很久不用Linux和gitlab 的一些操作

挺久没有登陆 电脑 了 

今天登陆 linux 主机突发 密码忘了 git的也忘了

好的是 之前用的登陆还在，修改IP直接登陆　然后

[root@localhost testuser]# passwd testuser
Changing password for user testuser.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
[root@localhost testuser]#

直接对应账号就行

然后发现gitlab密码也忘了　哎　．．．．

进入宿主
docker exec -it a63852603fac /bin/bash
vi /etc/gitlab/gitlab.rb

docker exec -it a63852603fac /bin/bash
------------------重置docker的gitlab密码---------------------
su - git

gitlab-rails console production //容易报错
gitlab-rails console -e production // 等待一会儿加载OK

user = User.where(id:1).first
user.password = '123123'
user.password_confirmation = '123123'
user.save!
exit
-----------------------------------------

 ssh-keygen -t rsa -C “19@qq.com”

生成ｓｓｈ　把老的ｓｓｈ删掉

 把这个pub的内容粘贴进来。

现在基本就能正常使用GitLab啦。。。

-----------------------------------------------------------------------------------备份一个以防万一----------------------------------------------------------------------------------

备份时需要保持gitlab处于正常运行状态，直接执行进行备份

docker exec -it a63852603fac /bin/bash
gitlab-rake gitlab:backup:create

这个文件在docker里的如下目录
/var/opt/gitlab/backups/

docker cp 容器名要拷贝的文件在容器里面的路径       要拷贝到宿主机的相应路径 

docker cp gitlab:/var/opt/gitlab/backups/1606312481_2020_11_25_12.9.1_gitlab_backup.tar  /home/mrg/

将备份拷贝出来  https://www.cnblogs.com/anliven/p/11954964.html

---------------------------------------------------------------------------------------------

或者把这个容器打包镜像

https://www.cnblogs.com/pjcd-32718195/p/11762079.html

//制作镜像
sudo docker commit -m "gitlab20201125 " -a "gitlab" gitlab mrg/gitlab:v1
sudo docker save -o /home/mrg/gitlabv1.tar mrg/gitlab:v1

保存到对应目录

发送到目标机器 

 scp "/home/mrg/gitlabv1.tar" root@192.168.2.10:/home/

上一步不成功 需要两台机器都安装scp功能

yum install openssh-clients -y

 //直接还原

---------------------------------------------------------
docker load < gitlabv1.tar
