Login into your Centos box with root access

We can just simple answer the installation question until finished.

Starting OpManager

cd /opt/AdventNet/ME/OpManager/bin
./StartOpManagerServer.sh

Problem starting up OpManager 

If you have any problem with WebServer Port is Occupied, then you need to shutdown your old webserver first

/sbin/service httpd stop

and then restart OpManager again. 

If OpManager Failed to Load and the result is Failed to establish connection with web server. Gracefully shutting down OpManager.

You need to make sure all library for apache is available in /usr/lib or /lib
OpManager comes with lib so we can just simply copy the lib to /usr/lib or /lib

cd /opt/AdventNet/ME/OpManager/apache/lib
cp libapr-0.so.0  libaprutil-0.so.0 /usr/lib
cp libapr-0.so.0  libaprutil-0.so.0 /lib

To fix the issue with 'Failed to establish connection. Gracefully shutting...' on a Linux box, please follow the step given below
1. Try starting OpManager server as a "root" user.
2. Create a user and group account "nobody" as in

adduser nobody

groupadd nobody

3. The file libdb-3.2.so may not exist in your system. OpManager bundles this file under lib/backup under OpManager Installation directory.Copy this file to lib directory ie.(Execute this command under /opt/AdventNet/ME/OpManager - this is the default location where OpManager is installed under linux distribution)

cd /opt/AdventNet/ME/OpManager/
cp lib/backup/libdb-3.2.so lib/

If the libdb-4.x.so is the latest version, then you need to create a soft link to it as in

cd /usr/lib
ln -s libdb-4.x.so libdb-3.2.so

(where 'x' refers to the latest libdb version. It can be one among 0,1,2)
4. The file libgdbm.so.2 may not exist in your system. This file is required to start the Apache server. To resolve this, create a soft link for libgdbm-2.so from the latest version of the libgdbm file which will be found under the directory /usr/lib

cd /usr/lib
ln -s libgdbm.so.x libgdbm.so.2

(where 'x' is the latest libgdbm version. It can be one among 3,4,5).

This should fixed the web server problem.

After that try to restart OpManager with StartOpManagerServer.sh again

cd /opt/AdventNet/ME/OpManager/bin
./StartOpManagerServer.sh
