go链接redis错误：A connection attempt failed because the connected

package main

import (
	"fmt"
	"github.com/garyburd/redigo/redis"
)

func main() {
	conn, err := redis.Dial("tcp", "192.168.5.104:6379")
	if err != nil {
		fmt.Println("redis.Dial err = ", err)
		return
	}
	defer conn.Close()

	_, err = conn.Do("Set", "name", "tomje 猫")
	if err != nil {
		fmt.Println("Set err = ", err)
		return
	}

	r, err := redis.String(conn.Do("Get", "name"))
	if err != nil {
		fmt.Println("Get err = ", err)
		return
	}
	fmt.Println(" *** 作OK  :", r)
}

 这个错误应该是网络问题的，查看服务器的防火墙

#关闭防火墙
@localhost ~]# systemctl stop firewalld
@localhost ~]# systemctl disable firewalld
@localhost ~]# systemctl status firewalld
