Jitsi Meet RPM packages for RHEL/CentOS/OEL 7
First enable tuxad repository:
rpm -i http://www.tuxad.com/repo/7/tuxad.rpm
We also need the EPEL repository. If you don't have it configured then follow the instructions on fedoraproject.org/wiki/EPEL.
Next required repo is nodesource. Enable it via tuxad meta package:
yum install nodesource-release-el7
Install jitsi-meet-install package which will by dependency also install other required packages:
yum install jitsi-meet-install
Add two entries to your DNS server to point to the server you are installing on:
- jitsi.YOURDOMAIN.COM
- auth.jitsi.YOURDOMAIN.COM
After DNS is set up the final Jitsi Meet configuration can be done. The configuring script will call certbot to get certificates from Let's Encrypt.
It is important that (at least when running the configure script) no service is running on TCP port 80. If you have an http server running on this port then shut it down, run the configure script and then start it up again.
The configure script requires at least the IP address (IPv4) and the hostname. Example:
jitsi-meet-install.sh 1.2.3.4 jitsi.example.com
Run this script with your own settings. You are done!

Power Measuring several SSDs (Crucial, Kingston, Apacer)
I was curious if the widely used Crucial BX 500 did also "fail" as 480 GB model. And actually it shows the same picture as the 240 GB model: Fine consumption on standby, read values "ok" but high on write - with the same high bandwidth from approx. 1 Watts to 3.3 Watts.
Another two Patriot Burst 240 did also show the same results as the first Patriot Burst 240 measurement.
And the Kingston A400 960 was the first "1 TB class" SSD I measured. It did show the same great values like the 480 model did.
In addition to even more SSDs I made also the first measurement of an M.2 SSD (SATA, of course). Values were the same as for 2.5" SSD.

Power Measuring Crucial BX500 240
I ordered a Crucial BX250 because it was several times recommended by german magazine c't (Heise Verlag). It was also part of a recommendation for a DYI low power system "7-Watt-Mini" in c't 24/2019.
Unfortunately I can't understand this recommendation: The SSD has low write transfer rates and has a high power consumption on write. And even its (low) power consumption on read is higher than Corsair, Kingston and Patriot have.

Power Measuring Kingston A400 480 and Samsung MZ7LN128
In this session I measured a Kingston A400 480 which is much better than the smaller sizes. It's as great as the Patriot Burst 480: Very fast and very low power consumption. Additionally an old (used) Samsung 128 was measured.

Finally the third Patriot Burst was tested. The results for the 480 are the same like for the 240: Lowest power consumption and highest speed. Additionally a 2.5 hard disk from WD was tested and two 3.5 disks to see the difference between 2.5 and 3.5.
