Migrations & Seeding

What are migrations??

Migrations are a way to make database changes or updates, like creating or dropping tables, as well as updating a table with new columns with constraints via generated scripts. We can build these scripts via the command line using knex command line tool.

To learn more about migrations, check out this article on the different types of database migrations!

1. Avoid Using FTP, Telnet, And Rlogin / Rsh Services on Linux

Under most network configurations, user names, passwords, FTP / telnet / rsh commands and transferred files can be captured by anyone on the same network using a packet sniffer. The common solution to this problem is to use either OpenSSH , SFTP, or FTPS (FTP over SSL), which adds SSL or TLS encryption to FTP.

Type the following command to delete NIS, rsh and other outdated service:

sudo apt --purge remove xinetd nis yp-tools tftpd atftpd tftpd-hpa telnetd rsh-server rsh-redone-server

	To show all the remotes the repo is pointing to:
	`git remote -v`

	To add the upstream repo to the list of remotes:
	`git remote add upstream <[email protected]:<repo-owner>/<repo-name.git>`

	To fetch all the changes from upstream to the local repo:
	`git fetch upstream`

	To set up the master branch to track the remote master branch from upstream
