华为云L实例云服务器部署前后端分离项目全过程记录

1、配置云服务器

2、上传前端项目并配置nginx

首先在前端项目运行以下代码将项目打包
我遇到node.js和openssl两个版本不兼容问题，更新版本依次解决即可

vue-cli-service build

看一下package.json文件里脚本配置里面对应的命令，运行那个

一般会把项目整个打包到dist文件里，然后上传dist文件即可

}Node.js v18.13.0

安装 EPEL（Extra Packages for Enterprise Linux）存储库:

sudo yum install epel-release

安装 Nginx：

sudo yum install nginx

启动并启用 Nginx：

sudo systemctl start nginx
sudo systemctl enable nginx

上传dist文件到服务器指定目录

scp -r ./dist/* username@your_server_ip:/var/ww/myapp

编辑 Nginx 配置文件以指向你的应用目录：

sudo vi /etc/nginx/conf.d/myapp.conf

在配置文件中添加以下内容：

server {listen       80;server_name  your_domain_or_ip;//只需要将your_domain_or_ip改成服务器域名或者公网ip即可location / {root   /var/www/myapp;index  index.html;try_files $uri $uri/ /index.html;}# 转发后端请求到 Tomcatlocation /backend/ {proxy_pass http://localhost:8080/;proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}# Serve gzipped files if availablegzip_static on;gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;gzip_proxied any;gzip_comp_level 6;gzip_buffers 16 8k;gzip_http_version 1.1;gzip_min_length 256;
}

测试 Nginx 配置文件的正确性：

sudo nginx -t

如果配置文件测试通过，重启 Nginx：

sudo systemctl restart nginx

确保防火墙允许 HTTP 流量：

sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

在浏览器中访问你的域名或服务器 IP，确保你的前端应用已经成功部署。
然后就可以通过http：//your_eip访问你的前端页面了

3、下载jdk，tomcat、maven，mysql，打包后端项目，创建新数据库，上传后端项目并复制到tomcat目录下

下载jdk

sudo dnf install java-1.8.0-openjdk-devel

验证

java -version

使用 wget 命令下载 Tomcat 9.0.89：（需要到官网查看最新版本，替换里面的版本号）

cd /tmp
wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.89/bin/apache-tomcat-9.0.89.tar.gz

将下载的压缩包解压到你想安装的目录，例如 /opt/tomcat：

sudo mkdir /opt/tomcat
sudo tar xvf apache-tomcat-9.0.89.tar.gz -C /opt/tomcat --strip-components=1

验证

sudo systemctl status tomcat

在浏览器中打开 http://:8080，如果看到 Tomcat 欢迎页面，说明 Tomcat 已成功安装并运行。

下载maven

如果遇到yum的问题看如下文章解决

https://blog.csdn.net/modaoshi51991/article/details/139606895

打包java后端项目

使用 cd 命令切换到你的项目目录。

cd C:\D\USERPROG\rear\RuoYi-Vue

运行 Maven 构建命令：

mvn clean package

下载mysql
如果遇到问题参考我的这篇文章

https://blog.csdn.net/modaoshi51991/article/details/139725384?csdn_share_tail=%7B%22type%22%3A%22blog%22%2C%22rType%22%3A%22article%22%2C%22rId%22%3A%22139725384%22%2C%22source%22%3A%22modaoshi51991%22%7D

安装 MySQL：

sudo yum install mysql-community-server -y

启动 MySQL 服务：

sudo systemctl start mysqld

设置 MySQL 开机自启动：

sudo systemctl enable mysqld

获取 MySQL 临时 root 密码：

sudo grep 'temporary password' /var/log/mysqld.log

运行 MySQL 安全安装向导：

sudo mysql_secure_installation

运行这个命令后，系统会提示你输入临时 root 密码，然后进行一些安全配置：

Enter password for user root: 输入临时密码 dw)<Zk*rs1b+
New password: 设置一个新的 root 密码
Re-enter new password: 再次输入新密码以确认
Do you wish to continue with the password provided? (Press y|Y for Yes, any other key for No): 输入 Y
Remove anonymous users? (Press y|Y for Yes, any other key for No): 输入 Y
Disallow root login remotely? (Press y|Y for Yes, any other key for No): 输入 Y
Remove test database and access to it? (Press y|Y for Yes, any other key for No): 输入 Y
Reload privilege tables now? (Press y|Y for Yes, any other key for No): 输入 Y
