gitlab迁移

背景

之前gitlab在阿里云机部署，因为外网相对不安全考虑迁到内网

环境

gitlab-11.11.3 docker部署

实施

备份

docker exec -ti gitlab bashgitlab-rake gitlab:backup:createdocker cp gitlab:/var/opt/gitlab/backups/1612427334_2021_02_04_11.11.3_gitlab_backup.tar .

在内网机器启动相同版本gitlab（gitlab备份恢复需要相同版本)

docker exec -ti gitlab bashmv 1612427334_2021_02_04_11.11.3_gitlab_backup.tar /var/opt/gitlab/backups/chmod 755 /var/opt/gitlab/backups/1612427334_2021_02_04_11.11.3_gitlab_backup.tarchown root:root /var/opt/gitlab/backups/1612427334_2021_02_04_11.11.3_gitlab_backup.targitlab-rake gitlab:backup:restore BACKUP=1612427334_2021_02_04_11.11.3

问题

1.进入ci/cd runner页面报500

gitlab-rails consoleCi::Runner.all.update_all(token_encrypted: nil)gitlab-rails dbconsoleUPDATE projects SET runners_token = null, runners_token_encrypted = null;

2.新建用户，在强制用户修改密码时报500
log 显示类似: 因为没有第一时间写文章，日志显示类似，不是我遇到的日志。

The form contains the following error:    PG::NotNullViolation: ERROR: null value in column "id" violates not-null constraint DETAIL: Failing row contains (null, 164, t). : INSERT INTO "project_ci_cd_settings" ("project_id") VALUES (164) RETURNING "id"

解决思路：查看对应表有没有null值，启动全新的gitlab对比表结构

解决:

gitlabhq_production=> CREATE SEQUENCE user_preference_id_seq INCREMENT BY 1 NO MINVALUE NO MAXVALUE START WITH 106 OWNED BY user_preferences.id;   重新创建sequencegitlabhq_production=> ALTER TABLE user_preferences ALTER COLUMN id SET DEFAULT NEXTVAL('user_preference_id_seq'::regclass);                         恢复表结构修饰符

3.创建merge时指定给用户时，提交后500
gitlab日志:

==> /var/log/gitlab/postgresql/current <==2021-03-18_05:52:05.23424 ERROR:  null value in column "id" violates not-null constraint2021-03-18_05:52:05.23427 DETAIL:  Failing row contains (null, 61, 4046).2021-03-18_05:52:05.23427 STATEMENT:  INSERT INTO "merge_request_assignees" ("user_id", "merge_request_id") VALUES (61, 4046) RETURNING "id"

解决:

gitlabhq_production=> CREATE SEQUENCE merge_request_assignees_id_seq INCREMENT BY 1 NO MINVALUE NO MAXVALUE START WITH 106 OWNED BY merge_request_assignees.id;   重新创建sequencegitlabhq_production=> ALTER TABLE merge_request_assignees ALTER COLUMN id SET DEFAULT NEXTVAL('merge_request_assignees_id_seq'::regclass);                         恢复表结构修饰符

gitlab迁移及迁移后500问题

解决:

说明：迁移gitlab后会有数据库序列丢失问题，重建序列，并恢复字段修饰符。对比全新gitlab你会发现，可能会丢失很多seq，建议恢复所有。
