  • To remove Gnome from Scientific Linux, run the following command (while running outside of the GUI). This will remove all related applications related to the Gnome including Mozilla/etc. yum groupremove "GNOME Desktop Environment"
  • Next, you will need to make sure your runlevel is set to 3. Otherwise, you won't be able to boot up into text mode.

    Searching for a valid kernel header path... The path "" is not valid.
    You will need the following packages installed: gcc make kernel-headers kernel-devel The trick is that you will need to perform at least two reboots before the vmware installer will actually find the kernel header package. You can verify the kernel install using "rpm -qa kernel*"
    1. yum install gcc make kernel-headers kernel-devel
    2. yum update
    3. Reboot (shutdown -r now)
    4. Run vmware-install.pl (Ex. /tmp/vmware-tools-distrib)
    5. It will probably not find the kernel header path this time around. Cancel the installer if its unable to find it again.

If you have a site with heavy CPU and memory load in Apache, then nginx is a great choice. I recently made the switch to nginx and have noticed a reduction in CPU and memory usage. Nginx loads static content very fast and efficiently. Here's a graph of my nginx server load test. Courtesy of LoadImpact's free load testing service. The user load time on my server is minimally impacted with 50 clients viewing the site simultaneously.]]> http://albertech.net/2011/04/installing-nginx-with-php-mysql-wordpress-in-fedora/feed/ 0 FIX: Fedora SELinux permissions for PHP file upload http://albertech.net/2011/03/fix-fedora-selinux-permissions-for-php-file-upload/ http://albertech.net/2011/03/fix-fedora-selinux-permissions-for-php-file-upload/#comments Wed, 02 Mar 2011 23:27:41 +0000 admin http://albertech.net/?p=643 Command to set permissions: chcon -R -t httpd_sys_rw_content_t [Name of Folder] You can check the SELinux permissions via the following command: ls -halZ]]> http://albertech.net/2011/03/fix-fedora-selinux-permissions-for-php-file-upload/feed/ 1 Issues with Debian Lenny and Tomcat 5.5 http://albertech.net/2010/11/issues-with-debian-lenny-and-tomcat-5-5/ http://albertech.net/2010/11/issues-with-debian-lenny-and-tomcat-5-5/#comments Tue, 16 Nov 2010 01:00:21 +0000 admin http://albertech.net/?p=520 Is your Debian install of Tomcat 5.5 not working with your Webapp? Just a heads up for anyone with problems trying to get webapps working with Debian. I highly recommend installing Tomcat 6.0 from source. It helped clear a number of issues for me. Debian only supports Tomcat 5.5 in their package management system. I could have gone with unstable to get Tomcat 6.0, but I prefer not to deal with their folder organization layout (see below) Here are a few resources I've used to install Tomcat 6.0 in Debian Lenny.
      1. How to Install Tomcat 6 in Debian Lenny. This is an excellent step-by-step tutorial. A+ in my book.
      2. http://www.mysql.com/downloads/connector/j/ Connector/J, MySQL JDBC Connector download.

    9. WinSCP closes unexpectedly after authenticating
    10. Connection failure after successful authentication
    11. Client logs two attempts to connect to the /home/username home directory before failing
