安装很简单，这里记录只是为了记下下载地址：
A、[root@localhost soft]# wget http://nginx.org/download/nginx-1.4.2.tar.gz
B、[root@localhost soft]# tar -xvf nginx-1.4.2.tar.gz && cd nginx-1.4.2
C、[root@localhost nginx-1.4.2]# ./configure
报错如下：
./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=<path> option.
解决方法： [root@localhost nginx-1.4.2]# yum install pcre-devel -y
ps：装软件就是缺什么装什么，很简单
D、[root@localhost nginx-1.4.2]# make && make install
E、[root@localhost sbin]# /usr/local/nginx/sbin/nginx
F、done
