linxu下使用xvfb虚拟设备进行截图

这2种方法经测试都已经通过。
服务器版本是：ceontos5.4 64位系统。

一、Xvfb + html2image

yum install Xvfb
yum install xorg-x11-fonts*

wget http://www.ys250.com/src/html2image.x86_64.tar.gz
#wget http://www.ys250.com/src/html2image.i386.tar.gz
mv html2image /usr/local/
cd /usr/local/html2image
export LD_LIBRARY_PATH=./
mkdir -p /usr/X11R6/lib
ln -s /usr/share/X11/usr/X11R6/lib/X11

#通过运行Xvfb来模拟 x-server 端
Xvfb :1-screen0 1024x768x24 -nolisten tcp-audit 4-auth X1.cfg& export DISPLAY=:1 firefox

#生成google.com 的预览图片
/usr/local/html2image/html2image www.google.com gg.jpg

二、Xvfb + CutyCapt

yum install libXi-devel
yum install libXinerama-devel
wget http://dl.atrpms.net/el5-x86_64/atrpms/testing/qt44-4.4.3-10_4.el5.x86_64.rpm
wget http://dl.atrpms.net/el5-x86_64/atrpms/testing/qt44-x11-4.4.3-10_4.el5.x86_64.rpm
wget http://dl.atrpms.net/el5-x86_64/atrpms/testing/qt44-devel-4.4.3-10_4.el5.x86_64.rpm

rpm -ivh qt44-4.4.3-10_4.el5.x86_64.rpm
rpm -ivh qt44-x11-4.4.3-10_4.el5.x86_64.rpm
rpm -ivh qt44-devel-4.4.3-10_4.el5.x86_64.rpm
# qt44-devel 安装不上执行下面这句删掉lao的devel包
rpm -e qt-devel--nodeps --allmatches

vi /etc/profile
export QTDIR=/usr/lib64/qt44
export QTLIB=/usr/lib64/qt44/lib64
export QTINC=/usr/lib64/qt44/include
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export PATH=$QTDIR/bin:$PATH

source /etc/profile

svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
mv cutycapt/CutyCapt /usr/local/CutyCapt
cd /usr/local/CutyCapt
qmake
make

#使用xvfb-run脚本来管理Xvfb
wget http://www.ys250.com/src/xvfb-run.sh
mv xvfb-run.sh/usr/local/CutyCapt/xvfb-run.sh

#缺陷就是flash没解析出来

安装中文字体，可以从windows拷一些ttf文字到 /usr/share/fonts/truetype/目录
yum install fonts-chinese yum安装一个中文字体也行。
