Git configured for git user? ... yes Has python2? ... yes python2 is supported version? ... yes Checking Environment ... Finished Checking GitLab Shell ... GitLab Shell version? ... OK (1.2.0) Repo base directory exists? ... yes Repo base directory is a symlink? ... no Repo base owned by git:git? ... yes Repo base access is drwxrws---? ... yes post-receive hook up-to-date? ... yes post-receive hooks in repos are links: ... yes Checking GitLab Shell ... Finished Checking Sidekiq ... Running? ... yes Checking Sidekiq ... Finished Checking GitLab ... Database config exists? ... yes Database is SQLite ... no All migrations up? ... yes GitLab config exists? ... yes GitLab config outdated? ... no Log directory writable? ... yes Tmp directory writable? ... yes Init script exists? ... yes Init script up-to-date? ... yes Redis version >= 2.0.0? ... yes Checking GitLab ... Finished ``` ## Rebuild authorized_keys file[](#rebuild-authorized_keys-file "Permalink") 在某些情况下，有必要重建`authorized_keys`文件. 为此，请运行： **全部安装** ``` sudo gitlab-rake gitlab:shell:setup ``` **源安装** ``` cd /home/git/gitlab sudo -u git -H bundle exec rake gitlab:shell:setup RAILS_ENV=production ``` 输出示例： ``` This will rebuild an authorized_keys file. You will lose any data stored in authorized_keys file. Do you want to continue (yes/no)? yes ``` ## Clear Redis cache[](#clear-redis-cache "Permalink") 如果出于某种原因，仪表板显示了错误的信息，则可能需要清除 Redis 的缓存. 为此，请运行： **全部安装** ``` sudo gitlab-rake cache:clear ``` **源安装** ``` cd /home/git/gitlab sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production ``` ## Precompile the assets[](#precompile-the-assets "Permalink") 有时，在版本升级期间，您可能会遇到一些错误的 CSS 或缺少某些图标的情况. 在这种情况下，请尝试再次重新编译资产. 这仅适用于源安装，不适用于 Omnibus 软件包. **源安装** ``` cd /home/git/gitlab sudo -u git -H bundle exec rake gitlab:assets:compile RAILS_ENV=production ``` 对于多功能版本，未优化的资产（JavaScript，CSS）在上游 GitLab 发行时被冻结. 多功能版本包括这些资产的优化版本. 除非在安装软件包之后在生产机器上修改 JavaScript / CSS 代码，否则应该没有理由在生产机器上重做`rake gitlab:assets:compile` . 如果您怀疑资产已损坏，则应重新安装 omnibus 软件包. ## Check TCP connectivity to a remote site[](#check-tcp-connectivity-to-a-remote-site "Permalink") 有时您需要知道您的 GitLab 安装是否可以连接到另一台机器上的 TCP 服务-也许是 PostgreSQL 或 HTTPS 服务器. 包含一个 Rake 任务可以帮助您： **全部安装** ``` sudo gitlab-rake gitlab:tcp_check[example.com,80] ``` **源安装** ``` cd /home/git/gitlab sudo -u git -H bundle exec rake gitlab:tcp_check[example.com,80] RAILS_ENV=production ``` ## Clear exclusive lease (DANGER)[](#clear-exclusive-lease-danger "Permalink") GitLab 使用共享锁机制： `ExclusiveLease`防止共享资源中的同时操作. 一个示例是在存储库上运行定期垃圾收集. 在非常特殊的情况下，如果不释放锁定，则由专有租赁锁定的操作可能会失败. 如果您不能等待它过期，可以运行此任务以手动清除它. 要清除所有专有租赁： **危险：**请勿在 GitLab 或 Sidekiq 运行时运行它 ``` sudo gitlab-rake gitlab:exclusive_lease:clear ``` 要指定租约`type`或租约`type + id` ，请指定范围： ``` # to clear all leases for repository garbage collection: sudo gitlab-rake gitlab:exclusive_lease:clear[project_housekeeping:*] # to clear a lease for repository garbage collection in a specific project: (id=4) sudo gitlab-rake gitlab:exclusive_lease:clear[project_housekeeping:4] ``` ## Display status of database migrations[](#display-status-of-database-migrations "Permalink") 请参阅[升级文档](../../update/README.html#checking-for-background-migrations-before-upgrading) ，以了解在升级 GitLab 时如何检查迁移是否完成. 要检查特定迁移的状态，可以使用以下 Rake 任务： ``` sudo gitlab-rake db:migrate:status ``` 这将为每个迁移 ID 输出一个`Status`为`up`或`down`的表. ``` database: gitlabhq_production Status Migration ID Migration Name -------------------------------------------------- up migration_id migration_name ``` ## Run incomplete database migrations[](#run-incomplete-database-migrations "Permalink") 数据库迁移可能会停留在不完整的状态. 也就是说，它们在`sudo gitlab-rake db:migrate:status`命令的输出中将处于`down`状态. 要完成这些迁移，请使用以下 Rake 任务： ``` sudo gitlab-rake db:migrate ``` 命令完成后，运行`sudo gitlab-rake db:migrate:status`来检查是否所有迁移都已完成（具有`up`状态）. ## Import common metrics[](#import-common-metrics "Permalink") 有时，您可能需要重新导入为"指标"仪表板提供动力的通用指标. 这可能是由于[更新现有指标](../../development/prometheus_metrics.html#update-existing-metrics)或作为[故障排除措施的结果](../../operations/metrics/dashboards/index.html#troubleshooting) . 要重新导入指标，可以运行： ``` sudo gitlab-rake metrics:setup_common_metrics ```
