RE: check for server start
a quick fix would be to see if the default port is open or not...something like: netstat -an | grep 3306 you could put that in a shell script and do all sorts of tests against it. -OR- you could use mysqladmin and whatever flag used to check status. hope this helps. ~rob -Original Message- From: Aaron Brick [mailto:[EMAIL PROTECTED]] Sent: Friday, January 11, 2002 1:01 PM To: [EMAIL PROTECTED] Subject: check for server start hi all, in debian, the /etc/init.d/mysql script waits for the appearance of /var/run/mysqld/mysqld.pid to conclude that the server has started. since the red hat init script does not do that, my program's own installer has to. however we have had a report that waiting for the pidfile is not enough; that the server wasn't ready for connections even after the file appeared. is that possible, and how can we (in sh) better determine when the server is up and ready? thanks, aaron brick. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
