Answer 1

Solved in CentOS 7 + MariaDB 10.2

I'm having same issue, and I would like to contribute with my answer. I've just installed in my 2 servers running CentOS 7 with MariaDB (10.2.14-MariaDB MariaDB Server) .

$ cat /etc/centos-release
CentOS Linux release 7.4.1708 (Core)

$ mysql
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is XXXX
Server version: 10.2.14-MariaDB MariaDB Server

I've installed MariaDB, this packages:

$ yum list installed | grep mariadb
MariaDB-client.x86_64                   10.3.13-1.el7.centos           @mariadb
MariaDB-common.x86_64                   10.3.13-1.el7.centos           @mariadb
MariaDB-compat.x86_64                   10.3.13-1.el7.centos           @mariadb
MariaDB-server.x86_64                   10.3.13-1.el7.centos           @mariadb
galera.x86_64                           25.3.25-1.rhel7.el7.centos     @mariadb

I found that the problem is that mysqlclient requires mysql-devel packages, which is different from mariadb-devel. Don't install mariadb-devel!

So, to install only mysql-devel, you need to:

1. Remove any MariaDB-devel

$ sudo yum erase MariaDB-devel.x86_64

2. Add MySQL repository in yum

1. Go to https://dev.mysql.com/downloads/repo/yum/ and select the RPM file for your CentOS (for me, I choose "Red Hat Enterprise Linux 7 / Oracle Linux 7 (Architecture Independent), RPM Package". Click "download".)
2. Download without registration, copy bottom link "No thanks, just start my download".
3. Go to your terminal and type:

$ wget link-to-rpm-you-choose

4. After download complete, type:

$ sudo rpm -Uvh your-rpm-downloaded

3. Now, install mysql-devel

1. Type (this is my version, watch yours):

$ sudo yum install mysql-community-devel.x86_64

4. Now, finally: mysqlclient

1. Type:

$  sudo pip install mysqlclient

You are using pip version 8.1.2, however version 19.0.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

And that's it! It worked like a charm and now I can use Python + Django + MariaDB/MySQL

Oh, and mysqlclient is the connector recommended by Django. See: https://docs.djangoproject.com/en/2.1/ref/databases/#mysql-db-api-drivers

Good luck and see ya! :-)
