When I install the MySQL it installs Maria's packages on the new Debian GNU/Linux 9 (stretch), any suggestions?
apt-get install mysql-server
回答1:
Debian Stretch (9.0) no longer includes MySQL . Some information on what's happening in the background when you try to install mysql-server is available here.
MariaDB is designed to be a fully compatible drop in replacement for MySQL but if you really want MySQL you should add the MySQL APT repository to your system as described here. After adding the repository do an apt update and then proceed to install the mysql-server package.
