[email protected] ~]# echo 192.168.43.27 jenkins.dockerhunt.com jenkins >> /etc/hosts
- Setting JAVA:
1: Download latest stable JDK and extract
[[email protected] ~]# tar -xvf jre-8u121-linux-x64.tar.gz

[[email protected] ~]# mkdir /usr/java
3: Move Java folder in to /usr/java
[[email protected] ~]# mv jre1.8.0_121 /usr/java/
4: Export Java home and bin like below,
[[email protected] ~]# export JAVA_HOME=/usr/java/jre1.8.0_121
[[email protected] ~]# export PATH=$PATH:$JAVA_HOME/bin/
5: Check Java version,
[[email protected] bin]# java -version
java version "1.8.0_121"

[[email protected] ~]# unzip apache-tomcat-7.0.76.zip
2: Create tomcat user and group
[[email protected] ~]# groupadd tomcat
[[email protected] ~]# sudo useradd -M -s /bin/nologin -g tomcat -d /opt/tomcat tomcat
3: Create tomcat home directory
[[email protected] ~]# mkdir /opt/tomcat
4: Move tomcat file into tomcat home
[[email protected] ~]# mv apache-tomcat-7.0.76/* /opt/tomcat/
5: Setup required file and directory permission on tomcat file
[[email protected] ~]# chgrp -R tomcat /opt/tomcat
[[email protected] ~]# chmod -R g+r /opt/tomcat/conf
[[email protected] ~]# chmod g+x /opt/tomcat/
[[email protected] ~]# chmod g+x /opt/tomcat/bin/*
[[email protected] ~]# chmod -R g+w /opt/tomcat/logs
[[email protected] ~]# chmod -R g+w /opt/tomcat/webapps/
[[email protected] ~]# chmod -R g+w /opt/tomcat/work/
[[email protected] ~]# chmod -R g+w /opt/tomcat/temp/
6: Create systemd service file for tomcat
vi /etc/systemd/system/tomcat.service
# Systemd unit file for tomcat
