redis安装、设置密码及开机自启动

一、redis安装

1、tar xzf redis-2.8.3.tar.gz
2、cd redis-2.8.3
3、make
4、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。然后拷贝到一个目录下。
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


5、启动Redis服务
./redis-server redis.conf 


以用shutdown来停止Redis实例，具体命令为src/redis-cli shutdown。

二、开机自启动

1、设置Redis.conf中daemonize为yes,确保守护进程开启；
     找到#requirepass foorbared这一行，直接替换掉这行，改为requirepass 新密码

2、编写开机自启动脚本

vi /etc/init.d/redis

脚本内容如下：

#!/bin/sh
# chkconfig: 2345 10 90  
# description: Start and Stop redis   

PATH=/usr/local/bin:/sbin:/usr/bin:/bin   
REDISPORT=6379  
EXEC=/alidata/soft/redis/redis-server   
REDIS_CLI=/alidata/soft/redis/redis-cli   

PIDFILE=/var/run/redis.pid   
CONF="/alidata/soft/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

3、写完后保存退出VI


4、设置权限

chmod 755 redis

5、启动测试

/etc/init.d/redis start

启动成功会提示如下信息：

Starting Redis server...
Redis is running...

6、设置开机自启动

chkconfig redis on

7、关机重启测试

reboot
