Change JENKINS_AJP_PORT="8009"(OR whatever value) to JENKINS_AJP_PORT="-1"
将JENKINS_AJP_PORT="8009"（或任何值）更改为JENKINS_AJP_PORT="-1"
It will work for sure.
它肯定会起作用。

Just a hunch - RHEL/CentOS have file execution disabled on the /tmp directory by default.
只是预感 - 默认情况下，RHEL/CentOS 在 /tmp 目录上禁用文件执行。
Try:
尝试：
mount -o remount,exec /tmp
And then (re)start Jenkins.
然后（重新）启动詹金斯。
That enables binaries to be executed (also .so files to be loaded) from the /tmp/ directory, which it looks like this particular packaging of Jenkins requires in order to load some kind of JNI code. When I tried installing and running on CentOS 6.4 this was the only issue I had.
这使得可以从 /tmp/ 目录执行二进制文件（也可以加载 .so 文件），看起来这个特定的 Jenkins 打包需要加载某种 JNI 代码。当我尝试在 CentOS 6.4 上安装和运行时，这是我遇到的唯一问题。
If that works, then you can either set it so this happens by default at startup using the settings in /etc/fstab (workable but lowers security on your system), or try to hack the startup process of the install you've got (not recommended), or install it using Tomcat or other packaging that doesn't require file execution on the /tmp directory (recommended but more work).
如果可行，那么您可以设置它，以便在启动时使用 /etc/fstab 中的设置（可行但会降低系统的安全性）默认情况下发生这种情况，或者尝试破解您已经安装的启动过程（不推荐），或者使用 Tomcat 或其他不需要在 /tmp 目录上执行文件的包来安装它（推荐但更多工作）。

I was getting the same error, I could not restart the instance in any way.
我遇到了同样的错误，我无法以任何方式重新启动实例。
I did a "yum update" in the server and that fixed the problem.
我在服务器中进行了“yum update”并解决了问题。
- java version "1.7.0_55"
- Jenkins ver. 1.571
- java版本“1.7.0_55”
- 詹金斯版。1.571

Which swithced ownership from my user Jenkins runs as to "jenkins", chown'ing fixed the problem

Just experienced this problem with RHEL install. The fix for me was to explicitly set the JENKINS_JAVA_CMD configuration parameter.
刚刚在安装 RHEL 时遇到了这个问题。我的解决方法是显式设置 JENKINS_JAVA_CMD 配置参数。
E.g.
例如
sudo vim /etc/sysconfig/jenkins
update:
JENKINS_JAVA_CMD=""
to:
JENKINS_JAVA_CMD="/usr/java/default/bin/java"

The following helped me:
以下帮助了我：
some time there will be stale some jenkins processes, so ps -ef | grep jenkins kill all of them and restart as above it will be clean.
有一段时间会有一些 jenkins 进程过时，所以 ps -ef | grep jenkins 杀死所有这些并重新启动如上它会是干净的。
ps -ef | grep jenkins
sudo kill -kill <pid>

Usually the tomcat service is taking over the 8080 port. Try to stop the tomcat service and rerun the jenkins service.
通常tomcat服务在接管8080端口。尝试停止tomcat服务并重新运行jenkins服务。

service jenkins start
服务詹金斯开始

for the above error i managed to go to /var/run/jenkins.pid and removed an already existing processing ID.
