shadowsocks-libev不支持单配置文件中指定不同端口及密码的多用户配置。

需要新建不同的配置文件，通过下面命令启动：

setsid ss-server -c (path to config file) -u

Debian9中，官方不再支持denyhosts，理由是安全及上游不再更新等。
替换选项是fail2ban。

参考文档：
https://www.vultr.com/docs/how-to-setup-fail2ban-on-debian-9-stretch

1. Debian9中mysql自动变成了mariadb，mariadb的配置方式与mysql稍有不同，参考下面文档
   https://www.digitalocean.com/community/tutorials/how-to-install-mariadb-on-debian-9
2. Debian9中php7.0不带utf8.decode()，typecho会出错，需要安装php7.0-xml

之前加入下面代码

<meta http-equiv="refresh" content="0.2;url=目标地址">

一般的出现这种情况时,nginx.conf里的的location设置都是类似这样

location ~ .*\.php$

要支持pathinfo，要改成

location ~ .*\.php(\/.*)*$

在某些老版本的php里面，可能还要打开php.ini里的cgi.fix_pathinfo

cgi.fix_pathinfo = 1

注意：自动安装的php版本是7.2，nginx的默认配置文件中php是7.0，需要手工编辑一下。
