To Install Jenkins On Oracle Linux 8.8
Introduction:
A Jenkins plugin allows Continuous Integration to be performed using an open-source automation tool written in Java. Using Jenkins, you can continuously build and test your software projects, making it easier for developers to integrate changes and easier for users to obtain a fresh build.
Procedure
Step 1: First check the OS version by using the below command.
[root@linuxhelp ~]# cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="8.8"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="8.8"
PLATFORM_ID="platform:el8"
PRETTY_NAME="Oracle Linux Server 8.8"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:oracle:linux:8:8:server"
HOME_URL="https://linux.oracle.com/"
BUG_REPORT_URL="https://github.com/oracle/oracle-linux"
ORACLE_BUGZILLA_PRODUCT="Oracle Linux 8"
ORACLE_BUGZILLA_PRODUCT_VERSION=8.8
ORACLE_SUPPORT_PRODUCT="Oracle Linux"
ORACLE_SUPPORT_PRODUCT_VERSION=8.8
Step 2: Install java package by using the below command.
[root@linuxhelp ~]# yum install java-11-openjdk-devel -y
