# 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](http://digitalcube-8114095.hs-sites.com/knowledge/log-in-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](https://github.com/Launch-with-1-Click/lw1-amimoto2).*For Amazon Linux 1, refer to *[Launch-with-1-Click/lw1-amimoto](https://github.com/Launch-with-1-Click/lw1-amimoto/tree/2016.01/attributes).*
