This article shows you how to install the LAMP suite in Ubuntu. The content is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

1. Install the Apache Web server

First, update the Ubuntu server with the following command:

$sudo apt update$ sudo apt upgrade

Then, install the Apache Web server (command as follows):

$sudo apt install apache2

Check to see if the Apache Web server is running:

$sudo systemctl status apache2

The output looks something like this:

● apache2.service-The Apache HTTP Server Loaded: loaded (/ lib/systemd/system/apache2.service; enabled; vendor preset: en Drop-In: / lib/systemd/system/apache2.service.d └─ apache2-systemd.conf Active: active (running) since Tue 2019-02-05 10:48:03 UTC 1min 5s ago Main PID: 2025 (apache2) Tasks: 55 (limit: 2320) CGroup: / system.slice/apache2.service ├─ 2025 / usr/sbin/apache2-k start ├─ 2027 / usr/sbin/apache2-k start └─ 2028 / usr/sbin/apache2-k start Feb 05 10:48:02 ubuntuserver systemd [1]: Starting The Apache HTTP Server...Feb 05 10:48:03 ubuntuserver apachectl [2003]: AH00558: apache2: Could not reliablyFeb 05 10:48:03 ubuntuserver systemd [1]: Started The Apache HTTP Server.

Congratulations! The Apache service is up and running!

1.1 adjust the firewall to allow Apache Web servers

By default, if you have enabled UFW Firewall in Ubuntu, you cannot access the Apache Web server from a remote system. You must follow these steps to open the http and https ports.

First, list the application configuration files available on the Ubuntu system using the following command:

$sudo ufw app list

Output result:

Available applications:ApacheApache FullApache SecureOpenSSH

As you can see, Apache and OpenSSH applications have UFW configuration files installed. You can use the ufw app info "Profile Name" command to list information about each profile and the rules it contains.

Let's look at the "Apache Full" configuration file. To do this, run:

$sudo ufw app info "Apache Full"

Output result:

Profile: Apache FullTitle: Web Server (HTTP,HTTPS) Description: Apache v2 is the next generation of the omnipresent Apache webserver. Ports:80443/tcp

As you can see, the "Apache Full" configuration file contains transport rules that enable transport via ports 80 and 443:

Now, run the following command to configure to allow HTTP and HTTPS incoming traffic:

Sudo ufw allow in "Apache Full" Rules updatedRules updated (V6)

If you do not want to allow HTTP communication, but only allow HTTP (80) to communicate, run:

$sudo ufw app info "Apache" 1.2Test Apache Web server

Now, open a Web browser and navigate to http://localhost/ or http://IP-Address/ to access the Apache test page.

If you see a similar display above, it will be a success. The Apache server is working!

Mysql "class=" mume-header "> 2. Install MySQL

To install MySQL in Ubuntu, run:

$sudo apt install mysql-server

Verify that the MySQL service is running using the following command:

$sudo systemctl status mysql

Output result:

● mysql.service-MySQL Community ServerLoaded: loaded (/ lib/systemd/system/mysql.service; enabled; vendor preset: enabActive: active (running) since Tue 2019-02-05 11:07:50 UTC 17s agoMain PID: 3423 (mysqld) Tasks: 27 (limit: 2320) CGroup: / system.slice/mysql.service └─ 3423 / usr/sbin/mysqld-daemonize-pid-file=/run/mysqld/mysqld.pid Feb 05 11:07:49 ubuntuserver systemd [1]: Starting MySQL Community Server...Feb 05 11:07:50 ubuntuserver systemd [1]: Started MySQL Community Server.

MySQL is running!

2.1 configure Database Administrative user (root) password

By default, the MySQL root user password is empty. You need to secure your MySQL server by running the following script:

$sudo mysql_secure_installation

You will be asked if you want to install VALIDATE PASSWORD plugin (password Authentication plug-in). The plug-in allows users to configure strong password credentials for the database. If enabled, it automatically checks the strength of the password and forces the user to set a sufficiently secure password. It is safe to disable this plug-in. However, you must use unique strong password credentials for the database. If you do not want to enable this plug-in, just press any key to skip the password authentication section and continue with the remaining steps.

If the answer is y, you will be asked to select a password authentication level.

Securing the MySQL server deployment. Connecting to MySQL using a blank password. VALIDATE PASSWORD PLUGIN can be used to test passwordsand improve security. It checks the strength of passwordand allows the users to set only those passwords which aresecure enough. Would you like to setup VALIDATE PASSWORD plugin? Press y | Y for Yes, any other key for No y

The available password authentication is "low", "medium" and "strong". Simply enter the appropriate number (0 for low, 1 for medium, and 2 for strong password) and press enter.

There are three levels of password validation policy: LOW Length > = 8MEDIUM Length > = 8, numeric, mixed case, and special charactersSTRONG Length > = 8, numeric, mixed case, special characters and dictionary file Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG:

Now, enter the password of the MySQL root user. Note that the password must be used for the MySQL root user according to the password policy selected in the previous step. If you do not enable the plugin, you only need to use a unique password of any strength you choose.

Please set the password for root here. New password: Re-enter new password: Estimated strength of the password: 50Do you wish to continue with the password provided? (Press y | Y for Yes, any other key for No): y

After entering the password twice, you will see the password strength (50 in this example). If you are sure you can, please press y to continue to provide the password. If you are not satisfied with the password length, press any other key and set a strong password. My current password is OK, so I chose y.

For the rest of the questions, just type y and press enter. This removes anonymous users, disables root users from logging in remotely, and deletes the test (test) database.

Remove anonymous users? (Press y | Y for Yes, any other key for No): ySuccess. Normally, root should only be allowed to connect from'localhost'. This ensures that someone cannot guess atthe root password from the network. Disallow root login remotely? (Press y | Y for Yes, any other key for No): ySuccess. By default, MySQL comes with a database named 'test' thatanyone can access. This is also intended only for testing,and should be removed before moving into a productionenvironment. Remove test database and access to it? (Press y | Y for Yes, any other key for No): y-Dropping test database...Success. -Removing privileges on test database...Success. Reloading the privilege tables will ensure that all changesmade so far will take effect immediately. Reload privilege tables now? (Press y | Y for Yes, any other key for No): ySuccess. All done!

The above is to set the password for MySQL root users.

2.2 change the authentication method of the MySQL superuser

By default, MySQL root users of Ubuntu systems use the plug-in auth_socket to set authentication for MySQL version 5.7 and later. Although it enhances security, it becomes more difficult when you use any external program (such as phpMyAdmin) to access the database server. To solve this problem, you need to change the authentication method from auth_socket to mysql_native_password. To do this, log in to your MySQL prompt using the following command:

$sudo mysql

Run the following command at the MySQL prompt to find the authentication method for all MySQL current user accounts:

SELECT user,authentication_string,plugin,host FROM mysql.user

Output result:

+-|-+ | user | authentication_string | plugin | host | +- -|-|-+ | root | | auth_socket | localhost | | mysql.session | * THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost | | mysql.sys | * THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | Mysql_native_password | localhost | | debian-sys-maint | * F126737722832701DD3979741508F05FA71E5BA0 | mysql_native_password | localhost | +-|-|-- |- -+ 4 rows in set (0.00 sec)

As you can see, Mysql root users use the auth_socket plug-in for authentication.

To change this authentication to the mysql_native_password method, run the following command at the MySQL prompt. Don't forget to replace password with the powerful and unique password you choose. "if the VALIDATION plug-in is enabled, ensure that a strong password is used in accordance with the current policy requirements."

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY' password'

Update the database with the following command:

FLUSH PRIVILEGES

Use the command to check again that the authentication method has changed:

SELECT user,authentication_string,plugin,host FROM mysql.user

Output result:

good! MySQL root users can use a password for authentication to access the mysql shell.

Exit from the MySQL prompt:

Exit3. Install PHP

To install PHP, run:

$sudo apt install php libapache2-mod-php php-mysql

After installing PHP, create the info.php file in the root of the Apache document. Typically, in most Debian-based Linux distributions, the Apache document root is / var/www/html/ or / var/www/. Under Ubuntu 18.04 LTS system, the document root directory is / var/www/html/.

Create an info.php file in the Apache root directory:

$sudo vi / var/www/html/info.php

Edit the following in this file:

Then press the ESC key and type: wq to save and exit the file. Restart the Apache service for the changes to take effect.

$sudo systemctl restart apache23.1 Test PHP

Open a Web browser and navigate to the URL http://IP address / info.php.

You will see the PHP test page.

Typically, when a user makes a request to the Web server, Apache first looks for a file named index.html in the document root directory. If you want to change Apache to php files to provide services instead of other files, move the index.php in the dir.conf configuration file to the first location, as follows:

$sudo vi / etc/apache2/mods-enabled/dir.conf

The above configuration file (dir.conf) contains the following:

DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm # vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Move the index.php to the front. After the changes, the contents of the dir.conf file look like this.

DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm # vim: syntax=apache ts=4 sw=4 sts=4 sr noet

Then press the ESC key and type: wq to save and close the file. Restart the Apache service for the changes to take effect.

$sudo systemctl restart apache23.2 installs PHP module

To increase the functionality of PHP, you can install some other PHP modules.

To list the available PHP modules, run:

$sudo apt-cache search php- | less

Output result:

Use the arrow keys to browse the results. To exit, enter Q and press enter.

To find the details of any php module, such as php-gd, run:

$sudo apt-cache show php-gd

To install the PHP module, run:

$sudo apt install php-gd

To install all modules (although not necessary), run:

$sudo apt-get install php*

After installing any php modules, don't forget to restart the Apache service. To check if the module is loaded, open the info.php file in your browser and check for existence.
