# echo "Install httpd (apache server) if needed ..."
# yum install httpd
# service httpd restart
# chkconfig httpd on


2.2. Setup Yum Repository for SVN Subversion

# vim /etc/yum.repos.d/wandisco-svn.repo

Now you must have faith. You will remove all your local files and check project out from repository in your SVN local copy

# echo "Go to working directory"
Go to working directory
# cd ~/my-svn-working-copy
# ls
drwxr-xr-x 5 root root 4096 Sep 12 15:13 _templateSvnProject
# rm -rf ./_templateSvnProject

Installing Jenkins - CentOs 6.5

Installing Jenkins for CentOS 6.5


1. Introduction


This post shows how to install Jenkins for CentOS 6.5


2. Step by Step


2.1. Check/Install JDK or JRE

Check if JDK 1.6 or greather is available on machine. Depending on the purpouse of your Jenkins instalation, you will need to instal JDK (I strongly recommend). If you just want to take a look in Jenkins, so you can install JRE.

# java -version
java version "1.7.0_65"
OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)
OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)         
                                                                # echo "Execute following command if JRE is not installed ..." 
# yum install java
        :
        :
#
# echo "I decided to install more than a simple JRE because I will compile code"
I decided to install more than a simple JRE because I will compile code
# yum install java-1.7.0-openjdk-devel
        :
        :

2.2. Add Jenkins repository to machine

# 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


2.3. Install Jenkins

# yum install jenkins

2.6. Check Jenkins services

a. Checking Port Service

# echo "Jenkins default port is 8080. Check port listening ..."
# netstat -tnlp | grep 8080


b. Checking firewall rules

# echo "Check if port 8080 is listening ..."
# service iptables status
