[Note] Update to production environment (AWS EC2)

Premise

--I'm writing an application in Rails --The initial settings of AWS have been completed, the EC2 instance etc. have been started, and the application has already been deployed. --The automatic deployment settings by Capistrano have been completed.

Purpose of this article

--Since you made changes locally to the created application, you want to reflect the changes in the production environment on AWS. --I always forget how to push AWS EC2, so I want to post it instead of a memorandum

procedure

1. Push local changes to the master branch on github

2. Log in to EC2

terminal

~ % cd .ssh
.ssh % ssh -i example.pem ec2-user@Elastic IP of the application you want to update

3. Move to the application repository in EC2

terminal

[ec2-user@ip-○○○-○○-○○-○○ ~]$ cd /var/www/Application name

4. Drop the currently running server

terminal

[ec2-user@ip-○○○-○○-○○-○○ Repository name]$ ps aux | grep unicorn
↓
「unicorn master -Find the process ID with the letter c "
↓
[ec2-user@ip-○○○-○○-○○-○○ Repository name]$kill process ID
↓
Run exit to log out of your EC2 instance

5. Perform automatic deployment in the local directory of the application you want to update

terminal

Application name% bundle exec cap production deploy

6. Access from Elastic IP. Check if the changes are reflected

that's all.
