php - Global Traffic Director - On DO droplet with Ubuntu, LAMP and Nginx help needed -


i have been trying follow digital ocean following exemple: https://www.digitalocean.com/community/tutorials/how-to-use-nginx-as-a-global-traffic-director-on-debian-or-ubuntu

having set droplet ubuntu , there lamp stack already.

despite having configured on top of lamp stack nginx try use geoip database, when run test.php file has in following code:

 <?php      if (getenv(http_x_forwarded_for)) {         $sname = getenv(server_name);         $sipaddress = getenv(server_addr);         $pipaddress = getenv(http_x_forwarded_for);         $ipaddress = getenv(remote_addr);         echo "$sname server has address : $sipaddress";         echo "<br />\n";         echo "your proxy ip address : ".$pipaddress. " (via $ipaddress) " ;     } else {         $servername = getenv(server_name);         $serveripaddress = getenv(server_addr);         $ipaddress = getenv(remote_addr);         echo "$servername server has address : $serveripaddress";         echo "<br />\n";         echo "your ip address : $ipaddress";     }     $country = getenv(geoip_country_name);     $country_code = getenv(geoip_country_code);     echo "<br/>your country : $country ( $country_code ) "; ?>

i following response live:

www.mydomain.com server has address : 12.34.56.78 ip address : 87.65.43.21 country : ( )

as can see ip address correct shows php works fine unfortunately none of geoip variables working despite being locally present.

so question have are:

  • where did screw up?
  • how come geoip data not passing through nginx?

here steps took configure servers.

i renamed default config file /etc/nginx/sites-available domain name , made sure create new link in /etc/nginx/sites-enabled.

then config file looks @ moment:

map $geoip_city_continent_code $closest_server {   default eu.mydomain.com;        us.mydomain.com;        as.mydomain.com; }  server {  server_name mydomain.com             www.mydomain.com             eu.mydomain.com             us.mydomain.com             as.mydomain.com;  if ($closest_server != $host) {   rewrite ^ $scheme://$closest_server$request_uri break; }  listen 80 eu.mydomain.com; listen [::]:80 eu.mydomain.com ipv6only=on;  root /var/www/html; index index.html index.htm;  # make site accessible http://localhost/ server_name localhost;

the end goal have 3 servers ( usa, europe, asia ), have eu 1 being central , reroute closest server using either: us.mydomain.com or eu.mydomain.com or as.mydomain.com

i hope clear enough pointers great!

thank time.

i ended using lemp stack instead when building droplet , spotted missing information digital ocean documents follows:

add both of these lines in /etc/nginx/nginx.conf file:

  • geoipcountry /usr/share/geoip/geoip.dat;
  • geoipcity /usr/share/geoip/geolitecity.dat;

then in /etc/nginx/fastcgiparams add @ end:

fastcgiparam redirectstatus 200; fastcgiparam geoipaddr $remoteaddr; fastcgiparam geoipcountrycode $geoipcountrycode; fastcgiparam geoipcountryname $geoipcountryname; fastcgiparam geoipregion $geoipregion; fastcgiparam geoipregionname $geoipregionname; fastcgiparam geoipcity $geoipcity; fastcgi_param geoip_city_continent_code $geoip_city_continent_code; #edit fastcgiparam geoipareacode $geoipareacode; fastcgiparam geoiplatitude $geoiplatitude; fastcgiparam geoiplongitude $geoiplongitude; fastcgiparam geoippostalcode $geoippostal_code;

then in /etc/nginx/sites-available/default distinction between each servers within default files handled @ map $geoipcountrycode $closest_server { level follows:

edits!!

us server:

map $geoip_city_continent_code $closest_server {   default www.yourdomain.com;    af      eu.yourdomain.com;  #africa        as.yourdomain.com;  #asia   eu      eu.yourdomain.com;  #europe   # na      www.yourdomain.com;  #north america   oc      as.yourdomain.com;  #oceania   # sa      www.yourdomain.com;  #south america }

europe server: 

map $geoip_city_continent_code $closest_server {   default eu.yourdomain.com;    # af      eu.yourdomain.com;  #africa        as.yourdomain.com;  #asia   # eu      eu.yourdomain.com;  #europe   na      www.yourdomain.com;  #north america   oc      as.yourdomain.com;  #oceania   sa      www.yourdomain.com;  #south america }

asia server :

map $geoip_city_continent_code $closest_server {   default as.yourdomain.com;    af      eu.yourdomain.com;  #africa   #      as.yourdomain.com;  #asia   eu      eu.yourdomain.com;  #europe   na      www.yourdomain.com;  #north america   # oc      as.yourdomain.com;  #oceania   sa      www.yourdomain.com;  #south america }

and should it...

you can test setup adding test.php file has following code in body:

<?php if (getenv(httpxforwardedfor)) {   $pipaddress = getenv(httpxforwardedfor);   $ipaddress = getenv(remoteaddr);   echo "your proxy ip address : ".$pipaddress. " (via $ipaddress) " ; } else {   $ipaddress = getenv(remoteaddr);   echo "your ip address : $ipaddress"; } $country = getenv(geoipcountryname); $countrycode = getenv(geoipcountrycode); $geoip_city_continent_code = getenv(geoip_city_continent_code); echo "<br/>your country : $country ( $countrycode ) "; echo "<br/>your continent : $geoip_city_continent_code "; ?>

which should return this:

your ip address : 12.34.56.78 country : united states ( ) continent : na

if in usa , reroute www.yourdomain.com etc....

edit 2 - multisite handling

this structured serve different servers country code subdomain in case us.domain.com server...

map $geoip_city_continent_code $closest_server {   af      eu.domain.com;  #africa        as.domain.com;  #asia   eu      eu.domain.com;  #europe   na      us.domain.com;  #north america   oc      as.domain.com;  #oceania   sa      us.domain.com;  #south america }  # retoute http://domain.com , http://www.domain.com http://us.domain.com server {    listen 80 default_server; # 1 of local domains other wise others should be: listen 80;   listen [::]:80 default_server ipv6only=on; # 1 of local domains other wise others should be: listen [::]:80;    server_name domain.com               www.domain.com;    return 301 http://us.domain.com$request_uri; }  # handles server {   listen 80;   listen [::]:80;    root /var/www/domain.com/html;   index index.php index.html index.htm;    # make site accessible http://localhost/   server_name  us.domain.com;    # firs part of dual condition check.   # checks in incoming host (us.domain.com) not equal $closest_server depending on contry code   if ($closest_server != $host) {     set $test  a;   }    #second part of dual condition checks incoming host us.domain.com same server_name there no messing around other domain names   if ($host ~* $server_name) {     set $test  "${test}b";   }    # checks above 2 conditions met , if redirect other global server appropriate subdomain eu.domain.com or whatever set   if ($test = ab) {     rewrite ^ $scheme://$closest_server$request_uri break;   }    # otherwise @ closest server , serve data   location / {     try_files $uri $uri/ =404;   }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
