laravel and vuejs installation in aws from scratch

services

compute

ec2

volumes

create a volume

give the examle gb 100

create volume

come down

create voluem

after created volume

its redirect to voulme list page

u can click on created volme

u can see total volume details

then go to instances

left side bar

click on launch instance at instanc page

after its redirect to instance page

give the name

select os ( i selected ubuntu)

slect the machine image

architechture (default selected(

select the key or create new key pair

pem is for ssh

ppk is for putty

aftrer click on create key pair

it wil download to your local

remember the location where it is stored

after thet click on instances in side bar

then click on required instance row clock

click on connect

it wirll redirect to instance page

you have pem file

go to where downloaded

and then enter

chmod 400 "pem file name"

then

ssh -i "pem file" ubuntu@ipaddressor domain name

given in above image

whjenver u enter that in terminal it shows connected succesfully then

it will show specs

go back to list on instances page at aws

click on required isntances

it show the details in below window

click on security tab

click on that blue link security groups under

click on edit inbound rules

then

edit inbound rules

in terminal

sudo password root

change password

new password

retype

then chang e

sudo nano /etc/ssh/sshd_config

sudo service sshd reload

then

sudo apt update

sudo apt upgrade

sudo apt install zip unzip

sudo apt install apache2

sudo service apache2 restart

it have to show like this default page when u visit browser ( when u copy the public ipv4dns)

then start to install laravel application using docker

clone the git repository this

git clone https://gitlab.com/vamsigdv/docker-laravel.git

it is a public repository

then there is no need of user name and apassword

then

then move to docker-laravel

git checkout laravel

swithc to laravel branch

git pull orgin laravel

docker-compose u p -d

not installaed docker

so install docker step by step

sudo apt update

sudo apt install apt-transport-https ca-certificates curl software-properties-common

Next, install a few prerequisite packages which let apt use packages over HTTPS:

sudo apt install apt-transport-https ca-certificates curl software-properties-common

Then add the GPG key for the official Docker repository to your system:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Add the Docker repository to APT sources:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

Finally, install Docker:

sudo apt install docker-ce

Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it’s running:

sudo systemctl status docker

if u know the terminal password

sudo usermod -aG docker ${USER}

su - ${USER}

docker -v

docker-compose -v

sudo apt install docker-compose

to know the password

cat /etc/password

if sudo is must

sudo -i

sudo docker-compose up -d

docker ps -a

to knwo the containers status

docker images -a

to know the images status

url:8000

in docker file u can see the

docker-compose.yml in

phpmyadmin_testing:
    container_name: phpmyadmin_testing
    image: phpmyadmin/phpmyadmin
    restart: always
    environment:
        - PMA_HOST=mysql_testing
        - PMA_PORT=3306
    ports:
        - 8000:80

this is the database name and passwor d

 "MYSQL_USER=testing"

        - "MYSQL_PASSWORD=ueDMcQVb8JVCyjws"

check nginx server

 nginx:
    container_name: nginx
    image: nginx:1.17
    restart: always
    ports:

        - "9999:9999"

url:9999

check the databse connecting to root password

sudo docekr exec -it mysql_testing mysql -uroot -pueDMcQVb8JVCyjw

 docker exec -it mysql_testing mysql -uroot -pueDMcQVb8JVCyjw

  - "MYSQL_ROOT_PASSWORD=ueDMcQVb8JVCyjw"

        - "MYSQL_DATABASE=testing"

its logined to database from terminal

show databases;

exit

./dock php php artisan migrate

if it is migratee it is ok

otherwise

error



change the folder name to

oocker-laravel

nginx/default.conf folder

i given my-laravel-app

so change the folder name to docker-laravel

folder nam e

is

www/ in this location all fodlers is to be

move this folder

mv docker-laravel www

docker-laravel move to www

then connect docker to mynetwork

docker network create --driver bridge mynetwork

docker network inspect mynetwork

docker network connect mynetwork php
docker network connect mynetwork mysql_testing
docker network inspect mynetwork

ls dockerFIle

nano DockerFile

if u got any eror while crfeating containers or iamges

just remove contaienrs and images , then re build

docker kill $(docker ps -q)
docker rm $(docker ps -a -q)

docker rmi -f $(docker images -q)

remove the container

sudo docker rm  composer php phpmyadmin

stop the contaienrs and then remove the containers
