Mac OS X上的Jenkins運行緩慢且崩潰

Question

我已經在舊版Mac Mini（2006）上安裝了Jenkins，當我通過以下方式啟動它時：

sudo launchctl load /Library/LaunchDaemons/org.jenkins-ci.plist

它會啟動並運行，但是一段時間后它將停止工作（這意味着瀏覽器只會給我一個空白的空白屏幕）

但是，當我嘗試通過此命令（從/ Applications / Jenkins）運行它時：

 java -jar jenkins.war

然后我在終端中收到此錯誤：

我認為Mac Mini可能沒有最佳硬件，但不確定。 我嘗試在詹金斯（Jenkins）中增加heapSize，但這似乎也無濟於事。

Mac Mini規格為：

Mac OS X 10.6.8 2 GHz Intel Core 2 Duo 2 GB 667 MHz DDR2 SDRAM

有人知道Jenkins為何如此緩慢並崩潰嗎？

Answer 1

我們在類似的硬件上運行Jenkins，這根本不是問題。

這似乎是一個錯誤，因為已將另一個進程綁定到端口8080，並且很有可能這可能是您先前啟動的jenkins的實例。 如果不是，請檢查是否有其他進程尚未占用此端口。

嘗試將localhost:8080放入瀏覽器中，以檢查Jenkins是否已在運行。 或者，嘗試在終端中運行lsof -i:8080 ，以查看可能還會綁定的內容。
