How to restore our internal server from aws (s3bucket)?

Prerequisites

Before starting, ensure you have:

  1. Server root login credentials.

Step 1:

Log into server

ssh username@ip

Step 2:

Install AWS CLI and configure

apt-get update
apt-get install awscli
aws configure

Note: Provide access & secret key while configuring

Step 3:

Copy the backup files from S3 to server

 aws s3 cp s3://cablemanagement-63141233102/apachebackup_1701220000.tar .
 aws s3 cp s3://cablemanagement-63141233102/sitebackup_1701220000.tar .
 aws s3 cp s3://cablemanagement-63141233102/sitebackup1_1701220000.tar .
 aws s3 cp s3://cablemanagement-63141233102/db_backups/db_backups-2022-01-17-0000.tar.gz .

Step 4:

Install apache2 and MySQL

 apt-get update
 apt-get install apache2
 apt update
 apt install mysql-server

Note: If this restoration is done on a new server we need to install apache2, mysql, mongodb. It's based on the developer requirement.If it is old server we need to check whether we have or not

Step 5:

Untar the backup file and copy the home directory

tar -xvf sitebackup_1701220000.tar
cp -pr home /

Step 6:

First we will set up the backend code. Go into the fitness_be and create a .env file. Include the db credentials like below

 cd taxary
 vi .env

Copy and paste the below.

 PORT = 4006

 OTP_KEY = 5dd572c3-87c0-11ea-9fa5-0200cd936042

 DBLINK = mongodb://127.0.0.1:27017/fitness_be

 JWT_SECRET=abcfghistuvwxyz123456789

 JWT_TIMEOUT_DURATION="2d"

 AUTHSOURCE = admin

 USER = admin

 PASS = ******

 

Note:- Modify the username and password as per your wish. |}

Step 7:-

First we have to add curl to the system

apt-get install curl
curl -fsSL https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

Step 8:

Install mongodb

apt update
apt install mongodb-org
sudo systemctl start mongod.service
sudo systemctl status mongod
sudo systemctl enable mongod

Step 9:

After installing mongodb. Follow the below commands.

 mongo( you will be entering in to mongo)

 use admin;

 Remember, If you don't use the admin database the below creation wont work. You will end up with errors.

 db.createUser( {user: “admin",pwd: “password",roles: [ { role: "userAdminAnyDatabase", db:”admin" },{ role: "dbAdminAnyDatabase", db: 
 “admin" },{ role:"readWriteAnyDatabase", db: “admin" },{ role: 'root', db: 'admin' } ]})
 If you forget to give root access to the user, you can execute like belo

 use admin;

 db.grantRolesToUser('admin', [{ role: 'root', db: 'admin' }]) 

 To check the privileges of the user

 db.getUser("admin")  

 To delete or drop the user  

 db.dropUser("admin", {w: "majority", wtimeout: 5000})

Step 10:

Install node js (required node version) and pm2. You can ask the developer for the version.

Example:-

https://computingforgeeks.com/how-to-install-nodejs-on-ubuntu-debian-linux-mint/

 npm install -g pm2
 sudo apt update
 sudo apt -y upgrade
 sudo apt update
 sudo apt -y install curl dirmngr apt-transport-https lsb-release ca-certificates
 curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
 sudo apt -y install nodejs
 sudo apt -y install gcc g++ make
 node --version
 npm --version
 mkdir ~/projects
 cd ~/projects
 vi hello-world.js
 node hello-world.js

Step 11:

Add user nagios and install daemon & nrpe (Nagios Remote Plugin Executor).

Note: These may vary according to the requirement of the developer

 sudo useradd nagios
 sudo apt update
 sudo apt install autoconf gcc libmcrypt-dev make libssl-dev wget dc build-essential gettext
 cd ~
 curl -L -O https://nagios-plugins.org/download/nagios-plugins-2.2.1.tar.gz
 tar -zxf nagios-plugins-2.2.1.tar.gz
 cd nagios-plugins-2.2.1
 ./configure
 make
 sudo make install
 cd ~
 curl -L -O https://github.com/NagiosEnterprises/nrpe/releases/download/nrpe-3.2.1/nrpe-3.2.1.tar.gz
 tar zxf nrpe-3.2.1.tar.gz
 cd nrpe-3.2.1
 ./configure
 make nrpe
 sudo make install-daemon
 sudo make install-config
 sudo make install-init
 df -h /
 vi /usr/local/nagios/etc/nrpe.cfg
 cd /home
 mv check_mem /usr/local/nagios/libexec
 systemctl restart nrpe
 vi /usr/local/nagios/etc/nrpe.cfg
 systemctl restart nrpe
 mv check_mem /usr/local/nagios/libexec
 cd /usr/local/nagios/libexec
 systemctl restart nrpe
 /usr/local/nagios/libexec/check_mem
 vi /usr/local/nagios/etc/nrpe.cfg
