debian8/ubuntu14安装PHP环境一条命令，两分钟不到安装完毕

apt-get install apache2 libapache2-mod-php5 php5 php5-gd php5-mysql php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl mysql-server mysql-client

MySQL安全配置：

mysql_secure_installation

安装phpmyadmin管理工具

apt-get install phpmyadmin

CentOS/Debian9/Ubuntu16/FreeBSD也都差不多

绑个域名就这么简单 /etc/apache2/sites-available/

<VirtualHost *:80>
        ServerName XXX.com
        ServerAlias www.XXX.com
        ServerAdmin abs@live.com
        DocumentRoot /var/www/html/XXX
</VirtualHost>
