SSL Connection Configuration between Apache Web server and Weblogic server

I'm currently using Apache web server as a front end server for Weblogic server 8.1 and now i' facing some configuration problem to setting up the SSL connection between this 2 server. When i open my web application page, it shows

 

 

Failure of Server Apache bridge

 

No backend server available for connection: timed out after 10 seconds or idempotent set to OFF.

 

 

and my proxy.log shows:

Here is my step to setup the SSL connection:

 

1. Create a keystore( SSLkey.jks ) for weblogic use.

 

2. Create a certificate signing request(certreq.pem) and sent to the trusted certificate authority.

 

3. Download Root CA(rootca.cer) and signed certificate(supportcert.pem) from certificate authority.

 

4. Import rootca.cer into a custom trust key store(supporttrust.jks).

 

5. Configure the Weblogic console -> keystores and ssl -> Custom identity and custom trust.

 

6. use SSLkey.jks as custom identity keystore and supporttrust as custom trust keystore.

 

7. Extract the trusted CA file from supporttrust.jks to trustedcafile.der

 

8. Convert trustedcafile.der into trustedcafile.pem

 

9. Copy trustedcafile.pem into

 

10. Configure httpd.conf in apache

LoadModule weblogic_module modules/mod_wl_20.so

Notes: replace [ to <

[IfModule mod_weblogic.c]

WebLogicHost abc

WebLogicPort 7002

SecureProxy ON

TrustedCAFile conf/ssl/trustedcafile.pem

RequireSSLHostMatch false

Debug ALL

WLLogFile logs/proxy.log

[/Ifmodule]

[ Location /secureWebAuth]

SetHandler weblogic-handler

[/Location]

Can anyone tell me what should i do in order to correct this error? Your help is kindly appreciate!!! Please~

  • What's your traffic flow here? User -> LTM -> Apache -> Weblogic or User -> LTM -> Apache -> LTM -> Weblogic? Which parts do you want encrypted?
