1 从http://nginx.org/en/download.html 或http://nginx.net/en/download.html
wget http://nginx.org/download/nginx-0.6.38.tar.gz
2 解压 安装：
tar zxvf nginx-0.6.38.tar.gz
cd nginx-0.6.38
./configure
make
make install
正常安装的话，这样就可以了，但是有时会出现在下面这样的提示错误：
Configuration summary
+ PCRE library is not found
+ OpenSSL library is not used
+ md5 library is not used
+ sha1 library is not used
+ using system zlib library
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre= option.
从上面的提示可以看出，需要安装PCRE库
./configure: error: SSL modules require the OpenSSL library.
You can either do not enable the modules, or install the OpenSSL library
into the system, or build the OpenSSL library statically from the source
with nginx by using --with-openssl=<path> option.
error: the HTTP rewrite module requires the PCRE library.
