我使用Linux Mint。当我尝试重新启动apache时显示下一条消息。 apache2.service的作业失败，因为控制进程退出并显示错误代码。请参阅＆＃34; systemctl status apache2.service＆＃34;和＆＃34; journalctl -xe＆＃34;详情。这里是显示systemctl状态`apache2.service

export APACHE_PID_FILE=/var/run/apache2/apache2$SUFFIX.pid
在/etc/apache2/envvars文件中添加此行
如果没有suffix，则必须添加
#for supporting multiple apache2 instances
if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
SUFFIX=

no listening sockets available。您正面临此问题，因为另一个应用程序/服务在您的Ubuntu服务器上获取了端口80。
现在您需要杀死获取端口80的进程。您可以使用以下命令轻松找到： -
sudo netstat -ltnp | grep ':80'
这将返回如下内容： -
tcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN 1588/aolserver4-nsd
对于上述情况进程号1588获取端口80，您需要终止该进程1588。
sudo kill -9 1588
现在你可以开始你的apache
了解决方案2
转到/etc/apache2/ports.conf并取消注释Listen 80
答案 1 :(得分：0)
在日志中显示端口（apache2的端口80被另一个应用程序使用）：-
5月31日14:40:49由OEM apache2填充Alpha2 [23986] ：( 98）地址已在使用中：AH00072：make_sock：无法绑定到地址[::]：80 < / p>
要解决此问题，请停止现有的正在运行的应用程序，然后尝试启动apache2。
要检查端口80上正在运行的应用程序，请执行以下操作：-
sudo lsof -i:80
获取正在运行的应用程序的pid，然后使用以下命令杀死该应用程序：-
sudo pkill -9 <pid of running application>
再次运行apache2应用程序：-
sudo service apache2 start

别担心，我有办法给你
首先使用
签入您的机器是否有Nginx服务在您的系统中运行sudo systemctl status nginx.service
如果它正在运行停止服务使用
sudo systemctl stop nginx.service
然后使用
检查端口 80 是否有任何进程在该端口上运行sudo lsof -i tcp:80
输出：
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
anydesk 950 root 22u IPv4 39398 0t0 TCP bitcot-Latitude-7480:35993->hosted.by.datacamp.co.uk:http (ESTABLISHED)
使用
杀死进程sudo kill 950
现在您的 apache2 已准备就绪，要启动服务，请打开一个新终端 Ctrl + Ail + T 并使用
sudo systemctl start apache2
给你
