Using Apache with Suexec on Linux: ON: 2007-09-07 14:50:36; When you're running an Apache Web server for yourself, you don't think about the user that's running the Apache server itself (typically nobody on Linux systems). But what if you're an ISP with multiple companies being hosted on your system? Or an educational institution with faculty who want to be able to execute their own scripts? Either everything has to be accessible to the Apache nobody user, or you have to run multiple instances of Apache on multiple ports and IP addresses, one of each per user, with the concomitant confusion of configuration files. The solution is the use of the suexec wrapper, which is part of the Apache distribution.; 6 times | category: [Security]
