stream {

upstream 7000 {
hash $remote_addr consistent;
server 12.12.12.12:7000 max_fails=3 fail_timeout=30s;
}
upstream 7001 {
hash $remote_addr consistent;
server 12.12.12.12:7001 max_fails=3 fail_timeout=30s;
}
        upstream 7002 {
        hash $remote_addr consistent;
        server 12.12.12.12:7002 max_fails=3 fail_timeout=30s;
}
        upstream 7003 {
        hash $remote_addr consistent;
        server 12.12.12.12:7003 max_fails=3 fail_timeout=30s;
}


server {
listen 7000;
proxy_connect_timeout 1s;
proxy_timeout 3s;
proxy_pass 7000;
}

server {
listen 7001;
proxy_connect_timeout 1s;
proxy_timeout 3s;
proxy_pass 7001;
}
server {
        listen 7002;
        proxy_connect_timeout 1s;
        proxy_timeout 3s;
        proxy_pass 7002;
}
server {
        listen 7003;
        proxy_connect_timeout 1s;
