##### 操作环境 #####

服务器centos7.3, ip:47.52.41.245，所包含的集群节点有7003,7004,7005

开启防火墙

systemctl eable firewalld.service

##### redis集群设置开启自启动 #####

这里是设置的是集群里面某个redis节点开机启动，没有使用集群，这里设置的是7003服务

1。 根据启动脚本要求，将某个节点的配置文件以端口为名复制一份到指定目录，这里复制到/etc/redis\_cluster

cd /etc
    mkdir redis_cluster
    cd redis_cluster
    cp /tmp/frank/redis/redis-3.2.1/redis_cluster/* /etc/redis_cluster/

2。 在/etc/init.d目录下面新建启动脚本并且命名为redis7003

vim redis7003

完整配置信息为

#!/bin/sh
    #
    # Simple Redis init.d script conceived to work on Linux systems
    # as it does use of the /pro filesystem.
    # chkconfig:2345 90 10
    # description:Redis is a persistent key-value database
    
    REDISPORT=7003
    EXEC=/tmp/frank/redis/redis-3.2.1/src/redis-server
    CLIEXEC=/tmp/frank/redis/redis-3.2.1/src/redis-cli
    
    PIDFILE=/var/run/redis_${REDISPORT}.pid
    CONF="/etc/redis_cluster/${REDISPORT}/redis.conf"
    
    case "$1" in
        start)
        if [ -f $PIDFILE ]
        then
            echo "$PIDFILE exists,process is already running or crashed"
        else
            echo "Starting Redis server $REDISPORT ..."
            $EXEC $CONF
        fi  
        ;;
        stop)
        if [ ! -f $PIDFILE ]
        then
            echo "$PIDFILE does not exit,process is not running"
        else
            PID=$(cat $PIDFILE)
            echo "Stopping"
            $CLIEXEC -p $REDISPORT shutdow
            while [ -x /proc/${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

3。修改启动文件的权限

chmod +x /etc/init.d/redis7003

4。 设定开机启动服务

chkconfig redis7003 on

5。启动,停止redis

service redis start   #或者 /etc/init.d/redis start 
    service redis stop   #或者 /etc/init.d/redis stop

6。 reboot重启服务器

7。测试服务是否启动

[root@iZj6c7eeosj2t5vjw8rf4xZ init.d]# redis-cli -c -p 7003
    127.0.0.1:7003>

8。其余节点按上面步骤继续
