Linux CentOS Yum installation lamp environment

CentOS 6.5

1.yum Installation and source code compilation in the use of the time no difference, but the installation process is very different, yum only need 3 commands to complete, the source code needs 13 packages, but also have to compress the compilation, the steps are cumbersome, and as sometimes error, source code compiled installation takes about 2 hours, The advantage is that you can configure your own address and other parameters, Yum installed half an hour to fix, generally do not make mistakes, update is also very convenient.

2. My machine is the CentOS release 5.9 64 for the system, the general machine with the Yum command, and the Yum package is available, that is, you do not download things, directly yum-y install after the installation of the software you need to install, he will automatically download automatic installation, Very convenient.
