查看 nginx 是否安装 http\_ssl\_module 模块。

$ /usr/local/nginx/sbin/nginx -V  # nginx -V 部分系统也可以

如上图有‘***-***\-with-http\_ssl\_module’ 这个选项，表示已经安装SSL模块。可直接进入配置nginx.conf 配置

### Nginx.conf 配置 ###

编辑 /usr/local/nginx/conf/nginx.conf 配置文件：

配置 https [server][]。注释掉之前的 http server 配置，新增 https server：

server {
        # 服务器端口使用443，开启ssl, 这里ssl就是上面安装的ssl模块
        listen       443 ssl;
        # 域名，多个以空格分开
        server_name  hack520.com www.hack520.com;
        
        # ssl证书地址
        ssl_certificate     /usr/local/nginx/cert/ssl.pem;  # pem文件的路径
        ssl_certificate_key  /usr/local/nginx/cert/ssl.key; # key文件的路径
        
        # ssl验证相关配置
        ssl_session_timeout  5m;    #缓存有效期
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;    #加密算法
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;    #安全链接可选的加密协议
        ssl_prefer_server_ciphers on;   #使用服务器端的首选算法
    
        location / {
            root   html;
            index  index.html index.htm;
        }
    }

将 http 重定向 https。

server {
        listen       80;
        server_name  hack520.com www.hack520.com;
        return 301 https://$server_name$request_uri;
    }

### 重启 nginx ###

$ /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

如果 80 端口被占用，用kill \[id\]来结束进程：

# 查看端口使用
    $ netstat -lntp
    
    Active Internet connections (only servers)
    Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
    tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      21307/nginx: master 
    tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      3072/sshd           
    tcp        0      0 0.0.0.0:443             0.0.0.0:*               LISTEN      21307/nginx: master 
    
    # 结束 80 端口进程
    $ kill 21307

再次重启 nginx：

$ /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

或者：

service nginx restart
