Question

我有一些php脚本，shell_execute一些bash脚本。在这个bash中我启动一个Xvfb-Session并在其中启动一些firefox并截取屏幕截图然后再次杀死firefox和xvfb。 它在Ubuntu 14.04服务器上。

在Ubuntu 14.04上更新到Mozilla Firefox 52.0.1之前，它一直运行良好。

但是自从firefox更新后，firefox崩溃并将大量内容写入/var/log/kern.log和/ var / log / syslog

当我使用＆＃34; php5-cgi test.php＆＃34;在控制台上调用这个php脚本时，它仍然运行完美。但是当我通过lightttpd从浏览器调用它时，它突然崩溃了。

在这个firefox中有一些新的插件容器进程。在一切都在一个firefox进程之前。

PHP脚本：

$token = date('Y-m-d-H-i-s') . '-a1sf24df4asd54';
$url = 'https://www.my-url.com';
$screenNo = (int) date('i') + 30;

$PID = shell_exec('./start-run-preview.sh ' . escapeshellarg($url) . ' ' . escapeshellarg($name) . ' 60 ' . $screenNo . ' ' . escapeshellarg($token) . ' >> logs/'.$token.'.log 2>&1 &');
echo 'Screen: ' . $screenNo . PHP_EOL;
exit;

start-run-preview.sh

echo "Starting XVFB on $XVFB_DISPLAY"
Xvfb :${XVFB_DISPLAY} -screen 0 ${XVFB_RES_WIDTH}x${XVFB_RES_HEIGHT}x24 -noreset -nolisten tcp 2> /dev/null &
XVFB_PID=$!

# Remove parent lock to prevent error message "firefox has been shutdown unexpectly..."
rm ~/.mozilla/firefox/${FF_PROFILE_DIR}/.parentlock

echo "Running firefox -profile ${FF_PROFILE_DIR} on $XVFB_DISPLAY "
DISPLAY=:${XVFB_DISPLAY} firefox -profile ~/.mozilla/firefox/${FF_PROFILE_DIR} -width $XVFB_RES_WIDTH -height $XVFB_RES_HEIGHT "$FF_URL" > /dev/null &
FF_PID=$!

echo "firefox running on PID $FF_PID"

我尝试在此二手firefox配置文件中禁用了Flash插件，但它没有帮助。我不知道该做什么或在哪里找到问题。

由PHP shell_exec触发的Xvfb中运行新的Firefox崩溃
