jenkins安装错误

[root@docker2 init.d]# ./jenkins start
Starting Jenkins Running with Java 8 from /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.362.b08-1.el7_9.x86_64/jre, which is older than the minimum required version (Java 11).
Supported Java versions are: [11, 17]

我升级了jdk版本 yum install java-11-openjdk-devel

之后重新安装jenkins 报错：
[root@docker2 init.d]# ./jenkins status
jenkins 已死，但 pid 文件存在

请问这是什么原因呢？
