Restrict ServerAlias domain in dispatcher based on environment

[prashanth55]

Hi All,

I have a requirement to remove one domian name from  serveralias configuration from one specific environment.

We are using 4 domain names for serverAlias configuration in vhost , but in one of the domain name is matching the stage/prod domain url then i have to remove the particular domain name from serverAlias configuration.

I tried with something like this, but it's not working.

<If "${DomainA}=='stage.domain.com'">

ServerAlias ${DomainB} ${DomaiC} ${DomainD}

</If>

<Else>

ServerAlias ${DomainA} ${DomainB} ${DomaiC} ${DomainD}

</Else>

Could any of you please suggest how to implement this requirement.

Thanks

Hi @prashanth55 ,

If you need to provide a different configuration for an environment try the following configuration.

customs.vars:

Define SERVER_ALIASES "${DomainA} ${DomainB} ${DomaiC} ${DomainD}"
<IfDefine ENVIRONMENT_STAGE>
    Define SERVER_ALIASES "${DomainB} ${DomaiC} ${DomainD}"
</IfDefine>

 vhost configuration:

ServerAlias ${SERVER_ALIASES}

Hello @prashanth55,

Not sure if it's too late to answer.

But not sure how wise it would be to write logic in vhost config, rather you can do the following: 

- Create environment specific (dev2, dev, stage, prod) .vars files as follow:

/etc/httpd/conf.d/variables/domains_${ENV_TYPE}.vars

//contains the following when: ENV_TYPE=dev2 or dev or prod
Define DOMAINS "domain_a domain_b domain_c domain_d"

//contains the following when: ENV_TYPE=stage
Define DOMAINS "domain_b domain_c domain_d"

 - Add the .vars file in the vhost as follow (on top of the file):

Include /etc/httpd/conf.d/variables/domains_${ENV_TYPE}.vars

- Add the ServerAlias in the vhost file as as follow:

ServerAlias ${DOMAINS}

Points to note here is that: for AMS the ENV_TYPE variable needs to be configured in /etc/sysconfig/httpd file in the dispatcher server and for Cloud it needs to be configured via environment variable using cloud manager.

Thanks!
