+===== Centos 8 particularities =====
+==== get RPMs ====
+from https://foldingathome.org/start-folding/ get latest RPMs
+<code>
+# wget https://download.foldingathome.org/releases/public/release/fahclient/centos-6.7-64bit/v7.6/fahclient-7.6.9-1.x86_64.rpm
+# wget https://download.foldingathome.org/releases/public/release/fahcontrol/centos-6.7-64bit/v7.6/fahcontrol-7.6.9-1.noarch.rpm
+# wget https://download.foldingathome.org/releases/public/release/fahviewer/centos-6.7-64bit/v7.6/fahviewer-7.6.9-1.x86_64.rpm
+</code>
+As those packages need python2 and python gtk libs and others (freeglut) , we need to install with --nodeps, ref https://foldingathome.org/support/faq/installation-guides/linux/manual-installation-advanced/
+<code>
+#rpm -i --nodeps fahclient-7.6.9-1.x86_64.rpm
+#rpm -i --nodeps fahcontrol-7.6.9-1.noarch.rpm
+#rpm -i --nodeps fahviewer-7.6.9-1.x86_64.rpm
+</code>
+after installation
+<code>
+#  /etc/init.d/FAHClient status
+fahclient is running with PID 25624
+</code>
+===== dependencies =====
+==== pygtk2 ====
+initially FAHControl script fail to start because gtk python module is missing
+<code>
+$ /usr/bin/FAHControl
+Traceback (most recent call last):
+  File "/usr/bin/FAHControl", line 25, in <module>
+    from fah import FAHControl, load_fahcontrol_db
+  File "/usr/lib/python2.7/site-packages/fah/__init__.py", line 25, in <module>
+    import util
+  File "/usr/lib/python2.7/site-packages/fah/util/__init__.py", line 26, in <module>
+    import gtk
+ImportError: No module named gtk
+</code>
+add gtk python module for FAHControl to work
+<code>
+# yum install pygtk2
+</code>
+then FAHControl python script might complain about missing python
+<code>
+$ /usr/bin/FAHControl
+bash: /usr/bin/FAHControl : /usr/bin/python : mauvais interpréteur: Aucun fichier ou dossier de ce type
+</code>
+you can force it to your installed version by editing the 1st line of the script , here /usr/bin/python2.7 (installed aside pyhton3 also on centos 8 )
+<code>
+# head -1 /usr/bin/FAHControl
+#!/usr/bin/python2.7
+</code>
+{{:docpublic:divers:fahcontrol.jpg?300|}}
+config is stored in /etc/fahclient/config.xml
+==== FAHViewer and freeglut ====
+because we installed it with --nodeps !
+<code>
+$ FAHViewer
+FAHViewer: error while loading shared libraries: libglut.so.3: cannot open shared object file: No such file or directory
+</code>
+the add freeglut for FAHviewer
+<code>
+# yum install freeglut
+</code>
