获取代码

[root@java ~]# yum install -y git
[root@java ~]# git clone https://gitee.com/y_project/RuoYi-Vue.git
[root@java ~]# ls
anaconda-ks.cfg                node-v12.18.4-linux-x64.tar.xz
apache-maven-3.9.5-bin.tar.gz  RuoYi-Vue
jdk-8u211-linux-x64.tar.gz

前端代码打包

[root@java ~]# cd RuoYi-Vue/ruoyi-ui
#替换为国内的taobaoyuan
[root@java ruoyi-ui]# npm install --unsafe-perm --registry=https://registry.npm.taobao.org
[root@java ruoyi-ui]# npm run build:prod
​
构建打包成功之后，会在根目录生成 dist 文件夹，里面就是构建打包好的文件，通常是 xxx.js 、xxx.css、index.html 等静态文件。
​
通常情况下 dist 文件夹的静态文件发布到你的 nginx 或者静态服务器即可，其中的 index.html 是后台服务的入口页面。
[root@java ruoyi-ui]# ls
babel.config.js  dist          package-lock.json  src
bin              node_modules  public             vue.config.js
build            package.json  README.md
[root@java ruoyi-ui]# cd dist/
[root@java dist]# ls
favicon.ico  html  index.html  index.html.gz  robots.txt  static
​
# 将静态资源移动到其他位置，然后进行后端代码打包
[root@java dist]# cd /root/RuoYi-Vue
[root@java RuoYi-Vue]# mv ruoyi-ui/ /opt/

正式上线

## 开始正式上线
[root@java target]# nohup java -jar -server -Xmx1024m -Xms1024m ruoyi-admin.jar &

## 如果报错链接不上数据库，且数据库配置无问题，将RuoYi-Vue/ruoyi-admin/src/main/resources/application-druid.yml文件中，
master:
                url: jdbc:mysql://10.36.192.253:3306/ruoyi?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8
                
将url中useSSL=yes改成useSSL=false，然后重新打包上线
​
在JDBC连接MySQL数据库时，useSSL参数用于指定是否使用SSL（安全套接层）加密连接。SSL是一种用于在计算机网络上提供安全通信的协议，它可以确保在客户端和服务器之间传输的数据在传输过程中是加密的，从而提供了一定程度的安全性。
​
当useSSL参数设置为false时，表示不使用SSL加密连接。这通常在开发和测试环境中比较常见，因为在这些环境下，对数据传输的安全性要求可能较低，而且SSL加密会增加一些额外的性能开销。在这种情况下，如果数据库服务器不要求强制的SSL连接，你可以将useSSL参数设置为false来简化连接配置。
​
但是，在生产环境中，特别是涉及到敏感数据的应用，强烈建议使用SSL加密来保护数据的传输安全性。在生产环境中，通常会将useSSL参数设置为true，以确保数据库连接是安全的。
​
在你的连接字符串中，useSSL=false表示不使用SSL加密连接。如果你的数据库服务器要求SSL连接，那么你需要将useSSL参数设置为true，以便建立加密连接。
