升级原因：Gitlab无法删除项目，点删除按钮后项目依然存在，打开后提示“No repository”，（不确定是否这个版本问题，想通过版本升级重装一遍看能否解决问题）
升级过程：
时间：2022-04-27 当前最新版本GitLab Enterprise Edition 14.10.0-ee
1、官方指导说升级到最新版本直接
yum install -y gitlab-ee
Create a GitLab upgrade plan | GitLab
但是，我这儿执行后，提示没有可升级内容Nothing to do ，但是查看我的版本是14.6.0并不是最新版本；
于是按照安装时的步骤，重新添加安装包库
curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ee/script.rpm.sh | sudo bash
再次yum install -y gitlab-ee 正常升级安装
2、程序运行完成后，Gitlab无法访问，运行日志显示升级过程有错误，信息如下：

按提示看应该是有迁移过程失败，手动执行迁移命令，并打印详细信息
gitlab-rake db:migrate --trace
会提示出错误原因，我的执行后给出了解决办法：
sudo gitlab-rake gitlab:background_migrations:finalize[ProjectNamespaces::BackfillProjectNamespaces,projects,id,'[null\,"up"]']
然后执行：gitlab-rake db:migrate:status 查看迁移状态，此时都up了，至此升级问题解决完成
3、执行 gitlab-ctl reconfigure 重新配置，配置后无法访问
gitlab-ctl tail 后查看日志502
/var/opt/gitlab/gitlab-rails/sockets/gitlab.socket: connect: connection refused"
重启后解决
