安装WordPress
下载并解压WordPress文件：
apt-get install unzip cd /home/64mb/web wget http://cn.wordpress.org/latest-zh_CN.zip unzip *.zip mv wordpress/* ./ rm -rf *.zip wordpress
让WordPress支持SQLite数据库，插件SQLite Integration：
cd /home/64mb/web wget https://downloads.wordpress.org/plugin/sqlite-integration.1.8.1.zip unzip *.zip mv sqlite-integration wp-content/plugins cp wp-content/plugins/sqlite-integration/db.php wp-content rm *.zip
修改WordPress配置文件：
cp wp-config-sample.php wp-config.php vi wp-config.php
把下面几行注释或删除掉：
define('DB_NAME', 'database_name_here');
define('DB_USER', 'username_here');
define('DB_PASSWORD', 'password_here');
define('DB_HOST', 'localhost');替换或添加上：
define('DB_FILE', '64mb');
define('DB_DIR', '/home/64mb/db');重置站点目录、数据库目录用户和用户组：
chown -R www-data.www-data /home/64mb
浏览器中打开域名，填写博客名称等信息安装就可以了。
安装之后有下面的提示，无视之（默认已经在虚拟主机配置文件中做了安全配置）：
Your webserver doesn't seem to be Apache. So the database directory access restriction by the .htaccess file may not function. We strongly recommend that you should restrict the access to the directory /home/64mb/db/ in some other way.
END..
不出意外你的WordPress程序就已经运行在128MB内存的VPS上了！
