LAMP environment installation within Ubuntu 14.04

This blog is to tell how to install LAMP environment within Ubuntu 14.04.

1. Install Mysql Server / Mysql Client.

　　1)Login your own server using any user you want.

　　2)Type in below command:

sudo apt -get install mysql-server mysql-client

　　3)During installation, will let you confirm the default password for mysql root user, will show like below screen shot.

　　　　Give them whatever it need, it's fine. Remeber your password, it's important!

　　　4) After some time waiting for it's own process, try login use the below command:

mysql -uroot -p

　　　Type in the password that you gave minutes ago and if it goes like this:

　　　　Congratulations! Your Mysql server is successfully installed!

　　　　Here I met a little problem, cannot connect mysql server use navicat. Fix like below, file location is /etc/mysql/my.cnf

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address　　　　　　　= 127.0.0.1
bind-address            = 0.0.0.0

2.Insatall PHP

　　1)Configure a PPA for co-installable PHP 5.6+7.0

　　　　Type in follow command:

sudo apt-get install -y language-pack-en-base
sudo LC_ALL=en_US.UTF-8 add-apt-repository ppa:ondrej/php

 sudo add-apt-repository ppa:ondrej/php

　　　　Form my own experience, I use the first way, and the sample output is like below:

　　2) Update the package index

　　　　To resynchronize the package index files from their sources, enter:

sudo apt-get update

　　　　Waiting until it's all done and type in below command for checking:

apt-cache search php7

　　3) Install PHP7

sudo apt-get install php7.0

　　4)Checking if php has mysql module

sudo cat /etc/php/7.0/mods-available/mysqlnd.ini

　　　　　This will give you results like below screenshot which means your extension is successfully installed:

　　　　　If not, type:

sudo apt-get install php7.0-mysql

　　　　　And then check.

3. Install Apache2

　　1) Install.

　　　　Update software source.

sudo apt-get update

　　　　Install Apache

apt-get install apache2

　　　　Check if Apache is successfully installed

apache2 -v

　　　　If it shows like below, then access your own server by typing your IP addressand if it is able to access, then it works！

　　2) Check the php extension.

　　　　Create a new info.php in the directory : /var/www/html

<?php
$link = mysqli_connect("127.0.0.1", "your_username", "your_password", "mysql");

if (!$link) {
    echo "Error: Unable to connect to MySQL." . PHP_EOL;
    echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
    echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
    exit;
}

echo "Success: A proper connection to MySQL was made! The my_db database is great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($link) . PHP_EOL;

mysqli_close($link);

phpinfo();
?>

　　　　And then access your IP/info.php using browser, If it shows like below, your installation is success!!

Some key points when set up the environment:

　　1) Make sure you have only one php version for apache, since if php7.0 and php5 are both in apache mods, it will conflict and unable to start apache.

　　2) Modify /etc/apache2/apache2.conf, Add one line under the #Global configuration, and then restart apache.

# Global configuration
#
ServerName 127.0.0.1
