Appian 18.3 installation issue - Configure Apache with Appian

Nilesh Raman

Hi All,

I have installed Appian 18.3 on one of the linux machine. Appian and tomcat configured properly and all the services started successfully. But when configuring Apache webserver with Appian I am not able to start the Apache services. I followed each and every step thoroughly as per the documentation "docs.appian.com/.../Configuring_Apache_Web_Server_with_Appian.html" but getting below error:

[core:notice] [pid 9513] SELinux policy enabled; httpd running as context system_u:system_r:httpd_t:s0

 [suexec:notice] [pid 9513] AH01232: suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)

[ssl:warn] [pid 9513] AH02292: Init: Name-based SSL virtual hosts only work for clients with TLS server name indication support (RFC 4366)

[jk:warn] [pid 9513] No JkLogFile defined in httpd.conf. Using default /etc/httpd/logs/mod_jk.log

 [jk:warn] [pid 9513] No JkShmFile defined in httpd.conf. Using default /etc/httpd/logs/jk-runtime-status

 [jk:emerg] [pid 9513] Initializing shm:/etc/httpd/logs/jk-runtime-status.9513 errno=13. Unable to start due to shared memory failure.

[jk:emerg] [pid 9513] Initializing shm:/etc/httpd/logs/jk-runtime-status.9513 errno=13. Unable to start due to shared memory failure.

 

Has anyone configured Apache with Appian successfully? If yes, then please let provide the steps or any documentation you did to configure. As forum documentation is not helping me to configure it successfully.

 

Thanks in advance.

    Hi,

    I am able to configure Apache with Appian 18.3 recently. I did use the same configuration which I have been using in my Appian-JBoss setup previously (As per the Appian documentation link).

    From the warnings in your setup, it looks like SSL cert issues (mod_ssl) problems. Can you dig into this more.

    Can you check if your issue is same as described in this link.

    Thanks for replying Mangesh.

    I tried to configure by removing all the property for https but it didn't worked with http also so SSL cert only is not only the issue. I will try to configure from previous version documentation and see if it helps.
