Amazon EC2-Apache服务器重启问题 [英] Amazon EC2 - Apache server restart issue

问题描述

当我运行此命令时

sudo/etc/init.d/httpd重新启动

sudo /etc/init.d/httpd restart

它给出以下错误

停止httpd:[失败]

Stopping httpd: [FAILED]

开始httpd:(98)已经使用的地址:make_sock:无法绑定到地址[::]:80 (98)地址已在使用中:make_sock:无法绑定到地址0.0.0.0:80 没有可用的侦听套接字，正在关闭 无法打开日志[失败]

Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80 (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 [FAILED]

我使用

netstat -lnp | grep:80(给出下面的输出)

netstat -lnp | grep :80 (it gives below output)

tcp 0 0 ::: 80 ::: * LISTEN 21739/httpd

tcp 0 0 :::80 :::* LISTEN 21739/httpd

为什么我无法使用sudo/etc/init.d/httpd restart来停止停止apache?

why i am not able to stop stop apache by using sudo /etc/init.d/httpd restart?

下面的命令可以正常工作

below commands work without issue

sudo apachectl停止

sudo apachectl stop

sudo apachectl开始

sudo apachectl start

我正在使用Amazon EC2的Linux微型实例

i am using linux micro instance of amazon ec2

推荐答案

当我从源代码安装apache时遇到了这个问题，但随后尝试运行

I ran into this problem when I installed apache from source, but then tried to run

$ sudo /etc/init.d/httpd restart 

使用的是预先安装的apache版本. /etc/init.d/httpd中的stop指令未删除启动apache的源安装版本时创建的httpd.pid文件.

which was using a pre-installed version of apache. The stop directive in /etc/init.d/httpd was not removing the httpd.pid file that was created when starting the source-installed version of apache.

要确定这也是您遇到问题的原因，请查找运行时设置httpd.pid文件的位置

To determine if this is also the reason for your problem, find where the httpd.pid file is getting set when you run

$ sudo apachectl start

如果从源代码安装并且apache2位于/usr/local/apache2中，则应该在/usr/local/apache2/logs中创建httpd.pid文件.当您通过运行停止apache

If you installed from source and apache2 is living in /usr/local/apache2, then the httpd.pid file should get created in /usr/local/apache2/logs. When you stop apache by running

$ sudo apachectl stop

该文件应被删除.因此，要测试httpd.pid文件是否引起了您的问题，请通过调用

this file should get removed. So to test if the httpd.pid file is causing your problem, start apache by calling

$ sudo apachectl start

并找到httpd.pid文件.然后尝试通过使用

and locate the httpd.pid file. Then try stopping apache by using

$ sudo /etc/init.d/httpd stop

如果原始的httpd.pid文件仍然存在，那么这就是为什么当您使用app时无法启动

If the original httpd.pid file is still present, then that is why apache is unable to start when you use

$ sudo /etc/init.d/httpd start

要使我的/etc/init.d/httpd文件正常工作，我将调用apachectl明确地放在了start和stop方法中:

To get my /etc/init.d/httpd file to work correctly, I explicitly put the call to apachectl in the start and stop methods:

#!/bin/bash
# /etc/init.d/httpd
#
# Path to the apachectl script, server binary, and short-form for messages. 
apachectl=/usr/local/apache2/bin/apachectl 
httpd=/usr/local/apache2/bin/httpd 
pid=/usr/local/apache2/logs/httpd.pid 
prog=httpd 
RETVAL=0

start() {
    echo -n $"Starting $prog: "
    $apachectl -k start
    RETVAL=$?
    echo
    return $RETVAL
}
stop() {
    echo -n $"Stopping $prog: "
    $apachectl -k stop
    RETVAL=$?
    echo
}
