在现代的Web开发中，Vue.js已经成为一种非常流行的JavaScript框架。为了更高效地管理和部署Vue.js项目，使用自动化构建工具是至关重要的。Jenkins作为一款强大的持续集成和持续部署（CI/CD）工具，为我们提供了一种便捷的方式来自动化构建Vue.js项目。本文将介绍如何在Jenkins中配置和使用自动化构建Vue.js项目的步骤。

1、安装Jenkins 

前面已经讲过使用docker安装Jenkins ，可以参考前面的文章 ：Vagrant + docker搭建Jenkins 部署环境-CSDN博客

2、安装nodejs

在容器里面安装nodejs,根据项目来下载所需要的版本，我这里下载的是node-v10.24.1-linux-x64.tar.xz

解压后，设置环境变量：vim /etc/profile

 保存后，让文件生效：

source /etc/profile

查看环境变量：

 看到node环境已经安装完成，这里要说一下，node编译需要python环境，所以我们也要提前安装好python环境，这里不做介绍了。

另外Jenkens 需要安装插件：Publish Over SSH ,  NodeJS Plugin

3、安装nginx ，这是是需要在宿主机上面安装，因为我的jenkins和服务器不在一台机器上。

 接着我们看看是否安装成功：

接下来我们先把nginx配置好，代码目录在 /htdocs/workspace下面：

nginx配置的文件内容如下：

<code>server {

listen 80;

server_name hg.vue.com;

gzip on;

gzip_buffers 32 4K;

gzip_comp_level 6;

gzip_min_length 100;

gzip_types application/javascript text/css text/xml text/plain application/x-javascript image/jpeg image/gif image/png;

gzip_disable "MSIE [1-6]\.";

gzip_vary on;

#charset koi8-r;

#access_log /var/log/nginx/portal.access.log main;

access_log /var/log/nginx/portal.access.log;

location / {

root /htdocs/workspace/dist;

try_files $uri $uri/ /index.html;

index index.html index.htm;

}

location /api/ {

proxy_set_header Host $http_host;

proxy_set_header X-Real-Ip $remote_addr;

proxy_set_header REMOTE-HOST $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_pass http://127.0.0.1:8080/;

}

}

 4.配置vue项目的打包编译的自动化配置。

我这里有一个大数据项目：

5 。接着来配置jenkins自动化构建设置。

 在全局设置里面找到 Publish over SSH，填写下面的配置：

 Path to key 就是容器的秘钥：

这里我们测试一下连接宿主机，可以看到连接成功！

 创建一个自由分格的前端项目，点击保存：

 配置git访问的仓库路径和秘钥，前面那篇文章已经讲过怎么配置凭证，这里就不细说了。

配置代码推送时候触发自动构建。

 生成gitlab访问的api token

配置node js版本，这里也可以通过界面自动安装所需要的版本。

 在项目里面设置第三方访问的webhook ,把前面jenkins生成的api token和地址填入下面的位置后保存。

 接下来测试一下能否正常访问：

 设置构建shell 脚本：

 脚本如下：

<code>#加载依赖

node -v

cd /var/jenkins_home/workspace/element

npm install node-sass --unsafe-perm=true

#构建程序

npm run build:prod

#移除之前的压缩包

rm -rf dist.tar.gz

#把当前目录的所有文件打包成dist.tar.gz

tar zcvf dist.tar.gz dist

exit 0

 配置完成后，提交代码：

 可以看到已经开始自动化构建了：

 在容器里面看到已经打包成功：

 可以看到宿主机的代码已经上传过来了。
