Jenkins is a software that allows continuous integration. Jenkins will be installed on a server where the central build will take place.
System Requirements:
1. JDK
2. Tomcat
Java installation :
1. Download the latest JDK from Oracle's site
2. CentOS look for the package jdk-7u17-linux-x64.rpm (64-bit architecture) or jdk-7u17-linux-i586.rpm (32-bit architecture)
3. Once you download the installation package, use the command
4. Confirm you have the correct Java by running
Tomcat installation:
1. Download Apache Tomcat archive file from Apache Tomcat official download page. You can use below wget command to download it.
2. After competed download extract archive file in /tmp directory and move to proper location as per your need. We are placing this under /usr/local directory.
3. Tomcat by default start on port 8080, Make sure no other services are running on same port using ‘telnet localhost 8080'
4. Now access the tomcat home page at http://localhost:8080/
Increase the Tomcat Heap Memory:
1. Go to bin directory of tomcat server e.g. /usr/local/tomcat7/bin
2. Create or edit the setenv.sh file and add the following lines
3. After saving the file, restart the tomcat.
Create Tomcat credentials for Manager:
1. Go to conf directory of tomcat server e.g. /usr/local/tomcat7/conf
2. Edit the tomcat-users.xml file and add the following lines
4. After that save the file and restart the tomcat.
Setup Jenkins:
1. Download the latest Jenkins war file from it official site .
2. Copy the jenkins.war in tomcat webapps directory e.g. /usr/local/tomcat7/webapps and restart tomcat.
3. Now you can access the Jenkin application using the URL
http://localhost:8080/jenkins/

Tomcat installation:
1. Download Apache Tomcat archive file from Apache Tomcat official download page. You can use below wget command to download it.
cd /tmpwget http://www.us.apache.org/dist/tomcat/tomcat-7/v7.0.54/bin/apache-tomcat-7.0.54.tar.gz
2. After competed download extract archive file in /tmp directory and move to proper location as per your need. We are placing this under /usr/local directory.
tar xzf apache-tomcat-7.0.54.tar.gz
mv apache-tomcat-7.0.54 /usr/local/tomcat7
3. Tomcat by default start on port 8080, Make sure no other services are running on same port using ‘telnet localhost 8080'
cd /usr/local/tomcat7
./bin/startup.sh
4. Now access the tomcat home page at http://localhost:8080/
Increase the Tomcat Heap Memory:
1. Go to bin directory of tomcat server e.g. /usr/local/tomcat7/bin
2. Create or edit the setenv.sh file and add the following lines
export JAVA_OPTS="-Dfile.encoding=UTF-8 -Xms512m -Xmx1024m -XX:PermSize=64m -XX:MaxPermSize=256m"
3. After saving the file, restart the tomcat.
Create Tomcat credentials for Manager:
1. Go to conf directory of tomcat server e.g. /usr/local/tomcat7/conf
2. Edit the tomcat-users.xml file and add the following lines
<tomcat-users>
<role rolename="manager"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<user username="admin" password="admin" roles="manager,manager-gui,manager-script"/>
</tomcat-users>
4. After that save the file and restart the tomcat.
