由于服务器到期等因素，需要对 GitLab 进行迁移，在此记下一段历程。

首先要保证迁入和迁出 GitLab 的版本是一致的，使用这一条指令：

cat /opt/gitlab/embedded/service/gitlab-rails/VERSION

我的两个服务器输出分别是：

# 迁入服务器
$ cat /opt/gitlab/embedded/service/gitlab-rails/VERSION
12.7.5-ee
# 迁出服务器
$ cat /opt/gitlab/embedded/service/gitlab-rails/VERSION
12.5.2-ee

升级 GitLab

因此需要对服务器进行升级。

我采用的安装方法是 Omnibus, 采用官网推荐的方式进行升级：

# Debian/Ubuntu
sudo apt-get update
sudo apt-get install gitlab-ce

# Centos/RHEL
sudo yum install gitlab-ce

# 如果是 ee就修改为 ee

其他升级方式可以来这里看：Updating GitLab installed with the Omnibus GitLab package

打备份包

我采用的安装方法是 Omnibus, 采用官网推荐的方式进行打包：Creating a backup of the GitLab system

完成后就已经对 GitLab 整个系统备份到 /var/opt/gitlab/backups，根据官网除了打包还需要备份以下两个文件：

/etc/gitlab/gitlab-secrets.json
/etc/gitlab/gitlab.rb

因此将这个两个文件也拷入 backups 文件夹，以便后面打包迁移：

cp /etc/gitlab/gitlab-secrets.json /var/opt/gitlab/backups/gitlab-secrets.json
cp /etc/gitlab/gitlab.rb /var/opt/gitlab/backups/gitlab.rb

完成后看一下 /var/opt/gitlab/backups 文件夹中就是我们需要迁移走的所有文件啦

$ ls
1580984631_2020_02_06_12.7.5-ee_gitlab_backup.tar  gitlab.rb  gitlab-secrets.json

对它进行打包：

# 打包后，以 gzip 压缩
$ tar -zcvf /tmp/gitlab.2020.2.6.backups.tar.gz /var/opt/gitlab/backups
tar: Removing leading `/' from member names
/var/opt/gitlab/backups/
/var/opt/gitlab/backups/gitlab.rb
/var/opt/gitlab/backups/1580984631_2020_02_06_12.7.5-ee_gitlab_backup.tar
/var/opt/gitlab/backups/gitlab-secrets.json

安装阿里云 ossutils 工具

在这里使用阿里云 oss 做中转，你也可使用其他方式将压缩包传入待转入服务器。

首先安装：

# 下载工具：
$ wget http://gosspublic.alicdn.com/ossutil/1.6.10/ossutil64                           

# 修改文件执行权限：
$ chmod 755 ossutil64

# 使用交互式配置生成配置文件：
$ ./ossutil64 config
请输入配置文件名，文件名可以带路径（默认为：/home/user/.ossutilconfig，回车将使用默认路径。如果用户设置为其它路径，在使用命令时需要将--config-file选项设置为该路径）：
未输入配置文件路径，将使用默认配置文件：/home/user/.ossutilconfig。
对于下述配置，回车将跳过相关配置项的设置，配置项的具体含义，请使用"help config"命令查看。
请输入endpoint：http://oss-cn-shenzhen.aliyuncs.com
请输入accessKeyID：yourAccessKeyID
请输入accessKeySecret：yourAccessKeySecret
请输入stsToken：

使用命令查看 endpoint,

$ ./ossutil64 ls

0.298487(s) elapsed

上传

$ ./ossutil64 cp /tmp/gitlab.2020.2.6.backups.tar.gz oss://frytea-temporary/gitlab/
Succeed: Total num: 1, size: 558,098,855. OK num: 1(upload 1 files).                                        

150.496710(s) elapsed

接下来来到待迁入服务器，同样执行 安装 之后进行下载：

$ ./ossutil64 cp oss://frytea-temporary/gitlab/gitlab.2020.2.6.backups.tar.gz ~
Succeed: Total num: 1, size: 558,098,855. OK num: 1(download 1 objects).                                     

10.706132(s) elapsed

在这类迁入服务器是阿里云服务器，因此下载速度很快。

还原备份

首先将下载好的文件夹解压：

$ tar -zxvf gitlab.2020.2.6.backups.tar.gz
var/opt/gitlab/backups/
var/opt/gitlab/backups/gitlab.rb
var/opt/gitlab/backups/1580984631_2020_02_06_12.7.5-ee_gitlab_backup.tar
var/opt/gitlab/backups/gitlab-secrets.json

压缩时保留了原有目录结构。

将备份文件拷入迁入服务器的 /var/opt/gitlab/backups/ 文件夹：

mv ~/var/opt/gitlab/backups/1580984631_2020_02_06_12.7.5-ee_gitlab_backup.tar /var/opt/gitlab/backups/

恢复备份：

$ sudo gitlab-backup restore BACKUP=1580984631_2020_02_06_12.7.5-ee
# 这里去掉备份名字的_gitlab_backup.tar
# 以下是输出

mv ~/var/opt/gitlab/backups/gitlab.rb /etc/gitlab/gitlab.rb

重启 GitLab

sudo gitlab-ctl reconfigure
sudo gitlab-ctl restart
sudo gitlab-rake gitlab:check SANITIZE=true

完成！
