Issue with port 80

Issue : above error showed when used opmn command.

Root Cause: permission issue on apachectl.sh

1.      Solution: Log in as root.

2. Run the following commands in the Oracle home:

3.  cd ORACLE_HOME/ohs/bin

4.  chown root .apachectl

5.  chmod 6750 .apachectl

then run ./opmn startall      (command as oracle fusion installer user like oracle in my case)

case 2:When http server  status is NONE from command  ./opmnctl status then do below solution

1. Allow root to start HTTP Server
1.1Login as root
1.2 Run following command as root
cd ORACLE_HOME/ohs/bin  (Oracle Home in Fusion Middleware 11g is under Middleware Home MW_HOME to know more about ORACLE_HOME, MW_HOME or INSTANCE_HOME in 11g Click here)

chown root .apachectl  (Note* dot infront of apachectl which in Unix means this is hidden file)
chmod 6750 .apachectl

.

2. Change httpd.conf(using user owning OHS – awebtier in my case)
2.1Login as owning OHS 11g
2.2 cd $INSTANCE_HOME/config/OHS/ohs1 (INSTANCE_HOME for OHS by default is $MW_HOME/Oracle_WT1/instances/instance1)
2.3cp httpd.conf httpd.conf_pre_port_80
2.4 Change value against Listen to 80 (by default LISTEN value for OHS is 7777 or 7778 for OHS with webcache)

3.Start OHS using OPMN (using user owning OHS – awebtier in my case)
3.1cd $INSTANCE_HOME/bin (or $MW_HOME/Oracle_WT1/instances/instance1/bin)
3.2./opmnctl startall (stopall and startall if opmn is already running)

4. Test OHS via URL
4.1 Check if port 80 is listening on that machine “netstat -an | grep 80″
4.2 Type URL http://servername:80 (If you don’t specify port with http by default it takes port 80)
