2 QuantumATK Try it! QuantumATK Contact Docs» License server installation guide - Linux License server installation guide - Linux Version: O PDF document This guide describes how to install and configure a license server on Linux. Tip The license system, Synopsys Common Licensing (SCL) is common to all Synopsys products, and the general documentation can be found here: Synopsys Licensing QuickStart Guide In the present guide, we focus on using the license system for the first time and with only a QuantumATK product. These instructions assume that you are using bash as your shell. If not, you will need to modify the procedure accordingly. Download SCL On Linux, we need to download a total of three files - two for SCL itself, and the Synopsys Installer to perform the actual installation. Point your web browser to If required, enter your Synopsys SolvNet username and password. Click on Downloads in the top bar. Under My Product Releases, choose Synopsys Common Licensing. Choose SCL from the list of available versions. Click Download Here to download SCL by HTTPS. After reading the legal page, click on Yes I agree to the above terms. Click the download buttons next to the files scl_v _common.spf and scl_v _linux64.spf to download them. Follow the browser prompts to select a destination download location. This directory must be a temporary directory and not the target installation directory. Download Synopsys Installer Go back to My Product Releases, and choose Synopsys Installer

3 Choose the latest version from the list of available versions. Click Download Here to download Synopsys Installer by HTTPS. After reading the legal page, click on Yes I agree to the above terms. Click the download button next to the file SynopsysInstaller_v4.2.run to download it. Follow the browser prompts to select a destination download location. This directory must be a temporary directory and not the target installation directory. Install SCL - RHEL and CentOS SCL is designed for use with RHEL, and the installation instructions for these Linux distributions are given below. For instructions on how to install SCL on Ubuntu, skip this section and go here: Install SCL - Debian and Ubuntu Make sure the Synopsys Installer file is executable: chmod 7 SynopsysInstaller_v4.2.run Execute it, to extract the installer to the specified directory:./synopsysinstaller_v4.2.run -d /usr/synopsys/installer Add the Synopsys Installer binaries to your PATH chmod -R 7 /usr/synopsys/installer PATH=/usr/synopsys/installer:$PATH export PATH Make sure the SCL product files ( scl_v _common.spf and scl_v _linux64.spf ) are in a temporary directory. To start the installer, type installer or installer -gui to start the installation. Follow the prompts. The first is the directory where the *.spf files are located. When asked, enter the path to the target directory. You also need to enter your site ID - it can be found in your license key file. You may now proceed to Customizing the License Key File Install SCL - Debian and Ubuntu As SCL is primarily designed for RHEL, the process is a bit more involved for Ubuntu. This guide will therefore be rather brief, and mainly list out the commands with limited commentary. Open a terminal and navigate to the folder where you downloaded the files and execute the following commands: chmod +x SynopsysInstaller_v4.2.run mkdir installer mv SynopsysInstaller_v4.2.run installer/ cd installer./synopsysinstaller_v4.2.run - It should be fine to use the default values, so press enter after reading the text. cd.. mkdir scl You now need to install tcsh: sudo apt-get install tcsh tcsh installer/installer -source. -target scl

4 Press enter and let it run through. Now we need to move the folder up one level. mv scl/scl/* scl/ rm -rf scl/scl We also need to add a link: readelf -a./scl/ /linux64/bin/lmgrd grep "interpreter:" You should get something like this: [Requesting program interpreter: /lib64/ld-lsb-x86-64.so.3] Now take that path and do the following: sudo ln -s /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3 sudo mkdir /usr/tmp Add the following to your.bashrc or equivalent: export PATH="~/scl/ /linux64/bin:$PATH" Customizing the License Key File Before setting up the license server, you need to make a few changes to the license file, to reflect your specific environment. Important You should place the license file in the Synopsys license directory: /usr/synopsys/scl/ /admin/license/ on RHEL/CentOS and ~/scl/ /admin/license/ on Debian/Ubuntu. In the following, we will assume SCL is installed on RHEL/CentOS. If you are using a Debian-type distribution, make sure to change the paths to the appropriate directory. Modify the SERVER line The SERVER line of your key file has the following syntax: SERVER hostname1 hostid tcp_port_number Replace hostname1 with the host name of your machine, which you get from the shell (terminal) command echo $HOSTNAME. The license key file hostid ( 0128D07E321F in the example below) must match your machine host ID. Otherwise the license file will not work. Do not change the hostid in the license file; it will invalidate your license key file. If the hostid is incorrect, contact your account manager to obtain a new license key file. Tip You can change the TCP port number (the Synopsys default is 27020) to any available TCP port between 1024 and (For performance reasons, ports are not recommended for the lmgrd port.)

5 Example SERVER line: SERVER aspen 0128D07E321F Modify the VENDOR line The VENDOR line has the following syntax: VENDOR snpslmd /path/to/snpslmd You should now replace /path/to/snpslmd with the full path to snpslmd on your machine, for example: VENDOR snpslmd /usr/synopsys/scl/ /linux64/bin/snpslmd Optional - Adding a second port If your computer is protected by a port-specific firewall and/or you need to use an ssh tunnel to access the license server, we recommend that you modify the VENDOR line further. You should specify an additional port, under the same constraints as before, at the end of the line: Example VENDOR line: VENDOR snpslmd /usr/synopsys/scl/ /linux64/bin/snpslmd port=28000 You will then need to ensure that your firewall and/or ssh tunnel allows traffic on both of those ports in order to use the license server. If the second port is not specified, it can change from session to session. Note that you do not need to specify this second port when setting up QuantumATK. If you see an error like the one below, specifying the second port should be first thing you try to solve the issue. Cannot connect to license server system. The license server manager (lmgrd) has not been started yet, the wrong port@host or license file is being used, or the port or hostname in the license file has been changed. Feature: atk_nanolab Server name: 1XXXXXXXX1 License path: 27020@hostname; FlexNet Licensing error:-1,10032 Starting the license server To start the license server, type one of the following in a terminal on an unbroken line: RHEL /usr/synopsys/scl/ /linux64/bin/lmgrd -c /usr/synopsys/scl/ /admin/license/synopsyskey.lic -l /usr/synopsys/scl/ /admin/logs/snps.debug.log Ubuntu lmgrd -c ~/scl/ /admin/license/synopsyskey.lic -l ~/scl.log

6 If this is not the first time you start SCL, make sure to shut down snpslmd before proceeding. Verify that the SCL license server has started correctly: Open the log file specified above. Check the time-stamped entries to verify that: lmgrd (FlexNet Licensing) v has started snpslmd (SCL) v has started there are no security errors: Invalid license file fingerprint or WARNING: SSS errors. the list of available (started) keys is correct You can also, at any time, type lmstat -c 27020@localhost in a terminal, where is the port specificed in the SERVER line. This will tell you if your license server is running as expected. When you have verified that the license server is running correctly, you may return to the main installation guide: Downloading, installing and configuring QuantumATK or continue with setting up automatic starting of the license server in the final section. Tip SCL includes these important programs: lmgrd - starts the server lmstat - tells you the status of the server lmdown - kills the server All three of the above-mentioned programs take -c license_file.txt as an argument. They should work without the argument if SNPSLMD_LICENSE_FILE is properly configured. Boot script To avoid starting the license server manually every time you boot the machine, you can use a service file as described below. If you do not wish to this, you may skip this section. The procedure will depend on the OS, so below we have separate instructions for RHEL/CentOS 7, Ubuntu/Debian and RHEL/CentOS 6. Note that the last one differs significantly from the first two. RHEL/CentOS 7 Download the file scl7.service, and customize the paths to make sure they comply with your environment. Put it in the folder /etc/systemd/system/ Make sure it is executable: chmod +x /etc/systemd/system/scl7.service Type sudo systemctl enable scl7 in the terminal. Verify by typing systemctl list-unit-files -t service grep scl7 and checking that it says enabled. Type systemctl start scl7 in the terminal. Ubuntu/Debian Download the file scl.service, and customize the paths to make sure they comply with your environment. Put it in the folder /etc/systemd/system/

7 Type sudo systemctl enable scl in a terminal. Type sudo systemctl start scl in a terminal. Both The license server will now automatically start every time you start your machine, and you should not need to use these commands again. It also accepts the following keywords (replace scl with scl7 for RHEL/CentOS 7): systemctl stop scl will stop the license server. systemctl status scl will print the status of the license server. systemctl reload scl will reload the license file. When stopping the license server, you may see an error like this: username systemd[1]: Stopped Synopsys Common Licensing Server. username systemd[1]: scl.service: Unit entered failed state. username systemd[1]: scl.service: Failed with result 'exit-code'. Ignore it, as the license server should be stopped correctly anyway. RHEL/CentOS 6 Download the file scl6_service, and customize the paths to make sure they comply with your environment. Copy it to /etc/init.d/ Make it executable: chmod +x /etc/init.d/dcl6_service. Configure it: chkconfig --add scl6_service chkconfig scl6_service on chkconfig --list scl6_service Start it by typing service scl6_service start in the terminal. The license server will now automatically start every time you start your machine, and you should not need to use these commands again. You can stop it with service scl6_service stop and disable it with chkconfig scl6_service off. Copyright 2018, QuantumATK Team.
