我正在使用以下指南将 Gitlab 服务器迁移到 Omnibus 版本：http: //theterminallife.com/migrating-gitlab-to-gitlab-omnibus/

一切正常，直到备份还原时的 rake 脚本，我在反引号上遇到几个语法错误。

@GitLabVM:~$ sudo gitlab-rake gitlab:backup:restore BACKUP=1452260428
Unpacking backup ... done
Restoring database ...

                    ^

LINE 1: UNLOCK TABLES;
        ^

LINE 1: DROP TABLE IF EXISTS `audit_events`;

我检查了 sql 文件，它没有我收到错误的反引号。

-- Converted by db_converter
START TRANSACTION;
SET standard_conforming_strings=off;
SET escape_string_warning=off;
SET CONSTRAINTS ALL DEFERRED;

DROP TABLE IF EXISTS "abuse_reports";
CREATE TABLE "abuse_reports" (
    "id" integer NOT NULL,
    "reporter_id" integer DEFAULT NULL,
    "user_id" integer DEFAULT NULL,
    "message" text ,
    "created_at" timestamp with time zone DEFAULT NULL,
    "updated_at" timestamp with time zone DEFAULT NULL,
    PRIMARY KEY ("id")
);

DROP TABLE IF EXISTS "application_settings";
CREATE TABLE "application_settings" (
    "id" integer NOT NULL,
    "default_projects_limit" integer DEFAULT NULL,
    "signup_enabled" int4 DEFAULT NULL,
    "signin_enabled" int4 DEFAULT NULL,
    "gravatar_enabled" int4 DEFAULT NULL,
.....
.....

Gitlab 中有一个相关的错误报告，但它已被弃用，我似乎无法找到此错误发生的位置。我将不胜感激任何帮助追踪这一点。谢谢你。

这通常发生在从 MySQL 数据库创建转储时以及在恢复过程中 Postgress db 收到这些语法错误

您可以创建一个与 PostgreSQL 兼容的单独数据库转储，然后只需按照以下步骤操作。

sudo -u git -H mysqldump --compatible=postgresql--default-character-set=utf8 -r gitlabhq_production.mysql -u root gitlabhq_production -p

# Clone the database converter
sudo -u git -H git clone https://github.com/gitlabhq/mysql-postgresql-converter.git -b gitlab

# Convert gitlabhq_production.mysql
sudo -u git -H mkdir db
sudo -u git -H python mysql-postgresql-converter/db_converter.py gitlabhq_production.mysql db/database.sql
sudo -u git -H ed -s db/database.sql < mysql-postgresql-converter/move_drop_indexes.ed

# Compress database backup
# Warning: If you have Gitlab 7.12.0 or older skip this step and import the database.sql directly into the backup with:
# sudo -u git -H tar rf TIMESTAMP_gitlab_backup.tar db/database.sql
# The compressed databasedump is not supported at 7.12.0 and older.
sudo -u git -H gzip db/database.sql

# Replace the MySQL dump in TIMESTAMP_gitlab_backup.tar.

# Warning: if you forget to replace TIMESTAMP below, tar will create a new file
# 'TIMESTAMP_gitlab_backup.tar' without giving an error.

sudo -u git -H tar rf TIMESTAMP_gitlab_backup.tar db/database.sql.gz

# Done! TIMESTAMP_gitlab_backup.tar can now be restored into a Postgres GitLab
# installation.
# See https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/raketasks/backup_restore.md for more information about backups.
