+==== database ====
+afin de permettre a plusieurs utilisateurs de se conencter et enregistrer des preferences il convient de definir une database
+=== arborescence extension ===
+la database ou autre modules d'authentification (ldap, cas ) sont fournit sous forme de module quil faut deployer dans une arborescence specifique que nous créons dans /usr/share/tomcat/.guacamole
+<code>
+[root@rlab etc]# mkdir -p /usr/share/tomcat/.guacamole/{extensions,lib}
+</code>
+=== modules ===
+recuperation et deploiement des modules pour la database
+<code>
+[root@rlab ~]# wget https://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-8.0.20-1.el8.noarch.rpm
+[root@rlab ~]# yum install mysql-connector-java-8.0.20-1.el8.noarch.rpm

+==== mariaDB ====
+apres installation de mariadb-server , on va le securiser
+<code>
+[root@rlab ~]# systemctl start mariadb.service
+[root@rlab ~]# mysql_secure_installation
+Set root password? [Y/n] Y
+New password:
+Re-enter new password: Secret Pa U g... S.. ip5 d Da
+Password updated successfully!
+Reloading privilege tables..
+ ... Success!
+Remove anonymous users? [Y/n] y
+ ... Success!
+Normally, root should only be allowed to connect from 'localhost'.  This
+ensures that someone cannot guess at the root password from the network.
+Disallow root login remotely? [Y/n] y
+ ... Success!
+Remove test database and access to it? [Y/n] y
+ - Dropping test database...
+ ... Success!
+ - Removing privileges on test database...
+ ... Success!
+Reload privilege tables now? [Y/n] y
+Thanks for using MariaDB!

+creation des table et user :

+[root@rlab ~]# cat /root/guacamole-auth-jdbc-1.1.0/mysql/schema/002-create-admin-user.sql | mysql -u root -p guacdb

+=== configuration / properties ===
+<code>
+[root@rlab ~]# mkdir -p /etc/guacamole/ && vi /etc/guacamole/guacamole.properties
+[root@rlab ~]# cat /etc/guacamole/guacamole.properties
+# MySQL properties
+mysql-hostname: localhost
+mysql-port: 3306
+mysql-database: guacdb
+mysql-username: guacuser
+mysql-password: secret
+#Additional settings
+mysql-default-max-connections-per-user: 0
+mysql-default-max-group-connections-per-user: 0
+</code>
+=== permissions ===
+<code>
+[root@rlab ~]# chmod 0400 /etc/guacamole/guacamole.properties
+[root@rlab ~]# chown tomcat:tomcat /etc/guacamole/guacamole.properties
+[root@rlab ~]# ln -s /etc/guacamole/guacamole.properties /usr/share/tomcat/.guacamole/
+[root@rlab ~]# chown tomcat:tomcat /opt/tomcat/webapps/guacamole-1.1.0.war
+</code>
+==== GUACAMOLE_HOME ====
+Tres imprtant pour la configurations des plugins/modules , il faut s'assurer que tomcat charge bien les paremtrages definit dans guacamole.properties. ceci se fait grace à la variable  GUACAMOLE_HOME qui est fixé par defaut a /etc/guacamole/
+comme ci-dessus nus avons definit les propriété dans /usr/share/tomcat/.guacamole/ avec un jeux de liens, et que le homedir du user tomcat dans mon installation est ici dans /opt/tomcat, il convient egalement de créé un lien depuis /opt/tomcat/.guacamole vers  /usr/share/tomcat/.guacamole
+cf https://guacamole.apache.org/doc/gug/configuring-guacamole.html Overriding GUACAMOLE_HOME => Creating a directory named .guacamole, within the home directory of the user running the servlet container. This directory will automatically be used for GUACAMOLE_HOME if it exists.
+<code>
+[root@rlab /opt/tomcat]# ln -s /usr/share/tomcat/.guacamole .guacamole
+</code>
+Apres redemarrage de tomcat , on peut enfin se connecter avec la compte guacadmin (cf fichier d'import sql : 002-create-admin-user.sql) et ainsi changer le password de cet administrateur
