在AWS Elastic Beanstalk中从.ebextensions文件夹运行脚本 [英] Running a script from .ebextensions folder in aws elastic beanstalk

问题描述

我正在尝试从上载战争开始运行脚本，所以这是配置的内容

I am trying to run a script from when war is uploaded so here is the contents of configurations

container_commands:
    01_setup_apache:
        command: "cp .ebextensions/enable_mod_deflate.conf /etc/httpd/conf.d/enable_mod_deflate.conf"
    02_setup_script:
        command: "sudo su root"
    03_setup_script:
        command: "sudo mkdir -p /home/dev"
    04_setup_script:
        command: "sudo chmod 777 /home/dev -R"
    05_setup_script:
        command: "sudo cp .ebextensions/scripts/setup.sh /home/dev/"
    06_setup_script:
        command: "sudo chmod +x /home/dev/setup.sh"
    07_setup_script:
        command: "sudo /home/dev/setup.sh"
    08-restart-apache:
        command: "sudo /etc/init.d/httpd restart"

我尝试了所有事情，但是部署总是在执行setup.sh时失败.在上面的示例中，它在 07_setup_script

I tried every thing but deployment always fail on executing setup.sh. In above example it fails on 07_setup_script

这是日志内容

] : Starting activity...
/Command 01_setup_apache] : Starting activity...
/Command 01_setup_apache] : Completed activity.
/Command 02_setup_script] : Starting activity...
/Command 02_setup_script] : Completed activity.
/Command 03_setup_script] : Starting activity...
/Command 03_setup_script] : Completed activity.
/Command 04_setup_script] : Starting activity...
/Command 04_setup_script] : Completed activity.
/Command 05_setup_script] : Starting activity...
/Command 05_setup_script] : Completed activity.
/Command 06_setup_script] : Starting activity...
/Command 06_setup_script] : Completed activity.
/Command 07_setup_script] : Starting activity...
/Command 07_setup_script] : Activity execution failed, because: sudo: unable to execute /home/dev/setup.sh: No such file or directory
   (ElasticBeanstalk::ExternalInvocationError)

如果实例上的 ssh 那里没有文件夹或文件(/home/dev)或(/home/dev/setup.sh)，则似乎先前的命令未执行，但日志显示其完成

If ssh on instances there is no folder or file over there (/home/dev) or ( /home/dev/setup.sh) it seems previous commands were not executed but log says its completed

我知道有一种在运行时创建脚本文件的方法，但是我们可以避免这种情况，仅使用上述方法即可.

I know there is way to create a script file on run time, but can we avoid that and just use the above method.

推荐答案

几个问题.您根本不应该开始尝试管理主目录/目录结构，这绝对不是beantalk最佳实践的范围.同样不要以sudo的身份运行事物，它会以root身份执行钩子.

A couple of issues. You shouldn't start trying to manage a home directory/directory structure at all, that's definitely outside of beanstalk best-practices. Also don't run things as sudo, it executes hooks as root.

执行以下操作:

在.ebextension/foo.config中:

container_commands:
  01_restart_httpd:
    command: /etc/init.d/httpd restart

files:
   /etc/httpd/conf.d/enable_mod_deflate.conf:
    mode: "000644"
    owner: root
    group: root
    content: |
      #content of your conf

或者也是

files:
   /etc/httpd/conf.d/enable_mod_deflate.conf:
    mode: "000644"
    owner: root
    group: root
    content: |
      #content of your conf

  /opt/elasticbeanstalk/hooks/appdeploy/post/50_restart_httpd:
    mode: "000777"
    owner: root
    group: root
    content: |
      #!/bin/sh
      /etc/init.d/httpd restart
