Nginx 安装 SSL 配置 HTTPS

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 0.0.0.0:22              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
