Hi Jim,
I am using the module of mod_proxy_hcheck in the version of 2.4.23, I have
some questiones about the configuration, but I can not find the answer in the
official website of apache and the internet because it is two young. ^_^
So the question's description:
If I put the configuration into the element of "VirtualHost", it will not work.
ProxyHCExpr ok234 {%{REQUEST_STATUS} =~ /^[234]/}
ProxyHCExpr ok23 {%{REQUEST_STATUS} =~ /^[23]/}
ProxyHCExpr in_maint {hc('body') !~ /The requested resource is not available/}
ProxyRequests Off
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot "/usr/local/apache/htdocs"
ServerName localhost
ServerAlias localhost
ProxyPass /examples balancer://cluster
ProxyPassReverse /examples balancer://cluster
ErrorLog "logs/dummy-host2.example.com-error_log"
CustomLog "logs/dummy-host2.example.com-access_log" common
ProxyHCExpr ok23 {%{REQUEST_STATUS} =~ /^[23]/}
ProxyHCExpr in_maint {hc('body') !~ /The requested resource is not available/}
ProxyRequests Off
<proxy balancer://cluster>
BalancerMember http://localhost:8181/examples loadfactor=1 hcmethod=GET
hcexpr=ok23 hcinterval=2 hcuri=/status
BalancerMember http://localhost:8282/examples loadfactor=1 hcmethod=GET
hcexpr=in_maint hcinterval=2 hcuri=/servlet
ProxySet lbmethod=byrequests
</proxy>
</VirtualHost>
But if I put the configuration out of the element of "VirtualHost", it will
work well, but also not perfect.
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot "/usr/local/apache/htdocs"
ServerName localhost
ServerAlias localhost
ProxyPass /examples balancer://cluster
ProxyPassReverse /examples balancer://cluster
ErrorLog "logs/dummy-host2.example.com-error_log"
CustomLog "logs/dummy-host2.example.com-access_log" common
</VirtualHost>
ProxyHCExpr ok234 {%{REQUEST_STATUS} =~ /^[234]/}
ProxyHCExpr ok23 {%{REQUEST_STATUS} =~ /^[23]/}
ProxyHCExpr in_maint {hc('body') !~ /The requested resource is not available/}
ProxyRequests Off
<proxy balancer://cluster>
BalancerMember http://localhost:8181/examples loadfactor=1 hcmethod=GET
hcexpr=ok23 hcinterval=2 hcuri=/status
BalancerMember http://localhost:8282/examples loadfactor=1 hcmethod=GET
hcexpr=in_maint hcinterval=2 hcuri=/servlet
ProxySet lbmethod=byrequests
</proxy>
We can see the log in the tomcat1 and tomcat2 like this:
127.0.0.1 - - [31/Jul/2016:22:23:57 +0800] "GET /examples HTTP/1.0" 302 -
127.0.0.1 - - [31/Jul/2016:22:23:59 +0800] "GET /examples HTTP/1.0" 302 -
127.0.0.1 - - [31/Jul/2016:22:24:01 +0800] "GET /examples HTTP/1.0" 302 -
It is indicated that they are sending the heartbeat request to the
tomcat(workers). But you can see that the parameter of "hcuri" also is not
affect, and this configuration does not satisfy our requirement we must put it
into the virtulhost to distinguish the other request from other port.
Jim, Can you tell me how to config them? It is very important and critical for
me, I have put in time and effort to keep this work. Thank you very much.
Best Regards
