Make sure the database username and password(MYSQL_PASSWORD) in /opt/fog/service/etc/config.php is the same as in /var/www/fog/commons/config.php.

Then restart the Multicast service.
[CODE]sudo /etc/init.d/FOGMulticastManager restart[/CODE]

[url]http://www.fogproject.org/wiki/index.php/Multicasting[/url]
has troubleshooting tips on the bottom of the page.

i’ve already done that. multiple times. when i get back to the computer i will post all the config setting.

[maltobelli]

Could you run the below code to verify PHP can connect to the server as it is specified in the config?

[CODE]php -r “include(‘/opt/fog/service/etc/config.php’);mysql_connect(MYSQL_HOST,MYSQL_USERNAME,MYSQL_PASSWORD) or die('I could not connect! '.PHP_EOL); echo 'I connected successfully '.PHP_EOL;”[/CODE]

If the config for MySQL is wrong it will display something like :

[CODE]PHP Warning: mysql_connect(): Access denied for user ‘fog’@‘localhost’ (using password: YES) in Command line code on line 1
I could not connect![/CODE]

Otherwise it will just display [CODE] I connected successfully[/CODE]

[brian_]

root@T412-fogserver:/# php -r “include(‘/opt/fog/service/etc/config.php’);mysql_connect(MYSQL_HOST,MYSQL_USERNAME,MYSQL_PASSWORD) or die('I could not connect! '.PHP_EOL); echo 'I connected successfully '.PHP_EOL;”
I connected successfully

[maltobelli]

Since you can get into the Web UI and start a task fine, does /opt/fog/service/etc/config.php has the same database name as /var/www/fog/commons/config.php?

If so, that’s all i can think of for now.

[brian_]

had to reinstall and now he is whats happening.
the php command listed above still works and completes successfully
when i make a group and give it a multicast task it disappears in the task listings

/opt/fog/service/etc/config.php
define( “MYSQL_HOST”, “localhost” );
define( “MYSQL_DATABASE”, “fog” );
define( “MYSQL_USERNAME”, “root” );
define( “MYSQL_PASSWORD”, “” );

/var/www/fog/commons/config.php?
define( “MYSQL_HOST”, “localhost” );
define( “MYSQL_DATABASE”, “fog” );
define( “MYSQL_USERNAME”, “root” );
define( “MYSQL_PASSWORD”, “” );

i will try the multicast by giving it the task while it’s waiting for one. that normally works.

[brian_]

now that i have fixed the mysql password and the tftp password and i now get the “I could not connect!” doing the php command

root@T412-fogserver:/# php -r “include(‘/opt/fog/service/etc/config.php’);mysql_connect(MYSQL_HOST,MYSQL_USERNAME,MYSQL_PASSWORD) or die('I could not connect! '.PHP_EOL); echo 'I connected successfully '.PHP_EOL;”
PHP Warning: mysql_connect(): Lost connection to MySQL server at ‘reading initial communication packet’, system error: 111 in Command line code on line 1
I could not connect!

define( “MYSQL_HOST”, “localhost” );

define( “MYSQL_USERNAME”, “root” );
define( “MYSQL_PASSWORD”, “824561” );

[brian_]

i tried changing the /etc/hosts

127.0.0.1 localhost
192.168.155.69 T412-fogserver

and still no luck

[maltobelli]

System error 111 is connection refused. Is your MySQL server configured to allow connections from IP’s other than 127.0.0.1? Does using define( “MYSQL_HOST”, “127.0.0.1” ); allow the PHP code to connect?

That IP should almost always be 127.0.0.1 or localhost, since each invidual client does not actually connect to the MySQL server themselves.

[brian_]

changed both configs back to 127.0.0.1 and i now get new messages in the multicast log file.

still does not work

[maltobelli]

if it isn’t working , could you also check the udpcast log , to see if clients are connecting successfully or not.

[CODE]tail -f /opt/fog/log/multicast.log.udpcast*[/CODE]

[maltobelli]

You typed in upcast, it is supposed to be udpcast.
[CODE]tail -f /opt/fog/log/multicast.log.udpcast*[/CODE]

Post #13 suggests there is an issue starting UDPcast, Is eth0 the correct interface and is not disabled? Do you have SE Linux or a firewall running?

Run this (taken from the multicast log in post #13)and see what error it gives you
[CODE] gunzip -c “/images/win7dual2/d1p1.img” | /usr/local/sbin/udp-sender --min-receivers 2 --portbase 63106 --interface eth0 --half-duplex --ttl 32 --nokbd;gunzip -c “/images/win7dual2/d1p2.img” | /usr/local/sbin/udp-sender --min-receivers 2 --portbase 63106 --interface eth0 --half-duplex --ttl 32 --nokbd;gunzip -c “/images/win7dual2/d1p3.img” | /usr/local/sbin/udp-sender --min-receivers 2 --portbase 63106 --interface eth0 --half-duplex --ttl 32 --nokbd;[/CODE]
