本机连不上虚拟机的redis

首先修改redis.conf

1. bind 改为0.0.0.0，设置所有机器可访问
2. 查看requirepass，可设置也可不设置（开发环境）

查看6379端口是否开启

1. 输入firewall-cmd --query-port=6379/tcp，如果返回no说明没有开启
2. 输入firewall-cmd --add-port=6379/tcp （加 --permanent 永久有效），返回success说明开启成功

设置开机启动

1. 在redis目录中找到redis_init_script文件
   我的文件地址是在：/usr/local/redis/utils
2. 按实际情况修改redis_init_script相关参数，就是redis-server、redis-cli、redis.conf文件的目录，PIDFILE这个参数在安装redis的时候就已经有了，不需要动。

#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database

REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid
CONF="/opt/conf/redis/${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

3. 将redis_init_script脚本复制到/etc/init.d目录下，注意增加了chkconfig和description两行，不然会提示服务redis不支持chkconfig

cp redis_init_script /etc/init.d/redis

4. 设置为开机自启动服务器

#
chkconfig redis on 
#打开服务
service redis start
#关闭服务
service redis stop
