將請求重定向到羣集中的另一臺服務器

2016-12-14 93 views

我已經在單臺機器上設置了具有2個節點的垂直羣集。我還將Apache Web Server配置到節點/服務器/集羣成員。我還通過在網絡服務器中設置IgnoreAffinityRequests=false來啓用Session Affinity。例如，我使用集羣成員1登錄，然後如果該成員/服務器失敗，我需要WebSphere Application Server Network Deployment將使用會話的請求重定向到另一個可用服務器。我怎樣才能做到這一點？將請求重定向到羣集中的另一臺服務器

以下是我的plugin-cfg.xml的webserver01

如果JVM的響應過程中具有親和力下降，或變得無法訪問，或者返回一個HTTP 503，WAS WebServer Plugin會將後續請求發送給其他JVM。

如果您配置否定的ServerIOTimeout，並且響應超時，親和力也將被破壞。

「失敗」的JVM無法將工作發送給其他JVM本身。

對於這兩個Web服務器，「ServerIOTimeout」均爲60。 –
