I wanted to do some experimentation with Percona XtraDB Cluster (Galera) and I didn't want to use virtual machines. I'm already using MySQL Sandbox for many other projects so that's the natural choice. I've downloaded the tarball for Percona XtraDB Cluster 5.5.29 and I've extracted it to ~/opt/mysql/5.5.29-pxc. Then I've installed 3 nodes: make_sandbox 5.5.29-pxc -- --sandbox_port 4551 \ --sandbox_directory msb_5_5_29-pxc01  make_sandbox 5.5.29-pxc -- --sandbox_port 4552 \ --sandbox_directory msb_5_5_29-pxc02  make_sandbox 5.5.29-pxc -- --sandbox_port 4553 \ --sandbox_directory msb_5_5_29-pxc03  But when I try to start a node this error happens: 130327 14:21:03 [Note] WSREP: wsrep_load(): loading provider library '/home/dvee den/mysql/5.5.29-pxc/lib/libgalera_smm.so' 130327 14:21:03 [ERROR] WSREP: wsrep_load(): dlopen(): libssl.so.10: cannot open shared object file: No such file or directory 130327 14:21:03 [ERROR] WSREP: wsrep_load(/home/...

The last MySQL User Group NL meeting was last Friday. It's always nice to learn about MySQL and meet other MySQL users. There were two presentations: one about MySQL User Defined Functions (UDF's) and one about MySQL TCO. The slides are available from the meetup page . There are already a number of MySQL events announced for the next few months. I'll only list events in the Netherlands and Virtual events.
