完全卸载 GitLab

That directory is populated with gitlab-ce reconfigure command after installation and holds variable data, configurations related to gitlab-ce package.

The recommended process to uninstall it was

1、 Remove services

sudo gitlab-ctl uninstall

2、 Clean any data generated by usage of the package

sudo gitlab-ctl cleanse

3、 You may also want to remove any accounts you configured. To do so

sudo gitlab-ctl remove-accounts

4、 Then remove the package using （博主注：这里卸载的是 ce）

sudo dpkg -P gitlab-ce

Furthermore, gitlab-ce uses these directories (as described here)

• /opt/gitlab holds application code for GitLab and its dependencies.
• /var/opt/gitlab holds application data and configuration files that gitlab-ctl reconfigure writes to.
• /etc/gitlab holds configuration files for omnibus-gitlab. These are the only files that you should ever have to edit manually.
• /var/log/gitlab contains all log data generated by components of omnibus-gitlab.
