In the Settings->General screen in a single site installation of wordpress, there are two field named “wordpress address (URL) and the web site address (URL). They are important because they control the wordpress that your site is located. They control the display of the URL in the management section of your page, as well as the front-end, and all use the wordpress code.

The site address (URL) is set to the desired address in their browser type to your wordpress blog.

There are four simple ways to change the URL of the web site manually. Any of these methods will work and perform the same function.

In the following notes that ‘WP families’ and ‘home’, please refer to the web site address (URL) or you want what type of visitor in their browser. The SITEURL ‘WP’ and ‘siteurl’ please refer to the “wordpress address (URL)” or “address where your wordpress core files reside.

Edit wp-config.php

It is possible to manually set the site URL in the config.php file WP.

These two lines are added to your WP-config.php with the example.com” is the correct position, your site

is defined (‘SWP home, http://example.com’);
definition (‘SWP of http://example.com’); SITEURL”,
this is not necessarily the best solution, it just hardcoding the values into the site itself. You will not be able to edit them in the General Settings page, then use this method.

Edit functions.php

If you have access to the site via FTP, this method will help you to quickly obtain a site back up and running, if you change these values are not correct.

1. The FTP site, and obtain a copy of the theme’s functions.php file. You’re going to edit it in a simple text editor, and upload it to the site.

2. Add these two lines in the file. Immediately after the initial “<?php” line in

the update option (the siteurl’, ‘http://example.com’;
update option (the ‘home’, ‘http://example.com’);
use your own URL instead of the example.com is obvious.

3. Upload files to your web site, at the same location. Filezilla offers a convenient “Edit” feature to complete all of these rapidly; if you can use the system to do so.

Note: If your theme does not have a functions.php file to create a new text editor. Add the php tags and the two lines using your own URL, instead of example.com:.

<?php
update option,”,’ siteurl http://example.com’);
update option (the ‘home’, ‘http://example.com’);
->
upload to your theme directory. Delete Row or delete the file, the web site is up and running.

>>>

Here are some of the extra steps, you can transfer a LAN-based wordpress website into an externally accessible sites, but also allows editing of the wordpress web site from the internal LAN.

Two of the most important keys in the router/firewall modifications and wait 10 minutes after the change in the end

-use ssh to log in to your server (nm is a server-installed text editor)
– in the nano /var/log www/book/wp-content/themes/twentyeleven/functions.php
– just add a row to the <?php

update option,”,’ siteurl http://your.site.url:port/yourblog’);
update option (the ‘home’, ‘http://your.site.url:port/yourblog’);
– refresh your web browser using your external site url

http://your.site.url:port/yourblog
– USD nano /var/log www/book/wp-content/themes/twentyeleven/functions.php
– Delete those lines. You have just added (or comment)
– Access your router (the pfsense, other routers should have similar settings, look for/against)
– added to the Firewall/NAT table, a line is such a

wide area network/TCP/IP port/LAN, the server’s IP/80 –
added to the firewall/Rules form a line like this

* TCP//port/LAN, the server IP/Port /*
– uncheck this check box, the system/Advanced/Network Address Translation/Disable NAT thought

disabled automatically creates a NAT redirection rules for access to your public IP address, on your internal network. Note: You can only think about port forwarding” type of goods and does not work for large range > 500 ports. ”
And then to do something, for ten minutes, when you come back to look at the external url by http://your.site.url:port/yourblog lan browser of the page up correctly.

Relocate method

WordPress supports the auto-positioning method is intended to be a quick help for a site’s work when a site migration from one server to another.

, the re-positioning is defined as the real WP-config.php (see next section), the following code in the wp login, php will take action: if (as defined in the function”)&& relocation Relocation) {// mobile flag set
if (isset function $_SERVER [000 paths”)&& (in server [000 paths” ]! = $_SERVER ”PHP_self”])
$_SERVER ”PHP_self”] = .str_replace function $_SERVER [‘path”, ”’ $_SERVER PHP_self”);

in the url = dirname (set in the url scheme (the ‘http://’. $_server [000] HTTP host. [ $_server’ PHP_Self”)
($); if the url _ ! = ‘siteurl’ option (())
update (”, siteurl url);
]

Step
1. Edit the wp-config.php file.

2. The “definition” of the statement (the comment line, said: “All of this, stop editing! “), Insert a new line, and type: definition (the ‘Transfer’, true);

  2. Wp: in addition to the siteurl” and “home” as mentioned above, there are a number of other options, it also needs to be changed,
  3. such as the upload path”, and the number of plug-in item (depending on whether you have installed, such as a small part, statistics, dmsguestbook, site map, etc.)

Take care of your replacement, make sure you know the meaning of the fields, and then change it. Please refer to the important GUID note below for an example of what not to change.
  6. Please note that if you find that your old URL database option in the form of the “Dashboard” of incoming links, you can choose to ignore or delete it. This is because not using WP 3.8.
  7. How to connect your wordpress blog: Moving to a new area – use the export/import feature to move a blog to a new domain
  8. important note the GUID
  9. , do the above and changing the URL directly in the database, you will have instance URL is located in the heart of the “guid” column
  10. of the table in the WP posts.
  11. It is very important that you cannot change the contents of this field.
  12. “On Behalf Of” the GUID Globally Unique Identifier”. This is one of the areas with the aim of maintaining an identifier, the position of a) is unique in the entire space and time, and b), at any given time will not change. The GUID field is primarily used for creating a wordpress feeds.
  13. When a feed reader read the feed, it uses the GUID field lets you know if there is a specific project. This is in a variety of ways, but the most commonly used method is to simply save a list of GUID, it has been shown, and “Mark As Read” or similar.
  14. Therefore, change the GUID, it means that many of the feedreaders suddenly will display your content on the user’s card reader, as if it were a new content that can be annoying for your users.
  15. In order to enable the GUID field set to “global” is unique in that it is a widely accepted convention in the URL or some representative URL is used. Therefore, if you have your own example.com so you are the only one use of the example.com and therefore it is unique to you and your site. This is why wordpress use permanent link, or some form of documentation, the GUID.
  16. However, the second part is that the GUID must never be changed. Even if you switch the domain for the post, remains the same, even if it is in a new location. Feed readers is transferred to your new feeds when you change the URL should still know that they already know some of your posts, as a result, the GUID must remain unchanged.
  17. Never, ever, to make changes to its content GUID column, and in any case.
  18. Note: If the default upload folder needs to be changed to a different location, then any of the media URL will need to change the content of the posts table. For example, if the default upload folder is changing, from the wp-content/upload images:
  19. Update wp position post content = replacement (post content, thousands of www.domain.com/wp-content/uploads’,’www.domain.com/images’);
