Well,first i should thanks remi for his hard work.

Now the problem in front of myself is how to build the website.

After I add remi repo to system's etc profile,I execute yum install nginx mysql php phpmyadmin and so on.

But i don't know where i can configure the phpmyadmin,you know i want to create a database.

and just one more question,how can i set my home page to wordpress?

Now my site's first page is epel's welcome to nginx.It told me /usr/share/nginx/html how can i change the nginx.conf in order for correct displaying?

thanks.
