Elastic Beanstalk Rails – 修改passengerconfigurationpassenger_max_pool_size

我意识到这是一个旧post，但是没有答案。

最好的select是在您的项目的根目录中使用.ebextensions目录，并添加一个conf文件来configuration乘客。 我在我的项目中创build了一个.ebextensions/01_passenger.conf文件。

对于此文件的内容部分，您可能需要复制位于此处的现有乘客init文件/opt/elasticbeanstalk/support/conf/passenger

我稍微修改了它，在命令选项中包含了--max-pool-size=${PASSENGER_MAX_POOL_SIZE:-6} 。 您可以使用Beanstalk环境variables来覆盖池大小的默认值6。
