Merge (or Resize) the /home partition on CentOS 7

Merge (or Resize) the /home partition on CentOS 7

CentOS7 by default partitions your storage by putting a large amount of space in the /home directory partition. For most use-cases, this is perfectly fine. However, if you’re working with limited space, and have already installed a default install of CentOS, you may find you need to reclaim some of the space in your /home parition for use with other partitions. Before continuing, you will want to MAKE A BACKUP OF YOUR /HOME DIRECTORY if there’s anything in it you…

Quick Random Password Generator for Perl

Quick Random Password Generator for Perl

Mostly writing this for my own future benefit, but if this can help someone else in the process, perfect. Basically, create random strings of random sizes using random characters until the size of the resulting string is greater than 16. Pretty simple. #!/usr/bin/perl my @alphanumeric = (‘a’..’z’, ‘A’..’Z’, 0..9,’!’,’_’,’-‘); my @numeric = (0..9); my $randpassword = ”; until ( length($randpassword) > 16 ) { $randpassword = $randpassword . join ”, map $alphanumeric[rand @alphanumeric], 0..(rand @numeric); } print “$randpassword\n” Save the…

Methods to address a slow Tomcat/Railo/Lucee startup

Methods to address a slow Tomcat/Railo/Lucee startup

Recently my technicians and I encountered an issue with a hosting customer who had an interesting situation between two VPS Accounts that he owns. The first VPS had a relatively quick startup time (under a minute), and the second VPS had an extremely slow startup time (above 5 minutes). Both VM’s were relatively similar, and both served a great number of sites. The following are the two options that corrected the issue: OPTION 1 Set property in TOMCAT_HOME/conf/catalina.properties: org.apache.catalina.startup.ContextConfig.jarsToSkip=*.jar This…

Apache 2.4 – 403 Forbidden (AH01630: client denied by server configuration)

Apache 2.4 – 403 Forbidden (AH01630: client denied by server configuration)

I recently updated one of my development machines to Ubuntu 13.10 which now uses Apache 2.4 by default. In my case, I had updated a machine that was previously running Ubuntu version 13.04 and had been running Apache 2.2. After the upgrade, I was disturbed to find that none of my sites worked! I kept getting Apache 403 (Forbidden) error messages. I figured the upgrade had changed my configurations or something… but after fruitlessly messing with the config files (and…

Resetting Pulseaudio on Ubuntu 13.04 (new sound card)

Resetting Pulseaudio on Ubuntu 13.04 (new sound card)

I’ve been having a huge number of issues with both my sound and my video drivers since upgrading to Ubuntu 13.04. The problem is that my hardware is getting older, and the drivers aren’t always “up to snuff” with the latest builds. I understand that hardware evolves and in order to remain current with the latest hardware, backwards compatibility isn’t always on the top of everyone’s priority list. I’m not mad at anyone about this, but it means that I…

Making CFIDE Available to all Apache VirtualHosts

Making CFIDE Available to all Apache VirtualHosts

When working with ColdFusion on Linux, you may encounter a situation where you want to make the contents of the CFIDE folder available to all sites that are hosted on that server. The reason you might want to do this is for things like CFFORM to work properly on a host that doesn’t physically have the CFIDE directory located in that site. The solution for this is an Apache Alias. Add an alias to the Apache httpd.conf file similar to…
