In the previous entry we commented on how to have a portable MariaDB server, using the XAMPP tool, while in this entry, I propose that instead of MariaDB, let’s prepare a MySQL 8 as the server to work.
The first thing for having a MySQL portable version is that we can’t use the MySQL installer (in this blog I already told you how to install MySQL 5.6 with the installer). This time, we downloaded the zip version.
Once downloaded the file, unzip the file in the directory you like, and as a advice, avoid white space or wierd characters. In my case, I have it on f:mysql8
Before being able to start MySQL server, it is necessary to have a configuration file my.ini, a vital file for MySQL, and that we will have to create (or use one that we already have from another instance of MySQL).
A second very important aspect is that the directory data is not included, which is where the databases are normally located, so it will be necessary to carry out some intermediate steps.
But first, let’s create a configuration’s file (in this link, you have what I use when working with MySQL 5.6):
The my.inifiel is the configuration file for MySQL, but if you look in the /bin, you won’t find anyone. You need to create on. Here I have one for you with the basic parameters, based on the directories I have used:
# my.ini para MySQL 8.0.x de @manejandodatos . http://manejandodatos.es
Here, you can see the config file:
Creating a _start.bat file for starting MySQL
The easiest way to start a MySQL server is by creating a _start.bat file that avoid us to repeat the instruction every time you want to start the server, and it is very simple:
I also have include th efile under the mysql8 directory.
Now, open a console, and execute the _start.bat file and …
… I have a “nice” error, because the server is still not ready: the configuration of the server is not finished.
To avoid this error, you only need to modify the first initialization of the server including –initialize option (in MariaDB, this option is worthless)
mysqld --initialize --console
Of course, you can read in the documentación about this initial step adn all you need to know..
WARNING!This process of starting the data directory has a different approach on MariaDB, where there is no –initialize option.
Inicializaation of the data directory
To do that, let’s execute the next command:
binmysqld.exe –initialize –console
And in a few seconds, the initialize process is executed, accesing the my.ini config file.
As you can read in the last line of the report, the initializing process has created the data dir, but also, it has created a temporary password for the root user. And,do not forget the password!!!
Nowm you can start the server using the _start.bat file, and as you can check, it is up and running:
Let’s try accesing the MySQL server by using the temporary password. To do that, let’s open a new console, go to your path (in my case f:mysql8bin), and write this command:
mysql -u root -p
and you are asked for the temporary password:
But, with the temporary password, MySQL doesn’t allow us to use the server. You need to change it:
So, following the instructions in the documentation, the way to change the user’s password from root to root-password (here you write yours !) is with the command:
ALTER USER 'root'@'localhost' IDENTIFIED BY 'root-password';
Now, you can execute the query to check what version of the server we are using:
Of course, if you need your server in a different unit, you just need to modify the my.ini file to the right path and also modify _start.bat.
Let’s use HeidiSQL now to verify that everything is ready to work:
And that’s all for this entrance. I hope this content will be useful for you and …
