Apache2 不工作

Question

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。 有关详细信息，请参阅“systemctl status apache2.service”和“journalctl -xe”。 这是显示 systemctl 状态 `apache2.service 的下一个错误 tex

：

Answer 1

在日志中显示端口 80（apache2 被另一个应用程序使用）：-

5 月 31 日 14:40:49 alpha-To-be-fill-by-OEM apache2[23986]: (98)Address already in use: AH00072: make_sock: 无法绑定到地址 [::]:80

要解决此问题，请停止现有正在运行的应用程序并尝试启动 apache2。

要检查端口 80 上正在运行的应用程序：-

    sudo lsof -i:80

获取正在运行的应用程序的 pid 并使用以下命令终止应用程序：-

   sudo pkill -9 <pid of running application>

再次运行 apache2 应用程序：-

    sudo service apache2 start

Answer 2

export APACHE_PID_FILE=/var/run/apache2/apache2$SUFFIX.pid

在您的/etc/apache2/envvars文件中添加这一行

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=
 fi

更新

no listening sockets available 。 您面临这个问题是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 获得了端口 80 ，您需要终止该进程 1588。

sudo kill -9 1588

现在你可以启动你的 apache

解决方案2

转到/etc/apache2/ports.conf并取消注释Listen 80

**如果您的 Apache2 不工作并且返回如下 **

别担心，我有你的解决方案

首先检查你的机器是否有 Nginx 服务在你的系统中运行

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并使用启动服务

sudo systemctl  start apache2

干得好
