This document provides instructions for installing Oracle HTTP Server on Linux. It details downloading and running the Oracle HTTP Server installer, and describes post-installation configuration steps such as setting file permissions to enable listening on port 80. It also provides commands for starting, stopping, and checking the status of Oracle HTTP Server using opmnctl.

20. Post-Install Checks
If you would like to change the port after the installation,
edit$ORACLE_INSTANCE/config/OHS/<component_name>/httpd.conf and change the listen
port. If the listen port is less than 1024, then you need to set uid for root on .apachectl. In Unix,
ports less than 1024 requires root privileges.
If set uid is not set for .apachectl, you would see the following error messages:

So, set the permissions as below:
cd $ORACLE_HOME/Apache/Apache/bin
chown root .apachectl
chmod 6750 .apachectl
[root@oam10 Response]# cd /oracle/middleware/ohs/ohs/bin
[root@oam10 bin]# ls -l .apachectl

Startup and Shutdown
Start or Stop of Oracle HTTP Server is managed by opmnctl. Make sure that environment is
sourced right before calling opmnctl stopall or startall or status.
[oracle@oam10 ~]$ cat ohs.env

ORACLE_INSTANCE=/oracle/middleware/instances/ohs ; export ORACLE_INSTANCE
TNS_ADMIN=$ORACLE_HOME/network/admin ; export TNS_ADMIN
