1.重定向

• (1)服务端配置

cd /usr/local/nginx/conf/切换到nginx服务器的配置目录下
vim nginx.conf 编辑配置文件
当访问域名 www.westos.org时，实际上访问的是 /web/index.html文件
128     server {
129         listen 80;  # 监听80端口
130         server_name www.westos.org;  # 定义域名
131 
132         location / {
133             root /web;
134             index index.html;
135         }
136     }
mkdir /web建立目录
vim /web/index.html
写入www.westos.org's page

• (2)客户端测试

vim /etc/hosts做本地解析
172.25.78.11 server1   www.westos.org
curl www.westos.org     # 测试成功
得到www.westos.org's org

2.添加443端口，实现http到https的加密

需要编译ssl模块
cd nginx-1.17.1/
yum install -y openssl-devel  # 编译ssl模块需要的依赖包
 ./configure --prefix=/usr/local/nginx/  --with-http_ssl_module --with-file-aio
make && make install
cd /etc/pki/tls/certs/
make cert.pem   # 制作证书
cp cert.pem /usr/local/nginx/conf/    # 证书在 /usr/local/nginx/conf/才会生效
cd /usr/local/nginx/conf/
vim nginx.conf
     server {
         listen       443 ssl;    # 监听端口为443
         server_name  www.westos.org;
 
         ssl_certificate      cert.pem;    # 证书位置 
         ssl_certificate_key  cert.pem;    # 私钥位置
 
         ssl_session_cache    shared:SSL:1m;
         ssl_session_timeout  5m;
 
         ssl_ciphers  HIGH:!aNULL:!MD5;    # 密码加密方式
         ssl_prefer_server_ciphers  on;     
 
         location / {
             root   /web;   # 根目录位置
             index  index.html index.htm;
         }
     }
 
     server {
         listen 80;
         server_name www.westos.org;
 
         location / {
             root /web;
             index index.html;
         }
     }

/usr/local/nginx/sbin/nginx  -t  # 检测语法
/usr/local/nginx/sbin/nginx  -s reload
netstat -antlp    |   grep   443      # 查看443端口已开启

vim /etc/hosts   # 在客户端写解析
172.25.78.11   server1  www.westos.org
