前言
今天把在虚拟主机上面的wordpress博客转移到VPS上面了
因为域名是CC，无法备案，不能在国内。所以弄了香港的VPS。折腾了大半天
从升级虚拟主机，到换VPS
也因为实在是受不了网站加载 Waiting (TTFB) 加载速度了。点一个页面要2-5秒。
测速全红，记录下坑
系统：Linux debian 8.0
平台：Wordpress 4.9.0
插件:memcache，autoptmize
迁移后效果图
安装步骤
http://soft.vpser.net/lnmp/lnmp1.2-full.tar.gz && tar zxf lnmp1.2-full.tar.gz && cd lnmp1.2-full && ./install.sh lnmp
按上述命令执行后，会出现如下提示：
+------------------------------------------------------------------------+ | LNMP V1.2 for Ubuntu Linux Server, Written by Licess | +------------------------------------------------------------------------+ | A tool to auto-compile & install LNMP/LNMPA/LAMP on Linux | +------------------------------------------------------------------------+ | For more information please visit http://www.lnmp.org | +------------------------------------------------------------------------+ Please setup root password of MySQL.(Default password: root) Please enter: ---------------------
需要设置MySQL的root密码（不输入直接回车将会设置为root），输入后回车进入下一步，如下图所示：
Do you want to enable or disable the InnoDB Storage Engine? Default enable,Enter your choice [Y/n]:
这里需要确认是否启用MySQL InnoDB，如果不确定是否启用可以输入 y ，输入 y 表示启用，输入 n 表示不启用。默认为y 启用，输入后回车进入下一步，选择MySQL版本：
You have 5 options for your DataBase install. 1: Install MySQL 5.1.73 2: Install MySQL 5.5.42 (Default) 3: Install MySQL 5.6.23 4: Install MariaDB 5.5.42 5: Install MariaDB 10.0.17 Enter your choice (1, 2, 3, 4 or 5):
输入MySQL或MariaDB版本的序号，回车进入下一步，选择PHP版本：
You have 5 options for your PHP install. 1: Install PHP 5.2.17 2: Install PHP 5.3.29 3: Install PHP 5.4.41 (Default) 4: Install PHP 5.5.25 5: Install PHP 5.6.9 Enter your choice (1, 2, 3, 4 or 5):
输入PHP版本的序号，回车进入下一步，选择是否安装内存优化：
You have 3 options for your Memory Allocator install. 1: Don't install Memory Allocator. (Default) 2: Install Jemalloc 3: Install TCMalloc Enter your choice (1, 2 or 3):
可以选择不安装、Jemalloc或TCmalloc，输入对应序号回车。
如果是LNMPA或LAMP的话还需要设置管理员邮箱，再选择Apache版本
提示”Press any key to install…or Press Ctrl+c to cancel”后，按回车键确认开始安装。 LNMP脚本就会自动安装编译Nginx、MySQL、PHP、phpMyAdmin、Zend Optimizer这几个软件。

安装时间可能会几十分钟到几个小时不等，主要是机器的配置网速等原因会造成影响。
如果显示Nginx: OK，MySQL: OK，PHP: OK
并且Nginx、MySQL、PHP都是running，80和3306端口都存在，并Install lnmp V1.2 completed! enjoy it.的话，说明已经安装成功。
添加虚拟主机
执行：lnmp vhost add 出现如下界面：
root@host:~/lnmp1.2-full# lnmp vhost add

上面这部可能会出错。我这里提示MYSQL ROOT密码不对。
自己进入MYSQL在重置一下密码
mysql> use mysql;
delete from mysql.user where user='';//删除用户为空的用户，我这里出现了2个
mysql> update user set password=password('123') where user='root';
mysql> flush privileges;
安装完成后FTP没有安装上。
在lnmp目录下：./pureftpd.sh
按提示输入当前MySQL的root密码，输入完成，回车确认，会提示如下信息：
这一步是设置FTP用户管理后台的登陆密码。输入完成回车确认
因为PHP管理后台需要连接数据库，所以会在MySQL上创建一个ftp用户，这里设置的就是这个用户的密码。输入完成，回车确认。
回车 显示 “Press any key to start install Pure-FTPd…” 再次回车确认即可开始安装。
FTP添加用户
lnmp ftp add
Enter ftp account name:登陆FTP的账户
Enter password for ftp account vpser:FTP密码
Enter directory for ftp account vpser:FTP分配的目录(或者直接跟根目录)/home/wwwroot/
继续折腾
到这里基本可以打开网站了，数据库或者FTP，直接把WORDPRESS的数据上传到FTP
但是加载WORDPRESS慢的问题还是没有解决。各种百度,GOOGLE，貌似WORDPRESS就是这个了样子
不开缓存好像都好慢。那就继续折腾吧
因为我安装的LNMP1.2版本。也仅适用于LNMP1.2、1.3及1.4等以后的版本
进入lnmp解压后的目录，执行：./addons.sh install eaccelerator
可以根据自己的需求选择php-memcache或php-memcached扩展，
这里我输入对应的序号2，回车，再次确认回车开始安装。
wordpress配置
1,下载 object-cache.php 文件,解压后上传至 /wp-content 目录
https://github.com/tollmanz/wordpress-pecl-memcached-object-cache/blob/master/object-cache.php
2,编辑 wp-config.php 文件，添加如下代码：define(‘ENABLE_CACHE’, true);
3,batcache1.4:https://downloads.wordpress.org/plugin/batcache.1.4.zip
batcache.php传至 /wp-content/plugins 目录
advanced-cache.php传至 /wp-content 目录
var $max_age = 300; // 缓存有效时间 (0关闭) var $remote = 0; // Zero disables sending buffers to remote datacenters (req/sec is never sent) var $times = 2; // 几次访问开启缓存 (2个以上) var $seconds = 120; // 多久生效 (0马上生效)
4,在线监控：http://pecl.php.net/get/memcache-3.0.8.tgz
$MEMCACHE_SERVERS[] = '127.0.0.1:11211'; //改一个，后面一条屏蔽
卸载方法
执行：./addons.sh uninstall memcached
autoptmize
官方插件搜索，开启HTML，CSS即可。立马见效。
