Gitlab迁移(亲测)
阅读原文时间:2023年07月08日阅读:3

当前gitlab部署在k8s内,根据基础设施设计此处不合理,需将gitlab迁移至主机部署的gitlab

当前位置:k8s 集群

迁移后位置:云主机部署gitlab

Gitlab Kubernetes: GitLab-CE 14.2.3

Gitlab Host : GitLab-CE 14.2.3

2.1 备份恢复过程

旧服务备份数据

备份命令:

gitlab-rake gitlab:backup:create

生成备份文件/opt/gitlab/backups/1547087542_2022_09_02_13.12.15_gitlab_backup.tar

新服务器准备工作

1. 安装gitlab-ce(保证两个服务器的gitlab版本一致)

2. 修改配置文件

```

vim /etc/gitlab/gitlab.rb

external_url 'https://gitlab.xxx.work'

##配置https

   nginx['enable'] = true

   nginx['redirect_http_to_https'] = true #http重定向到https

   nginx['ssl_certificate'] = "/opt/gitlab/ssl/zzz.zzz.crt" #ssl证书路径

   nginx['ssl_certificate_key'] = "/opt/gitlab/ssl/zzz.zzz.key" #ssl秘钥路径

  ##配置LDAP

  gitlab_rails['ldap_enabled'] = true

  gitlab_rails['prevent_ldap_sign_in'] = false

  gitlab_rails['ldap_servers'] = {

  'main' => {

  'label' => 'LDAP',

  'host' => 'xxx.xxx.xxx.xxx',

   'port' => 389,

  'uid' => 'sAMAccountName',

   'bind_dn' => 'CN=gitlab,CN=Users,DC=xxx,DC=com',

  'password' => 'xxxx',

  'active_directory' => true,

  'allow_username_or_email_login' => true,

  'block_auto_created_users' => false,

  'base' => 'DC=xxx,DC=com',

  'user_filter' => ''

  }

  }

##配置好以上信息后执行重置命令并重启

gitlab-ctl reconfigure

gitlab-ctl restart

3. 将备份文件放到本地

/opt/gitlab/backups/

4. 修改备份文件权限

chmod 777 /opt/gitlab/backups/1547087542_2022_09_02_13.12.15_gitlab_backup.tar

5. 停止unicorn和sidekiq服务

gitlab-ctl stop unicorn

gitlab-ctl stop sidekiq

6. 恢复备份数据

gitlab-rake gitlab:backup:restore BACKUP=1547087542_2022_09_02_13.12.15

7. 重启gitlab服务

gitlab-ctl start

2.2恢复过程中遇到错误解决

错误 一:监听问题

Restoring PostgreSQL database gitlabhq_production … ERROR: must be owner of extension pg_trgm
ERROR: must be owner of extension btree_gist
ERROR: must be owner of extension btree_gist
ERROR: must be owner of extension pg_trgm

解决:

vim /var/opt/gitlab/postgresql/data/postgresql.conf
listen_addresses = '*'

最下面新增两行

$ vim /var/opt/gitlab/postgresql/data/pg_hba.conf
local all all trust
host all all 127.0.0.1/32 trust

错误 二:用户问题

psql not ‘postgres’ superuser
解决:

$ su - gitlab-psql
$ /opt/gitlab/embedded/bin/psql -h 127.0.0.1 gitlabhq_production
psql (9.2.8)
Type "help" for help.

gitlabhq_production=# ALTER USER gitlab WITH SUPERUSER;
ALTER ROLE
gitlabhq_production=# CREATE USER postgres SUPERUSER;
gitlabhq_production=# \q

错误三:恢复后遇到500问题

问题描述:直接将备份恢复后,在页面上随便都会报500错误,日志提示'Object Storage is not enabled',需要按下文开启lfs功能再恢复数据

}

错误四:其他密钥问题

问题描述

gitlab代码仓库迁移数据后,在测试的时候发现有的功能按键点击出现500的错误,经过查资料解决了问题。现在把解决步骤整理一下

1.覆盖原来的gitlab的db_key_base到新的gitlab,db_key_base的位置在/etc/gitlab/gitlab-secrets.json

2.不同版本执行命令不同

CE版本执行

sudo gitlab-rails runner "Project.where.not(import_url: nil).each { |p| p.import_data.destroy if p.import_data }"

EE版本执行

sudo gitlab-rails runner "Project.where(mirror: false).where.not(import_url: nil).each { |p| p.import_data.destroy if p.import_data }"

执行完重启gitlab:gitlab-ctl restart

3.如果执行第二步没有生效,可以尝试如下操作

覆盖老的gitlab的secrets.yaml文件到新gitlab仓库的secrets.yaml 文件,文件的位置在:

/opt/gitlab/embedded/service/gitlab-rails/config/secrets.yaml

重启gitlab后发现之前500的页面可以正常访问了
