OB2D主機架設

8. 安裝Nginx（非必須）

安裝
```
apt install nginx
```
觀看狀態
```
systemctl status nginx
```

若有 nginx.service: Failed to parse PID from file /run/nginx.pid: Invalid argument 的錯誤

mkdir /etc/systemd/system/nginx.service.d
printf "[Service]\nExecStartPost=/bin/sleep 0.1\n" > /etc/systemd/system/nginx.service.d/override.conf
systemctl daemon-reload
systemctl restart nginx

手動啟動
```
systemctl start nginx
```
自動啟動
```
systemctl enable nginx
```
查看版本
```
nginx -v
```
檢查設定是否正確
```
nginx -t
```
在網頁目錄建立預設網頁：
```
vi /var/www/html/index.html
```

index.html的內容為

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
