在线教育网站项目第四步：deepseek骗我， WSL2不能创建两个独立的Ubuntu，但我们能实现实例互访及外部访问

一、说明

上一章折腾了半天，搞出不少问题，今天我们在deepseek的帮助下，完成多个独立ubuntu24.04实例的安装，并完成固定ip，实践证明，deepseek不靠谱，浪费我2个小时时间，我们将在下面实现，其实网上有很多信息比较旧

计划安装实例已经端口IP分配表

服务器配置表

服务器顺序	服务器名	IP地址	端口	主机名	说明
1	mysql	192.168.1.15	3306; ssh:2221	mysql	关系型数据库
2	redis		6379; ssh:2222		非关系型数据库
3	kkfileview		8012; ssh:2223	kkfileview	在线文件预览
4	elasticsearch		9200; ssh:2224	elasticsearch	搜索和数据分析模型
4	kibana		5601; ssh:2224	kibana	Kibana 是为Elasticsearch设计的开源分析和可视化平台
5	minio		服务端口：9000 控制台：9001 ; ssh:2225	minio	对象存储
6	nacos		注册中心：8848 控制台：9848 ; ssh:2226	nacos	动态服务发现、配置管理和服务管理平台
7	xxl-job-admin		8080; ssh:2227	xxl-job-admin	分布式任务调平台
8	seata		; ssh:2228	seata	分布式事务
9	roncoo-education-gateway		7700; ssh:2229	roncoo-education-gateway	在线教育网关服务
9	roncoo-education-system		7710; ssh:2229	roncoo-education-system	在线教育系统服务
9	roncoo-education-user		7720; ssh:2229	roncoo-education-user	在线教育用户服务
9	roncoo-education-course		7730; ssh:2229	roncoo-education-course	在线教育课程服务
一共9台服务器

推荐使用WSLMan 管理工具

Release v0.1.1.0 · jet2jet/WSLMan

二、安装Ubuntu-24.04

1、建立配置文件.wslconfig

在宿主机win11的登录用户目录下，建立文件.wslconfig，添加内容：

[experimental]
autoMemoryReclaim=gradual  
networkingMode=mirrored
dnsTunneling=true
firewall=true
autoProxy=true

[boot]
systemd=true

2、选择安装新的分发

3、选择ubuntu24.04 

4、安装

安装过程 

 安装完成

5、启动，添加用户密码

ip地址很有意思，192.168.1.15 是我主机的ip，也就是win11的地址，我们在上一篇文章中可不是这样的， 刚才我们建立的9台虚拟机ip地址都是一样，据说宿主机可以通过localhost访问所有的机器，这个就是添加了全局的.wslconfig有的效果，具体配置可以查资料，上面我们已经添加了

6、安装ssh

修改默认登录用户为x58win
sudo vi /etc/wsl.conf
添加内容
[user]
default=x58win
[boot]
systemd=true

 重启wsl

 

# 安装
sudo apt-get update
sudo apt-get install openssh-server##有错误，ssh.socket 是 systemd 的套接字单元，用于按需启动 SSH 服务（当有连接时启动）
Could not execute systemctl:  at /usr/bin/deb-systemd-invoke line 148.

sudo systemctl stop ssh.socket      # 停止套接字
sudo systemctl disable ssh.socket   # 禁用开机启动## 修改端口
sudo vi /etc/ssh/sshd_config
#Port 22 改为

sudo systemctl status ssh
sudo systemctl enable ssh

 好，OK，搞了不少时间，那个ssh.socket的错误，在ubuntu 22上直接显示是这个错误，而ubuntu24上没有指名，ssh是必须安装的所以我们先装了

7、安装docker和docker-compose

按照前面的文章安装就行

在线教育网站项目第二步 ：学习Vue3 + Nuxt3+springcloud，服务器为ubuntu24.04-CSDN博客https://blog.csdn.net/jiangkp/article/details/145995259

8、导出发行版

先expert出来，然后再import

选个目录，如果启动了，需要shutdown WSL 

点击ok开始expert ，abort是停止运行

 最后变为close，直接关闭即可

9、注销Ubuntu-24.04

注销掉就都没了，可以回去看看那个appdata目录下的东西都没有

原来安装的发行版没有了 

目录下了也没有东西了

二、安装9台的服务器

mysql
redis
kkfileview
elasticsearch
minio
nacos
xxl-job-admin
seata
roncoo-education

选择上面导出的虚拟机，分发名字自己要安装虚拟机名字，自己要安装的地址

 开始安装

 完成

  

 下面再建立8个，完全为了测试

三、配置各个实例

1、进入实例

先选下用户

比方说进入redis，看下面

2、查点想查的东西 

x58win@x58:~$ docker --version
Docker version 28.0.1, build 068a01e
x58win@x58:~$ docker-compose --version
Docker Compose version v2.33.1
x58win@x58:~$ sudo systemctl status ssh
[sudo] password for x58win:

             └─214 "sshd: /usr/sbin/sshd -D [listener] 0 of 10-100 startups"

Mar 19 19:16:44 x58 systemd[1]: Started ssh.service - OpenBSD Secure Shell server.

3、修改主机名

sudo vi /etc/wsl.conf[network]
hostname = mysql  # 替换为你想要的主机名
generateHosts = false           # 阻止 WSL 自动生成 hosts 文件

更新 /etc/hosts 添加互相解析

sudo vi /etc/hosts

将x58 改为mysql

4、修改ssh端口

sudo sed -i 's/Port 2220/Port 2221/' /etc/ssh/sshd_config对应端口在这里，22开头的就是ssh地址
"mysql8" = 2221,3306
"redis" = 2222,6379
"kkfileview" = 2223,8012
"elasticsearch" = 2224,9200,5601
"minio" = 2225,9000,9001
"nacos" = 2226,8848,9848
"xxl-job-admin" = 2227,8080
"seata" = 2228,8091
"roncoo-education" = 2229,7700,7710,7720,7730

重启

5、每个ubuntu24.04实例都要来一遍 

四、配置Windows防火墙和端口转发

创建脚本 MakeWslPort.ps1

# powershell.exe -ExecutionPolicy Bypass -File "D:\wsl\Script\MakeWslPort.ps1"# 脚本功能：为WSL实例分配固定IP并配置端口转发
$wslInstances = @("mysql", "redis","kkfileview","elasticsearch","minio","nacos","xxl-job-admin","seata","roncoo-education")
