centos7安装nginx（gz）

1.解压下载完成的 nginx.gz 包

tar -zxvf nginx.gz 

2.进入解压好的目录执行 ./configure，如果要安装 ssl 则需要执行  ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-file-aio --with-http_realip_module

如果报错

1）error: the HTTP rewrite module requires the PCRE library.

解决办法：
yum -y install pcre-devel

2）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=<path> options.

解决办法：
yum -y install openssl openssl-devel

3.编译

make

4.安装
make install
