## Install
```
sudo apt update && sudo apt install apache2
```
## 測試Apache
```
sudo service apache2 status
```
## 設置虛擬主機Virtual Hosts
假設要建立2個網站*test1.ui-code.com*與*test2.ui-code.com*
### 建立目錄並設置權限Permissions
```
sudo mkdir -p /var/www/test1.ui-code.com/public_html
sudo mkdir -p /var/www/test2.ui-code.com/public_html
sudo chmod -R 755 /var/www
```
### 建立測試頁面
#### 建立test1.ui-code.com的測試頁面
```
sudo nano /var/www/test1.ui-code.com/public_html/index.html
```
填入以下內容:
```html
<html>
<head>
<title>Welcome to test1.ui-code.com</title>
</head>
<body>
<h1>Welcome to test1.ui-code.com</h2>
</body>
</html>
```
#### 建立test2.ui-code.com的測試頁面
```
sudo nano /var/www/test2.ui-code.com/public_html/index.html
```
填入以下內容:
```html
<html>
<head>
<title>Welcome to test2.ui-code.com</title>
</head>
<body>
<h1>Welcome to test2.ui-code.com</h2>
</body>
</html>
```
### 建立虛擬主機文件Virtual Host Files
虛擬主機文件位於 /etc/apache2/sites-available/ 中,其用於告訴 Apache 網頁伺服器如何響應Respond 各種網域請求Request
讓我們為test1.ui-code.com 網域創建一個新的虛擬主機文件。
```
sudo nano /etc/apache2/sites-available/test1.ui-code.com.conf
```
將以下內容貼上:
```
<VirtualHost *:80>
ServerAdmin webmaster@test1.ui-code.com
ServerName test1.ui-code.com
ServerAlias www.test1.ui-code.com
DocumentRoot /var/www/test1.ui-code.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
```
再來為test2.ui-code.com 網域創建一個新的虛擬主機文件。
```
sudo nano /etc/apache2/sites-available/test2.ui-code.com.conf
```
將以下內容貼上:
```
<VirtualHost *:80>
ServerAdmin webmaster@test2.ui-code.com
ServerName test2.ui-code.com
ServerAlias www.test2.ui-code.com
DocumentRoot /var/www/test2.ui-code.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
```
### 啟用新的虛擬主機文件Virtual Host Files
現在我們有兩個虛擬主機文件,我們需要使用 a2ensite 工具來啟用它們。
```
sudo a2ensite test1.ui-code.com
sudo a2ensite test2.ui-code.com
```
測試配置語法是否有錯誤。
```
apachectl configtest
```
如果「Syntax OK」重啟 Apache。
```
sudo systemctl reload apache2
```
