Using load balance for thrift servers

Software load balance .
Nginx(http://nginx.org)

1.Install nginx
download source code from http://nginx.org/en/download.html

./auto/configure
make & make install

2.Install tcp module patch
developed by Yao Weibin http://yaoweibin.github.io/nginx_tcp_proxy_module/
download from GitHub http://github.com/yaoweibin/nginx_tcp_proxy_module/zipball/master

$ patch -p1 < /path/nginx_tcp_proxy_module/tcp.patch
$ ./configure --add-module=/path/nginx_tcp_proxy_module/tcp.patch
$ make & make install

3. config load balance

#check status at http://localhost:8080/status
http {
        server{
                listen 8080;
                location /status {
                        tcp_check_status;
                }
        }
}
#load balance to other server
tcp {
        upstream cluster {
                # simple round-robin
                server 192.168.0.111:11213;
                server 192.168.0.110:11213;

                check interval=3000 rise=2 fall=5 timeout=1000;

                #check interval=3000 rise=2 fall=5 timeout=1000 type=ssl_hello;

                #check interval=3000 rise=2 fall=5 timeout=1000 type=http;
                #check_http_send "GET / HTTP/1.0\r\n\r\n";
                #check_http_expect_alive http_2xx http_3xx;
        }

        server {
                listen 11113;

                proxy_pass cluster;
        }
}
                

4. Start Nginx
#start

$sudo /usr/local/nginx/sbin/nginx

#reopen

$sudo /usr/local/nginx/sbin/nginx -s reopen

#quit

$sudo /usr/local/nginx/sbin/nginx -s quit

5. note

1. each connection can be relocated to different servers with round-robin or weight.
2. one connection will not be relocated unless released.
3. other options for the optimize of nginx see the website. This is the basic usage only.
