nginx+php (FastCGI) +mysql installation configuration and optimization on small memory VPS (T1.MICRO)

Background information:
Previously, because the price of AWS EC2 more expensive and rented other foreign small vendors VPS, after using more than 3 years, found that the AWS EC2 Price is much cheaper than the VPS currently in use.
The T1.MICRO model of the most ideal Japanese node of the global line and speed, the choice of 3-year long-term contract price of about 2500 yuan, less than 900 yuan a year, so it is intended to move the blog to AWS EC2.
Prior to the deployment of the VPS environment, basically a complete reference to the Zhang Yi two documents, including operating system selection is the same.

But this time I want to adopt the newer CentOS 6.4 minimal x86_64.
At the same time, choose the latest version of nginx,php and MySQL, the introduction of the Epel warehouse to simplify installation and deployment of additional dependent software installation, optimize some of the original way of working, such as creating a service management script to start/stop Nginx and MySQL, Use Logrotate to cut logs and so on;
After some toss, after filling a lot of pits, finally successfully completed the deployment of a new environment, feeling very good.

Below, this is the entire installation configuration process:
1. Install Common tools
Yum install-y vim wget unzip screen tree mlocate

2. Install the Compilation tool
Yum install-y gcc gcc-c++ autoconf patch CMake Automake

3. Install Epel Warehouse

Yum install-y bzi P2 bzip2-devel ncurses ncurses-devel Curl curl-devel e2fsprogs e2fsprogs-devel unixodbc unixodbc-devel
Yum install-y Krb5-libs krb5-devel libidn libidn-devel OpenSSL openssl-devel openldap openldap-devel
Yum install-y libgcrypt LIBGCR Ypt-devel libtool
