Hi guys! I'm wrapping up a web hosting control panel written in PHP that fills up a queue with commands such as create web hosting account, or change password.
A Perl based CRON job on each server will query the database trying to determine what tasks it needs to execute. The problem however is that these jobs will run every 60s which isn't fast enough for my boss. He'd like to see things happen instantly. There are a few ways this could be accomplish that I could think of. 1) Write a daemon that queries the database for tasks only when the infinite while loop determines that the master server sent a request to begin querying the master database for tasks. 2) The CRON job could be set to run at a lower interval, maybe every 30s. 3) Write a deamon that opens a port using sockets to listen for commands and executes. 4) Using XML-RPC, construct an encrypted payload across a SSL connection to the remote server. Some of the problems I'm facing is getting a response back from the server in case there are any issues with account creation. At the moment, there is a disconnection between the master database and the web hosting servers in which if an error is generated, the user does not know believing everything is okay and an email is dispatched to the admin to check out the problem. I'm also faced with tasks that running on top of each other. Perhaps it took the server 60s to create the hosting account because the load was incredibly high. Then the second job starts up, which would be to delete the catch all account. The catch all account does not exist, but only in the database it does. I think method 1 will fix the instant change account maintenance problem, but I still can't get any responses back from the server if account creation was not successful. Method 2 will not fix the instant change, only making it quicker. Method 3 will fix the instant change and responds back if there are issues Method 4 sounds like the best method, yet I'm afraid of the script timing out and permissions issue. I don't want the remote machine running PHP that's parsing the XML payload to run with high level permissions and I hate to compile another instance of PHP and Apache. So I'm left with Method 3 with probably the best choice. Before I dive into the world of socket development, is there any recommendations or feedback? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
