关于搭建guacamole-server.1.4.0简单步骤，及问题记录

问题1： 在guacamole-server.1.4.0目录下，执行./configure,发现记录中出现以下警告，并且VNC没有成功加载（libvncserver.devel已经导入yum的情况下）

libvncserver appears to be built against
   libgcrypt, but the libgcrypt headers
   could not be found. VNC will be disabled.

解决： 需要加载 libgcrypt： 执行yum -y install crypt*(一般执行这一步就可以了)；yum install libgcrypt*（可以不支执行）

简单安装步骤：

1、下载guacamole相关资源包：Apache Guacamole™: 1.4.0

2、guacamole相关依赖参考官网-Installing Guacamole natively — Apache Guacamole Manual v1.4.0

预备安装

yum install gcc

基础依赖

 yum -y install cairo-devel libjpeg-turbo-devel libpng-devel uuid-devel

扩展依赖，如VNC、RDP、SSH协议等等

 yum -y install ffmpeg-devel（如果导入失败，则执行以下操作，安装ffmpeg时间有点长）

安装ffmpeg时需要提前安装yasm插件。下面开始安装

# wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
# tar -xvf yasm-1.3.0.tar.gz
# cd yasm-1.3.0/
# ./configure && make && make install

添加可选依赖

yum -y install cairo-devel libjpeg-turbo-devel libpng-devel uuid-devel
yum -y install freerdp-devel pango-devel
yum -y install libssh2-devel libtelnet-devel libvncserver-devel libwebsockets-devel
yum -y install pulseaudio-libs-devel openssl-devel
yum -y install libvorbis-devel libwebp-devel

开始安装ffmpeg，时间有点长

# wget http://ffmpeg.org/releases/ffmpeg-4.2.2.tar.gz
# tar -xvf ffmpeg-4.2.2.tar.gz
# cd ffmpeg-4.2.2/
# ./configure && make && make install 

解压之前下载好的服务端包：guacamole-server-1.4.0.tar.gz
tar -zxvf guacamole-server-1.4.0.tar.gz
cd guacamole-server-1.4.0

预编译，并检查添加依赖是否生效
./configure --with-init-dir=/etc/init.d
make && make install
ldconfig

因为我这边只需要安装服务端，只需要在/etc/guacamole目录下新增配置文件guacd.conf：

[daemon]
pid_file = /var/run/guacd.pid
log_level = info

[server]
bind_host = 0.0.0.0
bind_port = 4822

[ssl]
server_certificate = /etc/ssl/certs/guacd.crt
server_key = /etc/ssl/private/guacd.key
 

简单写springboot 集成自定义guacamole客户端，为了方便使用我采用集成GuacamoleWebSocketTunnelEndpoint

 @Override
    public GuacamoleTunnel createTunnel(Session session, EndpointConfig endpointConfig) throws GuacamoleException {
        System.out.println("createTunnel WebSocket start");
        String guacaMoleHostName = "127.0.0.1"
        int guacaMolePort = 4822;
      
        // 获取前端参数
        Map<String, List<String>> requestMap = session.getRequestParameterMap();
        Integer height = Integer.valueOf(getMapByKey(requestMap, "height"));
        Integer width = Integer.valueOf(getMapByKey(requestMap, "width"));
        GuacamoleClientInformation information = new GuacamoleClientInformation();
//        information.setOptimalScreenHeight(height);
//        information.setOptimalScreenWidth(width);
        // 获取远程服务器相关信息
        String protocol = getMapByKey(requestMap, "protocol");
        String port = getMapByKey(requestMap, "port");
        String hostName = getMapByKey(requestMap, "hostName");
        String userName = getMapByKey(requestMap, "userName");
        String password = getMapByKey(requestMap, "password");

        String dataTime = DateUtils.getNowTime(SysConstant.DATE_LONG_PATTERN);

        // 通过自定义SpringContextUtils获取springboot容器内的bean
      
        ComServerServiceImpl comServerService = SpringContextUtils.getBean(ComServerServiceImpl.class);
        
        
        GuacamoleConfiguration configuration = new GuacamoleConfiguration();
        // 注意：后台不要自定义configuration.setConnectionID, 否则前端无法连接tunnel
        configuration.setProtocol(protocol);
        configuration.setParameter("hostname", hostName);
        configuration.setParameter("port", port);
        configuration.setParameter("username", userName);
        configuration.setParameter("password", password);
        configuration.setParameter("ignore-cert", "true");

//        String fileName = DateUtils.getNowTime() + ".guac";//文件名
//        String outputFilePath = "/home/guacamole";
//        //添加会话录制--录屏
//        configuration.setParameter("recording-path", outputFilePath);
//        configuration.setParameter("create-recording-path", "true");
//        configuration.setParameter("recording-name", fileName);

        GuacamoleSocket socket = new ConfiguredGuacamoleSocket(
                new InetGuacamoleSocket(guacaMoleHostName, guacaMolePort),
                configuration,
                information
        );

        GuacamoleTunnel tunnel = new SimpleGuacamoleTunnel(socket);
        System.out.println("createTunnel WebSocket success");
        return tunnel;
    }

前端html测试代码

            var encodePara = "34d8b7e8c4145911969f9246688ad39c4a";
            var param = "sid="+sid+"&height=768&width=1024&protocol=rdp&port=3389&hostName=116.196.106.221&userName=administrator&password="+encodePara;
             
            var guac = new Guacamole.Client(
                //new Guacamole.HTTPTunnel("/guacamole/tunnel")
                // websoket "&"：表示结束，注意特殊字符encodeURIComponent(val)编码
                new Guacamole.WebSocketTunnel("/webSocket?"+ param +"&")
             );

            // Add client to display div
            display.appendChild(guac.getDisplay().getElement());

            // Error handler
            guac.onerror = function(error) {
                alert(JSON.stringify(error));
            };

            param = "height=768&width=1024&protocol=ssh&port=22&hostName=172.17.5.9&userName=test&password=test";
            // httpServlet request params Connect
            guac.connect(/*param*/);

            // Disconnect on close
            window.onunload = function() {
                guac.disconnect();
            }
