大佬教程收集整理的这篇文章主要介绍了amazon-web-services – 为什么我得到ElasticBeanstalk :: ExternalInvocationError?大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。

我的应用程序构建在RubyOnRails上,并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弹性beanstalk的.ebextensions文件夹中的脚本:

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"

但是我收到了这个错误:

[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到实例并执行sudo服务nginx重新加载它将正常执行..
任何的想法?

server {

    location /assets {

service nginx configtest结果:

$sudo service nginx configtest
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
最佳答案
命令:“sudo service nginx reload”不是必需的,因为NGINX服务在每次成功部署后自动重启.您可以从配置文件中删除它.

您可能会遇到CDN服务到期的延迟,请尝试刷新缓存或直接对EB网址进行测试.
