Apache HTTP服务器负载均衡器

Question

I configured apache http server to act as load balancer using mod-proxy module but when i run 50 concurrent user the load is not distributing equally. All requests are going to eigher server 1 or server 2.

Is there any way to monitor the load balancer or distribute the load equally?

    ProxyRequests off
    Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED

    <Proxy balancer://executeeditchecks>

        BalancerMember http://172.50.3.6:9038/executeeditchecks route=server-044
        BalancerMember http://172.50.3.3:9038/executeeditchecks route=server-003
        ProxySet lbmethod=byrequests
        ProxySet stickysession=ROUTEID
    </Proxy>

    <Proxy balancer://editcheckexecution>

        BalancerMember http://172.50.3.6:9038/editcheckexecution route=server-044
        BalancerMember http://172.50.3.3:9038/editcheckexecution route=server-003
        ProxySet lbmethod=byrequests
        ProxySet stickysession=ROUTEID
    </Proxy>

    Listen 7070
    <VirtualHost *:7070>

    ProxyPass /executeeditchecks balancer://executeeditchecks/
    ProxyPassReverse /executeeditchecks balancer://executeeditchecks/

    ProxyPass /editcheckexecution balancer://editcheckexecution/
    ProxyPassReverse /editcheckexecution balancer://editcheckexecution/

    </VirtualHost>

You can see more details about the balancer by using the balancer manager .

see " Enabling Balancer Manager Support " at https://httpd.apache.org/docs/2.4/mod/mod_proxy_balancer.html

by adding

<Location "/balancer-manager">
    SetHandler balancer-manager
</Location>

Don't forget to set access restrictions to that url, as it is also possible to disable a worker there.
