google voice 要绑定美国的手机号的，否则不能使用，淘宝所有卖 google voice 的都是骗子。

千万不要买 360，，，纯粹是广告机，各种给你下软件，返利广告更是多到恶心！

已开 Swap，谢谢所有大神！@all @Mac @Mazexal @agdhole @chinvo @falcon05 @jasonyang9 @jeffsun @lhy360121 @likuku @my3157 @stevenkang @salamanderMH

搞不懂我的硬盘还有多少。。。

@Mac myisam 完全没了解过，今天先看看情况，实在不行就试试 myisam，多谢了！

@my3157 我的云盘是 100G 的，不知道现在用了多少，应该不超过 50G，我的图片什么的都是阿里云 OSS 上，服务器上就网站备份比较占空间

@my3157 好 ，我把 innodb_buffer_pool_size 改成 256 了，要是还经常挂我就搞 8G 的 swap 试试。谢谢你！

又挂了。。。
Error establishing a database connection
This either means that the username and password information in your wp-config.php file is incorrect or we can ’ t contact the database server at 127.0.0.1. This could mean your host ’ s database server is down.

Are you sure you have the correct username and password?
Are you sure that you have typed the correct hostname?
Are you sure that the database server is running?
If you ’ re unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress Support Forums.

@likuku 淘宝同行竞争不过啊，人家都做 10 年了

@likuku 我研究研究吧 先去备份网站。。。问题是网站不赚钱啊。。。

@jeffsun @torment5524 @likuku @falcon05 我网站有 5 万多商品，每天流量两三千，IP1000 多。
@my3157 是的，只有一个盘
@likuku 买阿里云的 RDS 服务我 2 核 4G 的服务器一天要 24 块多，一年 8760，包年也要 5000 多，明显不划算啊。

@opengps 我不懂怎样把我的 MySQL 的数据库搞到阿里云上去。。。现在是 Wordpress 直接搞的

@likuku 改成了 512 再不行我就按这个设置 swap https://www.k2zone.cn/?p=1182

其实我不懂 innodb_buffer_pool_size 的大小具体有啥用，为什么要设置的小而不是大？

@torment5524 我前几天 innodb_buffer_pool_size 是 1g 也挂啊。。。

@chinvo 用 InnoDB 要开 swap
我不知道 InnoDB 在哪里，这是个什么东西

@torment5524 我看不懂日志，日志比较大。。。 我的网站是 Wordpress
