Problem :
So I am using nginx as my server if that helps at all. I also use Putty as my connection manager as well.
So while setting up domains here and there under nginx, there seems to be a difference in colors for some of the domains. I am really unsure why. Like if it is a concern at all.
I just setup a domain and it appears red as shown: http://puu.sh/m4scc/1baa60c2e9.png
I’ve hidden domain names for privacy reasons. The tutorial I used to setup nginx on my server is: https://www.digitalocean.com/community/tutorials/how-to-set-up-nginx-server-blocks-on-centos-7
Information such as serverblock info is not what I use on there if that was a question of the viewers.
You may also see in my image two domains don’t have a directory on the right side. I believe during the setup of those 2, I did not create a symbolic link between them. But no performance/uptime issues with them.
EDIT:
I have also read this that my friend linked me, but they don’t seem to correlate with what I am facing: https://stackoverflow.com/questions/6942479/what-do-each-of-puttys-text-colours-represent
EDIT 2:
Ok so I solved my problem in a way. More of getting it to be blue. It looks like there was a small typo in the symbolic link, so it was read because it must of been invalid. Typed it all out again and it appears blue. Staff can close.
Solution :
The red link is link to non-existing file and means that it is invalid. It is because of missing slash / in the beginning.
For more, the other colors are dependent on different access permissions, as you have already found out.
