yum安装
yum install gitlab-ce –y
gitlab配置
vim /etc/gitlab/gitlab.rb

gitlab_rails['gitlab_email_reply_to'] = 'gitlab2015@163.com'
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.163.com"
gitlab_rails['smtp_port'] = 25
gitlab_rails['smtp_user_name'] = "gitlab2015@163.com"
gitlab_rails['smtp_password'] = "nxgfvizafijytymx"

重置配置，使修改生效
gitlab-ctl reconfigure
How to reset your root password
Log into your server with root privileges. Then start a Ruby on Rails console.
Start the console with this command:
gitlab-rails console production
Wait until the console has loaded.
There are multiple ways to find your user. You can search for email or username.
user = User.where(id: 1).first
or
user = User.find_by(email: 'admin@local.host')
Now you can change your password:
user.password = 'secret_pass' user.password_confirmation = 'secret_pass'
It's important that you change both password and password_confirmation to make it work.
Don't forget to save the changes.
user.save!
Exit the console and try to login with your new password.
