場景
CentOS6中安裝并啟動Jenkins時提示:
Starting Jenkins Jenkins requires Java8 or later, but you are running 1.7.0
Jenkins啟動時提示:Starting Jenkins Jenkins requires Java8 or later, but you are running 1.7.0 實作
CentOS伺服器上本來是安裝的JDK1.7，後來又修改為1.8,并且環境變量也已修改。
但是Jenkins仍然找的的舊的1.7
首先檢視自己的jdk的位置
Jenkins啟動時提示:Starting Jenkins Jenkins requires Java8 or later, but you are running 1.7.0 修改Jenkins的配置
Jenkins啟動時提示:Starting Jenkins Jenkins requires Java8 or later, but you are running 1.7.0 可以看到Jenkins是從這些目錄依次往下去尋找的。
将上面自己的JDK1.8的目錄添加到最上面，儲存并退出。
再次啟動Jenkins，啟動成功。
Jenkins啟動時提示:Starting Jenkins Jenkins requires Java8 or later, but you are running 1.7.0
