basic dockerized jitsi deployment with an apache reverse proxy on centos

After a friend of mine told me he wanted to deploy Jitsi on my main webserver, and me saying “sure”, I decided I wanted to get it up and running on a new server both so I knew how to do it, and to avoid the latency issues of videoconferencing from central North America to Germany and back.

Before I go into how I got it working, let me say that the official Quick Start guide is good – but it doesn’t cover anything but itself.

Here’s the basic setup:

CentOS 7
Docker
Apache 2.4

What To Do:

Once you have your new CentOS instance up and running (I used Vultr), here’s everything you need to install:

yum -y install epel-release && yum -y upgrade && yum -y install httpd docker docker-compose screen bind-utils certbot git haveged net-tools mod_ssl

I also installed a few other things, but that’s because I’m multi-purposing this server for Squid, and other things, too.

Enable Apache, firewalld, & Docker:

systemctl enable httpd && systemctl enable docker && systemctl enable firewalld

Now get your swap space setup:

fallocate -l 4G /swapfile && chmod 0600 /swapfile && mkswap /swapfil && swapon /swapfile

Add the following line to the bottom of your /etc/fstab:

/swapfile swap swap default 0 0

Restart your VPS:

shutdown -r now

Get your cert from Let’s Encrypt (make sure you’ve already setup appropriate CAA & A records for your domain and any subdomains you want to use):

certbot -t -n --agree-tos --keep --expand --standalone certonly --must-staple --rsa-key-size 4096 --preferred-challenges dns-01,http-01 -m <user>@<domain.tld> -d <jitsi.yourdomain.tld>

Create a root crontab entry to run certbot frequently (I do @weekly ~/renew-le.sh)

Go to the home directory of whatever user you plan to run Jitsi as:

su - <jitsi-user>

Begin the Quick Start directions:

git clone https://github.com/jitsi/docker-jitsi-meet && cd docker-jitsi-meet
mv env.example .env
Change the timezone in .env from Europe/Amsterdam if you want it to show up in a sane timezone (like Etc/UTC)
mkdir -p ~/.jitsi-meet-cfg/{web/letsencrypt,transcripts,prosody,jicofo,jvb}
docker-compose up -d

Now configure Apache for SSL. Start with this reference I posted.

But in the [sub]domain-specific conf file z-[sub]domain-tld.conf, add proxy and authentication lines (so that only people you allow to use your video conference can actually use it):

ProxyPreserveHost on
ProxyPass / http://localhost:8000/ nocanon
ProxyPassReverse / http://localhost:8000/
ProxyRequests       off
ServerAdmin warren@warrenmyers.com
AllowEncodedSlashes NoDecode
<Proxy http://localhost:8000/*>
    Order deny,allow
    Allow from all
    Authtype Basic
    Authname "Password Required"
    AuthUserFile /etc/httpd/.htpasswd
    Require valid-user
</Proxy>
RewriteEngine       on
RewriteRule        ^/meetwith/(.*)$ http://%{HTTP_HOST}/$1 [P]
ProxyPassReverseCookiePath /meetwith /

Reload your configs, and make sure they’re happy, fixing any errors that may exist:

apachectl graceful

Setup at least one user who’ll be able to access the site:

htpasswd -B -c /etc/httpd/.htpasswd <user>

You should also configure firewalld to allow only what you want (http, https, ssh):

firewall-cmd --zone=public --add-service=http && firewall-cmd --zone=public --add-service=https && firewall-cmd --zone=public --add-service=ssh

With any luck, when you now navigate to https://[sub.]domain.tld in your web browser, and enter your username and password you created with htpasswd, you’ll get the Jitsi welcome page!
