Amos, thanks for answering... So here is where i am. i configured my basic_db_auth and tested with /usr/lib64/squid/basic_db_auth --user root --password password --plaintext -- persist But my Centos does nothing, it stays blinking... so i need to crtl + c to stop.... I think something is blocking the connection with mysql, but i dont know what. Already disabled selinux. On cache.log it says 2015/08/18 21:16:22 kid1| helperOpenServers: Starting 0/5 'basic_db_auth' processes 2015/08/18 21:16:22 kid1| HTCP Disabled. Any idea if Centos 7 have anything that could block mysql connection ? or something like that ? It dont even show "wrong password" , just blinking... literally -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-Mysql-tp4672769p4672776.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
