Couchbase Server
1

I’m new to Couchbase and Nginx. I’m tyring to setup Couchbase for memcached. I’m using nginx srcache to get docs from memcached bucket. I’m able to connect to the bucket fine but i’m unable to get results through curl. Please help

here’s my nginx config

 upstream memtest {
     server memcached.server.com:11202;
     keepalive 10;
 }

server {
 listen 8080;

 location = /memc {
     internal;

     set $memc_key $query_string;
     set $memc_exptime 300;

 }

 location /testbucket {
     set $key $uri$args;
     srcache_fetch GET /memc $key;
     srcache_store PUT /memc $key;
     srcache_store_statuses 200 301 302;
     proxy_pass http://testbucket;

     # proxy_pass/fastcgi_pass/drizzle_pass/echo/etc...
     # or even static files on the disk
 }

 }

nginx.server # nc -v $HOSTNAME 11202 <<< version
Ncat: Version 7.50 ( https://nmap.org/ncat )
Ncat: Connected to nginx.server:11202.
