centos7 安装guacamole

Guacamole是一个开源的远程桌面网关，可以让你通过Web浏览器访问远程计算机的桌面环境。下面是在CentOS 7上安装Guacamole的步骤：

1. 更新系统：

   sudo yum update

2. 安装依赖：

   sudo yum install epel-release
   sudo yum install wget
   sudo yum install cairo-devel libjpeg-turbo-devel libpng-devel uuid-devel freerdp-devel pango-devel libssh2-devel libtelnet-devel libvncserver-devel pulseaudio-libs-devel openssl-devel libvorbis-devel libwebp-devel

3. 安装Tomcat：

   sudo yum install tomcat

4. 下载Guacamole：

   wget https://downloads.apache.org/guacamole/1.3.0/source/guacamole-server-1.3.0.tar.gz
   wget https://downloads.apache.org/guacamole/1.3.0/binary/guacamole-1.3.0.war
   wget https://downloads.apache.org/guacamole/1.3.0/binary/guacamole-auth-jdbc-1.3.0.tar.gz

5. 解压并编译Guacamole Server：

   tar -xzf guacamole-server-1.3.0.tar.gz
   cd guacamole-server-1.3.0
   ./configure --with-init-dir=/etc/init.d
   make
   sudo make install
   sudo ldconfig

6. 配置Guacamole Server：

   sudo mkdir /etc/guacamole
   sudo mv guacamole-auth-jdbc-1.3.0.tar.gz /etc/guacamole/
   cd /etc/guacamole
   sudo tar -xzf guacamole-auth-jdbc-1.3.0.tar.gz
   sudo mv guacamole-auth-jdbc-1.3.0/mysql/guacamole-auth-jdbc-mysql-1.3.0.jar /usr/share/tomcat/.guacamole/extensions/

7. 配置MySQL数据库：

   sudo yum install mariadb-server
   sudo systemctl start mariadb
   sudo mysql_secure_installation
   sudo mysql -u root -p
   CREATE DATABASE guacamole_db;
   CREATE USER 'guacamole_user'@'localhost' IDENTIFIED BY 'your_password';
   GRANT SELECT,INSERT,UPDATE,DELETE ON guacamole_db.* TO 'guacamole_user'@'localhost';
   FLUSH PRIVILEGES;
   quit;

8. 配置Guacamole的数据库连接：

   sudo nano /etc/guacamole/guacamole.properties

在文件中添加以下内容：

   mysql-hostname: localhost
   mysql-port: 3306
   mysql-database: guacamole_db
   mysql-username: guacamole_user
   mysql-password: your_password

9. 部署Guacamole Web应用：

   sudo mv guacamole-1.3.0.war /var/lib/tomcat/webapps/guacamole.war
   sudo systemctl restart tomcat

10. 配置防火墙：

    sudo firewall-cmd --zone=public --add-port=8080/tcp --permanent
    sudo firewall-cmd --reload

现在，你可以通过浏览器访问`http://your_server_ip:8080/guacamole`来使用Guacamole了。
