Nginx配置免费SSL证书StartSSL,解决Firefox不信任问题

先在StartSSL上申请免费一年的SSL证书，具体过程网上很多教程。然后把申请到的key和crt文件上传到服务器，比如/usr/local/nginx/certs/.

 Nginx配置SSL证书

直接贴上我的nginx的部分配置:

 

server {

        listen 443;

    server_name   domain.com www.domain.com ;

 ssl on; ssl_certificate /usr/local/nginx/ssl/ssl.crt;

        ssl_certificate_key /usr/local/nginx/ssl/ssl.key; 



    if ($http_transfer_encoding ~* chunked) {

         return 444;

      }



    gzip on;



    if (-d $request_filename) {

        rewrite ^/(.*)([^/])$ $scheme://$host/$1$2/ permanent;

     }



     root   /home/wwwroot/;



     ssi off;

     ssi_silent_errors off;

     ssi_types text/shtml;



     location / {

         index  index.html index.htm index.shtml index.php;

         autoindex    off;

     }



    location /nginx_status {

        stub_status on;

        access_log off;

    }



     location ~ (favicon.ico) { 

         log_not_found off;

         access_log   off; 

     }



     location ~* \.(gif|jpg|jpeg|png|bmp|swf)$ {

         expires 1y;

     }



     location ~* \.(js|css)$ {

         expires 7d;

     }



    #------------

     location ~* ^(.+)\.(php[3-9]?|phtm[l]?)(\/.*)*$ {

         set $real_script_name $1.$2;

         set $path_info $3;



         if (!-f $document_root$real_script_name) {

             return 404;

         }



          fastcgi_pass 127.0.0.1:8999;

          fastcgi_param HTTPS on;

          include enable_php.conf;

     }

}

 

现在重启Nginx，Chrome应该能正常显示Https.如果只想使用Https连接，可以再添加一个server，然后跳转到https

server {

        listen 80;

    server_name   liuzhichao.com www.liuzhichao.com ;

        rewrite     ^   https://$server_name$request_uri? permanent;

}

 

 解决Firefox不信任StartSSL证书问题

wget http://cert.startssl.com/certs/ca.pem

wget http://cert.startssl.com/certs/sub.class1.server.ca.pem

cat ca.pem sub.class1.server.ca.pem >> ca-certs.crt

cat ca-certs.crt >> ssl.crt

 

再次重启Nginx，本想这下Firefox也应该能正常识别证书了，但是重启Nginx遇到了SSL: error:0906D066:PEM routines:PEM_read_bio:bad end line error错误。

[emerg]: SSL_CTX_use_certificate_chain_file("/usr/local/nginx/certs/ssl.crt")

 failed (SSL: error:0906D066:PEM routines:PEM_read_bio:bad end line error:140DC009:SSL routines:SSL_CTX_use_certificate_chain_file:PEM lib)

configuration file /usr/local/nginx/conf/nginx.conf test failed

 

这个的意思就是server.crt读取到意外错误行.这是因为我们在合并StartSSL提供的crt证书时，直接cat到了ssl.crt里。使用vi或者nano命令打开并编辑ssl.crt，找到：

-----END CERTIFICATE----------BEGIN CERTIFICATE-----

修改为：

-----END CERTIFICATE----- -----BEGIN CERTIFICATE-----

保存这个crt文件，再次重启Nginx服务，输入申请证书时私钥的密码,启动成功后，现在使用Firefox访问网站也能信任证书了。
