http - set frontend_ip as source IP for backend -


i have server multiple ip configured on ( virtual ip on eth0). i'm using haproxy load balacing. each ip has been configured/pointed different domain name , requests comes each ip address being forwarded different backend server using haproxy.

issue here, outgoing traffic haproxy pass through main interface ip [ default]. wanted set source ip backend connection.

i tried below config, not working. idea ?

backend  web1        server ss2 10.11.12.13:80 source ${frontend_ip}   frontend new1        bind 10.11.13.15:8080        mode tcp        use_backend web1

you have 1 ip in question can't sure. if have multiple virtual ips , want serve different backends, need create 1 frontend each @ least. this:

frontend new1     bind 10.11.13.15:80     ...     acl is_new1domain hdr(host) -i new1.domain.com     use_backend web1 if is_new1domain  frontend new2     bind 10.11.13.16:80     ...     acl is_new2domain hdr(host) -i new2.domain.com     use_backend web2 if is_new2domain  backend web1     ...     source 10.124.13.15  backend web2     ...     source 10.124.13.16

actually, if don't have other rules parse, use layer4 proxy/balance. this:

listen new1     bind 10.11.12.15:80     server ss1 10.11.12.90:8080 check     server ss2 10.11.12.91:8080 check     server ss3 10.11.12.92:8080 check     source 10.124.12.15  listen new2     bind 10.11.12.16:80     server ss4 10.11.12.80:8080 check     server ss5 10.11.12.81:8080 check     server ss6 10.11.12.82:8080 check     source 10.124.12.16

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
