Nginx: Unterschied zwischen den Versionen

Version vom 27. Mai 2014, 13:44 Uhr

some nginx hints

Logging stuff

logformat

i'm using nearly standard apache log-format, but prefixed with
the serving virtual-host in front...

log_format vhost '$server_name $remote_addr - $remote_user [$time_local] "$request" '
                 '$status $body_bytes_sent "$http_referer" '
                 '"$http_user_agent" "$http_x_forwarded_for"';

so, by stripping the vhost in the 1st field of a logline, you may simply use std. log-parsers
for logfile analysis...

enable rewrite-log

to turn on rewrite-log you will have to put these 2 statements:

server {
   [...]
   rewrite_log on;
   error_log  /var/log/nginx/error.log notice;
   [...]
}

be sure to set the 'notice' behind the error-logfile because
rewrites are logged to error-logfile with 'notice' level...

SSL stuff

hardening SSL

post snowden ssl-hardening:

ssl_prefer_server_ciphers On;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 SSLv3;
ssl_ciphers ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS;

PFS

cd /path/to/your/certs/
openssl dhparam -out dhparam.pem 2048

and edit nginx config:

ssl_dhparam /path/to/your/certs/dhparam.pem;

HSTS

HTTP Strict Transport Security.
if possible run https ONLY pages...
in post-snowden age this should be done... so add to your port-80-vhost:

server {
   [...]
   add_header Strict-Transport-Security max-age=15768000;
   return 301 https://www.traumartig.de$request_uri;
   [...]
}
