Vagrant config for SAP NW752 SP01 dev edition

Version: 1.2.1

What is it ?

This repo contains a Vagrant script and set of deployment scripts which installs SAP NW752 SP01 dev edition in Ubuntu in Virtual Box environment with minimal manual steps required. The target is that you copy the script, download distribs, run Vagrant which will do allmost of steps from the offical guide and some more, and then you have ready system which just needs the post install license steps. In addition to the official installation guide the script does:

• configures NW to autostart on virtual machine startup
• can optionally install github and gitlab SSL certificates to use with abapGit
• can optionally install latest abapGit

How to install

• install virtual box
• install vagrant. Note: vagrant may require Powershell 3 on Window 7. If this is an issue check this.
• download this repository (as zip or git clone)
• put uncompressed distribution files into distrib subfolder of the cloned dir
• open shell in cloned directory (where Vagrantfile is)
• run vagrant up
• wait for installation to finish ... (took ~1-1.5 hours on my laptop)
• you can connect to the system and follow the post-install steps from the official guide (in particular SAP licence installation). The system will be at 127.0.0.1, 00, NPL
• optionally, run vagrant ssh -c "sudo /vagrant/scripts/install_addons.sh" to install SSL certificates mentioned above and latest abapGit. This can only be done AFTER licence installation.

Additional features

• specify --vm-name parameter to set virtual machine name explicitly instead of defaults. E.g. to create several instances. Make sure to specify the option before the vagrant command (e.g. up or destroy).

vagrant --vm-name=HelloWorld up 

How to use

Starting from v1.1 of this repo the scripts install sapnw as a systemd service and enables it by default. So the netveawer should automatically start on boot (note that it will take a minute or two after the machine is up) and you should be able to connect. On the system halt the service will attempt to gracefully stop NW (with 5 min timeout). If you want to disable the service for whatever reason run vagrant ssh -c "sudo systemctl disable sapnw", then start/stop sap manually (see below).

Start/stop virtual machine

• all the below assumes you started the console in the Vagrantfile directory
• whenever you want to start NW
  • start vm with vagrant up
• to stop instance
  • run vagrant halt
• to go inside linux
  • run vagrant ssh
• completely remove virtual machine destroying all data
  • run vagrant destroy

Alternatively you can run VM directly from virtual box, Vagrant did it's job by now and now it is just a convenient option.

Useful commands for systemd service control

• the following commands can be issued either with vagrant ssh -c "<command>" or when logged in the system with vagrant ssh
• check service status
  • sudo systemctl status sapnw
• starting/stopping
  • sudo systemctl start sapnw - manually start the service
  • sudo systemctl stop sapnw - manually stop the service
  • sudo systemctl enable sapnw - enable service autostart
  • sudo systemctl disable sapnw - disable service autostart
  • sudo systemctl daemon-reload - reload service script in case you changed it manually (/etc/systemd/system/sapnw.service)
• see the journal (start/stop output)
  • sudo journalctl -u sapnw -b
  • sudo journalctl -u sapnw -f - output last message and follow new ones (useful after manual sudo systemctl start sapnw)
  • sudo cat /var/log/syslog | grep sapnw - same but from system log (may have more info)
  • sudo cat /var/log/syslog | grep SAPNPL - to see sap instance messages
• useful links about systemd services digitalocean systemd guide, systemd wiki, freedesktop systemd docs

Manual mode (if the service is disabled)

• assuming you started the console in the Vagrantfile directory and started the vm ...
• vagrant ssh -c startsap.sh - start sap system
• vagrant ssh -c stopsap.sh - stop sap system

Additional comments

• you may start the vm from any directory but then you need to address it by id or name. Run vagrant global-status to check the name. It should be sapnw. So the command to vm would look like vagrant up sapnw or vagrant ssh sapnw -c <command>
• startsap.sh and stopsap.sh are shortcuts that are placed to /usr/local/bin during installation. They contain command like sudo -i -u npladm startsap.

Infos

What is vagrant

A tool to setup virtual environments conveniently. No need to go through boring installation process which is a plus. Basic virtual machine is created within seconds (for popular flavors that exist in vagrant cloud repository).

Why not docker? (my opinion, no offends :)

1. Imho docker is supposed to be stateless. Databases should be in volumes, not inside docker layer.
2. Besides, docker storage layer is slower than volumes (AFAIK)

P.S.: Probably this can be solved. /sybase directory can be mounted to volume. Also logs and transports should be considered. Well, I don't have enough basis skills for this :) Maybe someday.
P.P.S.: Docker has a lot of potential in terms of composability. E.g. compose several pods with NW dev edition, HANA express for sidecar, configured SMTP server and make them interact. Feel free to reuse the scripts from the repo, they should be very portable to docker, in fact they work inside Ubuntu so might be zero changes needed.

Why Ubuntu

1. Ubuntu is very popular linux flavor. The community is huge and there are a lot of materials on how to solve this or that issue
2. Bare ubuntu server is just ~1 GB in size
3. and yes, I know debian-like system better than other flavors ;) might be the main reason.

Memory

Currently machine is setup to consume 6GB. Though in my experiance 4GB is usually enough (ungrounded opinion). One option to decrease memory usage is to activate swap. To do this:

• uncomment vb.memory = "4096" in Vagrantfile (and comment the one with 6GB)
• uncomment config.vm.provision "shell", path: "scripts/add_swap.sh" - this will activate swap during installation. Or just run it after install via ssh /vagrant/scripts/add_swap.sh

SSL certificates

SSL certificatesinstallation can be triggered by /vagrant/scripts/install_addons.sh or separate /vagrant/scripts/addons/install_ssl_certificates.sh scripts. It install the files from certificates directory. The repositiry contains certificates of github and gitlab. However, you can add more (in *.cer format) before running the script above. The script will install all the certificates that are in the folder. In order to initiate certificate script again later (if you don't want to install certificates manually via STRUST), login to ssh and run /vagrant/scripts/addons/install_ssl_certificates.sh.
