Topic: Apche server is failing to start after configuring mod_jk.so

[shashi.kumar@gmail.com]

Hi Everyone,

I need help from all. I have an Apache server 2.2.23 running on REHL 64 bit. I have 3 tomcat instances running on the same server.i wanted to connect my Apache with tomcat, for that i had downloaded mod_jk connecter from Apache version 1.2.37. I build the connector from source on the server and got mod_jk.so and configured the same in httpd.conf to load mod_jk and also did the configuration for worker.properties file. But after that when i tried to start the server it gives me the following error:
“httpd: Syntax error on line 148 of /etc/httpd/conf/httpd.conf: Cannot load /etc/httpd/modules/mod_jk.so into server: /etc/httpd/modules/mod_jk.so: undefined symbol: ap_get_server_description”


Note: I have checked the permissions on the mod_jk.so,no problem with it.

Please advise, i am not able to find any clue on this.javascript:emoticon('')

Thanks in advance
Shashi.

You sure you have 2.2.23 and not 2.2.3-xxxxx. Some Linux distros have odd versions of Apache. They use a version to start with and then just patch as they see the need.

ap_get_server_description() is Apache 2.2.4 & up. This should have erred during compile.

Hi Smith,

Thanks, That was one of the issue, I had apache 2.2.3.el5 running as RPM package. Moreover i had a incorrect version of mod_jk. Once both were fixed issue was resolved.

Thanks a lot again,that was really helpful clue.

Thanks,
Shashi.
