Git命令获取源代码

[root@web-nginx ~]# yum install -y git
[root@web-nginx ~]# git clone https://gitee.com/hyunze/xzs-mysql.git

安装配置mysql

#安装MySQL，修改密码
[root@localhost ~]# yum -y install mysql-server
[root@localhost ~]# systemctl start mysqld
[root@localhost ~]# grep pass /var/log/mysqld.log

前端打包

#学生端
[root@web-nginx ~]# cd xzs-mysql/source/vue/xzs-student/
[root@web-nginx xzs-student]# npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/
[root@web-nginx xzs-student]# npm install --registry https://registry.npm.taobao.org  
[root@web-nginx xzs-student]# npm run build
[root@web-nginx xzs-student]# cp -r student xzs-mysql/source/xzs/src/main/resources/static#管理端
[root@web-nginx ~]# cd xzs-mysql/source/vue/xzs-admin/
[root@web-nginx xzs-admin]# npm config set sass_binary_site https://npm.taobao.org/mirrors/node-sass/
[root@web-nginx xzs-admin]# npm install --registry https://registry.npm.taobao.org  
[root@web-nginx xzs-admin]# npm run build
[root@web-nginx xzs-admin]# cp -r admin xzs-mysql/source/xzs/src/main/resources/static

打包jar包

[root@web-nginx ~]# cd xzs-mysql/source/xzs
[root@web-nginx xzs]# mvn package

服务上线

[root@web-nginx ~]# mkdir -p /application/java-server
[root@web-nginx ~]# cp xzs-mysql/source/xzs/target/xzs-3.9.0.jar /application/java-server
[root@web-nginx ~]# cd /application/java-server
[root@web-nginx java-server]# nohup java -Duser.timezone=Asia/Shanghai -jar -Dspring.profiles.active=prod  xzs-3.9.0.jar  > start1.log  2>&1 &

学生端访问地址为：http://ip:8000/student
管理员端访问地址为：http://ip:8000/admin
学生端默认账号：student / 123456
管理端默认账号：admin / 123456

!!!打jar包失败的解决方法

将国外的maven镜像切换为国内的镜像源
阿里云maven镜像源

[root@web-nginx ~]# vim  /usr/local/maven/conf/settings.xml

将配置文件中mirrors模块切换为阿里云镜像源如下图

修改完成后重新打包

[root@web-nginx ~]# cd xzs-mysql/source/xzs
[root@web-nginx xzs]# mvn package
