Re: [lxc-users] The dark side of LXC
Did you mean 10.0.12? 10.0.1 is an alpha release https://mariadb.com/kb/en/mariadb/development/release-notes/release-notes-mariadb-100-series/mariadb-1001-release-notes/ Also, as a side note, if you have another program which uses libmysqlclient18 AND does version checking (e.g. php-5.3) AND using mariadb 10 to replace the distro's bundled mysql server, you might see sudden flood of warning messages (e.g. on php's error log) saying mismatch version between headers and client library version. There are ways to workaround this issue though, one of them is to NOT replace the distro's version of mysql client, and install mariadb separately from generic binary tarball. The other method is have the server and client on separate containers/servers. Just a heads-up in case anyone stumbles on this problem. -- Fajar On Mon, Jul 14, 2014 at 11:03 AM, CDR vene...@gmail.com wrote: I switched to MariaDB 10.0.1. It works fine.
