Percona 5.7 and mysql-common

smaressmares EntrantInactive User Role Beginner
Is it safe to run percona-server-server-5.7 alongside mysql-common and libmysqlclient18 which are required by postfix-mysql and dovecot-mysql? Can the two communicate with the Percona server?

    There is no problem in the mix-and-match different packages, as long it is the same major version (5.7)

    OK, since you mentioned it has to be the same major version, I went ahead and wanted to install mysql-common 5.7 using the MySQL apt repo, but that won't work.

    It does work though if I use the MySQL version provided by Debian directly which is a 5.5.

    I think it's related to libmysqlclient18. With the MySQL apt repository and set to MySQL 5.7, libmysqlclient18 would provide 5.7.5-m15-2debian8. Without the MySQL repository relying on Debian's packages, it would provide 5.5.
    Percona has different libperconaserverclient per version, 18 for 5.5, 18.1 for 5.6 and 20 for 5.7. Since postfix-mysql requires libmysqlclient18, I can either go with libmysqlclient18 from Debian giving me 5.5 or libperconaserverclient18 giving me also 5.5. Would that connect to a 5.7 server at all?

    Since I cannot edit my previous post (or don't see how), just wanted to drop a short update that libperconaserverclient18 does NOT provide libmysqlclient18 so my only option is to use the libmysqlclient18 from the MySQL 5.5 Debian package.
