Hi all, I'm load balancing 4 mysql databases using HAProxy. The setup seems to be working pretty well. Except I keep seeing these messages turning up in syslog: Mar 12 22:11:31 db1 kernel: [6058125.959624] type=1400 audit(1457820691.824:3029129): avc: denied { name_connect } for pid=801 comm="haproxy" dest=7778 scontext=system_u:system_r:haproxy_t:s0 tcontext=system_u:object_r:interwise_port_t:s0 tclass=tcp_socket It looks like SELinux is denying haproxy the ability to connect to the database. I haven't seen any real problems on the site that uses the database. But I was just wondering if this message looks familiar to anyone. Or if it looks like something I should try to correct. I tried grepping through audit.log for haproxy and piping it to audit2why, but I don't get any useful response back: [root at db1:~] #grep haproxy /var/log/audit/audit.log | audit2why -M haproxy Nothing to do I'm open to your thoughts and opinions! Thanks, Tim -- GPG me!! gpg --keyserver pool.sks-keyservers.net --recv-keys F186197B
