Re: Can't start MYSQL on Linux
Dear Ling, Thank you so much. Can I ask why? you have to keep in mind that the mysqld (that's the MySQL server, or the daemon) is the only one that must have read/write access to datadir (the database directories). On your machine, /var/lib/mysql/ is datadir, and mysqld will run as user mysql by default. If mysql is the owner of the datadir directories and files, mysqld will have read/write access to your databases and tables, otherwise it has not.

Re: Can't start MYSQL on Linux
Dear Wang, /usr/libexec/mysql: Can't find file './mysql/host.frm' (errno: 13) It's tricky, but you have to install the two databases (mysql and test) shipped along with the MySQL distribution. Here's that part: shell ./scripts/mysql_install_db And here's the manual part: http://www.mysql.com/doc/P/o/Post-installation.html Regards, -- Stefan Hinz Geschäftsführer / CEO iConnect e-commerce solutions GmbH # www.js-webShop.com www.iConnect.de # Gustav-Meyer-Allee 25, 13355 Berlin # Tel: +49-30-46307-382 Fax: +49-30-46307-388 - Original Message - From: Ling Wang [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, August 07, 2001 4:02 AM Subject: Can't start MYSQL on Linux I have a fresh installed Linux 7.1 from Redhat.

Re: Can't start MYSQL on Linux
I have to login as root user to do mysql_install_db and safe_mysqld . Otherwise I will get permission denied message. How come when I type service mysqld start, Linux says command not found? I could not find the command chkconfig either. Your idea does not work for me. Thanks anyhow.
