Detailed steps for installing Jenkins under centos 7 system

This article mainly introduces the installation of Jenkins in centos 7 and related content, sharing for your reference and study, without saying much, let's start with a detailed introduction:

The installation

Add yum repos and install

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
sudo yum install jenkins

Install java if you do not have java

sudo yum install java

Start and stop

sudo service jenkins start/stop/restart
sudo chkconfig jenkins on

Default Settings for jenkins

The & # 8226; Jenkins starts when the system starts. Details refer to/etc/init d/jenkins

The & # 8226; Jenkins creates a user called jenkins. If you modify user, you modify the user: /var/log/jenkins, /var/lib/jenkins, /var/cache/jenkins

The & # 8226; If you encounter problems, see the log/var log/jenkins/jenkins log

The & # 8226; Configuration file /etc/sysconfig/jenkins

The & # 8226; 8080 is enabled by default

Turn on and off the firewall

firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --reload

firewall-cmd --list-all

About java on centos

Jenkins does not support working on centos's default jdk. remove is required if shown below:

java -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.6 20110731 (Red Hat 4.4.6-3)

To use Jenkins correctly:

yum remove java

You can then install openjdk

yum install java-1.7.0-openjdk

Correct as follows:

java -version
java version "1.7.0_79"
OpenJDK Runtime Environment (rhel-2.5.5.1.el6_6-x86_64 u79-b14)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

Configure port

Modify/etc/sysconfig/jenkins:

JENKINS_PORT="8080"

Configure the java path

Direct startup:

sudo yum install java

0

However, we found that the startup failed, so we need to configure the java location:

sudo yum install java

1

At startup join the machine java:

sudo yum install java

2

I added the last line above.

Restart and it will run normally.

--------------------------------------------------------------------------------

Start the

When the browser enters ip and port access, the first page is being started. After the startup, a series of passwords will be entered, and then the plug-in installation interface will be entered and the default will be selected. At this time, an error will be reported:

An error occurred during installation: Forbidden

Solutions:

I "fixed it" by restarting Jenkins http: / / localhost: 8080 / restart. Restart and you can continue.
