How to install LAMP with Amazon EC2 CentOS 7

Introduction

Following tutorial help you install Apache, Maria-db, PHP and phpMyAdmin

Prerequisite

Launch Ec2 Instance of Amazon Linux
Allow Following PORT

80 - http
22 - SSH
443 - https

If port are not allowed follow instruction else ignore it.

Add a security rule to allow inbound HTTP (port 80) connections to your instance if you have not already done so. By default, a launch-wizard-N security group was set up for your instance during initialization. This group contains a single rule to allow SSH connections.

Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
Choose Instances and select your instance.
Under Security groups, choose view inbound rules.
You should see the following list of rules in your default security group:

Security Groups associated with i-1234567890abcdef0
Ports Protocol Source launch-wizard-N
22 tcp 0.0.0.0/0 ✔
Using the procedures in Adding Rules to a Security Group, add a new inbound security rule with the following values:
Type: HTTP
Protocol: TCP
Port Range: 80
Source: Custom

Install LAMP

Update Your System

Connect Your instance

$ ssh -i "path/to/your/private/pemfile.pem" ec2-user<publicdns or IP>

2. Insure that, all packages are upto date.

[ec2-user ~]$ sudo yum update -y

Install Apache, PHP and MySQL using YUM command

1. First install mariadb and Amazon Linux repository for latest package of PHP, and mysql.

[ec2-user ~]$ sudo amazon-linux-extras install lamp-mariadb10.2-php7.2

2. Now install Apache Web Server , PHP and MySQL Server at this instance.

[ec2-user ~]$ sudo yum install -y httpd php mariadb-server php-mysqlnd

`Configure APACHE Web Server`

1. Start Web Server

[ec2-user ~]$ sudo systemctl start httpd

2. Allow Apache Web Server start at boot time automatically.

[ec2-user ~]$ sudo systemctl enable httpd

3. Verify httpd, running at boot or not use the following command
[ec2-user ~]$ sudo systemctl is-enable httpd

4. Test your web server. In a web browser, type the public DNS address (or the public IP address) of your instance.

If you are unable to see the Apache test page, check that the security group you are using contains a rule to allow HTTP (port 80) traffic.

Modify Permission of /var/www/html folder of Web Server

Apache Server file which kept in /var/www/html folder this is called root folder and this is owned by root user. Allow the ec2-user account to manipulate files in this directory, you must modify the ownership and permissions of the directory.

[ec2-user ~]$ ls -l /var/www


total 16
drwxr-xr-x 2 root root 4096 Jul 12 01:00 cgi-bin
drwxr-xr-x 3 root root 4096 Aug  7 00:02 error
drwxr-xr-x 2 root root 4096 Jan  6  2012 html
drwxr-xr-x 3 root root 4096 Aug  7 00:02 icons
drwxr-xr-x 2 root root 4096 Aug  7 21:17 noindex

Add the ec2-user user to the apache group, to give the apache group ownership of the /var/www directory and assign write permissions to the group.

To set file permissions

Add your user (in this case, ec2-user) to the apache group.
```
[ec2-user ~]$ sudo usermod -a -G apache ec2-user
```
Log out and then log back in again to pick up the new group, and then verify your membership.
1. Log out (use the exit command or close the terminal window):
```
[ec2-user ~]$ exit
```
2. To verify your membership in the apache group, reconnect to your instance, and then run the following command:
```
[ec2-user ~]$ groups
ec2-user wheel apache
```
Change the group ownership of /var/www and its contents to he apache group.
```
[ec2-user ~]$ sudo chown -R ec2-user:apache /var/www
```
To add group write permissions and to set the group ID on future subdirectories, change the directory permissions of /var/www and its subdirectories.
```
[ec2-user ~]$ sudo chmod 2775 /var/www
[ec2-user ~]$ find /var/www -type d -exec sudo chmod 2775 {} \;
```
To add group write permissions, recursively change the file permissions of /var/wwwand its subdirectories:
```
[ec2-user ~]$ find /var/www -type f -exec sudo chmod 0664 {} \;
```

To test your LAMP web server

If your server is installed and running, and your file permissions are set correctly, your ec2-user account should be able to create a PHP file in the /var/www/html directory that is available from the internet.

Create a PHP file in the Apache document root.

[ec2-user ~]$ echo "<?php phpinfo(); ?>" > /var/www/html/phpinfo.php

In a web browser, type the URL of the file that you just created. This URL is the public DNS address of your instance followed by a forward slash and the file name. For example:
```
http://my.public.dns.amazonaws.com/phpinfo.php
```
You should see the PHP information page:

To secure the database server

Start the MariaDB server.

[ec2-user ~]$ sudo systemctl start mariadb

1. When prompted, type a password for the root account.
  1. Type the current root password. By default, the root account does not have a password set. Press Enter.
  2. Type Y to set a password, and type a secure password twice. For more information about creating a secure password, Type Y to remove the anonymous user accounts.
2. Type Y to disable the remote root login.
3. Type Y to remove the test database.
4. Type Y to reload the privilege tables and save your changes.
Use chkconfig command to on MySQL server to start at every boot.
```
[ec2-user ~]$ sudo systemctl enable mariadb
```

Install phpMyAdmin

phpMyAdmin without SLS/TLS in Apache is not recommended, it is very insecure.

Install the required dependencies.

[ec2-user ~]$ sudo yum install php-mbstring -y

Restart Apache.

[ec2-user ~]$ sudo systemctl restart httpd

Navigate to the Apache document root at /var/www/html.
```
[ec2-user ~]$ cd /var/www/html
[ec2-user html]$ 
```
Select a source package for the latest phpMyAdmin https://www.phpmyadmin.net/downloads. and installed it.
```
[ec2-user html]$ wget https://www.phpmyadmin.net/downloads/phpMyAdmin-latest-all-languages.tar.gz
```

Extract the package and change the name of the resulting directory to something more manageable.

[ec2-user html]$ tar -xvzf phpMyAdmin-latest-all-languages.tar.gz
[ec2-user html]$ mv phpMyAdmin-4.7.5-all-languages phpMyAdmin

In a web browser, type the URL of your phpMyAdmin installation.

http://my.public.dns.amazonaws.com/phpMyAdmin

You should see the phpMyAdmin login page:
