Hello,
Apache must be hidden behind Zen using private network. So they are not
exposed over the internet.
Using HTTP farm, you can create one service per virtual host, having each
any number of frontend (can be different).
Then you can set in maintenance one apache for 1 virtual host.
By default you will then only see private of zen LB in apache log. But you
can still have true client IP with this:
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\""
combined
LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\"
\"%{User-Agent}i\"" proxy
SetEnvIf X-Forwarded-For "^.*\..*\..*\..*" forwarded
CustomLog "logs/www_access_log" proxy env=forwarded
This will also hide all check_http done by zen to check health
for 503 error, I guess it's a config error. Maybe related to https?
