Guacamole——2.本地安装Guacamole

Guacamole 分为两个部分:一部分是guacamole-server，它提供guacd 代理和关联包；另一部分是guacamole-client，它通过servlet容器在Tomcat上给客户端提供服务。

编译guacamole-server

       guacamole-server包含所有Guacamole连接远程桌面所需的本地、服务端组件。它还提供一个通用的C库——libguac、所有其它本地组建的依赖、以及为每个支持的协议单独的库和Guacamole的核心 guacd。，

      guacd是运行在Guacamole服务端上代理服务的守护进程，接收用户请求Guacamole web应用的隧道连接，然后代替用户连接远程桌面。编译guacd生成可执行文件，它可以手动执行，如果你愿意，也可以让它开机自启动。

      为了编译guacamole-server，你需要C编译器（例如：GCC）以及guacamole-server所依赖的库。一些依赖是必需的，还有一些是可选择的。但可选择的那些依赖可以增加一些额外的特性。

必需依赖

为了编译guacamole-server，你需要这些包：Cairo, libjpeg, libpng, and the OSSP UUID。这些包在任何情况下都是必须安装的，没有它们Guacamole就编译不了。

库名

特性

Cairo

Cairo 是被libguac 用来绘图的. 没有它Guacamole就实现不了此功能。

Debian / Ubuntu package

libcairo2-dev

Fedora / CentOS / RHEL package

cairo-devel

libjpeg-turbo

libjpeg-turbo 为libguac 提供 JPEG 的支持. 没有它Guacamole就无法编译。

Debian / Ubuntu package

libjpeg62-turbo-dev

Fedora / CentOS / RHEL package

libjpeg-turbo-devel

如果libjpeg-turbo 在你的平台上不可用, 并且你不希望用源码编译它, libjpeg 也会照常工作，只是速度不会那么快。

Debian / Ubuntu package

libjpeg62-dev

Fedora / CentOS / RHEL package

libjpeg-devel

libpng

libpng 被 libguac 用来写PNG 图像, 它是Guacamole 协议使用的核心图像类型. Guacamole 没有libpng就不能正常运转.

Debian / Ubuntu package

libpng12-dev

Fedora / CentOS / RHEL package

libpng-devel

OSSP UUID

OSSP UUID 被libguac 用来设计每一个Guacamole连接唯一的 ID. 这些唯一的ID是连接分享的基础。

Debian / Ubuntu package

libossp-uuid-dev

Fedora / CentOS / RHEL package

uuid-devel

可选择依赖

可选择性的依赖决定Guacamole哪些支持的协议会被安装，并且决定关于这些协议的额外特性是否可用。

Guacamole目前支持的协议有：VNC、RDP、SSH和telnet。每一种协议对应一个独立的库，如果你安装了它对应的依赖，这些独立的库就会随着guacamole-server被编译。

VNC的支持依赖于libvncclient，它是libVNCServer的一部分，RDP的支持依赖于FreeRDP 1.0或更高的版本，SSH的支持依赖于libssh2，telnet依赖于libtelnet。Pango是一个字体、文本布局库，为SSH和telnet提供支持。

Library name

Features

FreeRDP

FreeRDP is required for RDP support. If you do not wish to build RDP support, this library is not needed.

Debian / Ubuntu package

libfreerdp-dev

Fedora / CentOS / RHEL package

freerdp-devel

Pango

Pango is a text layout library which Guacamole's SSH and telnet support uses to render text. If you do not wish to build SSH or telnet support, this library is not needed.

Debian / Ubuntu package

libpango1.0-dev

Fedora / CentOS / RHEL package

pango-devel

libssh2

libssh2 is required for SSH support. If you do not wish to build SSH support, this library is not needed.

Debian / Ubuntu package

libssh2-1-dev

Fedora / CentOS / RHEL package

libssh2-devel

libtelnet

libtelnet is required for telnet support. If you do not wish to build telnet support, this library is not needed.

Debian / Ubuntu package

libtelnet-dev

Fedora / CentOS / RHEL package

libtelnet-devel

libVNCServer

libVNCServer provides libvncclient, which is required for VNC support. If you do not wish to build VNC support, this library is not needed.

Debian / Ubuntu package

libvncserver-dev

Fedora / CentOS / RHEL package

libvncserver-devel

PulseAudio

PulseAudio provides libpulse, which is used by Guacamole's VNC support to provide experimental audio support. If you are not going to be using the experimental audio support for VNC, you do not need this library.

Debian / Ubuntu package

libpulse-dev

Fedora / CentOS / RHEL package

pulseaudio-libs-devel

OpenSSL

OpenSSL provides support for SSL and TLS - two common encryption schemes that make up the majority of encrypted web traffic.

If you have libssl installed, guacd will be built with SSL support, allowing communication between the web application and guacd to be encrypted. This library is also required for SSH support for the sake of manipulating public/private keys.

Without SSL support, there will be no option to encrypt communication to guacd, and support for SSH cannot be built.

Debian / Ubuntu package

libssl-dev

Fedora / CentOS / RHEL package

openssl-devel

libvorbis

libvorbis provides support for Ogg Vorbis - a free and open standard for sound compression. If installed, libguac will be built with support for Ogg Vorbis, and protocols supporting audio will use Ogg Vorbis compression when possible.

Otherwise, sound will only be encoded as WAV (uncompressed), and will only be available if your browser also supports WAV.

Debian / Ubuntu package

libvorbis-dev

Fedora / CentOS / RHEL package

libvorbis-devel

libwebp

libwebp is used by libguac to write WebP images. Though support for WebP is not mandated by the Guacamole protocol, WebP images will be used if supported by both the browser and by libguac.

Lacking WebP support, Guacamole will simply use JPEG in cases that it would have preferred WebP.

Debian / Ubuntu package

libwebp-dev

Fedora / CentOS / RHEL package

libwebp-devel

获取源代码

      你可以在Guacamole的项目网站上获取一份guacamole-server 源码。最新的稳定发行版是经过了Guacamole小组的测试，认为适合公众使用的版本。从项目网站上下载的.tar.gz格式压缩包，可以用过下列命令解压：

$ tar -xzf guacamole-server-0.9.9.tar.gz$ cd guacamole-server-0.9.9/$

如果你想得到最新的代码，并且不关心它没有经过稳定发行版一样严格的测试，你也可以用Guacamole团队在Github上的仓库里克隆一份:

$ git clone git://github.com/glyptodon/guacamole-server.gitCloning into 'guacamole-server'...remote: Counting objects: 6769, done.remote: Compressing objects: 100% (2244/2244), done.remote: Total 6769 (delta 3058), reused 6718 (delta 3008)Receiving objects: 100% (6769/6769), 2.32 MiB | 777 KiB/s, done.Resolving deltas: 100% (3058/3058), done.$

编译流程

      当你把guacamole-server源码下载下来，并且解压后，就可以运行configure命令。这是一个被GNU Autotools自动触发的shell脚本，GNU Autotools是一种流行的编译系统，也被Guacamole 所使用。正在运行的configure 命令会判断哪些库在你的系统上有效，并且会根据你所安装的依赖选择合适的组件来编译。
