Sorry if this has already been posted. It wasn't corrected on the How-To page.
On page 6
it states to install the newer zlib and I came to a brick wall with error message: cc: Command not found
. It turns out that C+ compiler wasn't install by default and I wasn't instructed to install it before reaching this stage. To solve the problem, just run the following command.
yum install gcc-c++
Once you have C+ compiler installed clean the zlib directory and re-run configure.
The second thing I wanted to point out is that you do not need to download all 4 disks anymore if you only need LAMP installed. There is a much smaller single Server Disk (~594mb) that will do the job.
