My Raspberry Pi 3b running Raspbian Stretch with desktop, Release 2017-09-07.

I want to install the "LAMP" on my Raspberry Pi.

I successfully install apache2 and PHP, and went on to install the mysql-server when the problem appeared.

I got this question for this days.

1. When I used the Official default sources

deb http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi and use sudo apt-get install mysql-serverto install mysql but the system was installed the "mariadb" as the result. And it don`t ask me the root password.

Then I reset the root password and go on install other software was succeed. But when I use the phpmyadmin or WordPress to control the mysql database. I can`t use the Root and password to login the phpmyadmin or WordPress.

2. When I use the Tsinghua University sources

deb http://mirrors.aliyun.com/raspbian/raspbian/ jessie main non-free contrib
deb-src http://mirrors.aliyun.com/raspbian/raspbian/ jessie main non-free contrib

and use sudo apt-get install mysql-server to install .The result was different.

The code is back.pi@raspberrypi:~ $ sudo apt-get install mysql-server

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 mysql-server : Depends: mysql-server-5.5 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Does anyone know how to solve this problem?

I had the same problem with not being asked to enter the root password during installation.

I found the answer here: Raspbian Stretch with MariaDB

Note that even though mysql -u root -p does not work, it works when you put a sudo in front: sudo mysql -u root -p. Do that, and then run the following:

sudo mysql -u root

[mysql] use mysql;
[mysql] update user set plugin='' where User='root';
[mysql] flush privileges;
[mysql] \q

Afterwards, connecting via just mysql -u root -p works fine.

I too have had issues with MySQL so many that I dont use it anymore on the Rpi. A drop in replacement is MariaDB, all your of scripts will work as it uses the same syntax. Also install PHPMyadmin

sudo apt-get install mariadb-server mariadb-client
  • This makes no difference. In fact, mysql-server and mariadb-server is actually the same. When you install mysql-server and then run mysql (client), you will see that you are actually logged on to mariadb anyway. – Mathias Conradt Oct 11 '17 at 19:56
