网上判断两数组是否相同BUG代码：
<?php $ar1 = [1,2,3,4]; $ar2 = [1,2,3,4,5]; var_dump(array_diff($ar1,$ar2)); var_dump(array_diff($ar2,$ar1)); ?>
修复：
<?php
$ar1 = [1,2,3,4];
$ar2 = [1,2,3,4,5];
if(count(array_unique($ar1))!=count(array_unique($ar2))){
echo "not eq";
exit;
}
var_dump(array_diff($ar1,$ar2));
var_dump(array_diff($ar2,$ar1));
?>

vim /usr/sbin/sysv-rc-conf
sub update_link 函数下
原代码：
return 1 if $sk eq ”;
修改为
unlink “/etc/systemd/system/multi-user.target.wants/$sn.service”;
return 1 if $sk eq ”;
return 1 if $sk eq ‘K’;
ubuntu 16.04 测试通过 ， 目前 只做了 off 操作修改 on 操作有时间再修改
另附一个已经改好的
wget https://dl.eff.org/certbot-auto –no-check-certificate

最后添加定时任务：
0 3 */5 * * /opt/certbot-auto renew #每5天定时更新证书
经测试 在centos6下会出现此问题， 经测试为date bug
临时解决办法：
/usr/sbin/openvas-scapdata-sync
oval_timestamp=`xsltproc “$SCAP_RES_DIR/oval_timestamp.xsl” “$ovalfile” | date “+%s” -f -`
修改为
oval_timestamp=`xsltproc “$SCAP_RES_DIR/oval_timestamp.xsl” “$ovalfile” | sed ‘s/T/ /’ | date “+%s” -f -`
#复制异地的scap-data文件，然后再执行
openvas-scapdata-sync --migrate #刷新数据
#cert sync 对应文件
/usr/bin/rsync -ltvrP --delete --exclude /cert.db --exclude private/ rsync://feed.openvas.org:/cert-data /var/lib/openvas/cert
