If you are using cPanel/WHM, and have ownCloud installed. You might soon realise that delete actions are not working. The reason is because it fails due to DELETE methods that are not going through.
The fix is to modify the .htaccess file, at end of file: ADD
<Limit GET POST>
order allow,deny
allow from all
</Limit>
<Limit PUT DELETE>
order allow,deny
allow from all
</Limit>
What is it?
Sudoers is a list of users which may execute root commands. A sudoers file is made up of two types of entries, aliases and user specifications
How to set it up?
Do a visudo on command line, then add the user to the list as below.
If you want to enter the user’s password before executing the command:
myuser ALL=(ALL) ALL
And without a password:
myuser ALL=(ALL) NOPASSWD: ALL
I was developing a french website for a customer yesterday and at the same time, when I was templating the site to php, I found out that all the french accents got turned into a question mark, � <– this really..
I already had UTF-8 in my headers
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
and it was still not working.
It turns out that I had not saved the file in UTF-8, so I had to open up Notepad++ which is my main coding IDE, and go to Encoding -> Convert to UTF-8 without BOM
Solved!
My MySQL Server went down today, which meant that my website was not working as well. When I checked, it clearly replied:
[root@sdb ~]# service mysqld status
mysqld is stopped
I automatically checked for the uptime of the server to see that it was a few hours ago. A chkconfig revealed that I forgot to add mysqld to autostart in run levels 2-5. Serious mistake, but since I reinstalled the server a few days ago, comprehensible.. i guess!
mysqld 0:off 1:off 2:off 3:off 4:off 5:off 6:off
I then switched it to autorun and started the service via the following commands:
chkconfig mysqld on
service mysqld start
..The big question why did the server reboot?
I checked the logs at /var/log/messages to see the reason of the reboot.
less /var/log/messages
which revealed

Happy as ever, I wrote a script to auto start a service if they have been found as not running, even if the server did not reboot. View it here.
If you are running a service and for some reason the service gets broken, you will want it to automatically restart. For that reason, I have created a script as below. Feel free to amend the array autoservice as needed because in my case it is monitoring mysqld, cherokee and squid.
#!/bin/bash
#Add values to the array autoservice seperated by spaces
autoservice=(mysqld cherokee squid)#the code
export PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
for i in “${autoservice[@]}”
do
:
service $i status # > /dev/null
if [ $? -eq 0 ]; then
echo $i “Running..”
else
service $i restart
fi
done
Created in /scripts/checkService.sh, you need to chmod 777 the file and add it to crontab to run every 5minutes via the following:
chmod 777 /scripts/checkService.sh
crontab -e
add this line to run it every 5 mintues
