I have a three node cluster already setup with percona xtradb cluster 5.7 which works fine, however, I would like like to create the 4th server and then setup master-slave replication with the third node as the master and 4th the slave. and would i require SSL certs?
while following this How to setup a slave for replication in 6 simple steps with Percona XtraBackup as a guide, i run into issues trying to configure the master when i run the command in step one in the documentation which gives me the error highlighted in yellow in the image below.
First off, innobackupex is dead software. You should be using xtrabackup instead. Next, you’re reading a very out dated (EOL). You need to be reading the Xtrabackup 2.4 documentation. Lastly, innobackup/xtrabackup are physical backup tools, which means they must be ran on a machine with mysql data already running to create the backup. You do not run this tool on the new replica. Look for the xtrabackup documentation on “streaming backup”
