加载代理模块时，Docker 中的 Apache 2.4 httpd 无法启动

Question

我正在用 Docker 构建一个 Apache2.4 堆栈。在配置期间，服务器没有启动：

apache-php-fpm-docker_apache_1 exited with code 1

在添加以下行加载模块后发现这种情况：

LoadModule proxy_module modules/mod_proxy.so

我认为我做错了什么，但我怎样才能得到错误信息以查看问题所在？

我已经尝试过的

运行httpd -h我看到以下选项：

-e level           : show startup errors of level (see LogLevel)

所以我ENTRYPOINT httpd -k start -e debug现在尝试查看一些日志，但没有看到错误。并且网络服务器不会启动，即使错误已修复。

首先，添加ErrorLog /proc/self/fd/2到您的http.conf以启用错误日志。然后，我看到了你的情况的错误日志：shubuntu1@shubuntu1:~/aa$ docker run -idt -v ${PWD}/httpd.conf:/usr/local/apache2/conf/httpd.conf -p 9000:80 httpd:2.4fd0d0b45bd8e25e5ce8219d6b96e5b446307d7a76bf7e3eecb47e23d93b04368shubuntu1@shubuntu1:~/aa$ docker ps -aCONTAINER ID&nbsp; &nbsp; &nbsp; &nbsp; IMAGE&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;COMMAND&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; CREATED&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;STATUS&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; PORTS&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;NAMESfd0d0b45bd8e&nbsp; &nbsp; &nbsp; &nbsp; httpd:2.4&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;"httpd-foreground"&nbsp; &nbsp;3 seconds ago&nbsp; &nbsp; &nbsp; &nbsp;Exited (1) 1 second ago&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;agitated_edisonshubuntu1@shubuntu1:~/aa$ docker logs agitated_edison[Wed Jun 19 08:45:20.774433 2019] [core:emerg] [pid 1:tid 139720185319488] (22)Invalid argument: AH00024: Couldn't set permissions on the proxy mutex; check User and Group directives[Wed Jun 19 08:45:20.774495 2019] [proxy:crit] [pid 1:tid 139720185319488] (22)Invalid argument: AH02478: failed to create proxy mutexAH00016: Configuration Failed从错误日志：创建代理互斥体时似乎失败proxy_module。所以，我在旁边添加httpd.conf，然后一切正常：<IfModule unixd_module>User daemonGroup daemon</IfModule>
