我需要清除 logstash，但是当我尝试运行 apt purge logstash 时出现错误：

root@vmi503579:~# apt purge logstash
^Citing for cache lock: Could not get lock /var/lib/dpkg/lock. It is held by process 2797938 (dpkg)... 20s

所以我试图找到导致这个的pid 2797938

root@vmi503579:~# ps -x | grep 2797938
2797938 ?        Ss     0:00 /usr/bin/dpkg --status-fd 57 --no-triggers --force-depends --abort-after=1 --remove logstash:amd64

这是我之前尝试停止 logstash 的尝试。所以我尝试杀死进程 2797938 并再次运行 purge logstash。没有成功。然后我尝试用关键字logstash杀死所有进程。然后尝试再次运行 apt purge logstash

root@vmi503579:~# apt purge logstash
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

现在我真的迷路了。我应该怎么做才能修复它？谢谢你的帮助。

我想知道 Ubuntu 是否有类似的事件。我需要运行 Jenkins 的工作，但 Jenkins 没有 sudo 权限，我不想给他。但是作业需要运行一些需要 sudo 权限的操作。解决方案可能是触发一个以 root 用户身份侦听的事件，该事件将以 sudo 权限运行代码。可能我仍然对特权感到困惑，但我认为这可能非常方便。或类似公共 root 用户界面的东西，它可供其他用户使用，但将以 root 用户身份运行。喜欢

root->doSomethingAsRoot()

希望你明白我想要达到的目标。感谢帮助。

PS这个问题与这个问题有关

我在 Ubuntu 20.04 上有一个邮件服务器。昨天我设置了 UFW 防火墙，它看起来像：

今天我收到一封包含此日志的电子邮件，其中显示了数百次以 root 身份登录的尝试：

我不确定，但我在某处读到 UFW 能够在 30 秒窗口内阻止来自一个 IP 的失败登录次数。我不知道，但在日志中确实有数百次尝试。或者是防火墙还没有设置时的日志？我大约 12 小时前设置的。我的防火墙对吗？非常感谢您的帮助。

我有一个运行 bash.sh 文件的 cron 作业。如果我在终端中运行文件，它工作正常。但是当我尝试将它作为 cron 作业运行时，那里发生了一些事情，我不知道是什么。Cron 作业看起来像：

*/5 * * * * bash /home/vlado/custom-scripts/selenium-server/run-selenium-hub-and-nodes.sh 2>> /var/log/cron/selenium-server.log

和 run-selenium-hub-and-nodes.sh 在这里

#!/bin/bash

cd /opt/selenium-server/

# -c returns number of lines in grep result
countHub=$(ps -x | grep -v "grep" | grep "selenium-server" | grep "role hub" -c)
countNodes=$(ps -x | grep -v "grep" | grep "selenium-server" | grep "role node" -c) 


# if selenium server HUB is in ps -x result
if [ $countHub -eq 1 ] 
then 


  # if there is NO NODE
  if [ $countNodes -eq 0 ] 
  then 
    
    # start two new nodes
    java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://173.249.58.30:4444/grid/register/ & 
    java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://173.249.58.30:4444/grid/register/ & 
    exit 0    
  
  # if there is only ONE NODE
  elif [ $countNodes -eq 1 ] 
  then 
  
    # start one new node
    java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://173.249.58.30:4444/grid/register/ & 
    exit 0
    
  fi  
    

else # if there is NO HUB start new hub and two new nodes

  # kill all possible hubs and nodes for sure
  pkill -9 -f "selenium-server"

  # Start new hub
  java -jar selenium-server-standalone-3.141.59.jar -role hub & 
  java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://173.249.58.30:4444/grid/register/ & 
  java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://173.249.58.30:4444/grid/register/ & 
  exit 0

fi

我可以在 syslog 中看到脚本正在运行并尝试发送电子邮件。我因此安装了 postfix，但我看不到该消息。syslog 文件中没有更多信息。是否有任何其他日志可以收集有关 cron 作业的更多信息？几个小时后，我决定问这个问题。感谢帮助。

我需要制作应该运行如下内容的 bash 文件：

cd /opt/selenium-server/

java -jar selenium-server-standalone-3.141.59.jar -role hub

java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://173.249.58.30:4444/grid/register/

问题是，如果我运行第一个 java -jar 命令开始运行仍在运行的进程，而第二个 java 命令在第一个进程运行之前不会运行。

如何运行这两个命令，以便在第一个服务运行后启动第二个命令？可能这是运行 Selenium 服务器的完全错误的方式，但我没有找到更好的方法。谢谢。

我有一个非常简单的 bash 脚本，它在 root 用户下运行了 5 个命令。如果我一一手动运行命令，一切正常 - 没问题。但是当我通过命令将它作为 my-deploy.sh 文件运行时

bash /root/custom-scripts/deploy/my-deploy.sh 2>> /var/log/www-deploy/tatrytec.eu.log

这似乎是一个无穷无尽的过程。这是脚本：

#!/bin/bash
# Run this script as bash command like: bash create-apache-site.sh

cd /var/www/html/tatrytec.eu

git pull

# Change user bacause of composer install warrning
su vlado

composer install  --no-scripts

npm install --production

它开始运行，我可以在终端中看到 git pull 的结果。但随后它没有任何错误就死了，它仍在运行。我可以通过 ctrl+Y 停止它。我觉得那个用户有问题，但正如我之前写的那样，如果我一个接一个地运行命令，它就可以工作。我不明白。有人可以告诉我可能是什么问题吗？谢谢。

我的 Ubuntu/Apache 服务器上的网页很少。现在我不得不为一个域更改 DocumentRoot。在 xyz.conf 文件中更改 DocumentRoot 后，对域的请求与所需的 DocumentRoot 目录不匹配。Apache 将旧路径保留在缓存中。现在我需要重新启动 Apache，但不知道如何仅针对该域执行此操作。有人可以解释一下我该怎么做吗？非常感谢。

当我运行 rsync 命令将一个目录从一台服务器复制到另一台服务器时，我收到以下警告：Warning: Permanently added '111.222.33.40' (ECDSA) to the list of known hosts。该命令如下所示：

rsync -avz /root/custom-scripts  [email protected]:/root/

为什么这个命令会产生这个警告？它究竟是什么意思？
