Installing Nagios

I had a heck of a time finding the config file for nagios. It’s under: /etc/nagios3/conf.d/localhost_nagios2.cfg

MySQL Not Starting On Reboot

http://stackoverflow.com/questions/9859381/how-make-mysql-start-automatically-linux-cli-only

I was able to to the following, based on the post above:

1. sudo apt-get install sysv-rc-conf
2. sudo sysv-rc-conf
3. mark the 6 column for mysqld or mysql.server (6 = reboot)

Note: I tried sudo update-rc.d mysql.server defaults and it didn’t work. It gave me the following error: System start/stop links for /etc/init.d/mysql.server already exist.

MySQL IF Statement Affect On Speed

if(`table`.`start`='0000-00-00','',`table`.`start`)

Go to TinyHttp.php and add the highlighted part (using your own URL of course):

$opts[CURLOPT_PROXY] = 'http://xxx.xxx.xxx.xxx:8080/';
try {
      if ($curl = curl_init()) {

Failed to connect to socket /var/run/dbus/system_bus_socket

Error: Can’t find out if NetworkManager is running: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory.

The following fixed the problem:

apt-get install dbus

(if you already have dbus installed: sudo service dbus start)

/etc/init.d/network-manager start

What caused the error?:

/etc/init.d/network restart

Could not initialize NMClient

** (process:17986): WARNING **: error: could not connect to NetworkManager

Fix: Try running with sudo.

For example: sudo nm-tool | grep DNS
