Clone the forked project to your local machine: `$ git clone git@github.com:USERNAME/<forked_repo>` Configure remotes: `$ git remote add upstream git://github.com/<origin_repo>` Create a branch for new feature: `$ git checkout -b my-new-branch` Develop on my-new-branch branch only, but Do not merge my-new-branch branch to the your master (as it should stay equal to upstream master)!! Commit changes to my-new-branch branch: $ git add . $ git commit -m "commit message" Push branch to GitHub, to allow your mentor to review your code: `$ git push origin my-new-branch` Repeat steps 5-7 till development is complete. Fetch upstream changes that were done by other contributors: `$ git fetch upstream` Update local master: $ git checkout master $ git pull upstream master ATTENTION: any time you lost of track of your code – launch “gitk —all” in source folder, UI application come up that will show all branches and history in pretty view, explanation. Rebase my-new-branch branch on top of the upstream master: $ git checkout my-new-branch $ git rebase master In the process of the rebase, it may discover conflicts. In that case it will stop and allow you to fix the conflicts. After fixing conflicts, use git add . to update the index with those contents, and then just run:$ git rebase --continue Push branch to GitHub (with all your final changes and actual code):We forcing changes to your issue branch(our sand box) is not common branch, and rebasing means recreation of commits so no way to push without force. NEVER force to common branch. $ git push origin my-new-branch --force Created build for testing and send it to any mentor for testing. Only after all testing is done – Send a Pull Request.Attention: Please recheck that in your pull request you send only your changes, and no other changes!!Check it by command:git diff my-new-branch upstream/master submodule git submodule add submodule-repo path git submodule update --init --recursive git rm submodule-name git rm submodule-name --cached = ↩

Use netstat command to check whether the service is listening on port 8080 or not. netstat -antup | grep 8080 Output: tcp6 0 0 :::8080 :::* LISTEN 2428/java Firewall You may need to allow port 8080 in the firewall so that we can access Tomcat from external networks. firewall-cmd --permanent --add-port=8080/tcp firewall-cmd --reload
