Environment Preparation

This guide covers deploying a complete service stack on CentOS 7. The /data/ directory serves as the mounted storage location, with installation packages stored in /data/install-page.

1. Setting Up Local YUM Repository

Creating Mount Point

mkdir -p /mnt/centos

Mounting ISO Image

Upload the CentOS 7 ISO file to /data/install-page, then mount it:

mount -o loop /data/install-page/CentOS-7-x86_64-DVD-2009.iso /mnt/centos

Backing Up Existing YUM Configurasion

cd /etc/yum.repos.d/
mkdir backup
mv *.repo backup/

Creating Local Repository Configuration

vi /etc/yum.repos.d/local.repo

[centos-local]
name=CentOS-7 - Local
baseurl=file:///mnt/centos
gpgcheck=0
enabled=1

Rebuilding YUM Cache

yum clean all
yum makecache

Configuring HTTP Access to YUM Repository

vi /data/nginx/conf.d/yumserver.conf

location /centos {
    alias /mnt/centos/;
    index index.html;
    autoindex on;
}

2. Installing JDK

Creating Installation Directory

mkdir -p /data/install-page
cd /data/install-page

Downloading and Extracting JDK

wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.tar.gz
tar zxf jdk-17_linux-x64_bin.tar.gz -C /data/
mv /data/jdk-17.0.2 /data/jdk

Configuring Environment Variables

vi /etc/profile.d/jdk.sh

#!/bin/bash
export JAVA_HOME=/data/jdk
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

source /etc/profile
java -version
