Install Data Collector software on Linux

To install Data Collector software on Linux:

Login as root on the server where IT Analytics Data Collector has to be installed.
If the Data Collector system is having low entropy, it can affect the performance of cryptographic functions and such steps can take considerable amount of time to complete. You can identify the entropy level of the system from the content of the /proc/sys/kernel/random/entropy_avail file using command # cat /proc/sys/kernel/random/entropy_avail. If this value is not more than 400 consistently, install the rng-tools and start the services as described below on the data collector system.
Install the rng-tools and start the services as described below.
For RHEL or OEL:
- Access the command prompt.
- Install the rng-tools.
```
yum install rng-tools
```
- Start the services.
```
systemctl start rngd 
```
- Enable the services.
```
systemctl start rngd 
```
For SUSE:
- Access the command prompt.
- Install the rng-tools.
```
zypper install rng-tools
```
- Start the services.
```
systemctl start rng-tools
```
- Enable the services.
```
systemctl enable rng-tools
```
Ensure the following rpms are present on the system:
On SUSE: libXrender1 and libXtst6 insserv-compat
On other Linux systems: libXtst and libXrender chkconfig
Since the above rpms are essential for proper functioning of the Data Collector, you can run the below commands on the Data Collector server to check whether the rpms are present.
On SUSE: rpm -q libXrender1 libXtst6 insserv-compat
On other Linux systems: rpm -q libXtst libXrender chkconfig
The output of the above commands will print the rpms that are present on the system.
Go to the downloads section under Support on www.veritas.com and click the relevant download link.
Mount the ISO image that you downloaded.

```
cd /
/mnt/diska/dc_installer.sh
```
Review the End User License Agreement (EULA) and enter accept to agree.
Provide the install location. The default location is /usr/openv/analyticscollector. Accepting the default paths is recommended.
If you specify a custom location, analyticscollector directory is created at the specified location.
The installer requests for the following details.
- Data Collector Registration File Path: Enter the absolute file path of the registration file generated and downloaded from the IT Analytics Portal.
- Web Proxy (HTTP) settings can be configured. Enter y to configure proxy. The installer prompts for:
  - HTTP Proxy IP Address: Enter the hostname or IP address and a port number.
  - HTTP Proxy Port: Enter the proxy port number for HTTP proxy.
  - Proxy UserId and password: Enter the credentials for the proxy server.
  - No Proxy For: Enter the host names or IP addresses separated by commas that will not be routed through the proxy.

The Data Collector installation is complete. You can run the <Data_Collector_Install_Location>/analyticscollector/mbs/bin/checkinstall.sh file for verification.
