Comment on Create a Master Master MySQL replication – Ubuntu Server 10.04 x64 by hatem

Actually I used this to migrate a system from a single node to a dual-node cluster, MySQL default packages was quite stable and enough for me. Notice that I used the mysql-server mysql-client packages only, not the cluster one.

Nice post, thanks. Have you tried setting up a cluster with myslq cluster 7.1 on Ubuntu Lucid? Would be nice with a post on that, I couldn’t find any info at all on this on the web… other than people having trouble installing mysql cluster on Lucid 10.04.

Best

The main cause is the language of the printer itself, PCL printers such as HP, PostScript such as Epson, Interpress such as Xerox and finally the latest PDL which is the most latest and including most of the former mentioned languages, simply talk, you have to include a format for each printer in your application. I didn’t mention the Barcode printers because a little bit different on how it is receiving data and also printing languages.
