在已经安装的nginx上，增加ssl模块

1. /usr/local/nginx/sbin/nginx -V 查看nginx版本与编译安装了哪些模块
nginx version: nginx/1.10.3
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments:
注意是V。v只显示版本号

2. 下载nginx 1.10.3, 并且configure
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module

3. 执行make ，千万不要make install 否则会覆盖现有的nginx

4. 关闭nginx

5. copy  ~/download/nginx-1.10.3/objs/nginx 到现有的/usr/local/nginx/sbin/nginx

6. /usr/local/nginx/sbin/nginx -V 查看编译安装的模块
nginx version: nginx/1.10.3
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled

configure arguments: --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module

7. 修改nginx.conf文件

server {
  server_name xxx.yyy.com;
  listen 443;
  ssl on;
  ssl_certificate /usr/local/nginx/conf/xxx.com_server.txt; #公钥
  ssl_certificate_key /usr/local/nginx/conf/xxx.com_private.txt; #私钥

location / {
      # location的一堆配置
      # 
      #
      # ################
  }

error_page   500 502 503 504  /50x.html;
  location = /50x.html {
      root   html;
  }
}
###########################80端口的处理###############################
server {
  listen 80;
        server_name  xxx.yyy.com;
        send_timeout 1800;

rewrite ^(.*)$  https://xxx.yyy.com$1 permanent; # 80端口跳转
}
