我正在尝试通过pipeline 将Laravel 应用程序部署到AWS EB，当我部署该应用程序时，当我检查日志文件的最后100 行时，在最近的事件中出现错误我发现了这个错误：

2020/10/18 00:43:08.443797 [INFO] Executing instruction: Install composer dependencies
2020/10/18 00:43:08.443819 [INFO] installing composer dependencies...

Fatal Error Insufficient shared memory!

我在.ebextensions 内有一个名为01_deploy.config 的文件，包含以下内容：

option_settings:
# Point the app root to the public/ folder.
- namespace: aws:elasticbeanstalk:container:php:phpini
    option_name: document_root
    value: /public

# Set here your php.ini `memory_limit` value.
- namespace: aws:elasticbeanstalk:container:php:phpini
    option_name: memory_limit
    value: 256M

container_commands:
01_install_composer_dependencies:
    command: "sudo php /usr/bin/composer.phar install --no-dev --no-interaction --prefer-dist --optimize-autoloader"
    cwd: "/var/app/current"

02_install_node_dependencies:
    command: "sudo npm install"
    cwd: "/var/app/current"

 05_run_migrations:
   command: "php artisan migrate --force"
   cwd: "/var/app/current"
   leader_only: true

【问题讨论】：

"共享内存不足！" - 可能需要更多内存。您使用的是什么实例类型？
@Marcin 是 tc2.micro！但我没有选择它，它只是默认从EB创建的
您可以尝试使用更大的实例。您可以在 EB 配置菜单中更改实例类型。
@Marcin 我把它改成了小实例，然后部署我得到了新的错误（更新的问题）
你能检查一下`/var/log/cfn-init-cmd.log`，看看哪个命令失败了，为什么？

【解决方案1】：

选项 1：您可以在本地安装 composer 并将供应商文件夹包含在 zip 存档中，同时将其发送到 Elastic Beanstalk

选项 2：使用这个 container_command

command: "sudo php -d memory_limit=-1 /usr/bin/composer.phar install --no-dev --no-interaction --prefer-dist --optimize-autoloader"
