无法将詹金斯升级到最新版本答案

【问题标题】：Not able to upgrade jenkins to the latest version无法将詹金斯升级到最新版本

【问题描述】：

我在自己的 Linux 容器中运行 Jenkins 1.6.43。我想升级到最新的 2.7 版本。发行说明说我所要做的就是下载最新的 Jenkins，删除固定的插件并重新启动。

我也这样做了——停止当前的 jenkins，使用 wget 下载，删除所有固定的插件，然后启动它。我收到"started jenkins - ok"，但什么也没发生。我没有看到任何进程正在运行！我用 2.6 和 2.7 版本尝试过这个，我看到了相同的结果！如果我恢复到之前的 1.643 战争并重新启动，我看不到任何进程正在运行。

有人可以帮忙！！！如何解决这个问题？

【问题讨论】：

在 /etc/sysconfig/jenkins 中设置 JENKINS_AJP_PORT="-1" 解决了问题，我可以成功启动 Jenkins 并登录，但日志文件中还有其他严重错误
