该错误主要原因就是找不到java的bin文件
10月 19 15:54:47 newings jenkins[43402]: ERROR: No Java executable found in current PATH: /bin:/usr/bin:/sbin:/usr/sbin
部分网上资料是这样操作的，编辑vim /etc/init.d/jenkins插入如下内容
vim /etc/init.d/jenkins /usr/local/jdk1.8.0_151/bin/java
这样的方法试过了，没起任何作用，不知道是我的插入的地方不对还是怎么了。反正错误依旧还在。
这样不行的话，就只能试试软连接看看能不能用
ln -s /usr/jdk1.8.0_131/bin/java /usr/bin/java
然后卸载Jenkins，再次安装就正常了
