1.创建一个临时文件夹，用来存放mysql-java连接器
mkdir tempauth
2.下载相关文件
cd tempauth
wget https://jaist.dl.sourceforge.net/project/guacamole/current/extensions/guacamole-auth-jdbc-0.9.14.tar.gz
wget https://cdn.mysql.com//Downloads/Connector-J/mysql-connector-java-5.1.46.tar.gz
点击这里下载 要注意这个版本只适用于0.9.14的guacamole-server
3.安装/解压
tar -zxf mysql-connector-java-5.1.46.tar.gz
tar -zxf guacamole-auth-jdbc-0.9.14.tar.gz
4.将guacamole-auth复制到GUACAMOLE_HOME的extensions文件下，若无则创建.GUACAMOLE_HOME一般为/etc/guacamole/
cp /etc/guacamole/tmpauth/guacamole-auth-jdbc-0.9.14/mysql/guacamole-auth-jdbc-mysql-0.9.14.jar /etc/guacamole/extensions/
cp /etc/guacamole/tmpauth/mysql-connector-java-5.1.46/mysql-connector-java-5.1.46-bin.jar /etc/guacamole/lib/
5.创建Guacamole数据库
$ mysql -u root -p
Enter password: password

Bye
6.进入到/etc/guacamole/sqlauth/guacamole-auth-jdbc-0.9.14/mysql/schema下，执行sql脚本
root@ubuntu:/etc/guacamole/sqlauth/guacamole-auth-jdbc-0.9.14/mysql/schema# ls
001-create-schema.sql 002-create-admin-user.sql upgrade
root@ubuntu:/etc/guacamole/sqlauth/guacamole-auth-jdbc-0.9.14/mysql/schema# cat ./*.sql | mysql -u root -p guacamole_db
Enter password:
root@ubuntu:/etc/guacamole/sqlauth/guacamole-auth-jdbc-0.9.14/mysql/schema#
7.配置guacamole.properites相关信息
# MySQL properties
mysql-hostname: localhost
mysql-port: 3306
mysql-database: guacamole_db
mysql-username: guacamole_user
mysql-password: some_password
注意，如果没有配置数据库信息，使用user-mapping.xml 没有类似历史访问记录，sftp等功能
注意 guacamole-auth-jdbc 一定要和guancd 的版本号对应，否则会出现登陆失败的情况
可以按照下面的方法查看版本号：
root@ubuntu:/etc/guacamole# /etc/init.d/guacd restart
Stopping guacd: SUCCESS
Starting guacd: guacd[4497]: INFO: Guacamole proxy daemon (guacd) version 0.9.13-incubating started
SUCCESS
#
这里显示的版本号为 0.9.23-incubating 下载时一定要注意下载对应版本
日志记录在/var/log/tomcat8下面 注意为catalina.out文件，有问题及时查看方便解决
