Install jenkins under centos6.5

Install jenkins under centos6.5

The predecessor of Jenkins is Hudson, a scalable continuous integration engine.

In general, jenkins is a plug-in that can be deployed automatically,

For me, the application is also deployed on the system.

Go to our installation steps.

1. Install JDK and build a maven Environment

Considering the actual application scenarios of jenkins, we need to install these basic environments first.

Jdk installation is relatively simple and I will not go into details here. The maven environment borrowed the content of other osc heroes blogs,

The installation is successful.

Maven official website download installation package: http://maven.apache.org/download.cgi

Download the version as needed. Here, the author chooses version 3.1.1.

1. Upload apache-maven-3.1.1-bin.tar.gz to the server,

Decompress:

Tar-zvxfapache-maven-3.1.1-bin.tar.gz

Move to/usr/local:

mvapache-maven-3.1.1/usr/local

Configure Environment Variables

vi/etc/profile

Add

exportMAVEN_HOME=/usr/local/apache-maven-3.1.1

exportPATH=$PATH:$MAVEN_HOME/bin

Recompile the file

source/etc/profile

Verify that maven is successfully installed

mvn--version

The console displays the following information:

Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 23:22:22 + 0800)

Maven home:/usr/local/apache-maven-3.1.1

Java version: 1.7.0 _ 25, vendor: Oracle Corporation

Java home:/usr/java/jdk1.7.0 _ 25/jre

Default locale: zh_CN, platform encoding: UTF-8

OS name: "linux", version: "2.6.32-358.6.2.el6.x86 _ 64", arch: "amd64", family: "unix"

Indicates that the installation is successful.

2. Install jenkins

wget-O/etc/yum.repos.d/jenkins.repohttp://pkg.jenkins-ci.org/redhat/jenkins.reporpm--importhttp://pkg.jenkins-ci.org/redhat/jenkins-ci.org.keyyuminstalljenkins

After a command is executed, jenkins is installed, which is very simple.

Configure the jenkins port to avoid conflict.

vi/etc/sysconfig/jenkins

Enter this file. This is the jenkins system configuration file,

Locate 2 and modify the port number:

JENKINS_PORT = "8080"

JENKINS_AJP_PORT = "8009"

The default value is as follows. You can change it to the desired port number to avoid conflict (the default tomcat port is also like this)

Here, the author changes:

JENKINS_PORT = "8888"

JENKINS_AJP_PORT = "8889"

Next we can try to start the jenkins service.

Servicejenkinsstart

If the prompt is: Starting Jenkins [OK]

The jenkins service is successfully started. You can directly access jenkins through http: // ip: port number.

However, the following error is reported:

StartingJenkinsbash:/usr/bin/java: The file or directory does not exist.[Failed]

If this error occurs, you do not need to worry about it. The cause of this error is your jdk configuration error,

Run the following command:

Java-version

Java version "1.7.0 _ 25"

Java (TM) SE Runtime Environment (build 1.7.0 _ 25-b15)

Java HotSpot (TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

We can see that the jdk version is1.7.0 _ 25, copy this name

vi/etc/init.d/jenkins

Find this code

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

We will find that this is not called1.7.0 _ 25 file directory

After this code, we add

/usr/java/jdk1.7.0_25/bin/java

The effect is as follows:

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/usr/java/jdk1.7.0_25/bin/java"

Save and exit. Run the following command again:

servicejenkinsstart

Is it successful?

Stop command:

servicejenkinsstop

Restart command:

servicejenkins restart

After successful startup, we can access the service through http: // ip: port number.

At this point, the jenkins installation is OK.
