Beta Cluster/zh

Beta Cluster是Cloud VPS中一個功能性的，類似生产环境的地方，用於新功能的最後階段測試. 它在git master上運行，其MediaWiki核心和擴展代碼大約每十分鐘更新一次. Beta Cluster是维基媒体測試維基的一部分. 它使用自己的SUL登錄（與生產环境分開）. 例如，en.wikipedia.beta.wmflabs.org 帳戶也適用於 en.wikisource.beta.wmflabs.org，但不適用於任何生產环境的维基站点（如 en.wikipedia.org）.


 * 請參閱其配置概述.

基本原理
The aim is to provide an exact copy of the WMF production cluster (including db hosts, apaches, logging, squids, varnish caching, image scalers, etc.) using Cloud VPS instances.

打開的任務
See the workboard in Phabricator.

测试Beta集群上的更改
請參閱 部署到 Beta 版群集，瞭解部署步驟.

來自 beta 集群的日誌將發送到 Logstash，價格為 [beta-logs.wmcloud.org logstash-beta.wmflabs.org]. This site is currently password-protected, for an account look in:  .  If for some reason your EventLogging events aren't showing up in the dashboard, maybe [[wikitech:Analytics/Systems/EventLogging/TestingOnBetaCluster#How_to_verify_events|try the logs and database]].  If that's not working, maybe eventlogging and / or the machine needs to be rebooted.  Ping the folks in #wmf-analytics.

If you need to run a maintenance script on the Beta Cluster, ssh to deployment-deploy03.deployment-prep.eqiad.wmflabs (proxying through bastion.wmflabs.org).

If you need to check the databases, they're hosted on machines with the name *dbXX* among the ones listed here: https://openstack-browser.toolforge.org/project/deployment-prep.

If you just need to run some queries, ssh to deployment-deploy03.eqiad.wmflabs and run  or with any other dbname you need.

Stash messages to the beta cluster's server admin log by using the prefix "!log " in #wikimedia-releng.
