CutyCapt 是Linux下抓取网页截图的软件,需要先安装QT,以下为Centos 5.8 64 Bit 安装
需求:有些网站长度过长,截图太慢.
例如:163的网站,要抓取就需要多次截图,比较麻烦
原来想用命令curl抓取网页内容,但是发现好多链接图片是无法抓取过来的.
1.增加atrpms的yum源
vi /etc/yum.repos.d/atrpms.repo
[atrpms]
baseurl=http://dl.atrpms.net/el$releasever-$basearch/atrpms/testing
enabled=1
gpgcheck=0
2.安装qt47及相应包(下面的这些安装包,下载下来强制安装吧,上面那个源里面有两个版本,容易造成版本冲突)
qt47-4.7.2-1_18.el5
qt47-devel-4.7.2-1_18.el5
qt47-x11-4.7.2-1_18.el5
qt47-webkit-4.7.2-1_18.el5
qt47-webkit-devel-4.7.2-1_18.el5
phonon-backend-gstreamer-4.7.2-1_18.el5
rpm -Uvh --force --nodeps qt47-devel-4.7.2-1_18.el5.x86_64.rpm
3. 安装 CutyCapt
svn安装
#yum install subversion
svn co https://cutycapt.svn.sourceforge.net/svnroot/cutycapt
mv cutycapt/CutyCapt /usr/local/cutycapt
cd /usr/local/cutycapt/
#这步网上很多都是直接用qmake,但是我的有问题,因为qmake是qt3的
qmake-qt47
make
#* 再执行make的时候有可能会报如下错误
# make
g++ -Wl,-O1 -o CutyCapt CutyCapt.o moc_CutyCapt.o -L/usr/lib64/qt47 -lQtWebKit -lQtSvg -L/usr/lib64/qt47 -lQtGui -lQtNetwork -lQtCore –lpthread
/usr/lib64/qt47/libQtWebKit.so: undefined reference to `sqlite3_prepare16_v2'
/usr/lib64/qt47/libQtWebKit.so: undefined reference to `sqlite3_column_value'
collect2: ld returned 1 exit status
make: *** [CutyCapt] Error 1
解决:
升级到sqlite-3.6,不要卸载在安装 #如果是6.0,默认就是3.6
yum update sqlite
#* make完就生成了CutyCapt这个可执行文件。
4. 运行环境
# ./CutyCapt --help
CutyCapt: cannot connect to X server
#* 网上很多都是要在装个xvfb-run.sh的,其它不用这么麻烦:
echo "export DISPLAY=':1.0'" >> /etc/profile
source /etc/profile
vncserver
