what about auto reloading working dir’s status in NERRDTREE?

## what happened when I first use __rpm -Uvh ../nginx/*.rpm__ to install nginx on centos7 on EC2:error: Failed dependencies: openssl is needed by … … ```
- and since I don’t think it would be necessary to know what really happens for yum managing those dependencies under different OS versions, I guess it’d be better we just google the rpm files and download ‘em now lol
- actually I found this page helpful
urls I needed for nginx’s rpm dependencies
- https://centos.pkgs.org/7/centos-x86_64/openssl-1.0.2k-8.el7.x86_64.rpm.html
- http://mirror.centos.org/centos/7/os/x86_64/Packages/gd-2.0.35-26.el7.x86_64.rpm
- oh … damn it – too many
- OK – finally I tried not to install nginx offline (to be specific, from rpm files), here’s the new resource
- And the previous method worked out. So now I have a dummy nginx on my EC2
lets review how to find some files:
find /some/dir -name "yourExactFileName"
Git
Damn it … I accidentally delete my Gitlab dirs …
What if I’d like to have different remotes? Say I have a local repository and a cloud one (perhaps I just setup on AWS), which may not be on Gitlab since I don’t want to go public with something credential and I don’t want to pay some extra fee for private repositories (but maybe Bitbucket could be a choice?)
- then, to my current knowledge, it would be best to revisit what a remote is and what does git push origin master exactly do?
- clear explanation
