Upgrade WordPress on VPS / Linux

My last WordPress post has been a while ago but I’m using this almost daily. There have been some edit, hacks and what not along the way but I must say I’m pretty satisfied still with this software. In addition to installing a FTP service on my Linux VPS today I discovered, with yet another…

There are a little bit more steps mainly because of SELinux but it’s still simple. Follow the below instructions to reset your CentOS root password. Like I noted with the previous…
