System development or Technical something

Using Git repository on GitLab.

After preparing:

git clone

$ git clone http://username01@172.16.10.25/testgrp/testpj.git
Cloning into 'testpj'...

setting user info:

$ git config user.name username01

$ git config user.email <mail address>

prepare sample file “README.md”

$ vi README.md

$ cat README.md
Test Message: hello Gitlab!

Prepare group, project and user before using GitLab

After installation:akai-tsuki.hatenablog.com

set pass for root user.

input password of root.
f:id:akai_tsuki:20170527174634p:plain

login by root.
f:id:akai_tsuki:20170527181231p:plain

f:id:akai_tsuki:20170527181403p:plain

1. create Group

f:id:akai_tsuki:20170527181418p:plain

f:id:akai_tsuki:20170527181536p:plain

2. create PJ

f:id:akai_tsuki:20170527181546p:plain

f:id:akai_tsuki:20170527181603p:plain

3. create users

f:id:akai_tsuki:20170527181725p:plain

f:id:akai_tsuki:20170527181738p:plain

4. add member to group

f:id:akai_tsuki:20170527181822p:plain

After adding member:
f:id:akai_tsuki:20170527181833p:plain

At this point we can not see icon image of added user,
because I don’t change external_url parameter in /etc/gitlab/gitlab.rb,
I need to chenage form hostname to ip address for this parameter in my environment.

change external_url parameter

# cp -p /etc/gitlab/gitlab.rb{,.org}
# vi /etc/gitlab/gitlab.rb
# diff /etc/gitlab/gitlab.rb /etc/gitlab/gitlab.rb.org
13c13
< external_url 'http://172.16.10.25'
