Install MySQL 5.7 on Ubuntu 18.04

This article is compiled with reference to the MySQL official website, and some problems encountered are recorded by the way.

① Add the MySQL APT repository to your system’s software repository list

----> Download APT repository (download link)

---->Install the APT repository (pay attention to the correct path)

(1)

sudo dpkg -i mysql-apt-config_0.8.10-1_all.deb

Here is a tutorial written under Ubuntu on Tencent Cloud. After I executed the above command in Tencent Cloud, the MySQL installation interface popped up directly.

When I installed it on my computer, after installing the APT repository, I executed the following command

(2)

sudo apt-get update

Then install MySQL

(3)

sudo apt-get install mysql-server

If you execute code (1), the following interface will pop up.

You can continue to operate directly. If the screen does not pop up, just execute (2) (3) commands normally, and the above screen will pop up. There's no big problem here.

But I don’t know why the installation screen pops up directly when I execute command (1) in Tencent Cloud. I have just started learning Linux. Or if anyone knows, please leave a message to discuss.

②Install MySQL

As shown in the picture above, I choose not to install version 8.0 because it does not match my computer development environment. Of course, you can install 8.0, it depends on your personal preference.

Press Enter to select the first one and enter the following screen

I chose version 5.7. continue.

Keep the rest as default or change them if necessary.

Hey! There is a problem. I selected ok and it was done.

Then let me continue to enter commands. Well, we'll adapt to the situation, so let's try (2) command

sudo apt-get update 

Then after the update, we continue with (3) command

sudo apt-get install mysql-server

Well, it's installed normally.

Then you will be asked to enter the password for the database root account. I remember that the password must contain uppercase and lowercase letters, special symbols and must be no less than 8 characters.

Then enter it again to confirm.

This completes the installation.

We enter the command to log in to mysql to see if the installation is successful.

mysql -u root -p

Then enter the password. If the following mysql> appears, it is successful.

There is also the complete removal of MySQL and the visualization tool workbench, but I won’t put them here. If you need them later, please contact me and I will add them.

The above is the full content of this article. I hope it will be helpful for everyone’s study. I also hope that everyone will support 123WORDPRESS.COM.
