Upgrading DELL firmware

          One of the few maintenance tasks often neglected by system administrators, is that of upgrading server firmware. Whether that be BIOS, Network cards, RAID or any other firmware, these subsystems might never see an update during the life time of a server.

Luckily, Dell makes this very easy under Red Hat / Centos. Here are the steps:

# wget -q -O – http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash
# yum -y install firmware-tools.noarch
# yum -y install $(bootstrap_firmware)
# update_firmware --yes
# reboot

You might need to apply the last three steps a few times between reboots, as not all firmware is applied in the same go.

Also, you need to reboot your machine. No cold boot, shutdown, power off etc, just a nice warm reboot. :)

Create Wi-Fi Hotspot in Windows

Open your cmd.exe with Administrator account and paste these command line after line

netsh wlan set hostednetwork mode=allow ssid=hotspot key=password keyUsage=persistant

netsh wlan start hostednetwork
 

Thats it , now scan your Wi-Fi for hotspot. You can use any where , you just require wireless router/modem.

PHPMyAdmin in your CentOS 6.X

Open your terminal and EPEL Repo

 wget http://epel.mirror.net.in/epel/6/i386/epel-release-6-8.noarch.rpm 
 rpm -Uvh epel-release-6-8.noarch.rpm 

Then Add Remi

rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm 

Now open /etc/httpd/conf.d/phpMyAdmin.conf file and enter the address field with address from where you want access PhPMyAdmin remotely cause it is accessed by default from localhost only.

vim /etc/httpd/conf.d/phpMyAdmin.conf
 

Next restart your httpd with

service httpd restart 
 

Open your browser and type there as localhost/phpmyadmin and login with your mysql username and password. If you want browse remotely then your IP must allowed( added ) from above mentioned configuration file. Note: This information has taken from several sources.
