修改配置文件

vim /etc/gitlab/gitlab.rb

修改以下信息

external_url http://192.168.2.61:80
......
gitlab_rails[time_zone] = Asia/Shanghai
gitlab_rails[gitlab_email_from] = xxxxxx@163.com
......
gitlab_rails[smtp_enable] = true
gitlab_rails[smtp_address] = "smtp.163.com"
gitlab_rails[smtp_port] = 25
gitlab_rails[smtp_user_name] = "xxxxxx@163.com"
gitlab_rails[smtp_password] = "111111" # 客户端授权密码
gitlab_rails[smtp_domain] = "163.com"
gitlab_rails[smtp_authentication] = "login"
gitlab_rails[smtp_enable_starttls_auto] = true
......
user["git_user_email"] = "xxxxxx@163.com"

只要修改配置文件就要reconfigure

sudo gitlab-ctl reconfigure

Default admin account has been configured with following details:
Username: root
Password: You didnt opt-in to print initial root password to STDOUT.
Password stored to /etc/gitlab/initial_root_password. This file will be cleaned up in first reconfigure run after 24 hours.

NOTE: Because these credentials might be present in your log files in plain text, it is highly recommended to reset the password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.

gitlab Reconfigured!

出现上面表示成功了，默认密码根据提示保存在

sudo cat /etc/gitlab/initial_root_password

访问web页面

账号/密码 root / 密码在文件里面复制出来

Gitlab设置中文界面

完成
