Configure IHS as reverse proxy on local or remote Linux or Windows machine with ELM using command line

Author: Abdulhusain Hamid
Build basis: ELM 7.0.2; WAS 9.0.5.1; IHS 9.0.5.1; Plugins 9.0.5.1; RHEL 7.9; Windows Server 2016.

Note: Support removed for IBM WebSphere Application Server (Traditional WAS) starting with ELM version 7.0.3. Use WebSphere Liberty, either embedded and installed with ELM applications, or separately installed

This web page will assist configuring IHS as reverse proxy on local or remote Linux or Windows machine with ELM using command line. This will cover generating IHS kdb file, adding certificate into kdb file, updating httpd.conf file, creating WAS profile, updating few properties on WAS profile, creating IHS Web Server on WAS profile and merging plugin-cfg.xml through command line.

Windows:

1. Install IHS (C:\IBM\WebSphere\HTTPServer) and WebSphere Plugin (C:\IBM\WebSphere\Plugins) on local or remote machine

Add below line in file C:\IBM\WebSphere\HTTPServer\java\8.0\jre\lib\security\java.security

   security.provider.10=com.ibm.security.cmskeystore.CMSProvider  (This step is required for ikeyman GUI tool)

2. Generate IHS_key.kdb file on IHS machine

   C:\IBM\WebSphere\HTTPServer\bin>

   gskcapicmd.bat -keydb -create -db IHS_key.kdb -pw secret -expire 365 -stash -type cms
 

3. Add certificate to it

gskcapicmd.bat -cert -create -db IHS_key.kdb  -label winserv.test.clms.com -expire 365 -dn "CN=winserv.test.clms.com" -default_cert yes -pw secret

4. Update httpd.conf at C:\IBM\WebSphere\HTTPServer\conf on IHS machine

LoadModule ibm_ssl_module modules/mod_ibm_ssl.so

Listen 0.0.0.0:443

<VirtualHost *:443>

SSLEnable

</VirtualHost>

KeyFile C:/IBM/WebSphere/HTTPServer/bin/IHS_key.kdb

SSLStashFile C:/IBM/WebSphere/HTTPServer/bin/IHS_key.sth

SSLDisable

5. Install WAS and create WAS profile. Install ELM webapps.

 
C:\IBM\WebSphere\AppServer\bin>manageprofiles.bat -create -profileName ELMSrvr -templatePath C:\IBM\WebSphere\AppServer\profileTemplates\default -profilePath C:\IBM\WebSphere\AppServer\profiles\ELMSrvr -enableAdminSecurity true -adminUserName wasadmin -adminPassword wasadmin -omitAction samplesInstallAndConfig
 
C:\IBM\WebSphere\AppServer\profiles\ELMSrvr/bin>
wsadmin.bat -lang jython -user wasadmin -password wasadmin -f C:\IBM\JazzTeamServer\server\was\clm_was_config.py   C:\IBM\JazzTeamServer\server\conf

wsadmin.bat -lang jython -user wasadmin -password wasadmin -f  C:\IBM\JazzTeamServer\server\was\clm_deploy_distributed.py  winservNode01 server1 C:\IBM\JazzTeamServer\server\webapps  qm,rm  -config  C:\IBM\JazzTeamServer\server\was

6. Update few properties on WAS profile using following commands:

C:\IBM\WebSphere\AppServer\profiles\ELMSrvr\bin>startServer.bat server1 -profileName ELMSrvr
 
C:\IBM\WebSphere\AppServer\profiles\ELMSrvr\bin>wsadmin.bat -lang jython -user wasadmin -password wasadmin -c "AdminConfig.create('Property', AdminConfig.list('WebContainer',AdminConfig.getid('/Server:server1/')), '[[name trusthostheaderport] [value true]]')"
 
C:\IBM\WebSphere\AppServer\profiles\ELMSrvr\bin>wsadmin.bat -lang jython -user wasadmin -password wasadmin -c "AdminConfig.create('Property', AdminConfig.list('WebContainer',AdminConfig.getid('/Server:server1/')), '[[name com.ibm.ws.webcontainer.extracthostheaderport] [value true]]')"

7. Create IHS Web Server on WAS profile (IHS must be installed on local or remote machine before creating IHS Web Server):

C:\IBM\WebSphere\AppServer\profiles\ELMSrvr\bin>wsadmin.bat -lang jython -user wasadmin -password wasadmin -c "AdminTask.createWebServerByHostName('[-webserverName ELMSrvr -templateName IHS -webPort 80 -serviceName IBMHTTPServerV9.0 -webInstallRoot C:\IBM\WebSphere\HTTPServer -webProtocol HTTP -configurationFile -errorLogfile -accessLogfile -pluginInstallRoot c:\IBM\WebSphere\Plugins -webAppMapping ALL -hostName winserv.test.clms.com -platform windows -adminPort 8008 -adminUserID wasadmin -adminPasswd wasadmin -adminProtocol HTTP]')"

8. Update plugin-key.kdb pwd on WAS machine: (These steps can be carried out on IHS machine too)

C:\IBM\WebSphere\AppServer\profiles\ELMSrvr\config\cells\winservNode01Cell\nodes\winservNode01\servers\ELMSrvr>C:\IBM\WebSphere\HTTPServer\bin\gskcapicmd.bat -cert -list -db plugin-key.kdb -pw WebAS

C:\IBM\WebSphere\AppServer\profiles\ELMSrvr\config\cells\winservNode01Cell\nodes\winservNode01\servers\ELMSrvr>C:\IBM\WebSphere\HTTPServer\bin\gskcapicmd.bat -keydb -stashpw -db plugin-key.kdb  -pw WebAS

C:\IBM\WebSphere\AppServer\profiles\ELMSrvr\config\cells\winservNode01Cell\nodes\winservNode01\servers\ELMSrvr>C:\IBM\WebSphere\HTTPServer\bin\gskcapicmd.bat -cert -list -db plugin-key.kdb -pw WebAS

9. Copy files from WAS machine to IHS machine

Copy files from WAS machine C:\IBM\WebSphere\AppServer\profiles\ELMSrvr\config\cells\winservNode01Cell\nodes\winservNode01\servers\ELMSrvr to IHS machine C:\IBM\WebSphere\Plugins\config\ELMSrvr

10. Update C:\IBM\WebSphere\HTTPServer\conf\httpd.conf file on IHS machine with below lines:

LoadModule was_ap24_module "C:\IBM\WebSphere\Plugins\bin\32bits\mod_was_ap24_http.dll"

WebSpherePluginConfig "C:\IBM\WebSphere\Plugins\config\ELMSrvr\plugin-cfg.xml"

11. Restart IHS using Windows Service or command line tool.

12. Verify, if IHS port 443 is listening and forwarding requests to respective ELM app.

If IHS is configured to forward requests to multiple WAS profiles, then, follow above steps for 2nd and more profiles.

13. Merge plugin-cfg.xml using following command.

C:\IBM\WebSphere\AppServer\bin>pluginCfgMerge.bat  C:\IBM\WebSphere\Plugins\config\ELMSrvr\plugin-cfg.xml   C:\IBM\WebSphere\Plugins\config\ELMSrvr2\plugin-cfg.xml   C:\IBM\WebSphere\Plugins\config\merged_plugins\plugin-cfg.xml

14. Update C:\IBM\WebSphere\HTTPServer\conf\httpd.conf file for merged profile.

LoadModule was_ap24_module "C:\IBM\WebSphere\Plugins\bin\32bits\mod_was_ap24_http.dll"

WebSpherePluginConfig "C:\IBM\WebSphere\Plugins\config\merged_plugins\plugin-cfg.xml"
