Hi. I enabled the SELinux in ENFORCING mode on my server of security reasons. Unfortunately when SELinux is ENFORCING its policy the MySQL replication is not working. Below is the output from 'dmesg'. Can please someone explain me simply how can I define a costum policy (add few rules to the existing one)? How to solve the below problem? Is there a simple document describing how can I create and configure a new role on an existing policy (I need persistent config - so after rebooting I would like my definitions are loaded automatically). << I already reat some docs about SELinux, however I didn't find a 'normal' doc for described tasks. # dmesg audit(1123620294.714:4): avc: denied { connect } for pid=2206 comm="mysqld" scontext=root:system_r:mysqld_t tcontext=root:system_r:mysqld_t tclass=tcp_socket audit(1123620294.714:5): avc: denied { name_connect } for pid=2206 comm="mysqld" dest=3306 scontext=root:system_r:mysqld_t tcontext=system_u:object_r:mysqld_port_t tclass=tcp_socket Thanks and best regards, Dezo
