Fail2ban无法在Centos 7上启动。缺少/ var / log / secure文件

几天前我买了vps并安装了Centos 7。现在我正在尝试为ssh设置fail2ban。我安装了epel-release。Iptables默认使用。当我尝试启动fail2ban时，这就是我得到的：

 Job for fail2ban.service failed because the control process exited with error code. See "systemctl status fail2ban.service" and "journalctl -xe" for details.

fail2ban启动的调试：

我试图重新安装iptables，但仍然在全新安装后我缺少安全日志文件。它可能是由vps提供商设置引起的？

为什么不创建丢失的文件？

touch /var/log/secure
chown root. /var/log/secure
chmod 0600 /var/log/secure

然后：

systemctl restart fail2ban.service

/var/log/secure来自rsyslog。确保您已authpriv.* /var/log/secure进入/etc/rsyslog.conf并rsyslog正在运行：

systemctl status rsyslog
