java - Mac OS X 上的 Jenkins 速度缓慢并且崩溃

Question

我在旧的 Mac Mini (2006) 上安装了 Jenkins，当我通过以下方式启动它时:

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

它启动并运行，但一段时间后它停止工作(这意味着浏览器只会给我一个空白的白色屏幕)

但是当我尝试通过此命令(来自/Applications/Jenkins)运行它时:

 java -jar jenkins.war

然后我在终端中收到此错误:

我认为 Mac Mini 可能没有最佳的硬件，但不确定。我尝试增加 Jenkins 中的堆大小，但这似乎也没有帮助。

Mac Mini 规范为:

Mac OS X 10.6.82 GHz 英特尔酷睿 2 双核2 GB 667 MHz DDR2 SDRAM

有人知道为什么 Jenkins 这么慢并且崩溃吗？

Answer 1

我们在类似的硬件上运行 Jenkins，这根本不应该是问题。

这看起来是另一个进程已经绑定(bind)到端口 8080 的错误，并且很有可能这可能是您之前启动的 jenkins 实例。如果没有，请检查是否有任何其他进程尚未占用此端口。

尝试将 localhost:8080 放入浏览器中以检查 Jenkins 是否已在运行。或者尝试在终端中运行 lsof -i:8080 来查看还可能绑定(bind)的内容。
