Simple setup steps for Jenkins under Linux environment

Brief introduction

Jenkins is an open source software project designed to provide an open and easy-to-use software platform that makes continuous software integration possible. This is a Java-based development tool.

For a variety of reasons, recently began to contact, decided to study. Jenkins more than one way to build, a personal summary of one of them, the content of the article is relatively simple, shortcomings, welcome correction.

The JDK should be needless to say, I'm sure you'll find it.

Maven http://maven.apache.org/download.cgi

Install the software as follows:

Jdk-8u131-linux-x64.tar.gz

Apache-maven-3.5.0-bin.tar.gz

Environment:

First, configure the JDK

[Email protected] jdk]# pwd
/data/jdk
[[email protected] jdk]# ls
Jdk-8u131-linux-x64.tar.gz

Unpack the JDK installation package:

[Email protected] jdk]# tar zxvf jdk-8u131-linux-x64.tar.gz
[[email protected] jdk]# ls
jdk1.8.0_131 jdk-8u131-linux-x64.tar.gz
[Email protected] jdk]# CD jdk1.8.0_131/

[Email protected] jdk1.8.0_131]# pwd
/data/jdk/jdk1.8.0_131

[[email protected] jdk1.8.0_131]# ls
Bin DB javafx-src.zip Lib man release Thirdpartylicensereadme-javafx.txt
COPYRIGHT include JRE LICENSE readme.html src.zip THIRDPARTYLICENSEREADME.txt
[Email protected] jdk1.8.0_131]#

Create an environment variable file: (For ease of maintenance, create an app's environment variable file below)

[Email protected] jdk1.8.0_131]# vim/etc/profile.d/java-jdk.sh
[email protected] jdk1.8.0_131]# cat!$
cat/etc/profile.d/java-jdk.sh
Export java_home=/data/jdk/jdk1.8.0_131
Export path= $JAVA _home/bin: $PATH
Export classpath=.: $JAVA _home/lib/dt.jar: $JAVA _home/lib/tools.jar

After the deposit exits, use the source to take effect:

[Email protected] jdk1.8.0_131]# source!$
source/etc/profile.d/java-jdk.sh

To test the Java environment:

[Email protected] jdk1.8.0_131]# java-version
Java Version "1.8.0_131"
Java (TM) SE Runtime Environment (build 1.8.0_131-B11)
Java HotSpot (TM) 64-bit Server VM (build 25.131-b11, Mixed mode)
[Email protected] jdk1.8.0_131]#

Second, configure Maven

[Email protected] maven]# pwd
/data/maven
[[email protected] maven]# ls
Apache-maven-3.5.0-bin.tar.gz

Extract:

[Email protected] maven]# tar zxvf apache-maven-3.5.0-bin.tar.gz ^c
[[email protected] maven]# ls
apache-maven-3.5.0 apache-maven-3.5.0-bin.tar.gz
[Email protected] maven]# CD apache-maven-3.5.0
[[email protected] apache-maven-3.5.0]# ls
Bin Boot conf lib LICENSE NOTICE README.txt

Configure and take effect environment variables:

[Email protected] apache-maven-3.5.0]# vim/etc/profile.d/maven.sh
[Email protected] apache-maven-3.5.0]# source!$
source/etc/profile.d/maven.sh
[Email protected] apache-maven-3.5.0]# cat/etc/profile.d/maven.sh
Export maven_home=/data/maven/apache-maven-3.5.0
Export path= $MAVEN _home/bin: $PATH
[Email protected] apache-maven-3.5.0]#

Test:

[Email protected] apache-maven-3.5.0]# mvn-v
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04t03:39:06+08:00)

[Email protected] apache-maven-3.5.0]#

Configuration is successful!

Third, install Jenkins:

[Email protected] ~]# Wget-o/etc/yum.repos.d/jenkins.repo Http://pkg.jenkins-ci.org/RedHat/jenkins.repo
[Email protected] ~]# rpm--import Http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key
[email protected] ~]# Yum Clean all
[[email protected] ~]# Yum Install Jenkins
[Email protected] ~]#

Configure Jenkins:
Modify the configuration file for Jenkins

[Email protected] ~]# Vim/etc/sysconfig/jenkins #默认端口是8080
* # Port Jenkins is listening on.
# Set To-1 to disable
55 #
jenkins_port= "8080"
57
# # Type:string
# # # Default: ""
# # Servicerestart:jenkins
61 #
# IP Address Jenkins listens on for HTTP requests.
All interfaces (0.0.0.0).
64 #
Jenkins_listen_address= ""
.

Modify the service script for Jenkins

[[email protected] ~]# vim/etc/init.d/jenkins 
.  
 64 # Search usable Java as/usr/bin/ Java might not-minimal version required by jenkins. 
 65 # See Http://www.nabble.com/guinea-pigs-wan Ted-----hudson-rpm-for-redhat-linux-td25673707.html 
 66 candidates= "

 74 " &NBSP
 75 for candidate in $candidates  ,
 76 do
 77  [-X $JENKINS _java_cmd "] && Amp Break
 78  jenkins_java_cmd= "$candidate"
.

Start the Jenkins service:
[[Email protected] ~]# Service Jenkins start
Starting Jenkins [OK]
[Email protected] ~]#

Visit the test for a moment:

Start interface Prompt password generation location:

[Email protected] ~]# Cat/var/lib/jenkins/secrets/initialadminpassword

Paste in the input box

Next, choose the recommended plug-in installation:

To start installing plugins:

After the installation is complete, you will be prompted to create the user:
