如何在centos7部署网站

1.买服务器

推荐阿里云试用三个月。

2.安装数据库，Java ，nginx

java安装教程 https://www.youtube.com/watch?v=90-0dRxs1fs&ab_channel=LiquidWeb
mysql安装教程 https://www.bilibili.com/video/BV1qS4y1h77S/
nginx安装 yum install nginx

其他注意事项：修改服务器的用户名和密码，修改数据库的账号密码，

mysql快速执行sql文件命令,前提：登录进入到mysql

mysql> source \home\user\Desktop\test.sql;
或 

3.上传前端代码

前端打包前⚠️

前端修改请求路径的ip为服务器ip,不能是localhost

打包命令

前端构建代码命令（假设用npm）：npm run build

打包后

会生成dist文件夹,将dist文件夹的内容上传到nginx的默认项目地址：/usr/share/nginx/html

⚠️注意：不用上传dist文件夹，否则请修改nginx配置文件的root 和index

4.打包及运行后端

后端打包前⚠️

后端需要修改yml的配置的数据库的用户名和密码为服务器的数据库的用户名和密码，等其他配置

打包

打包命令：mvn package

打包后

服务器运行命令：nohup java -jar 你的Jar包路径 &

运行后点击两次回车。

输出信息保存在文件nohup.out中，nohup.out在输入运行命令的路径中。

5.配置nginx

nginx配置文件路径：/etc/nginx/nginx.conf

修改前备份nginx.conf

以下是可供参考的配置

主要修改的地方为：

41行的server_name 填上自己的服务器的ip

53行的proxy_pass http://127.0.0.1:你的前端端口;

}

运行nginx

运行命令：systemctl start nginx

停止命令: systemctl start nginx

查看nginx状态： systemctl status nginx

开放端口

概念：

入方向：请求进入服务器的端口

出方向：执行查找

现在只配置入方向

建议开放：

前端端口

后端端口

80
