First, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new.
apt-get update
Installing MySQL is as simple as running just one command:
apt-get install mysql-server php5-mysql
You may receive the following prompt or something similar:
After this operation, 98.2 MB of additional disk space will be used.
Do you want to continue? [Y/n]
Enter Y to continue.
Next you’ll be asked:
New password for the MySQL “root” user:
This is an administrative account in MySQL with elevated privileges; enter a strong password.
Then you’ll be asked to verify the root MySQL password:
Repeat password for the MySQL “root” user:
That’s it! Your basic MySQL installation is now complete!
Step 2: Configure and Secure MySQL for Use
Now we’ll instruct MySQL to create its database directory structure:
mysql_install_db
And now let’s secure MySQL by removing the test databases and anonymous user created by default:
mysql_secure_installation
You’ll be prompted to enter your current password. Enter the root MySQL password set during installation:
Enter current password for root (enter for none):
Then, assuming you set a strong root password, go ahead and enter n at the following prompt:
Change the root password? [Y/n] n
Remove anonymous users, Y:
Remove anonymous users? [Y/n] Y
Disallow root logins remotely, Y:
Disallow root login remotely? [Y/n] Y
Remove test database and access to it, Y:
Remove test database and access to it? [Y/n] Y
And reload privilege tables, Y:
Reload privilege tables now? [Y/n] Y
Step 3: Verify MySQL Installation
You can check the version of the MySQL installation with the following command:
mysql -V
Enter the MySQL command client:
mysql -p
You’ll be asked for the root password for the MySQL server, which was set earlier in this tutorial:
Enter password:
And then you should be greeted with the following:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 47
