MariaDB on ramfsUpdated at by ospi
MEMORY engine isn't sufficient for eg. functional testing, you can run mysql from ramfs pretty easily. After carefully tuning
innodb_* parameters and granting privileges to test users, create a "clean" copy of datadir.
# service mysql stop Shutting down MySQL.. [ OK ] # rsync -a /var/lib/mysql/* /var/lib/mysql_derp
Cleanup old datadir
/var/lib/mysql for some mounting action and add ramfs to
/etc/fstab, check uid+gid for mysql:mysql
none /var/lib/mysql ramfs defaults,gid=496,uid=497 0 0
Horrible hack to rsync the
/var/lib/mysql during service startup. Create
/etc/sysconfig/mysql (doesn't exist at least on my centos6.5 + mariadb10 installations:) containing following:
#!/bin/bash if [ "$mode" = "start" ] ; then rsync -a --delete /var/lib/mysql_derp/ /var/lib/mysql/ fi
When calling mysql init script
/etc/init.d/mysql it declares a nice variable
$mode and sources the file created above.
