前言

大家好，我是老马。很高兴遇到你。

我们为 java 开发者实现了 java 版本的 nginx

https://github.com/houbb/nginx4j

如果你想知道 servlet 如何处理的，可以参考我的另一个项目：

环境说明

本地 windows 使用 WSL

安装预构建的 Ubuntu 包

NGINX 为以下 Ubuntu 操作系统提供包：

版本 代号 支持的平台
20.04 focal x86_64, aarch64/arm64, s390x
22.04 jammy x86_64, aarch64/arm64, s390x
22.10 kinetic x86_64, aarch64/arm64
23.04 lunar x86_64, aarch64/arm64

可以从以下位置安装该包：

  • 默认的 Ubuntu 存储库。这是最快的方法，但通常提供的包已过时。

  • nginx.org 上的官方存储库。第一次必须设置 apt-get 存储库，但之后提供的包始终是最新的。

从 Ubuntu 存储库安装预构建的 Ubuntu 包

  1. 更新 Ubuntu 存储库信息：
sudo apt-get update
  1. 安装包：
sudo apt-get install nginx
  1. 验证安装：
sudo nginx -v

日志如下：

nginx version: nginx/1.18.0 (Ubuntu)

直接访问

$ curl http://localhost

<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

常见操作命令

1. 查看状态

查看 Nginx 状态（检查是否正在运行）：

sudo systemctl status nginx

如下：

     Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)

2. 启停 nginx

启动 Nginx

sudo systemctl start nginx

可以状态确认：

$ sudo systemctl status nginx

$ sudo systemctl status nginx
● nginx.service - A high performance web server and a reverse proxy server
     Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
     Active: active (running) since Sat 2024-05-11 10:44:40 CST; 11s ago
       Docs: man:nginx(8)
    Process: 3631 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
    Process: 3632 ExecStart=/usr/sbin/nginx -g daemon on; master_process on; (code=exited, status=0/SUCCESS)
   Main PID: 3633 (nginx)
      Tasks: 17 (limit: 9362)
     Memory: 14.1M
     CGroup: /system.slice/nginx.service
     ...

停止 Nginx

sudo systemctl stop nginx

停止后查看状态：

$ sudo systemctl status nginx
○ nginx.service - A high performance web server and a reverse proxy server
     Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
     Active: inactive (dead) since Sat 2024-05-11 10:43:42 CST; 2s ago
       Docs: man:nginx(8)
    Process: 3396 ExecStop=/sbin/start-stop-daemon --quiet --stop --retry QUIT/5 --pidfile /run/nginx.pid (code=exited,>
   Main PID: 1645 (code=exited, status=0/SUCCESS)

May 11 10:38:03 d systemd[1]: Starting A high performance web server and a reverse proxy server...
May 11 10:38:03 d systemd[1]: Started A high performance web server and a reverse proxy server.
May 11 10:43:42 d systemd[1]: Stopping A high performance web server and a reverse proxy server...
May 11 10:43:42 d systemd[1]: nginx.service: Deactivated successfully.
May 11 10:43:42 d systemd[1]: Stopped A high performance web server and a reverse proxy server.

重启

个人理解：重启=关闭+启动

sudo systemctl restart nginx

启动时自动运行 nginx

作用：可以让 ngix 是否在机器重启后服务自动运行。

  1. 使 Nginx 在启动时自动运行：

    sudo systemctl enable nginx

  2. 禁止 Nginx 在启动时自动运行：

    sudo systemctl disable nginx
