Can I configure a subdomain to point to a specific port on my server

Question

I have an old computer which I converted into a minecraft server   I have 2 minecraft servers running simultaneously  one on port 25565  default  and one on port 25566     I bought the domain something com and pointed it to my server   Right now  in the game you type something com to get into the first server and something com 25566 to get into the other server   Is there a way to set one something com to point to the first server and two something com to point to the second server   I own the  centos  server  have root access  and everything else   The domain is controlled by no-ip if that makes a difference   I know that DNS has no relationship to port numbers but if there a program I can install to make this work   Thanks

I    don t think so  You can redirect the subdomain  such as blah something com  to point to something com 25566  but I don t think you can actually set up the subdomain to be on a different port like that  I could be wrong  but it d probably be easier to use a simple  htaccess or something to check   HTTP HOST  and redirect according to the subdomain

If you only got one IP on the server  there is no chance to do that  DNS is a simple name to number  IP  resolver  If you have two IPs on the server  you can point each subdomain to each of the IP-addresses and run both servers on the default port on each IP  one example com -  127 0 0 1  server  127 0 0 1 25565  two example com -  127 0 0 2  server  127 0 0 2 25565

If you have access to SRV Records  you can use them to get what you want     E G  A Records  Name  mc1 domain com Value   lt yourIP gt   Name  mc2 domain com Value   lt yourIP gt    SRV Records  Name   minecraft  tcp mc1 domain com Priority  5 Weight  5 Port  25565 Value  mc1 domain com  Name   minecraft  tcp mc2 domain com Priority  5 Weight  5 Port  25566 Value  mc2 domain com   then in minecraft you can use     mc1 domain com which will sign you into server 1 using port   25565   and     mc2 domain com which will sign you into server 2 using port   25566   then on your router you can have it point 25565 and 25566 to the machine with both servers on and Voil     Source  This works for me running 2 minecraft servers on the same machine with ports 50500 and 50501

If you wish to use 2 subdomains to other ports  you can use Minecraft s proxy server  it means BungeeCord  Waterfall  Travertine      and bind subdomain to specifiend in config yml server  To do that you have to setup your servers in BungeeCord s config  servers    pvp      motd   A Minecraft Server PVP      address  localhost 25566     restricted  false   skyblock      motd   A Minecraft Server SkyBlock      address  localhost 25567     restricted  false  Remember  Ports must be diffrent than default Minecraft s port  it means 25565   because we will use this port to our proxy  sub1 domain com and sub2 domain com we have to bind to server where you have these servers  Now  we have to bind subdomains in your Bungee server  listeners      forced hosts        sub1 domain com  pvp       sub2 domain com  skyblock       domain com  pvp    You can bind other domains to same servers   Remember to change force default server to true  and change host to 0 0 0 0 25565 Example of BungeeCord s config yml with some servers  https   pastebin com tA9ktZ6f Now you can connect to your pvp server on sub1 domain com and connect to skyblock on sub2 domain com  Don t worry  BungeeCord takes only 0 5GB of RAM for 500 players

If you want to host multiple websites in a single server in different ports then  method mentioned by MRVDOG won t work  Because browser won t resolve SRV records and will always hit  80 port  For example if your requirement is   site1 domain com maps to domain com 8080 site2 domain com maps to domain com 8081   Because often you want to fully utilize the server space you have bought  Then you can try the following   Step 1  Install proxy server  I will use Nginx here   apt-get install nginx   Step 2  Edit  etc nginx nginx conf  file to add the port mappings  To do so  add the following lines   server       listen 80      server name site1 domain com       location             proxy pass http   localhost 8080              server       listen 80      server name site2 domain com       location             proxy pass http   localhost 8081               This does the magic  So the file will end up looking like following   user www-data  worker processes auto  pid  run nginx pid  include  etc nginx modules-enabled   conf   events       worker connections 768        multi accept on     http                 Basic Settings             sendfile on      tcp nopush on      tcp nodelay on      keepalive timeout 65      types hash max size 2048        server tokens off         server names hash bucket size 64        server name in redirect off       include  etc nginx mime types      default type application octet-stream                SSL Settings             ssl protocols TLSv1 TLSv1 1 TLSv1 2    Dropping SSLv3  ref  POODLE     ssl prefer server ciphers on                Logging Settings             access log  var log nginx access log      error log  var log nginx error log                Gzip Settings             gzip on         gzip vary on        gzip proxied any        gzip comp level 6        gzip buffers 16 8k        gzip http version 1 1        gzip types text plain text css application json application javascript text xml application xml application xml rss text javascript                Virtual Host Configs        server       listen 80      server name site1 domain com       location             proxy pass http   localhost 8080              server       listen 80      server name site2 domain com       location             proxy pass http   localhost 8081                  include  etc nginx conf d   conf      include  etc nginx sites-enabled         mail         See sample authentication script at        http   wiki nginx org ImapAuthenticateWithApachePhpScript          auth http localhost auth php        pop3 capabilities  TOP   USER         imap capabilities  IMAP4rev1   UIDPLUS          server           listen     localhost 110          protocol   pop3          proxy      on               server           listen     localhost 143          protocol   imap          proxy      on             Step 3  Start nginx    etc init d nginx start   Whenever you make any changes to configuration  you need to restart nginx    etc init d nginx restart  Finally  Don t forget to add A records in your DNS configuration  All subdomains should point to domain  Like this    Put your static ip instead of 111 11 111 111  Further details    http   tutorials jenkov com nginx index html Redirect subdomain to port  nginx flask  https   serverfault com questions 920534 nginx-proxy-subdomains-to-other-addresses-and-ports

With only 1 IP you can forget DNS but you can use a MineProxy because the handshake packet of the client contains the host that then he connected to and a MineProxy will ready this host and proxy the connection to a server that is registered for that host
