安裝jitsi的流程記錄一下 ubuntu 20.04

os安裝好後

apt update

apt upgrade -y

在DNS上設定好server的name

接下來 

apt install curl gnupg

curl https://download.jitsi.org/jitsi-key.gpg.key | sudo sh -c 'gpg --dearmor > /usr/share/keyrings/jitsi-keyring.gpg'

echo 'deb [signed-by=/usr/share/keyrings/jitsi-keyring.gpg] https://download.jitsi.org stable/' | sudo tee /etc/apt/sources.list.d/jitsi-stable.list > /dev/null

sudo apt-get -y update

sudo apt-get -y install jitsi-meet

如果要使用letsencrypt

apt install certbot

/usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh

重啟nginx

到 https://servername

就可以使用了

letsencrypt要記得每三個月renew一次

或使用crontab 

1 1 * * 6 /usr/bin/certbot renew

昨天收到來自 Let's Encrypt 的 mail

Hello,

**Action is required to prevent your Let's Encrypt certificate renewals from breaking.**

Your Let’s Encrypt client used ACME TLS-SNI-01 domain validation to issue a certificate in the past 60 days.

TLS-SNI-01 validation is reaching end-of-life and will stop working on **February 13th, 2019.**

You need to update your ACME client to use an alternative validation method (HTTP-01, DNS-01 or TLS-ALPN-01) before this date or your certificate renewals will break and existing certificates will start to expire.

我是使用certbot來更新

原來的指令是

/usr/bin/certbot renew

預設就是使用 TLS-SNI-01

所以要把指令改成

/usr/bin/certbot --preferred-challenges http-01 renew
