關於SSL證書說明

博主用的DV免費證書做的測試。

關於SSL Key 和 CSR 檔案或PEM檔案

一般SSL發行商會提供給大家key或者csr。
如果沒有，可以自己生成，用OpenSSL。
.key是私鑰

配置HTTPS

首先得進入nginx主機配置目錄：/var/nginx/sites-enabled
**配置https和http有兩種方式：

• 一種是兩者共存
• 另一種是強制http跳轉https

同時監聽80和443埠

server {
    listen              80;#同時開啟80和443埠
 

    listen              443 ssl;
    server_name         example.com;
    root /var/www/html;
    index index.php index.html index.htm index.nginx-debian.html;
    #證書檔案
    ssl_certificate     example.com.crt;
    #私鑰檔案
    ssl_certificate_key example.com.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
 

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    #php解析
    location ~ \.php$ {
                include snippets/fastcgi-php.conf;

        #
        #       # With php7.0-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
        #       # With php7.0-fpm:
                fastcgi_pass unix:/run/php/php7.0
 
-fpm.sock;
        }
}

強制http跳轉https

server {
        listen 80;
        server_name example.com;
        return 301 https://$server_name$request_uri;
}
server {
    listen 443 ssl;
    server_name example.com;
    ssl on;
    root /var/www/html;
    index index.php index.html index.htm index.nginx-debian.html;
    ssl_certificate   example.com.curl;
    ssl_certificate_key  example.com.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    location / {
        root /var/www/html;
        index index.php index.html index.htm index.nginx-debian.html;
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
    }
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
                include snippets/fastcgi-php.conf;

        #
        #       # With php7.0-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
        #       # With php7.0-fpm:
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        location ~ /\.ht {
                deny all;
        }
        # deny .git access
        location ~ /\.git {
            deny all;
        }
}
