I am using php-4.0.6 with MySQL-3.23.39 and there seems to be a problem with connecting to the database server. Problem that didn't happen with any previous version (even php-4.0.5 that i was using till today). phpinfo() shows a correct configuration and correct path to the socket, mysql server works correctly from console and i'm not using the bundled libraries (tried them also and it gave the same error). This was reproductible under OpenBSD-2.7-stable, OpenBSD-2.8, OpenBSD-2.8-stable, OpenBSD-2.9, OpenBSD-2.9-stable, Linux Debian (current), Linux RedHat 7.0, Linux Slackware 7.1 and probably others.


Configuration flags of PHP are:

--with-apache=/usr/local/apache --with-mysql=/usr/local/mysqlc --with-openssl=/usr/local/ssl --with-gd=/usr/local/gd --with-jpeg-dir=/usr/local --with-png-dir=/usr/local --with-zlib-dir=/usr/local --with-ttf=/usr/local --enable-apc --enable-calendar --enable-bcmath --enable-track-vars


MySQL related configuration directives in php.ini are:

mysql.allow_persistent = Off
mysql.max_persistent = 0
mysql.max_links = 1000
mysql.default_port = 3306
mysql.default_socket = /usr/local/mysqlc/var/mysql.sock
mysql.default_host = localhost


MySQL was compiled with the following flags:

--enable-static --localstatedir=/usr/local/mysqlc/var --with-libwrap=/usr --with-mysqld-user=mysqlc --with-unix-socket-path=/usr/local/mysqlc/var/mysql.sock --with-tcp-port=3306 --without-bench --without-mit-threads


Error returned:

Warning: Can't connect to local MySQL server through socket '/usr/local/mysqlc/var/mysql.sock' (13) in /home/www/k/kheos.net/test.php on line 3

Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/usr/local/mysqlc/var/mysql.sock' (13) in /home/www/k/kheos.net/test.php on line 3


Script that returned the error:

<? mysql_connect("localhost","joeuser","joepassword"); ?>


By the way, if someone would care to write a patch for:

I'd appreciate it cause i got poor C skills  ;p

It works fine here. Are you sure MySQl is actually running, and are the permissions on the socket correct?

Yeah, the server is actually running as i can connect to it from console. The socket is set srwxrwxrwx so it is also ok i presume.
The exact same configuration used to work with php-4.0.5 :/

Hello,

can you make a page with <?php phpinfo(); ?> available to us?

Derick
 [2001-07-04 15:41 UTC] veins at kheos dot net
of course  ;)

http://www.kheos.net/info.php

I'm making it right now so by the time you see this post it'll be available.

Best regards,
Veins

By the way, i've been testing a few things and php will connect to the database if i trick it into using tcp connection instead of socket connection and using LAN ip address instead of 'localhost' or loopback IP address.

Won't work:
<? mysql_connect("localhost:3306", "me","mypass"); ?>

Won't work either:
<? mysql_connect("localhost:/path/to/socket", "me","mypass"); ?>

Works (when i define sql to be LAN ip address of server):
<? mysql_connect("sql", "me","mypass"); ?>

Thats the behaviuor of mysql. Explicit address has to be given to establish a TCP connection.

If you can't connect through the socket it is definitive a configuration issue. If in doubt, upgrade to latest RC

http://www.php.net/~zeev/php-4.1.0RC3.tar.gz

Please ask such questions at php-general@lists.php.net first.

Not really a bug, bogus.
