1. Install Apache

sudo apt-get install apache2

测试：浏览器访问 http://localhost   //会出现网页。

查看状态： service apache2 status/start/stop/restart
Web目录： /var/www
安装目录： /etc/apache2/
全局配置： /etc/apache2/apache2.conf
监听端口： /etc/apache2/ports.conf
虚拟主机： /etc/apache2/sites-enabled/000-default.conf

2, Install MySQL, skip it if installed. If it is not installed, click here to install mysql.

3. Install PHP

Check the local php version, run

php -v

to install the latest version of php, use the command

sudo apt-get install php

4. Install other modules

sudo apt-get install libapache2-mod-php
sudo apt-get install php7.0-mysql

Restart the service

service apache2 restart
service mysql restart

Test whether Apache can parse PHP

vim /var/www/html/phpinfo.php

文件代码为：<?php echo phpinfo();?>

浏览器访问：http://localhost/phpinfo.php  //会出现PHP Version网页，如果是云服务器，则将 localhost 改为你云服务器IP

5. Modify permissions

sudo chmod 777 /var /www

6. Install phpMyAdmin

sudo apt-get install phpmyadmin

During installation: (space to enter) select apache2, click Confirm (Enter).

If the following error occurs

sudo mv /var/lib/dpkg/info /var/lib/dpkg/info_old   //现将info文件夹更名
sudo mkdir /var/lib/dpkg/info     //再新建一个新的info文件夹
sudo apt-get update && apt-get -f install   //重新下载
sudo mv /var/lib/dpkg/info/* /var/lib/dpkg/info_old   //执行完上一步操作后会在新的info文件夹下生成一些文件，现将这些文件全部移到info_old文件夹下
sudo rm -rf /var/lib/dpkg/info  //把自己新建的info文件夹删掉
sudo mv /var/lib/dpkg/info_old  /var/lib/dpkg/info //把以前的info文件夹重新改

//测试
service php7.0-fpm restart  //注意版本
service apache2 restart

//测试
http://localhost/phpmyadmin  //远程侧修改 localhost

vim /etc/apache2/apache2.conf

末尾添加：

include /etc/phpmyadmin/apache.conf

AddType application/x-httpd-php .php .htm .html

AddDefaultCharset UTF-8

service apache2 restart
