【问题描述】:
我的应用程序是基于 RubyOnRails 构建的,它使用乘客部署为弹性 beanstalk 应用程序,我正在尝试将标头添加到 nginx 服务器并重新启动它,这是我的配置文件,来自 aws elastic beanstalk 中 .ebextensions 文件夹的脚本:
packages:
yum:
nginx: []
files:
"/etc/nginx/conf.d/webapp.conf" :
mode: "000644"
owner: root
group: root
content: |
server {
location /assets {
alias /var/app/current/public/assets;
gzip_static on;
gzip on;
expires max;
add_header Cache-Control public;
}
location /public {
alias /var/app/current/public;
gzip_static on;
gzip on;
expires max;
add_header Cache-Control public;
}
}
# This reloads the server, which will both make the changes take affect and makes sure the config is valid when you deploy
container_commands:
01_reload_nginx:
command: "sudo service nginx reload"
但是我得到了这个错误:
[2017-12-13T06:23:48.635Z] ERROR [17344] : Command CMD-AppDeploy failed!
[2017-12-13T06:23:48.635Z] INFO [17344] : Command processor returning results:

/var/log/eb-activity.log:

虽然如果我 ssh 进入实例并执行 sudo service nginx reload 它将正常执行..
有什么想法吗?

service nginx configtest 结果:
$ sudo service nginx configtest
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

【问题讨论】:
-
@simo:你是通过 eb cli 部署的吗?如果是这样,您可以添加您用于部署更改的命令吗?您还可以重现错误然后运行 eb 日志并将一些输出发布到您的问题吗?谢谢。
-
是的,我使用 eb cli 部署,命令是
eb deploy my-app -v我在上面添加了 请求资产的标头和 缺少的标头,请查看它们.我认为,在深入了解container_commands的错误之前,至少要检查为什么实际上错过了丢失的标题?因为我已经通过命令行成功重新启动了 nginx,但仍然缺少年龄标头。请检查上面的webapp.conf,如果您需要更多信息,请告诉我 -
还有一个问题:您能解释一下 nginx 配置更改的预期目标是什么吗?
-
我需要将
access-control-max-age和age标头与服务资产一起传递以利用浏览器缓存
