find / -name my.cnf

全新安装：apt-get install vsftpd

命令如下：zip -r %%.zip ./

建立表：

CREATE TABLE IF NOT EXISTS `postdata` ( `id` int(11) NOT NULL auto_increment, `city` varchar(255), `time` varchar(255), `code` varchar(255), `school` varchar(255), `pay` varchar(255), `state` varchar(255), `updatetime` datetime PRIMARY KEY (`code`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

joomla上安装sobipro时，需要curl库的扩展支持，安装命令如下：

sudo apt-get install curl libcurl3 libcurl3-dev php5-curl

I’ve been using Linode for a few months to host about a dozen websites and I’ve been very happy with the experience. I have found the documentation at Linode to be clear and concise, especially when it comes to setting up multiple sites using a standard, Ubuntu-based LAMP (Linux, Apache, MySQL, PHP) configuration.
