1，安装gitlab-ce-16

1.1，rpm安装gitlab问题: NOKEY、signature check fail

解决办法

• 参考：https://docs.gitlab.com/omnibus/update/package_signatures.html
• rpm --import https://packages.gitlab.com/gitlab/gitlab-ce/gpgkey/gitlab-gitlab-ce-3D645A26AB9FBD22.pub.gpg

# gitlab-ce-16可能会遇到以下问题
test1:/opt # rpm -ivh gitlab-ce-16.0.3-ce.0.el7.x86_64.rpm  --force
warning: gitlab-ce-16.0.3-ce.0.el7.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID f27eab47: NOKEY
error: [upel]: gitlab-ce NOKEY
error: [upel]: gitlab-ce signature check fail
error: [upel]: gitlab-ce NOKEY
error: [upel]: gitlab-ce signature check fail

1.2, docker 启动 gitlab: ThreadError: can’t create Thread: Operation not permitted

• 解决办法：添加参数 --privileged=true ，将docker容器提权到root

 docker run --privileged=true  -d --publish 8888:80  --name gitlab --restart always gitlab/gitlab-ce

2，安装gitlab-ce-14

虚拟机主机名	cpu、内存配置	启动gitlab后内存占用
c71	1core, 2g	1.5G

# gitlab-ce-14 安装很顺利, 提示依赖问题（直接用--nodeps忽略即可）
[root@c74 ~]# rpm -ivh gitlab-ce-14.0.6-ce.0.el7.x86_64.rpm

GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:sudo gitlab-ctl reconfigureFor a comprehensive list of configuration options please see the Omnibus GitLab readme

#          2. Password hasn't been changed manually, either via UI or via command line.
#
#          If the password shown here doesn't work, you must reset the admin password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.Password: tqeVom/jSx0GlfrSFlI7DLSyhIVdoJmOxWlek5UF4bE=# NOTE: This file will be automatically deleted in the first reconfigure run after 24 hours.
