Facing issue with starting the Jenkins instance.. here is the log,
I am using 1.542 (also tried with previous releases but no success)
Anybody is facing this kind of issue?
It looked very similar to https://issues.jenkins-ci.org/browse/JENKINS-20609 but not sure if thats the case

Running on FreeBSD on OpenJDK7, I was missing package x11-fonts/fontconfig.
Installing it fixed the problem.
This other thread helped:
Headless continuous integration with Jenkins
You should try this java argument on your start:
-Djava.awt.headless=true
Seems similar to the font problem shown at: https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+got+java.awt.headless+problem
For me -Djava.awt.headless=true didn't help at all. In fact, it's already specified in the Fedora default config. For me it missed the fontconfig package.
yum install fontconfig
And voila, it worked.
Details: http://vault-tec.info/post/98877792626/jenkins-service-unavailable
I had similar problem on RedHat 6 after upgrading Open JDK. Running the following fixed the problem.
yum install dejavu-fonts dejavu-lgc-sans-mono-fonts dejavu-sans-fonts dejavu-sans-mono-fonts dejavu-serif-fonts

Can you please check in the processes if any other instance of Jenkins is running, also if there are any, please kill all of them start command prompt in admin mode and then try executing command again.
You can also check if the port is being occupied by some other process.
The Jenkins installation seems like it went fine but when I launch the localhost:8080, Jenkins is asking for password. However, I am not able to find the initialAdminPassword file in my system. I checked it multiple times; it seems that this file does not exist. Therefore, what is the issue and how do I get the initial Jenkins login password?

I was having a similar problem on windows where the folder was missing.
I went to C:\Program Files\Jenkins and opened jenkins.err.log
It had the key that I needed to proceed.
If you are unable to find the secret file, please uninstall and re-install Jenkins again. Else, delete the .jenkins folder in C:\Users\...\.jenkins\secrets.
===============
Are you using jenkins.war or jenkins.exe to install? If you are using jenkins.exe, try to download jenkins.war from Jenkins war.
Open Command Prompt, run java -jar jenkins.war.
Click on the images to see the oputput
Open browser with URL localhost:8080/
see the file "C:\Program Files\Jenkins\jenkins.err.log"
It has initialpassword before making entry into file.
It seems the issue is that the 8080 port is occupied, so i have used 8081 and its working good.
Check if another service is using port 8080. For me I had to stop the service which i dont really need at the moment and re-run java -jar jenkins.war. with this it created the secret folder where i found the default password
for me did not show the "secret" folder ,and didn't show the "config.xml" file too ,and inside the users folder too was not showing any thing that can help me, so i did the following steps:
i changed the port number from 8080 to 8085 from the "jenkins.xml"
(C:\Program Files (x86)\Jenkins)
restart the computer
after boot up with browser i tried to go "http://localhost:8085/"
then everything solved ,now is showing the starter page of jenkins and the secret folder is created inside the jenkins folder too.
give command sudo su to login as super user
change to secrets folder
cd secrets
cat initialAdminPassword
sometimes it's in C:\Windows\System32\config\systemprofile\AppData\Local\Jenkins\.jenkins\secrets, as I personally experienced.
This is shown as:
In my case, I was selected port which was already in use.
Reinstalling and configuring with different port fixed the issue.
If you're using Jenkins on Docker try using
docker exec -u 0 -it name_of_jenkins_container bash
or
docker exec -u 0 -it name_of_jenkins_container /bin/bash
it will login to this container as root user.
Am running Jenkins 1.6.43 in its own container in Linux. I want to upgrade to latest 2.7 version. The release notes say that all I have to do is download the latest Jenkins, remove the pinned plugins and restart.
I did the same- Stopped current jenkins,downloaded using wget, removed all pinned plugins and then started it. I get "started jenkins - ok", but nothing is happening. I do not see any process running! I tried this with 2.6 and 2.7 version and I see the same result! If I revert to my previous 1.643 war and restart also, I do not see any process running.
The log shows:

Can someone please help!!!How to fix this?
This helped me to solve this issue
setting up JENKINS_AJP_PORT="-1" in /etc/sysconfig/jenkins and then I restarted
I have installed Jenkins through installer. I'm getting below error when I'm executing jenkins.war file. I have closed XAMPP which was using 8080 port. Still showing this error. Can anyone suggest how to resolve this?

java -jar jenkins.war --httpPort=8081
Or any other port than default will solve the issue. Worked for me.
There's already some application binding port 8080.
As the log says:
WARNING: FAILED SelectChannelConnector#0.0.0.0:8080: java.net.BindException: Add
ress already in use: bind
java.net.BindException: Address already in use: bind
Try to check which application is using that port and shut it down, or alternatively, change Jenkins port on the Jenkins configuration.
I recently upgraded Jenkins from 1.506 to 1.515
After the upgrade, Jenkins doesn't seem to start. The logs are full of warnings like:
WARNING: Failed to load hudson.scm.Cvs...
java.lang.InstantiationException: file:/jenkins/plugins/cvs/WEB-INF/classes/META-INF/annotations/hudson.Extension might need to be rebuilt: java.lang.ClassNotFoundException: hudson.scm.Cvs...
And the web GUI is inaccessible (times out).
I have downgraded to 1.506 again, but same result.
Since all the log warnings are CVS related (which I don't use, we're on svn), I tried deleting
/jenkins/plugins/cvs
/jenkins/plugins/cvs.jpi
But they come back after each restart, along with all the warnings.
I am running jenkins as a war in a dedicated tomcat running on Solaris.
Right now, Jenkins is completely inaccessible. Any pointers appreciated!

WARNING: Failed to scout hudson.scm.cvstagging.LegacyTagAction$LegacyTagActionDescriptor
I resolved this by clearing the "Workspace Root Directory". That is:
Stopping Jenkins
Moving the workspace folder (mv JENKINS_HOME/workspace JENKINS_HOME/workspace-old)
Creating a new workspace (mkdir JENKINS_HOME/workspace)
Restarting Jenkins
I don't what became corrupted, or how, but this solution didn't seem to have any adverse affects.
According to the Jenkins config page (Jenkins > Manage Jenkins > Configure System > Click Advance button near Home directory) the Workspace Root Directory is used to "Specify where Jenkins would store job workspaces on the master node."
From what I could determine, it seems to just store the files checked out from svn for each job, which are obviously easily replaced.
Anyway, all working again now.
And the upgrade worked fine second time around.
