How to Set Up a Mirror WordPress Site

Decide where to host your mirror site. If you only need local access to your site, you can host the installation locally on your personal computer. Using a local host allows instant changes without an Internet connection. Remote hosting, through a web server, gives you access from anywhere in the world with an Internet connection. It is best to test user functionality before moving a change to your production site.
Set your mirror URL. Log into your domain name control panel and add a sub-domain for your mirror site. If you are using a local host, install a program like WAMP and set up a directory localhost that you can access through your web browser. If you are using a remote host, choose a domain like mirror.yoursite.com or test.yoursite.com to use for hosting.
Install WordPress into the mirror directory. If you are skilled at editing databases and php files, you can copy the database and WordPress directory directly to the new host. If not, use the WordPress installation wizard or your hosting WordPress installation tool to setup a new WordPress site hosted at your new URL.
Copy your production WordPress site to the new installation. WordPress has a user friendly export/import function that will automate the data transfer. In the WordPress administration panel, you can find the export and import functions under the 'Tools' menu.
Copy your template and set your file permissions. Using an FTP client, copy your theme files and set your file permissions on the mirror site to match your production site. Also, make sure you have a .htaccess file that is writable by WordPress with 775 file permission so your new site will function properly.

How to Set Up a Free Proxy (6 Steps)

Sign up for server space. If you already have a web server, you can skip this step. If you do not, you can sign up for either a free hosting account for limited bandwidth or a paid host for higher or unlimited bandwidth. Make sure you have FTP access to your hosting account so you can upload files to the server and that your server can run PHP. Either way, take note of your FTP user name and password before moving on.
Install an FTP program on your computer. Filezilla is the most popular free FTP program. It can be downloaded from Sourceforge.net. Follow the installation instructions for your computer. Make sure to download the right version for a Mac, Windows, or Linux computer.
Download PHProxy for free from Sourceforge. PHProxy is a free proxy server software package based in the PHP programming language. It is easy to install on any web server. Download the free installation package onto your desktop. You can test the software at phproxy.org.
Log in to your hosting account using Filezilla and navigate to your public_html directory. The public_html directory is where web pages are hosted on your server space. Choose one of your hosted domain folders and create a sub directory called '/proxy.' Doing so will install the program to yoursitename.com/proxy (replace yoursitename with your website's name).
Upload the entire PHProxy package into the /proxy folder on your server. Be sure to unzip the package and upload every file. Once the files are uploaded, use Filezilla to set the file permissions to 666, which will allow you to read the file from a web browser.
Go to yoursitename.com/proxy and you can use your proxy from any computer with Internet access. If you are concerned about other people using your proxy, you can change the directory name from /proxy.
