the signing failure problem in the first logining of gitlab-ce and solution sharing

problem

In this case,I was in trouble when I install the gitlab-ce service in my ubuntu system.The account I had create was losing efficacy.Because of this,I look up the material on the internet and the solution is to update the configuration of your gitlab-ce.

solution

• 1.we should change our externel_url

sudo gedit /etc/gitlab/gitlab.rb

and another port also need to update
make your configuration rework

gitlab-ctl reconfigure 
gitlab-ctl restart

2. Second step is set your super account

• enter your bin catalogue

cd /opt/gitlab/bin

• open your gitlab-ce console

sudo gitlab-rails console production

input as following

[root@gitlab bin]# sudo gitlab-rails console -e production
