安装php的扩展库mcrypt、curl和gd库

1. apt-get install php5-mcrypt;
2. apt-get install php5-curl;
3. apt-get install php5-gd;

安装完成后，

重启apach服务即可：

sudo service apache2 restart

修改根目录： 
在 /etc/apache2/sites-available 中修改 000-default.conf 
中的DocumentRoot /var/www/ 修改为想要的目录 
比如：DocumentRoot /var/www/html/mainpage

接下来重启apache,sudo apache2ctl -k restart 即可

修改默认网页： 
修改/etc/apache2/mods-available/dir.conf中的内容 
原来是：

<IfModule mod_dir.c>
    DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm
</IfModule>

添加上想要的/wordpress就行啦~

<IfModule mod_dir.c>
    DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm /wordpress
</IfModule>
