无法启动 Fail2Ban

最近我收到 3 封来自 Fail2Ban 的电子邮件

  • 监狱 nginx-http-auth 已被停止。
  • 监狱 nginx-badbots 已被停止。
  • 监狱 ssh 已停止。

然后我启动 SSH 进入我的虚拟机，这是日志

└── tail -f /var/log/fail2ban.log

2019-09-17 21:07:06,335 fail2ban.jail   : INFO   Jail 'ssh' stopped

然后我试着停下来再开始

service fail2ban stop
service fail2ban start

我不断得到

└── service fail2ban stop

└── service fail2ban start

我该如何进一步解决这个问题？

答案1

尝试使用fail2ban-client reload然后重新启动您的服务。
