I assume that you have a Centos installation.

Installation

You can copy/paste this script and use it to configure automatically your server.

#!/bin/bash
 
echo "import repository jenkins"
sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import http://pkg.jenkins-ci.org/redhat/jenkins-ci.org.key
 
echo "install java and jenkins"
dnf -y install java-1.8.0-openjdk jenkins
 
 
echo "configure httpd (create /etc/httpd/conf.d/jenkins.conf)"
cat > /etc/httpd/conf.d/jenkins.conf << "EOF"
ProxyPreserveHost On
Proxypass /jenkins http://localhost:8080/jenkins
Proxypassreverse /jenkins http://localhost:8080/jenkins
ProxyRequests     Off
EOF
 
 
echo "configure jenkins"
 
#change home directory
mkdir -p /opt/jenkins_home
chown jenkins:jenkins /opt/jenkins_home -R
sed -i "s/^\(JENKINS_HOME=\).*/\1\"\/opt\/jenkins_home\"/" /etc/sysconfig/jenkins
 
#configure jenkins prefix tu run begin apache:
sed -i "s/^\(JENKINS_ARGS=\).*/\1\"--prefix=\/jenkins\"/" /etc/sysconfig/jenkins
 
#Security-Enhanced Linux (SE-Linux)
setsebool -P httpd_can_network_connect true
 
echo "start jenkins"
systemctl restart httpd.service
systemctl start jenkins.service
 
 
myip=`hostname -I`
echo "Now meet you here: http://$myip/jenkins"
 
 

That’s all 🙂
