【问题描述】：

我需要在 aws 中延长我的 beanstalk 的超时时间，我在负载均衡器中增加了超时时间，但我仍然面临 502 错误。所以我尝试在提供文件的.ebextensions 文件夹中添加httpd confing

# Managed by Elastic Beanstalk
PidFile run/httpd.pid

# Enable TCP keepclive
Timeout 300
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 300

<IfModule worker.c>
StartServers        10
MinSpareThreads     250
MaxSpareThreads     250
ServerLimit         10
MaxClients          250
MaxRequestsPerChild 1000000
</IfModule>

Listen 80

Include conf.d/elasticbeanstalk/*.conf

当我尝试在 beanstalk 上部署它时，我开始遇到错误：

[实例：i-0c436613676c84739] 实例上的命令失败。返回代码：1 输出：（截断）...pd.conf AH00534：httpd：配置错误：未加载 MPM。执行失败'/usr/sbin/apachectl -t -f /var/elasticbeanstalk/staging/httpd/conf/httpd.conf' 执行失败'/usr/sbin/apachectl -t -f /var/elasticbeanstalk/staging/ httpd/conf/httpd.conf'。挂钩 /opt/elasticbeanstalk/hooks/appdeploy/pre/03_configure_proxy.sh 失败。有关更多详细信息，请使用控制台或 EB CLI 检查 /var/log/eb-activity.log。

我尝试在 httpd.conf 文件中添加 npm 模块，但这样做我面临其他问题并且它永远不会结束。 此文件是否需要更正？

【参考方案1】：

无论出于何种原因，该 EC2/beanstalk 映像缺少此文件：

/etc/httpd/conf.modules.d/00-mpm.conf

只需使用以下文本创建它：

# Select the MPM module which should be used by uncommenting exactly
# one of the following LoadModule lines.

# prefork MPM: Implements a non-threaded, pre-forking web server
# See: http://httpd.apache.org/docs/2.4/mod/prefork.html
#
# NOTE: If enabling prefork, the httpd_graceful_shutdown SELinux
# boolean should be enabled, to allow graceful stop/shutdown.
#
LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

# worker MPM: Multi-Processing Module implementing a hybrid
# multi-threaded multi-process web server
# See: http://httpd.apache.org/docs/2.4/mod/worker.html
#
#LoadModule mpm_worker_module modules/mod_mpm_worker.so

# event MPM: A variant of the worker MPM with the goal of consuming
# threads only for connections with active processing
# See: http://httpd.apache.org/docs/2.4/mod/event.html
#
#LoadModule mpm_event_module modules/mod_mpm_event.so

然后运行sudo systemctl restart httpd
