第1章 一、安装redis

1、下载redis包
wget http://download.redis.io/releases/redis-3.2.1.tar.gz
2、解压redis包到/opt下
tar -zxvf /home/redis-3.2.1.tar.gz -C /opt
3、安装并测试redis
cd /opt/redis-3.2.1/src
make && make install

二、配置redis

1、复制并修改配置文档
cp /opt/redis-3.2.1/redis.conf /etc/
vi /etc/redis.conf
#开启redis远程访问
#将 bind 127.0.0.1改为 bind 0.0.0.0
#开启redis守护进程
#根据需求，可配置redis是否进行持久化：修改save策略
#添加密码访问 requirepass password
2、将redis配置进系统服务
vi /etc/init.d/redis
/etc/init.d/redis内容如下
#chkconfig:   2345 90 10  
  
# description:  Redis is a persistent key-value database

        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 $REDISPORT SHUTDOWN
                #若有密码则加上密码
                #$REDIS_CLI -a $PASSWORD -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  
##############################
#给redis文件加上执行权限
chmod +x /etc/init.d/redis
3、设置redis服务开机启动
chkconfig redis on
4、在防火墙中开放redis端口
vi /etc/sysconfig/iptables
#加入下面的端口配置
-A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT
#重启防火墙
service iptables restart
5、启动、关闭和重启redis服务
service redis start
service redis stop
service redis restart

三、使用redis

#进入redis命令行
redis-cli -a password
 3.master配置了密码，slave如何
