How to setup wordpress on the CentOs server

First you have to download the wordpress, create the database and configure as required.

Mostly we require a theme to install on wordpress, database and some data :-)

Downalod the latest wordpress code with


Its easy to set connect data base and operate on it using the sqlyog. So if you want to do lot of activity on database then I suggest to go for sqlyog.

Now Unzip the wordpress file using the command > unzip

Move the wordpress folder to www directory

mv wordpress/ /var/www/

Now add the site to your httpd config file


Change the server folder permissions to the below

Find all directories in this directory and set their permissions to 755:

sudo find . -type d -exec chmod 755 {} \;

Do it again, but for files and 644:

sudo find . -type f -exec chmod 644 {} \;

Give the uploads folder back to apache (or www-data):

sudo chown -R apache:apache ./wp-content/uploads

In my case, I also needed to give existing folders starting with backup- back to apache as well, as that’s where our backup plugin placed its database backups:

sudo chown -R apache:apache ./wp-content/backup-*

Finally, if it’s a Multisite install, give the blogs.dir directory back as well:

sudo chown -R apache:apache ./wp-content/blogs.dir
That should do it. No guarantees that you’ll never be hacked again, but it should certainly be less likely.
