#xvfb-run

[vinh-tran]

which: no xauth in ((null)) xvfb-run: error: xauth command not found

I use xserver and webkitoimage to export a webpage to image. I deployed it to centos server. On this server, I used apache for web server.

To export a page to image we will run command:

/usr/bin/xvfb-run --server-args="-screen 0, 1280x1024x24" /usr/local/bin/wkhtmltoimage --use-xserver http://localhost/print/voucher/322?voucher=803 /tmp/tmp1369141170.png 2>&1

After apache call an action which have

echo shell_exec(' /usr/bin/xvfb-run --server-args="-screen 0, 1280x1024x24" /usr/local/bin/wkhtmltoimage --use-xserver http://localhost/print/voucher/322?voucher=803 /tmp/tmp1369141170.png 2>&1'); It throw the error: which: no xauth in ((null)) xvfb-run: error: xauth command not found

I go around and cannot see any articles in internet. I go around and check on the bash script file of xvfb-run and saw the lines:

if ! which xauth >/dev/null; then error "xauth command not found"     exit 3 fi

Look like they will get the path of xauth with the role of process user/group. On this case, apache dont have enough right/permission so it return null.

What I did to fix this issue:

1. Comment out the if statement

#if ! which xauth >/dev/null; then #error "xauth command not found" #    exit 3 #fi

2. replace xauth in the bash script by the absolute path to the file

line 156: XAUTHORITY=$AUTHFILE /usr/bin/xauth source - << EOF >>"$ERRORFILE" 2>&1

line 174: XAUTHORITY=$AUTHFILE /usr/bin/xauth remove ":$SERVERNUM" >"$ERRORFILE" 2>&1

And done!
