To move docker files to different folder.

June 8, 2021 by Roger·Comments Off

Product:
Planning Analytics Workspace 63
Red Hat Linux
Issue:
Need more space for the PAW installation. Docker will create is files in /var/ sub-folder.

Use df -h command to check space on your linux server.

Error:
Looks like something went wrong in step “installing/updating IBM planning analytics Docker images”… Check the log file /…..
in images.log : no space left on device

Solution:

Create folders, where you have space, sudo mkdir /data/docker

Stop docker service sudo systemctl stop docker

Update the file /etc/docker/daemon.json with sudo nano daemon.json

{
“graph” : “/data/docker”
}

Save with CTRL+O and exit with CTRL+X.

Start docker with sudo systemctl start docker

To restart the full Linux server enter: sudo reboot

Then run the installation of PAW ./Start.sh script again.

More information:

Storage requirements can vary, you need at least 100 GB for the /var/lib/docker directory and sufficient space for at least two Planning Analytics Workspace installation packages wherever you choose to install them.

How create a certificate request

May 18, 2021 by Roger·Comments Off

Product:
OPENSSL
Linux Centos

Problem:
How create a SSL (TLS) request for a server that need a certificate?

Suggested Solution:

Install openssl on your Centos Linux with command:

yum install openssl

Create a folder to work in mkdir /ibm

Go to that folder cd /ibm

Create a text file with a text editor like; nano san.txt

[ req ]
default_bits       = 2048
distinguished_name = req_distinguished_name
req_extensions     = req_ext
prompt             = no
[ req_distinguished_name ]
countryName                = Country Name (2 letter code)
stateOrProvinceName        = State or Province Name (full name)
localityName               = Locality Name (eg, city)
organizationName           = Organization Name (eg, company)
commonName                 = Common Name (e.g. server FQDN or YOUR name)
[ req_ext ]
subjectAltName = @alt_names
[alt_names]
DNS.1   = servername
DNS.2   = servername.domain.com
DNS.3   = dnsalias.domain.com

Save above text in the file after you change to your server-names.
openssl req -out /ibm/request.csr -newkey rsa:2048 -nodes -keyout /ibm/privateKey.pem -config /ibm/san.txt
Above will give a new server private key and a certificate request for a cert.

Check the request with command:

openssl req -text -noout -verify -in request.csr

Check the private key with command:

openssl rsa -in privateKey.pem -check

The private-key should only be stored on the server where it should be used.
The certificate request you copy and paste to your Certificate Authority to generate your certificate.

SSL Experten

newkey rsa:2048

This option creates a new certificate request and a new private key.

Product:
IBM License Metric Tool on Linux
Red Hat Enterprise Linux 7.5 or a higher 7.x version
Issue:
How install ILMT on Linux in one step

https://www.ibm.com/docs/en/license-metric-tool?topic=il-step-by-step-installation-guide-all-in-one-installer
Suggested Solution:
You need to install on Red Hat Enterprise Linux 7.5 or a higher 7.x version, but for this test we will use CentOS Linux https://www.centos.org/download/
Install CentOS with a fix IP address, so you can easy connect to the Linux server.

Download the installation file “ILMT_Install_Lnx-x86-64_V9222.tar.gz”

https://www.ibm.com/support/pages/node/582891#linux

Copy the file to your linux server with WinSCP program. https://winscp.net/eng/download.php

Check disk space with command df -h

https://www.ibm.com/docs/en/license-metric-tool?topic=requirements-hardware-server-linux

Install the needed programs https://www.ibm.com/docs/en/license-metric-tool?topic=requirements-software

yum install byobu

yum install libnsl

yum install libstdc++

yum install ksh

yum install pam*i686

yum install numactl*x86_64

yum install libstdc++*i686

yum install libpng12.x86_64

yum install fontconfig.x86_64

yum install libXext.x86_64

yum install libXrender.x86_64

yum install unixODBC.x86_64

yum install nano

yum install wget*x86_64

Unzip the tar file with command: tar zxvf ILMT_Install_Lnx-x86-64_V9222.tar.gz

Copy the install_response.txt to a new file with command: cp install_response.txt response.txt
Edit that file in nano response.txt

Change the following values;

RSP_LICENSE_ACCEPTED=true

RSP_ADMIN_PASSWORD=

RSP_DB2_INST_PASSWORD=

#RSP_DB2_ROOT=/opt/ibm/db2/V11.5 (if you want DB2 installed in a different folder)

RSP_IEM_TEM_USER_PASSWORD=

#RSP_IEM_WR_WWW_PORT=8083 (if you want to change the port number used by BigFix)

#RSP_TLM_ROOT=/opt/ibm/LMT (if you want ILMT installed to other folder)

#RSP_TLM_HTTPS_PORT=9081 (if you want to change The port for administration server web UI)

Save the file, and run below command to start the installation:

./setup-server-linux-x86_64.sh -i silent -f /ibm/response.txt

You must install to Red Hat. For this test we enter export disable_platform_check=true

Then the check in the script file will skip the check (if [ “$disable_platform_check” != “true” ]
then)….

Go to /root folder and enter command to unzip the log files:

tar zxvf LMT_9.2.22.0_20210514-113503_16243_logs.tar.gz

Check the log file with commando:

tail LMT_9.2.22.0_20210514-113503_16243_logs/LMT9.2.22.0/Server.log

Solve the issue and run the ./setup-server-linux-x86_64.sh -i silent -f /ibm/response.txt again.

Add the BigFix port and ILMT port to the firewall on Linux server with commands:

firewall-cmd --permanent --add-port=52311/tcp

firewall-cmd --permanent --add-port=9081/tcp

firewall-cmd --reload

Copy windows client files to your windows share for clients with winSCP

Create a CMD file with this text to run the installation locally on the windows clients:

BigFix-BES-Client-10.0.2.52.exe /s /v”/L*vx! \”C:\temp\ClientInstallLog.txt\” SETUPEXE=1 REBOOT=ReallySuppress MSIRESTARTMANAGERCONTROL=Disable /qn”

Check the client windows services for “BES Client”, to see that it was installed.

Copy BIGFIX console files to your windows computer with winSCP

The files are in folder /var/opt/BESInstallers/ directory.

Run the BigFix console setup on a computer, and ensure the clients are listed in the Go to Sites – External Sites – IBM License Reporting (ILMT) – Fixlets and tasks – Install or Upgrade Scanner, task.

Browse to https://yourservername:9081/ in Chrome.

First time you log into ILMT webpage you should get above dialog, to import the data from BigFix server.

Install BigFix Client on Centos

April 22, 2021 by Roger·Comments Off

Product:
BigFix Client
Problem:
How install BES client on centos machine?

Solution:

Copy the client and masthead files to the Centos computer.

The file you need for masthead is found in folder /var/opt/BESInstallers/Client on server where ILMT is installed.

On the target computer create the folder: mkdir /etc/opt/BESClient/

Copy the file to the target with scp command, you need to connect with a user that have access to the folders

scp root@centos74:/var/opt/BESInstallers/Client/actionsite.afxm actionsite.afxm

Copy the client with command: scp root@centos74:/var/opt/BESInstallers/Client/BESAgent-10.0.2.52-rhe6.x86_64.rpm BESAgent-10.0.2.52-rhe6.x86_64.rpm

You can also download the BES Client/Agent from https://support.bigfix.com/bes/release/10.0/patch2/

Install the client rpm -ivh BESAgent-10.0.2.52-rhe6.x86_64.rpm

Start the client with command

/etc/init.d/besclient start

You can check if the BIGFIX (BES Client) is running with TOP command.

How manage the ILMT?

Setup the BigFix console on a windows computer to be able to manage the system.

Copy the console folder to your windows host with WinSCP, from /var/opt/BESInstallers/Console

Run the setup.exe to install the console on your windows computer

If you get timeout errors, check that the firewalls allow port 52311 that is used by BigFix.

firewall-cmd --permanent --add-port=52311/tcp

firewall-cmd --reload

If all software components are installed and configured on the server, this are the steps to activate the scan from BigFix console.

Start the BigFix console “C:\Program Files (x86)\BigFix Enterprise\BES Console\BESConsole.exe”
