How to Setup Clustered Cache


there really is not an idiots guide how to do this so I am going to try and simplify this so a newbie can understand

Step 1, firstly you need to choose yourself a port different from what you csp is using,for the cache which must be forwarded in your router and instead of tcp define it as a udp port lets say for example "15000 "

Step 2, make sure you forward this port in UDP to your CSP Server's ip address,

Step 3, in your proxy xml file locate this :



14
11




it is normally near the bottom of the xml file, don’t worry if its not exactly the same, now you are going to delete all of that and replace it, I will show with what shortly.

Step 4, you need to locate where your csp is kept, for example mine is /usr/local/csp
there also should be a cache directory, you need to open that and make a file just called " cluster "

Step 5, open / edit the new file ( cluster ) you made, in there will go your dns and port that you forwarded earlier ... ie myserver.homelinux.net :15000
also if someone has already given you details to exchange cache that would go on the next line

so you would have a file that looks like:

myserver.homelinux.net :15000
frie$$$.dyndns.addy :30001

save that file and if any other cache exchange lines are given to you they will go in there as well.

Step 6, you will need to chmod the new file ie chmod 755 /usr/local/csp/cache/cluster or whatever path your csp is in.

step 7, this will be the replacement part of the xml file that you have deleted as of step 3
now remember the udp port you have forwarded also your dns you put in the cluster file and also the path where the cluster file is.

myserver.homelinux.net
15000
file:///usr/local/csp/cache/cluster

true
true




save the xml " save changes "

Step 8, Restart your CSP Proxy

that's all

to check if it works , go to Status page and you should see Cache-Handler: com.bowman.cardserv.ClusteredCache
click on it and it opens up. you should see something like the example below


avg-received-bytes/s: 113
avg-sent-bytes/s: 292
cache-peers: 3
cached-ecms: 73
instant-hits: 893
pending-ecms: 6

received-discarded: 15322
received-pending: 30190

sent-cached: 15895

but first i will explain my setup here.

i have 1 pc machine with 3 separate CSP proxys running all in same local machine


usr/local/csp1
usr/local/csp2
usr/local/csp3

all under same IP machine example ip 192.168.0.10

so i have created the following:

1- created in usr/local  a folder called  clusteredcache
2- changed attributes from clusteredcache folder to 755
3- inside clusteredcache folder , i created a file called cluster.



So then in each csp FOLDER i routed this way this is cache config from


 
 CSP1

      true
      false    
   

then in the /usr/local/clusteredcache/cluster file i input the following

Quote

192.168.0.10:12111
192.168.0.10:12121
192.168.0.10:12131

So with this config i am getting the error on top


i also tried changing the local-host to this

You are not allowed to view links. Register or Login


and on the cluster file  like this

Quote

You are not allowed to view links. Register or Login
You are not allowed to view links. Register or Login
You are not allowed to view links. Register or Login

and i still get same error after i save and try to restart CSP and csp wont restart.

so any help or comments are appreciated guys.

as i have the 3 CSPs running in separate folders but still on the same PC machine under the same LAN ip 192.168.0.10

by the way i am running the lastest 0.9.1 svn201 build compiled direct from SVN  

i have compiled other versions also and still get same error

Hello the frie$$$ too jai them already this error message for you given advice not to take the latest version of CSP-svn Beug it has not resolved it should be before the last R200 and not R201
 here is the link directly compiled: svn co You are not allowed to view links. Register or Login @ 200 CSP-svn200

voila tu le méne dans /usr/local/CSP/cache/cluster=== attribu 755 dans le fihier cluster tu met ton host:port ==> du cache UDP
myserver.homelinux.net:15000
peers-Ă©change.dyndns:12000
 
Par contre pour 3 CSP sur la meme machine cest impeux trop car confli IP Oblige tu aurra que des problém l'échange ce fait mieux avec l'exterieur de ton réseaux local ,,tien nous informé de la suite ok @@@+

hello iam trying to make it work but never worked....
i did exact how this was explain....but always getting this error
Can some one help me please!!
