Ubuntu 18.04 install MySQL Server

Ubuntu 18.04 install MySQL Server

Installation for MySQL is slightly different in 18.04 as compared to 16.04.

sudo apt update
sudo apt install mysql-server -y
sudo mysql -uroot

Now in MySQL console, type the following to check the users.

select user,host,plugin from mysql.user;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'NEWPASSWORD';
update mysql.user set host='%' where user='root';

Comment the line bind-address if you like to listen on all addresses.

sudo service mysql restart


Suppress Bash MySQL warning

Install Ubuntu MySQL client

I assume you already installed MySQL client in your Ubuntu 16.04. If you had not, then to install MySQL client in Ubuntu, type in the following commands. Having a MySQL client is useless if you do not have a MySQL server to query. To install MySQL server, you can refer to my Ubuntu install WordPress blog post.

sudo apt-get update
sudo apt-get install mysql-client -y

Execute MySQL statement in Bash

To execute a MySQL statement in Bash, simply type in the following. I assume your MySQL server is hosted locally using the user “root” and with the password “password”.

mysql --host=localhost --user=root --password=password --execute='select now()'

Alternatively, you can use the shorter version to execute the same statement with the syntax below.

mysql -hlocalhost -uroot -ppassword -e'select now()'

Suppress Bash MySQL warning

Executing your MySQL statement in Bash with your password revealed in plain text will cause a warning to appear each time you execute a statement. It is quite annoying if you are running a loop executing MySQL statements with its output in stdout.

To suppress the warning, type the following commands. Key in your password when it prompts you for the password.

mysql_config_editor set --login-path=localhost --host=localhost --user=root --password

After that execute your MySQL statements using the syntax below. Both statements are the same, one long and one short depending on your preference. By executing it this way, MySQL warning is no longer there.

mysql --login-path=localhost --execute='select now()'
mysql --login-path=localhost -e'select now()'
suppress mysql warning

Install Apache

I assume you had already installed Apache into your Ubuntu elastic compute cloud ( EC2 ) instance. If you had not, then read my test Cloudflare DNS blog post, I had written about installing Apache. The entire guide below is using Ubuntu 16.04.

Configure Rewrite Module

This step is optional if you do not mind seeing “index.php” with query strings suffix after it. To remove it, you’ll need to configure the rewrite module in Apache. Go to /etc/apache2/sites-available/ and edit the file 000-default.conf and add the following codes in between the “VirtualHost” tag. After that type in the following commands to enable rewrite module.

<Directory /var/www/html>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Require all granted
sudo a2enmod rewrite
sudo service apache2 restart
ubuntu install wordpress

Install MySQL server

To install MySQL server, type in the following commands in your Ubuntu terminal. During installation, it will prompt you for the root password. Type in your desired root password and repeat the same password in the next screen.

Next type in mysql_secure_installation. You will be prompted with a series of questions, you can answer accordingly as per my example. Create a database for WordPress use with the commands below. In my example, my database root user password is “password”. Replace the password with the password you entered earlier when you install MySQL server.

sudo apt-get update
sudo apt-get install mysql-server -y
ubuntu install wordpress

mysql -uroot -ppassword -e 'create database wordpress'

Creating a database for WordPress by executing the MySQL statement with your password reveal in plain text will cause a warning. To suppress Bash MySQL warning you will need to store the password in the encrypted “.mylogin.cnf” file.
