Read: ''rsync' not found in PATH', issue with rsync

Hi dear experts,
I have installed latest PXC from repo on CentOS 7 as well as rsync. But when i started second node to connect to primary it gave an error, indicating that there is no rsync installed.

In fact rsync is installed as dependency package from Percona repo.

    Have you checked if any local machine firewall is blocking the access? Perhaps IPTables or even SELinux...

    Another check you can do is the --rsync-path

    After setting SElinux from enforcing to permissive secondary nodes started successfully.
    But rather than permanently disabling SElinux, i decided to activate policy for galera:
    yum install policycoreutils-python
    grep mysql /var/log/audit/audit.log | audit2allow -M galera
    semodule -i galera.pp
    
    setenforce 1

    Sounds good that it has worked...
