#42977 [NEW]: localhost setting goes to socket instead of 127.0.0.1

From: marc at perkel dot com Operating system: linux PHP version: 5.2.4 PHP Bug Type: MySQL related Bug description: localhost setting goes to socket instead of 127.0.0.1 Description: ------------ When a PHP application tries to call MySQL and it is set to talk to localhost it talks only to the socket and not to TCP 127.0.0.1. In my.cnt I set the client as follows: [client] protocol=TCP However that is ignored. I'm running a web server hosting some 100 applications installed by many different people. So changing all the localhost setting to 127.0.0.1 isn't practical. What I want to do is not use the socket at /var/lib/mysql/mysql.sock at all. The reason is that I'm trying to mugrate all mysql to a dedicated mysql server and having the web server talk to 127.0.0.1 and link them with an SSH tunnel. In this setup there will be no socket. I left a bug report at mysql.com and they blame the problem on PHP so i'm now here to let you know about it. Reproduce code: --------------- Set configuration to localhost and disable socket and PHP can't talk to TCP 127.0.0.1 Expected result: ---------------- I expect PHP to ignore the unix socket and talk to TCP 127.0.0.1 Actual result: -------------- No access -- Edit bug report at http://bugs.php.net/?id=42977&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42977&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42977&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42977&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42977&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42977&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42977&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42977&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42977&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42977&r=support Expected behavior: http://bugs.php.net/fix.php?id=42977&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42977&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42977&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42977&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42977&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42977&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42977&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42977&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42977&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42977&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42977&r=mysqlcfg
