As a dick wire PHP programmer, then you are more or less to contact the Linux command, once we may be familiar with FreeBSD, but does not mean that we can use it, so, or honestly to share their own learning process notes, we often heard that Linux installation is very simple, But do you know how many different ways it is? Some people say that the source installation, some people say rpm package installation, some people say is the script, some people say is yum, then really have so many installs? What are the advantages and disadvantages of each? Think of all scared, can only slowly go deep, first learn to use the main, do not understand the knowledge, we have Google and Baidu, you can also take a ladder to find what you want, only you do not work hard, you do not have to do (at that time joking), said so much or application-oriented, books on the things everyone can know, But integrated practice is not necessarily everyone's ability is the same, so we still more practice!
RPM is a "Add/Remove Program" in Windows like Redhat Package Manager (Redhat Packages management tool)
RPM Execution Installation package
Binary packages (binary) and source code packages (sources) are two types. Binary packages can be installed directly on the computer, and the source code package will be automatically compiled and installed by RPM. Source code packages often use src.rpm as the suffix name.
For example: lamp environment, sometimes you will find that with the source code compiled installation lacks a lot of dependencies, for the novice, those who rely on how to solve, you may be a knot to solve, can all yum? I tell you, if you can not find that is the dynamic library, generally end with so, we could go to the relevant website to find: http://rpmfind.net/
