ProFTPd服务自动关闭

Question

我在运行UbuntuLinux14.04的服务器上安装了ProFTPd服务。我不知道为什么ProFTPd会自动关闭。我有足够的内存和CPU，我真的不知道为什么会这样。我还检查了ProFTPd配置文件，我仍然没有弄清楚。

我有什么办法阻止它自己关闭吗？

谢谢。

Answer 1

禤浩焯的回答是什么帮助我找到了我所需要的，但更详细地说，我所做的一切完全奏效了。

对我来说，关键是我将monit作为一个解决方案来安装，它可以监视proftpd进程，并确保它在任何时候都在运行，如果它检测到服务没有运行，那么它就会启动它。

First

确保先更新和升级

apt-get update
apt-get upgrade

第二

下载和安装莫尼特

apt-get install monit

第三代

cd /etc/monit/
vi monitrc

找到注释行set httpd port 2812 and并取消注释/更改为

set httpd port 2812

如果您希望能够访问它，而不是仅从本地主机，而是远程访问，请删除“和”。

那么只有取消注释行

allow admin:monit

这是您登录所需的用户身份验证凭据，根据您的需要更改它们。

然后将这个添加到文件中，我在页面底部添加了我的。更改您的端口号以匹配您的端口号，否则默认为21。

check process proftpd with pidfile /var/run/proftpd.pid
start program = "/etc/init.d/proftpd start"
stop program  = "/etc/init.d/proftpd stop"
if failed port 21 protocol ftp then restart

然后重新启动服务

/etc/init.d/monit restart

你完了然后..。欢迎你！这是一张很好的照片，让你看看它是什么样子

您可以从youripordomain.com:2812访问web接口。

Monit将不断检查服务，如果不运行，将启动它。您想要检查的任何服务都有很好的工具。

边注

如果您在monit中启动了接收状态“不存在”，那么请检查proftpd的PID文件中的proftpd PID是否匹配。

首先，确保proftpd正在运行/etc/init.d/proftpd start。

然后在终端中键入top并查找当前正在运行的proftpd的PID。

转到/var/run/proftpd.PID，确保该文件中的PID与top中的PID匹配。如果没有，则在文件中更改它并重新启动monit。

/etc/init.d/monit restart

Answer 2

我找到了解决办法。

不知道这是不是最好的，但它对我有用。

我为proftpd服务设置了一个监视器，如果检测到proftps为off，我将调用proftpd启动命令，仅此而已。

希望这能有所帮助。
