Hi!I use haproxy for balancing http request - this is better LB)! And now I tru ballancing EDIFACT files. 1st step I try just forwarding request between server GMD and server COMARCH via Haproxy. ----------Plan(How this work?)
server GMD send EDIFACT file to --> haproxy:7446, haproxy send --> to server COMARCH:7446(processed EDIFACT file) and send response to HAPROXY--> Haproxy:3038, haproxy send to --> GMD:3038 ----------------------------- --version Haproxy HA-Proxy version 1.5.1 2014/06/24 Copyright 2000-2014 Willy Tarreau <[email protected]> Build options : TARGET = linux2628 CPU = generic CC = gcc CFLAGS = -O2 -g -fno-strict-aliasing OPTIONS = Default settings : maxconn = 2000, bufsize = 16384, maxrewrite = 8192, maxpollevents = 200 Encrypted password support via crypt(3): yes Built without zlib support (USE_ZLIB not set) Compression algorithms supported : identity Built without OpenSSL support (USE_OPENSSL not set) Built without PCRE support (using libc's regex instead) Built with transparent proxy support using: IP_TRANSPARENT IPV6_TRANSPARENT IP_FREEBIND Available polling systems : epoll : pref=300, test result OK poll : pref=200, test result OK select : pref=150, test result OK Total: 3 (3 usable), will use epoll. -- Config haproxy global # daemon maxconn 10240 debug log 127.0.0.1 local1 debug stats socket /opt/haproxy/gmd_bscs_prod/socket_s1cm1/haproxy.sock mode 06 00 level admin log-tag haproxy #nbproc 4 defaults mode tcp log global option tcplog timeout connect 50s timeout client 30s timeout server 30s frontend gmdcom1 bind 10.254.13.100:7446 default_backend comarch mode tcp log global option tcplog # frontend gmdrrs1 bind 10.254.13.100:3038 default_backend gmdrrs mode tcp log global option tcplog backend comarch balance roundrobin mode tcp server mdsp_7446 10.254.13.40:7446 check port 7446 backend gmdrrs balance roundrobin mode tcp server rrs_3038 s1cm1t:3038 check port 3038 -------------- Debug log Haproxy Available polling systems : epoll : pref=300, test result OK poll : pref=200, test result OK select : pref=150, test result FAILED Total: 3 (2 usable), will use epoll. ......................... 0 sessions requeued, 0 total in queue. 00000000:gmdcom1.accept(0005)=0008 from [10.254.62.75:60287] 00000000:comarch.srvcls[0008:0009] 00000000:comarch.clicls[0008:0009] 00000000:comarch.closed[0008:0009] 00000001:gmdrrs1.accept(0007)=0008 from [10.254.13.40:21481] 00000001:gmdrrs.srvcls[0008:0009] 00000001:gmdrrs.clicls[0008:0009] 00000001:gmdrrs.closed[0008:0009] 00000002:gmdcom1.accept(0005)=0008 from [10.254.62.75:60292] 00000002:comarch.srvcls[0008:0009] 00000002:comarch.clicls[0008:0009] 00000002:comarch.closed[0008:0009] 00000003:gmdrrs1.accept(0007)=0008 from [10.254.13.40:21482] 00000003:gmdrrs.srvcls[0008:0009] 00000003:gmdrrs.clicls[0008:0009] 00000003:gmdrrs.closed[0008:0009] 00000004:gmdcom1.accept(0005)=0008 from [10.254.62.75:60340] 00000004:comarch.srvcls[0008:0009] 00000004:comarch.clicls[0008:0009] 00000004:comarch.closed[0008:0009] 00000005:gmdrrs1.accept(0007)=0008 from [10.254.13.40:21484] 00000005:gmdrrs.srvcls[0008:0009] 00000005:gmdrrs.clicls[0008:0009] 00000005:gmdrrs.closed[0008:0009] 00000006:gmdcom1.accept(0005)=0008 from [10.254.62.75:60467] 00000006:comarch.srvcls[0008:0009] 00000006:comarch.clicls[0008:0009] 00000006:comarch.closed[0008:0009] 00000007:gmdrrs1.accept(0007)=0008 from [10.254.13.40:21503] 00000007:gmdrrs.srvcls[0008:0009] 00000007:gmdrrs.clicls[0008:0009] 00000007:gmdrrs.closed[0008:0009] 00000008:gmdcom1.accept(0005)=0008 from [10.254.62.75:60700] 00000008:comarch.srvcls[0008:0009] 00000008:comarch.clicls[0008:0009] 00000008:comarch.closed[0008:0009] 00000009:gmdrrs1.accept(0007)=0008 from [10.254.13.40:21521] 00000009:gmdrrs.srvcls[0008:0009] 00000009:gmdrrs.clicls[0008:0009] 00000009:gmdrrs.closed[0008:0009] 0000000a:gmdcom1.accept(0005)=0008 from [10.254.62.75:60729] 0000000a:comarch.srvcls[0008:0009] 0000000a:comarch.clicls[0008:0009] 0000000a:comarch.closed[0008:0009] 0000000b:gmdrrs1.accept(0007)=0008 from [10.254.13.40:21522] 0000000b:gmdrrs.srvcls[0008:0009] 0000000b:gmdrrs.clicls[0008:0009] 0000000b:gmdrrs.closed[0008:0009] 0000000c:gmdcom1.accept(0005)=0008 from [10.254.62.75:63061] 0000000c:comarch.srvcls[0008:0009] 0000000c:comarch.clicls[0008:0009] 0000000c:comarch.closed[0008:0009] 0000000d:gmdrrs1.accept(0007)=0008 from [10.254.13.40:21604] 0000000d:gmdrrs.srvcls[0008:0009] 0000000d:gmdrrs.clicls[0008:0009] 0000000d:gmdrrs.closed[0008:0009] 0000000e:gmdcom1.accept(0005)=0008 from [10.254.62.75:64621] 0000000e:comarch.srvcls[0008:0009] 0000000e:comarch.clicls[0008:0009] 0000000e:comarch.closed[0008:0009] 0000000f:gmdrrs1.accept(0007)=0008 from [10.254.13.40:21758] 0000000f:gmdrrs.srvcls[0008:0009] 0000000f:gmdrrs.clicls[0008:0009] 0000000f:gmdrrs.closed[0008:0009] -------------------------log GMD server (application what send EDIFACT files) -
