nginx&ubuntu 安装使用

部署环境：Ubuntu 22.04 LTS (GNU/Linux 5.15.0-94-generic x86_64)

1.安装

sudo apt-get install nginx # 默认配制放在 /etc/nginx/sites-enabled/default

2. 常用指令

sudo systemctl enable nginx.service # 开机自启动
sudo systemctl start nginx.service
sudo systemctl status nginx.service
sudo systemctl stop nginx.service
sudo systemctl restart nginx.service
sudo journalctl -fu nginx.service # 查看运行日志

sudo nginx -t # 查看nginx配制是否生效
sudo nginx -s stop | quit | reopen | reload # 常用指令

3. 配制代理

• 前端
• 后端：网关，单体应用
• 直接上配制

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name _;

    location ^~ /gateway/ {
        proxy_pass http://localhost:20000/gateway/;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $remote_addr;
    }

    location ^~ /oss/ {
        proxy_pass http://localhost:20011/;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $remote_addr;
    }

    location ^~ /ws/ {
        proxy_pass http://localhost:20011/;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $remote_addr;
        proxy_http_version 1.1;  # 必须设置为1.1以支持WebSocket
        proxy_set_header Upgrade $http_upgrade;  # 设置Upgrade头
        proxy_set_header Connection "upgrade";   # 设置Connection头
    }

    location / {  # Vue应用的访问路径; 如果需要配制前缀,例如 /web，需要在Vue应用打包时指定前缀，这样才能反向代理成功
        root /home/ubuntu/web/dist;
        index index.html index.htm;
        try_files $uri $uri/ /index.html =404;
    }
}
