bat文件启动nacos

最近接受的项目是使用Java开发的，开发过程中需要用到nacos，但是我不熟悉Java环境，也不熟悉nacos。
所以每次电脑开关机，都需要运行nacos，然后我就需要去找nacos的安装路径，然后找到bin文件，使用”startup.cmd -m standalone”命令运行启动，觉得很麻烦，于是便想着用bat文件运行，说干就敢。

但是我高估了现在的AI，当我有这个想法去问AI的时候，chatGPT4o还没有发布，所以我当时问了chatGPT3.5，然后......

首先是第一版：

@echo off
set NACOS_HOME=D:\Software\nacos

cd /d %NACOS_HOME%\bin
call startup.cmd

这个可以启动，但是命令行弹出框很快就结束了，也就是nacos只启动了一段时间，并没有长久运行，于是ChatGPT给了第二版：

@echo off
set NACOS_HOME=D:\Software\nacos

cd /d %NACOS_HOME%\bin
call startup.cmd
pause

这一版的结果是，运行一段时间后，显示按任意键继续，那也就是和第一版一样，也只运行的一段实际，继续问ChatGPT，给出了第三版：

@echo off
set NACOS_HOME=D:\Software\nacos

cd /d %NACOS_HOME%\bin
start cmd /k call startup.cmd

这一版的缺陷是运行了命令行弹出框，但是很快就被杀掉了，导致nacos还是没有启动起来，然后是第四版

@echo off
set NACOS_HOME=D:\Software\nacos

cd /d %NACOS_HOME%\bin
start /b call startup.cmd

这一版有一个验证缺陷，导致nacos运行的时候直接报错

命令行

ChatGPT提示这个是DNS的错误
这个日志显示了启动 Nacos 时遇到的错误信息：

Nacos 在启动过程中无法启动嵌入式的 Tomcat 服务器。
引发了 ApplicationContextException 异常，其中包含了启动 Tomcat 失败的详细信息。
错误日志中提到了 java.net.UnknownHostException: jmenv.tbsite.net，这可能是 DNS 解析失败导致的问题。

根据错误日志，似乎是因为 Nacos 试图连接某个地址导致的问题。你可以尝试解决以下问题：

网络连接问题：确保你的网络连接正常，且能够正确解析 jmenv.tbsite.net 这个地址。你可以尝试在浏览器中访问该地址，以验证网络连接是否正常。
防火墙或代理问题：检查是否有防火墙或代理导致了连接问题。有时候，防火墙或代理可能会阻止程序连接到特定的地址或端口。
DNS 解析问题：尝试在命令行中使用 nslookup jmenv.tbsite.net 命令来检查 DNS 解析是否正常。如果 DNS 解析失败，可能是你的 DNS 配置有问题，你可以尝试更换 DNS 服务器或手动配置 DNS 解析。

然后接下来几版都是围绕解决DNS的，终于在一次次的错误回答中，我失去了耐心，于是我选择上网查找。

终于，我在CSDN上找到了答案：

原文链接：bat 脚本执行cmd命令。（启动nacos）

一个非常简单的命令

start cmd /k "cd /d D:\Software\nacos\bin && startup.cmd -m standalone"

至于命令详解，在CSDN上的文章有解释，想了解的可以去原文查看。

二编

原本的是在Windows 10上面运行的，但是我换了一台Windows 11的电脑发现根本跑不通，就找不到文件路径，测试了一下，才发现Windows 11与Windows 10的进入文件夹的命令不一致，所以稍微修改了一下，适用于Windows 11。

然后想着，既然nacos也可以运行起来，那就写一个打包的文件吧，但是两个bat文件不太好，所以就合成一个文件吧

@echo off
chcp 936
echo 请选择要执行的操作：
echo 1: 运行nacos
echo 2: 打包程序
echo 输入其他数字退出

set /p userinput=请输入您的选择：

if "%userinput%"=="1" (
    start cmd /k "E: && cd E:\Software\nacos\bin && startup.cmd -m standalone" REM Win11
	REM start cmd /k "cd /e E:\Software\nacos\bin && startup.cmd -m standalone" REM Win10
) else if "%userinput%"=="2" (
    start cmd /k "E: && cd E:\Code\zzjz\HaoMianYuan\HMY_Matrix_J_RD\code && mvn clean package -Dmaven.test.skip=true" REM Win11
	REM start cmd /k "cd /e E:\Code\zzjz\HaoMianYuan\HMY_Matrix_J_RD\code && mvn clean package -Dmaven.test.skip=true" REM WIn10
) else (
    echo 您已选择退出。
)

echo 操作完成。
pause

打开bat文件，输入数字，1是运行nacos，2是打包文件，其他数字退出。

运行的时候如果报错，可以把REM后面的文件删除，仅保留需要执行的文件。

例如：

@echo off
chcp 936
echo 请选择要执行的操作：
echo 1: 运行nacos
echo 2: 打包程序
echo 输入其他数字退出

set /p userinput=请输入您的选择：

if "%userinput%"=="1" (
    start cmd /k "E: && cd E:\Software\nacos\bin && startup.cmd -m standalone" 
) else if "%userinput%"=="2" (
    start cmd /k "E: && cd E:\Code\zzjz\HaoMianYuan\HMY_Matrix_J_RD-1\code && mvn clean package -Dmaven.test.skip=true" 
) else (
    echo 您已选择退出。
)

echo 操作完成。
pause
