Looks like a real bug at least with el7 RPMs: [openxs@centos ~]$ rpm -qpl mysql-community-server-5.7.12-1.el7.x86_64.rpm | grep mysqld_multi warning: mysql-community-server-5.7.12-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY /usr/share/man/man1/mysqld_multi.1.gz [openxs@centos ~]$ The mysqld_multi file is NOT there :)

I would suggest additionaly adding mysqld_safe also on systemd servers. It is not included in the el7 server package, but it would be good with combination with mysqld_multi

Hi! Thanks for your report! There are several reasons mysqld_multi is removed from packages. It's a perl script and with rpmbuild automatic dep generator, server will get unwanted deps on perl packages. We also want to use native tools, that's why mysqld_safe is gone, We are using systemd as replacement. See: https://dev.mysql.com/doc/refman/5.7/en/server-management-using-systemd.html for help using MySQL under systemd. There are also less need for multi instance mysqld processes as lightweight containers makes it trivial to run several mysqld on the same hosts. For example MySQL in docker is available at: https://hub.docker.com/r/mysql/mysql-server/ Finally, systemd has native support for multi instances. We are looking at adding support for such services in future MySQL server releases.

Posted by developer: Noted in 5.7.13 changelog. On platforms for which systemd support is installed, systemd has the capability of managing multiple MySQL instances. For details, see http://dev.mysql.com/doc/refman/5.7/en/server-management-using-systemd.html. Consequently, mysqld_multi and mysqld_multi.server are not installed because they are unnecessary.
