修改配置文件

设置后台启动

将redis.conf配置文件中里面的daemonize no 改成 yes

daemonize yes

设置远程访问

将redis.conf配置文件中里面的bind 那一行注释掉

#bind 127.0.0.1 -::1

关闭保护模式

将本机访问保护模式设置no

protected-mode no

设置密码

requirepass 密码

举例:设置密码为123456
requirepass 123456

设置Redis最大内存

一般推荐Redis设置内存为最大物理内存的四分之三，单位是字节（byte）
#这里设置为1GB
maxmemory 1073741824

添加防火墙规则

如果是从网上租的服务器,需要添加添加防火墙规则

这里以腾讯云服务器举例

防火墙开放端口

进入linux将6379防火墙放开,然后重新连接试试

#检查防火墙状态
firewall-cmd --state

#开启防火墙
systemctl restart firewalld.service

#开启6379端口
firewall-cmd --zone=public --add-port=6379/tcp --permanent

#重新载入配置
firewall-cmd --reload

#查看已开放的端口
firewall-cmd --list-ports

后台启动redis

切换到redis-server所在的目录下,执行以下命令来启动redis

redis-server /usr/local/redis-6.2.7/redis.conf

这里的/usr/local/redis-6.2.7/redis.conf是我的redis配置文件路径,要改成自己的

测试连接

package com.zq.jedis;

import redis.clients.jedis.Jedis;

public class JedisDemo1 {
    public static void main(String[] args) {
        Jedis jedis=new Jedis("这里填你的服务器ip地址",6379);
        #密码,requirepass里面设置的,这里填自己的密码
        jedis.auth("123456");
        String ping = jedis.ping();
        System.err.println(ping);
    }
}

运行结果:
