安装过程

从 http://nginx.org/download/nginx-1.9.15.tar.gz 下载nginx包(或者wget http://nginx.org/download/nginx-1.9.15.tar.gz直接在Linux上用命令下载)
解压并转到目录下

tar -zxvf nginx-1.9.15.tar.gz cd nginx-1.9.15
设置一下配置信息 ./configure --prefix=/usr/local/nginx ，或者不执行此步，直接默认配置
编译安装

make make install

make的过程是把各种语言写的源码文件，变成可执行文件和各种库文件;
make install是把这些编译出来的可执行文件和库文件复制到合适的地方。

可能出现错误

在配置信息./configure --prefix=/usr/local/nginx 的时，出现错误：

/configure: error: the HTTP rewrite module requires the PCRE library.

解决方法：安装pcre

yum -y install pcre pcre-devel

-y 是跳过所有需要手动确认的环节

缺少ssl错误，错误信息如下：

./configure: error: the HTTP cache module requires md5 functions from OpenSSL library. You can either disable the module by using --without-http-cache option, or install the OpenSSL library into the system, or build the OpenSSL library statically from the source with nginx by using --with-http_ssl_module --with-openssl= options.

解决方法：安装openssl

yum -y install openssl openssl-devel

缺少编译器，错误信息如下：

./configure: error: C compiler cc is not found

解决方法：安装gcc-c++

yum -y install gcc-c++ autoconf automake

autoconf是自动配置，automake是自动编译

缺少zlib包，错误信息如下：

./configure: error: the HTTP gzip module requires the zlib library. You can either disable the module by using –without-http_gzip_module option, or install the zlib library into the system, or build the zlib library statically from the source with nginx by using –with-zlib= option.

解决方法：安装zlib

yum install -y zlib-devel

安装完成后启动

安装成功后 /usr/local/nginx 目录下如下

fastcgi.conf            koi-win             nginx.conf.default
