I cannot see any java configuration in any jenkins files. Any ideas?

Try fix it by using:
尝试使用以下方法修复它：
ln -s /opt/jdk/bin/java /usr/bin/java
The script file who service utility is using is probably /etc/init.d/jenkins You could edit this file too...
服务实用程序正在使用的脚本文件可能是 /etc/init.d/jenkins 您也可以编辑此文件...

Jenkins needs java to start and in your case in
/usr/bin/directoryjavais not available
Jenkins 需要 java 才能启动，在您的情况下，
/usr/bin/目录java不可用
If you go to /etc/init.d/and open jenkinsfile you will find:
如果你去/etc/init.d/打开jenkins文件，你会发现：
candidates="
/etc/alternatives/java
/usr/lib/jvm/java-1.6.0/bin/java
/usr/lib/jvm/jre-1.6.0/bin/java
/usr/lib/jvm/java-1.7.0/bin/java
/usr/lib/jvm/jre-1.7.0/bin/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/bin/java
"
These are the paths where jenkins looks for java, and in your case java was not present in any of the above paths.
这些是 jenkins 查找 java 的路径，在您的情况下，java 不存在于上述任何路径中。
So look for the path where you are having java and add that path in the above jenkins file.
因此，查找您拥有 java 的路径并将该路径添加到上面的 jenkins 文件中。
Since you are having java in /opt/jdk/bin, then add this in jenkinsfile:
既然你有 java in /opt/jdk/bin，那么在jenkins文件中添加这个：
candidates="
/opt/jdk/bin/java <----Add here
/etc/alternatives/java
/usr/lib/jvm/java-1.6.0/bin/java
/usr/lib/jvm/jre-1.6.0/bin/java
/usr/lib/jvm/java-1.7.0/bin/java
/usr/lib/jvm/jre-1.7.0/bin/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/bin/java
"
