CentOS下Fail2ban自动退出服务和字体渲染问题！

启动fail2ban具体报什么错误？
中文字体的渲染，用桌面？

关于字体渲染的问题：
主要是我的网站是在本地（Windows+IIS+PHP）调试的，但是上传到CentOS后，发觉网站的字体显示和Windows下有明显区别，我不知道这和CentOS的字体渲染是不是有关系，因为我觉得相同的代码为何在Windows和CentOS运行下会出现不同的显示效果。而且明显CentOS的现实效果比Windows差一些。
所以我的意思如果这个CentOS的字体渲染有关系那么肯定要修复这个问题，但是服务器肯定是需要运行桌面的。而且我虚拟机测试过，ubuntu server下同样的代码显示效果和Windows几乎相同的。我也查过资料，有人说Linux需要安装infinality这样的字体渲染包，我不知道infinality这样的字体渲染是否只是对Linux运行桌面的时候有用还是对服务器的现实都有用。

写错了，服务器肯定是不需要运行桌面

重启服务器导致内存中文件夹/var/run/fail2ban丢失，执行如下命令再启动试试：

sed -i 's@Starting fail2ban.*@&\n    [ ! -e "/var/run/fail2ban" ] \&\& mkdir /var/run/fail2ban@' /etc/init.d/fail2ban
systemctl daemon-reload
service fail2ban start
