This document describes how to enable services at startup for auto scale-out CVMs by modifying the /etc/rc.d/rc.local file. Manual intervention is not expected throughout the scale-out process where auto scaling is used. Therefore, we recommend that you set the service to be started upon starting of the CVM to be automatically added. Such services include:
httpd service
mysqld service
php-fpm service
tomcat service
Other services
Directions

5. Press :wq to save and exit. Then, the website can be automatically accessed after the instance is restarted.
(Optional) Verifying the configuration
Restart the server (with the reboot command, or through the console). After the server is restarted, refresh the page on the website without logging in to the server to check whether a response is returned. If yes, the configuration was successful.
Creating images
You can create an image based on the instance and use this image when creating the launch configuration. For more information, see.
