Simple Incoming Webhook – let’s learn how to create a simple incoming webhook that posts the following message to Mattermost

Linux
curl -i -X POST -H ‚Content-Type: application/json‘ -d ‚{„text“: „Hello, World!“}‘ http://<Mattermost Server>:8065/hooks/<generated key>

Windows 10
curl -i -X POST -H „Content-Type: application/json“ -d „{\“text\“: \“Hello, World!\“}“ http://<Mattermost Server>:8065/hooks/<generated key>

A complete Mattermost installation consists of 3 major components: a proxy server, a database server, and the Mattermost server. You can install all components on 1 machine, or you can install each component on its own machine

# apt-get install mariadb-server
# systemctl start mysql

# mysql -p
 MariaDB> create user ‚Mattermost’@’localhost‘ identified by ‚<password>‘;
 MariaDB> create database mattermost;
 MariaDB> grant all privileges on mattermost.* to ‚Mattermost’@’localhost‘;
 MariaDB> exit
