When trying to make a proxy balancer work in my Oracle HTTP Server (based on Apache HTTP Server 2.2), I'm running into the following error, taken from the log file:
undefined symbol: ap_proxy_set_wstatus
It's a syntax error from the httpd.worker, and says that it cannot load the mod_proxy_balancer.so module into the server. Is this an issue where I need to re-download the module? Or is there something I need to add/edit in one of the configuration files?
Some more information:
The balancer is running out of a VirtualHost, and directing traffic through 2 virtual hosts on another server.
The following code (IP and port #s changed) is in a configuration file that is included in the httpd.conf file with the include statement:
>
Listen 1000
NameVirtualHost *:1000
<Proxy balancer://balancertest>
BalancerMember http://ipaddress:0000
BalancerMember http://ipaddress:0001
lbmethod=bybusyness
</Proxy>
<VirtualHost *:7946>
ProxyPass /texthere balancer://balancertest
ProxyPassReverse /texthere balancer://balancertest
</VirtualHost>

I have a VPS host that handles a subdomain (gate.domain.eu).
Right now I have a secondary machine in a private network connected to VPN running a gitlab instance. Using vpn,and port forwarding, i managed to bring that gitlab instance to https://gate.domain.eu:8443.
How can I configure the apache server that it will point another subdomain eg(gitlab.domain.eu) to https://gate.domain.eu:8443?
The ideea is that a user should access gitlab trough gitlab.domain.eu.
I configured DNS server for gitlab.domain.eu and configured apache virtual host as follows:
<VirtualHost *:80>
ServerAdmin me#mydomain.com
ServerName gitlab.domain.eu
ProxyPreserveHost On
# setup the proxy
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
ProxyPass / https://gate.domain.eu:8443/
ProxyPassReverse / https://gate.domain.eu:8443/
</VirtualHost>
When accessing gitlab.domain.eu I get:
"Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request."
Hope someone can point me in the right direction. I've been trying to get this to work for many hours :(
Scenario - I have a DMZ where I've set up the Apache server. I need to securely talk to the internal server where I have set up another Apache server which is reverse proxied again to a localhost app within the server.. So, basically..
outside world > internet (https://app1.com) > dmz (apache reverse proxy) > internal server (apache reverse proxy - https://app1prod.com) > (http) > localhost:8080
Now, in dmz, I can directly access https://app1prod.com without issues. But, I can't for the life of me get https://app1.com to work from dmz. I get a '503 service unavailable' message :( Here is my apache config in dmz..
<VirtualHost *:443>
ServerName app1.com
ProxyRequests off
SSLProxyCheckPeerName off
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerExpire off
LogLevel debug
SSLEngine on
SSLProxyEngine on
SSLCertificateFile "xxx/cert.crt"
SSLCertificateKeyFile "xxx/key.key"
SSLCertificateChainFile "xxx/certchain.crt"
ProxyPass / https://app1prod.com/
ProxyPassReverse / https://app1prod.com/
<Proxy *>
order deny,allow
Allow from all
</Proxy>
ProxyPreserveHost on
ProxyTimeout 1200
</VirtualHost>
On my httpd.conf, I have the following modules loaded in addition to the defaults..
mod_proxy.so
mod_proxy_connect.so
mod_proxy_http.so
mod_ssl
mod_rewrite.so
mod_socache_shmcb.so
mod_ssl.so
What am I doing wrong? Please help! Thanks a lot..
Try removing ProxyPreserveHost on.
With that directive enabled, the proxied requests will be send to server defined in ProxyPass directive, but the HTTP Host: header will be preserved from initial request. In your case, the requests sent by Apache to app1prod.com will have Host: app1.com header, and app1prod.com i not configured (probably deliberately) to respond to such request.
I'm using apache2 as a local proxy balancer between the web and a jboss machine.
i've used the following configuration:
<Proxy balancer://mycluster>
BalancerMember http://localhost:8080
</Proxy>
ProxyPass /test balancer://mycluster
if i call my machine with www.mymachine.com/test then the call is passed to JBoss, but in the request it seems that it was called with 'localhost'.
how can I make sure the correct server name is passed as well?

all i needed to do is to add:
ProxyPreserveHost On
I have 3 tomcat instances running on Windows Server 2008 machine. Each one with one app:
http://host:8080/app0
http://host:8081/app1
http://host:8082/app2
How I can configure my server to map an address without the port number?
http://host/app0
http://host/app1
http://host/app2
Is it a tomcat configuration or something with DNS?
Thanks.
Ok, I tried the following:
Set up the Apache 2.2
Configure httpd.conf loading proxy modules
And add a proxy module configuration:
ProxyRequests Off
ProxyPass /app1 http://machine:8081/app
ProxyPassReverse /app1 http://machine:8081/app
<Location "/app">
Order allow,deny
Allow from all
</Location>
Now the redirect works well local in the machine. But it doesn't works when I try access from another machine in the same network. (this another machine can ping 'machine' host. And I tried putting the ip number too).
You can use nginx (http://nginx.org/en/docs/) as proxy for example.
Try simply (no load balancing etc.):
server {
listen here.your.ip:80/YourApp;
location / {
root /path/to/your/webapp;
proxy_pass http://host:8080/YourApp;
}
}
Same way for other ports
It is quite common to use multiple Tomcats behind Apache to do load balancing. While this is not load balancing the principle is the same. Instead of having one application with 3 load-balanced Tomcat workers, you would have 3 applications with 1 tomcat worker each.
You can find the tomcat documentation here: http://tomcat.apache.org/connectors-doc/
Try mod proxy configuration on below code in httpd:
ProxyPass /app0 http://localhost:8080/app0/
ProxyPassReverse /app0 http://localhost:8080/app0/
ProxyPass /app1 http://localhost:8081/app1/
ProxyPassReverse /app1 http://localhost:8081/app1/
ProxyPass /app2 http://localhost:8082/app2/
ProxyPassReverse /app2 http://localhost:8082/app2/
I am trying to setup a server with multiple web applications which will all be served through apache VirtualHost (apache running on the same server). My main constrain is that each web application must use SSL encryption. After googling for a while and looking other questions on stackoverflow, I wrote the following configuration for the VirtualHost:
<VirtualHost 1.2.3.4:443>
ServerName host.domain.org
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
SSLProxyEngine On
ProxyRequests Off
ProxyPreserveHost On
ProxyPass / https://localhost:8443/
ProxyPassReverse / https://localhost:8443/
</VirtualHost>
Even though https://host.domain.org:8443 is accessible, https://host.domain.org is not, which defeats the purpose of my virtual host configuration. Firefox complains that even though it successfully connected to the server, the connection was interrupted. Chrome return an error 107: net::ERR_SSL_PROTOCOL_ERROR.
Finally I should also mention that the virtual host works perfectly fine when I do not use SSL.
How can I make this work ?
Thanks
You don't need to configure SSL in both Apache and Tomcat.
The easiest way to accomplish that is configure SSL just on Apache and proxy to tomcat using http.
