Nginx 俄罗斯人开发的一款比较强劲的web服务器,静态页面html 单机在优化得当的情况下，能够达到3-4W的并发,是一款比较优秀的服务器软件,在国内,有Tengine【淘宝】开发的分支 ,关于Tengine的文档,可以参考,淘宝团队的官方文档：http://tengine.taobao.org/
下面介绍是在Linux Centos 6.7下关于Nginx的安装：
1.下载nginx ,目前比较常用的nginx是1.4.7，经过了历史的重重考验,下载地址：http://nginx.org/en/download.html ，选中nginx 1.4.7 下载到/usr/local/src
命令:
wget http://nginx.org/download/nginx-1.4.7.tar.gz
2.解压：

[root@alex src]# cd nginx-1.4.7
./configure --prefix=/usr/local/nginx --with-http_realip_module --with-http_sub_module --with-http_gzip_static_module --with-http_stub_status_module --with-pcre
出现错误：
./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.
错误原因，是因为缺少PCRE library 库
yum install -y net-tools pcre-devel.x86_64 gcc zlib zlib-devel make openssl-devel wget
然后重新编译,查看编译是否成功
[root@alex nginx-1.4.7]# echo $? 0
输出结果为0 ,说明是编译成功,然后Make
make之后,仍然要echo $?一下，看是否为0 ,如果不为0，注意错误原因,具体错误原因，具体分析。
最后Make install ,记得也要echo $? 一下，看是否有错误提示。
至此nginx的安装完成！
