SOLVED: Installing Tango on Rocky Linux 8 or 9

# 1 year ago
curb4n	Hi, does anyone have tried to install Tango on a Red Hat compatible Linux distro like Rocky Linux? I'm trying the installation with the help of a custom Ansible playbook, but at the end in both Rocky 8 and 9, the starter daemon segfaults with the following error (on a Rocky Linux 8): `omniORB: (0) 2023-08-28 13:54:36.494685: Application check failed. This indicates a bug in the application using omniORB. See the comment in the source code for more info. file: ../../../../../src/lib/omniORB/orbcore/corbaOrb.cc line: 670 info: pd_destroyed` The databaseds seems to run correctly. Some details on libraries installed: - mariadb 10.3 (on Rocky 8), 10.5 (on Rocky 9) - omniORB 4.2.2 - zmq 4.3.4 - Tango 9.3.5 (on Rocky 8), 9.3.6 (on Rocky 9) Thank you! Best regards, Cristiano Urban.

Hi,

I'm trying the installation with the help of a custom Ansible playbook, but at the end in both Rocky 8 and 9, the starter daemon segfaults with the following error (on a Rocky Linux 8):


omniORB: (0) 2023-08-28 13:54:36.494685: Application check failed. This indicates a bug in the application using omniORB.  See the comment in the source code for more info.

The databaseds seems to run correctly.

Some details on libraries installed:
- mariadb 10.3 (on Rocky 8), 10.5 (on Rocky 9)
- omniORB 4.2.2
- zmq 4.3.4
- Tango 9.3.5 (on Rocky 8), 9.3.6 (on Rocky 9)

Thank you!

Best regards,

Reynald	Hi Cristiano, What version of the Starter Device Server are you using? Could this be related to the following issue which has been solved recently? –> https://gitlab.com/tango-controls/starter/-/issues/24 Could you try to compile the Starter from the Starter main branch and check whether the problem is still there on the Starter git repository main branch? Thanks for your feedback! Kind regards, Reynald Rosenberg's Law: Software is easy to make, except when you want it to do something new. Corollary: The only software that's worth making is software that does something new.

Reynald	Reynald Could you try to compile the Starter from the Starter main branch and check whether the problem is still there on the Starter git repository main branch? Ooops, I meant 9.3-backports branch, not the main branch, since you are using cpptango 9.3.x Sorry for the confusion.

curb4n	Hi Reynald, thank you for your answer, I've made some tests and I report some details here below. All the tests have been made on Rocky Linux 8 with the very same configuration of the initial post, except for the version of Tango: this time I used the v9.3.6. In the next period I think I will do more detailed tests also on Rocky Linux 9. The Starter version should be v7.6 according to the CHANGELOG in the cppserver folder. Anyway, I tried to compile and run the Starter separately, as you advised me: `git clone –branch 9.3-backports https://gitlab.com/tango-controls/starter.git cd starter mkdir build && cd build cmake ../ make ./Starter <my_hostname> The device server Starter/<my_hostname> is not defined in database. Exiting! host=$(hostname -s) && tango_admin –add-server Starter/$host Starter tango/admin/$host ./Starter <my_hostname> ENOENT 2 No such file or directory` So, in this case, it seems to run without crashing. —– I've also tried to apply the patch you linked me. `cd /home/controls/download/tango-9.3.6/cppserver/starter wget https://gitlab.com/tango-controls/starter/uploads/0f3dff7011ae8114b2aad9a1c9487224/0001-Starter.cpp-Fix-indexing-error.patch patch -i 0001-Starter.cpp-Fix-indexing-error.patch patching file Starter.cpp` Then I've compiled Tango again, after having uninstalled the previous installation. Here below, the configure: `Configuration (tango): Source code location: .. Version: 9.3.6 Compiler: gcc,g++ OMNIORB PATH: /usr/local/omniORB-4.2.2 OMNIORB VERSION: "4.2.2" ZMQ PATH: /usr ZMQ VERSION: 4.3.4 JAVA PATH: /usr/bin/java JAVA VERSION: 1.8.0_382 Database MARIADB CLIENT LIB: -lmariadb CLIENT VERSION: 3.1.11 VERSION: 10.3.35-MariaDB CONNECTION: OK build: libraries: yes java application: yes access control server: yes database server: yes database schema create: yes` Unfortunately, this patch does not seem to solve the issue. I attached to this post my ansible scripts, if that helps in some way. Cristiano. Attachments: 7Kb

Hi Reynald,
thank you for your answer, I've made some tests and I report some details here below.

All the tests have been made on Rocky Linux 8 with the very same configuration of the initial post, except for the version of Tango: this time I used the v9.3.6.

In the next period I think I will do more detailed tests also on Rocky Linux 9.

The Starter version should be v7.6 according to the CHANGELOG in the cppserver folder.

Anyway, I tried to compile and run the Starter separately, as you advised me:

git clone –branch 9.3-backports https://gitlab.com/tango-controls/starter.git
cd starter
mkdir build && cd build
cmake ../
make
./Starter <my_hostname>
The device server Starter/<my_hostname> is not defined in database. Exiting!
host=$(hostname -s) && tango_admin –add-server Starter/$host Starter tango/admin/$host
./Starter <my_hostname>
ENOENT
2  No such file or directory

So, in this case, it seems to run without crashing.

I've also tried to apply the patch you linked me.

cd /home/controls/download/tango-9.3.6/cppserver/starter
wget https://gitlab.com/tango-controls/starter/uploads/0f3dff7011ae8114b2aad9a1c9487224/0001-Starter.cpp-Fix-indexing-error.patch
patch -i 0001-Starter.cpp-Fix-indexing-error.patch
patching file Starter.cpp

Then I've compiled Tango again, after having uninstalled the previous installation.

Here below, the configure:

Configuration (tango):

        Source code location:       ..

Unfortunately, this patch does not seem to solve the issue.

I attached to this post my ansible scripts, if that helps in some way.

curb4n	Hi, ok, I think I figured out what the problem was: environment variables of the systemd units were not read correctly from config files. I've attached here below a new version of my ansible scripts, just to make it available. I tested them only on Rocky 8 for now. I think we can mark this thread as SOLVED. Thank you! Cheers, Cristiano. Attachments: 6Kb

benjaminbertrand	Hi! I only saw this thread now. I just wanted to mention that we maintain some Tango RPMs. See https://gitlab.com/tango-controls/RPM/tango-spec You can install them from Copr @tango-controls/tango or from MAX IV public repo. They are available for Rocky 8. We haven't built them for Rocky 9 yet.
