底下紀錄如何在 Ubuntu 18.04 上建立 LAMP 的環境。
This note demonstrates how to create a LAMP environment on an Ubuntu 18.04 server.

步驟一：安裝 Apache Web Server (Step One: Installing apache web server)

Open a console and input the following commands to install apache.

接著查詢主機IP

You can find your server's public IP address by the following command:
ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'

在瀏覽器鍵入 local host ip。
Type the address in your web browser(Google chrome or firefox .etc).
http://server_domain_name_or_IP

若在瀏覽器上看到下圖，表示 apache已安裝成功。If you see the below message, your apache installation is completed.

可看到上圖時，apache便已經可跑靜態網頁了，預設的html檔案存放位置為 /var/www/html

步驟二：安裝MySql(Step Two: Installing mysql
Open a console and input the following commands to install mysql.

sudo apt-get install mysql-server

安裝完後輸入以下指令進行安全性設定
Type the following command to secure the MySQL installation:

sudo mysql_secure_installation

步驟三：安裝php與設定 php.ini(Step Three: Installing php and configuring the php.ini)

Installing php:

sudo apt-get install php-fpm php-mysql php libapache2-mod-php

Modifying dir.conf file:

sudo nano /etc/apache2/mods-enabled/dir.conf

From

DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm

To
DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm

Save and restart apache service:

sudo service apache2 restart

步驟四：建立php測試檔案(Step Five: Create a php file to test)

# Creating the test php file
sudo nano /var/www/html/info.php

Input the following php code into the new file(info.php).

<?php
phpinfo();

Open your browser to visit this page:
http://your_server_domain_or_IP/info.php

You should see some information about your server:
