自己的网站很久没有去上了，想打开发现居然打不开了，所以就找了一系列的原因。

vps不行了 dns解析出问题了域名出问题了

简单排查之后，我的vps服务商用的是搬瓦工(bandwagonhost) ,重启了一下还是无法访问，后来我又看了一下我用的域名托管(dnspod),好像也是没有问题的。最后又查了一下域名提供(freenom)，域名到期还有一年，应该也没有问题。

后来又看了一会，才想到会不会是apache服务器没有启动
重启了一下：sudo apache2ctl -k restart
可以访问了[被自己蠢哭了

但是mysql还是无法使用。
于是试了一下重启: service mysql start
报错说无法启动，也没有写什么原因(服务器上的ubuntu系统比较小，错误提示不全)，找了半天也不知道什么问题。

后来上网找资料才知道看错误日志(在/var/log/mysql中)，里面写了出错原因是[ERROR] /usr/sbin/mysqld: unknown variable ‘default-character-set=utf8’

后来网上查了之后才发现要把mysql配置文件my.cnf中的default-character-set=utf8改为character_set_server=utf8就可以了，试了一下果然可以了==
(my.cnf 在/etc/mysql 中)
真弱==
