我在ubuntu下删除apache2时遇到问题。我尝试的是：
sudo apt-get remove apache2
sudo apt-get purge apache2
不幸的是，在任何上级命令之后，仍然有文件：
sudo find / -name "apache2"
/var/log/apache2
/var/lib/update-rc.d/apache2
/var/cache/apache2
/usr/share/doc/apache2.2-common/examples/apache2
/usr/share/apache2
/usr/lib/apache2
/usr/lib/apache2/mpm-event/apache2
/usr/lib/apache2/mpm-itk/apache2
/usr/lib/apache2/mpm-worker/apache2
/usr/lib/apache2/mpm-prefork/apache2
/usr/sbin/apache2
/run/apache2
/run/lock/apache2
/etc/init.d/apache2
/etc/apache2
/etc/cron.daily/apache2
/etc/default/apache2
/etc/logrotate.d/apache2
当我跑sudo /etc/init.d/apache2 start
* Starting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Action 'start' failed.
The Apache error log may have more information.
在浏览器中键入本地主机后，它会响应：
Forbidden
You don't have permission to access / on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
此文件会干扰新的 apache 服务器安装吗？我已经检查了它们，但没有发现任何间歇。
编辑：上部输出是在删除服务器之后。从sudo find / -name "apache2"中删除所有文件后，我确实再次安装了sudo apt-get install apache2. sudo /etc/init.d/apache2输出：
* Starting web server apache2 Segmentation fault
Action 'start' failed.
The Apache error log may have more information.
但是错误.log和访问.log是空的。
阿帕奇安装：
sudo apt-get install apache2

它只要求1,240 kB空间正常吗？
第一站阿帕奇：
sudo service apache2 stop
然后，删除 apache2 软件包和依赖项：
sudo apt-get purge apache2 apache2-utils apache2.2-bin apache2-common
sudo apt-get autoremove --purge
如果您手动修改或安装了内容，apt 可能不会将其删除。检查剩余内容：
whereis apache2
看看这些目录中的内容，如果您确信要删除它，请手动删除目录，如下所示：
sudo rm -Rf /etc/apache2 /usr/lib/apache2 /usr/include/apache2

从 Ubuntu 中删除 apache2
从本地主机中完全删除
第一次检查当前状态
service apache2 status
如果它处于活动状态（正在运行）写下一个
sudo apt remove apache2*
使用 y 说"是
"祝你有美好的一天:)
以这种方式删除并安装 apache2：
sudo apt-get purge apache2
sudo apt-get install apache2
