centos6 截图 CutyCapt

install cutycapt

安装完后会有/usr/bin/CutyCapt和/usr/bin/xvfb-run

# yum install -y epel-release
# yum install -y CutyCapt

example

$ xvfb-run --server-args="-screen 0, 1024x768x24" ./CutyCapt --url='http://baidu.com' --out=/tmp/baidu.png

报错处理

$ /usr/bin/xvfb-run --server-args="-screen 0, 1024x768x24" /usr/bin/CutyCapt --url='http://baidu.com' --out=/tmp/a.png
process 10606: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/var/lib/dbus/machine-id": No such file or directory
See the manual page for dbus-uuidgen to correct this issue.
  D-Bus not built with -rdynamic so unable to print a backtrace
/usr/bin/xvfb-run: line 181: 10606 Aborted                 DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@" 2>&1

使用命令生成machine-id即可

dbus-uuidgen > /var/lib/dbus/machine-id
