Jenkins 無法啟動

Question

我正在嘗試啟動並收到以下錯誤

root@ip-172-31-80-112 ~]# systemctl start jenkins

Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details



[root@ip-172-31-80-112 ~]# systemctl status jenkins

這是在我的 /etc/init.d/jenkins

誰能幫我解決這個問題。 先感謝您。 似乎是 Jenkins 無法在我的服務器上找到我的 java 版本，可能是一些鏈接指向了錯誤的位置

Answer 1

您的機器上似乎有多個 java 版本可用。 您可以通過簡單地運行 sudo update-alternatives --config java 來更新正確的版本以避免 jenkins 和 java 版本不匹配嗎？

另請參閱： Jenkins 在運行“service start jenkins”時失敗

Answer 2

根據 Jenkins 版本，錯誤不是很清楚，但確保 Jenkins>=2.357 使用的是 Java 11 安裝，而不是 Java 8 安裝。

Answer 3

我剛剛解決了我的，這與這篇文章的問題類似。

只是一些背景故事：我嘗試在我的 Ubuntu 22.10 上安裝 Jenkins 三 (3) 次，一切順利。 但都未能啟動。

我使用的最后一個安裝說明來自此鏈接： https://community.jenkins.io/t/ubuntu-20-04-initial-jenkins-startup-failure/1419

-- Mark Waite 先生的回答 -- Jenkins 治理委員會。

基本上：

$ sudo apt-get install openjdk-11-jdk-headless
$ curl -fsSL https://pkg.jenkins.io/debian/jenkins.io.key | sudo tee /usr/share/keyrings/jenkins-keyring.asc > /dev/null
$ echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian binary/ | sudo tee /etc/apt/sources.list.d/jenkins.list > /dev/null
$ sudo apt-get update
$ sudo apt-get install jenkins

然后它失敗了：

...

谷歌搜索沒有給我任何答案。 如此隨意，我試過：

/usr/bin/jenkins

output很長，我把相關的轉一下：

...

...

我忘記了我已經為 Apache2 設置了端口8080。我剛剛停止並禁用了 Apache2，然后使用以下命令啟動 Jenkins：

$ systemctl start jenkins.service

它現在正在運行。 我希望這對您有所幫助，盡管您的情況可能並非如此。
