4. Managing AMIMOTO Config

Edit settings for NGINX, PHP, and more for AMIMOTO AMI

AMIMOTO AMIs use a few config files to manage the entire server. These settings are provisioned using Chef.

If you're not familiar with Chef, no worries, we write the scripts for you and all you need to do is add your preferred settings and run one command.

It's an easy way to handle all the settings and apply them to multiple environments. amimoto.json stores all parameters for the server. Editing this file, you change PHP and NGINX settings and maintain those settings during reboot. The parameters on amimoto.json overwrites your direct changes to PHP or NGINX.

Only root user can edit it. To role as a root user, please check Login as root document.

Configurable values.

Here are some example: client_max_body_size for Nginx, max_allowed_packet  for MySQL,  memory_limit for PHP and more. You can modify all of the values listed on Launch-with-1-Click/lw1-amimoto2. For Amazon Linux 1, refer to Launch-with-1-Click/lw1-amimoto.

File to edit

Commands after editing the file.

After modifying, run all of the following commands.

1. Provisioning as a root user
