46_98 /opt/java/redis-2.6.14]# make PREFIX=/opt/java/redis install

安装redis成功后，你可以在/opt/java/redis/bin的目录看到下面五个文件

[@zjm_46_98 /opt/java/redis-2.6.14]# ls /opt/java/redis/bin
redis-benchmark  redis-check-aof  redis-check-dump  redis-cli  redis-server

redis服务自动启动
```
[@zjm_46_98 /opt/java/redis-2.6.14]# cd /etc/rc.d/init.d/
[@zjm_46_98 /etc/rc.d/init.d]# cp /opt/java/redis-2.6.14/utils/redis_init_script /etc/rc.d/init.d/redis
[@zjm_46_98 /etc/rc.d/init.d]# chkconfig --add redis
service redis does not support chkconfig
```
如果出现service redis does not support chkconfig问题，解决办法如下：
其中# chkconfig: 2345 80 90 说明redis服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是80，关闭的优先级是90
EXEC：redis服务地址
CLIEXEC：redis客户端地址
$EXEC $CONF & 注意后面的那个“&”，即是将服务转到后面运行的意思，否则启动服务时，Redis服务将占据在前台，占用了主用户界面，造成其它的命令执行不了。

[@zjm_46_98 /etc/rc.d/init.d]# vim redis
#!/bin/sh
# chkconfig: 2345 80 90
# description:  Redis is a persistent key-value database
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

REDISPORT=6379
EXEC=/opt/java/redis/bin/redis-server
CLIEXEC=/opt/java/redis/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

将redis配置文件拷贝到/etc/redis/${REDISPORT}.conf
```
[@zjm_46_98 /etc/rc.d/init.d]# mkdir /etc/redis
[@zjm_46_98 /etc/rc.d/init.d]# cp /opt/java/redis-2.6.14/redis.conf /etc/redis/6379.conf
```
这样，redis服务脚本指定的CONF就存在了。默认情况下，Redis未启用认证，可以通过开启6379.conf的requirepass 指定一个验证密码

启动服务并验证

[@zjm_46_98 /etc/rc.d/init.d]# chkconfig --add redis
[@zjm_46_98 /etc/rc.d/init.d]# service redis start
Starting Redis server...
[@zjm_46_98 /etc/rc.d/init.d]# vi /etc/profile
	export PATH=$PATH:/opt/java/redis/bin
[@zjm_46_98 /etc/rc.d/init.d]# source /etc/profile
[@zjm_46_98 /opt/java]# redis-cli
redis 127.0.0.1:6379> ping
PONG
redis 127.0.0.1:6379> quit
