Additional Information

The above steps should also apply to CentOS 7.3

The following additional guidance has been provided  by SWAT 
 

1. For the standalone TIM, use at least  tim-rhel7-dist-10.7.0-20180926.070401-2-Linux-el7-x64.zip
2.  Selinux needs to be disabled. Installation will not work through with it.
firewalld needs to be disabled, or rules-set adapted.

Starting Nmap 7.60 ( https://nmap.org ) at 2018-09-26 12:31 CEST
Nmap scan report for 10.10.10.10
Host is up (0.00050s latency).
Not shown: 996 closed ports
PORT    STATE SERVICE
22/tcp  open  ssh
80/tcp  open  http
81/tcp  open  hosts2-ns
443/tcp open  https
MAC Address: 08:00:27:FE:73:A7 (Oracle VirtualBox virtual NIC)
 
PORT   STATE         SERVICE
68/udp open|filtered dhcpc
MAC Address: 08:00:27:FE:73:A7 (Oracle VirtualBox virtual NIC)
These ports are provided on the TIM. By default, only 22 is open. means, no service can be accessed because the local firewall is activated by default. Hence - you h need to open the ports.
 
 

Troubleshooting Information
 - If installation is not successful with the following message: “cannot gracefully restart web server”. Start/Restart and enable httpd service and start installation again.
  • systemctl enable httpd
  • systemctl start httpd
  - If timworker process are not seen in ‘ps -ef | grep tim’  
Possible solutions:
 
  1. Check interface name /opt/CA/APM/tim/config/interfacefilter.xml (default eth0/eth1) and update the name as per ifconfig.
 
<?xml version="1.0" encoding="UTF-8"?>
<!-- This file is generated automatically.Do not edit. -->
<InterfaceFilterFile>

<FileName>Timestock Interface Filter File</FileName>
<FileVersion>1.0</FileVersion>
</File>
<Interfaces>
<Interface>
<Name></Name>
</Interface>
</Interfaces>
</InterfaceFilterFile>

     b. Restart webserver (httpd.service) after installation​
-  If not able to connect to TIM from CEM UI  
  1. Check for firewalld status and disable the firewalld to get access to timconfig file in TIM machine
  2. Check whether TIM is already registered for any other CEM module
