Install / Upgrade WordPress mit Subversion - VPS Bibel # 15

Dieses How-To Guide verwendet Subversion zum Download & Standalone WordPress-Blogs und ihre Plugins, schnell und einfach von Ihrem Linux-Kommandozeilen-Schnittstelle installieren, mit einfachen Updates danach. Darüber hinaus enthält die WordPress MySQL-Datenbank Setup-Prozess.

OK, ich gebe zu, ich bin auf WordPress voreingenommen! Und dieses Leitfadens ist es eine perfekte Lösung für alle jene, die ihre WP Blog von einer VPS in der kürzesten Zeit zu starten und für die Zukunftssicherung entwickelt.

Das heißt, wenn Sie mit einer der Tausenden von anderen Plattformen, die installiert werden, mit Subversion, kann die Installation nicht disimilar. Wenn Sie spezielle Fragen haben, auf jedem beliebigen Plattform, einen Kommentar abzugeben, und ich werde versuchen zu helfen. Wer weiß, vielleicht schreibe ich auch eine spezifische Anleitung.

WordPressers - Vorbereitung Bündel von Zeit zu sparen.

Essential Web-Server Vorbereitung für WordPress

In Teil 8: Schneller VPS! Bis PHP, MySQL & XCache unter anderem Set, installierten wir Subversion. In Teil 11: Installieren nginx (besser als Apache oder Lighttpd) richten wir Nginx. In Teil 13: Konfigurieren nginx Multi-Site-Virtual Hosts wir verstärkt die Nginx Dateistruktur und für Multi-Site-Hosting erlaubt. In Teil 14: Setup WordPress nginx (FURLS & Cache), feilten wir Nginx zur Optimierung ihrer serviert von WordPress. Wenn Sie eine dieser verfehlt, zurückzuverfolgen.

Bis zum Ende dieses Tutorials wird, haben wir WordPress arbeiten. Süß.

Hier sind Ihre Anforderungen: --

• CREATE DATABASE
• WordPress installieren
• add bevorzugten Plugins
• Importieren Sie Ihre Thema
• verlagern Daten

Wenn Sie ein neues Blog möchten, finden Sie die Durchführung der ersten vier dieser Phasen.

Öffnen Sie Ihr Terminal CLI Sache. Wenn Sie Windows lokal und nicht bereits geschehen, erstellen Remote-Server zuzugreifen, sicher und an der Anmeldevorgang einfach enorm. Dazu lesen Sie Teil 3: Einrichten einer Remote-Verbindung verschlüsselt und Teil 4: Hide Data & Simple Login - SSH und PuTTY.

... Während ich bohrende bin, wenn Sie noch nicht getan haben, sollten Sie auch durchführen Teil 6: LOCK LINUX - SSH & iptables-Firewall ein.

Nur noch eine letzte Anmerkung. throughout this guide. Ich meine zB Linux / MySQL-Benutzernamen und guvnr meiner Website waywiderweb.com in diesem Handbuch. Ersetzen Sie diese Werte mit Ihren eigenen

Richtig. Ready rollen.

Erstellen Sie eine MySQL-Datenbank für WordPress aus der Kommandozeile

Melden Sie sich MySQL mit: --

mysql -u root -p

Add your password, or the password we created when we installed MySQL in Part 8: FASTER VPS! Set Up PHP, MySQL & Xcache .

Now paste this lot, replacing your_wordpress_username , your_wordpress_password and wp_database_name with yours, and leaving the quote marks I've included for the password:-

grant all privileges on *.* to your_wordpress_username@localhost identified by "your_wordpress_password";
create database wp_database_name;
quit

Install WordPress on your Linux VPS Using Subversion

Let's go to the directory in which to install WordPress. I'm installing to my root directory, /home/public_html/waywiderweb.com/public , which I created in Part 13: Configure NGINX Multi-Site Virtual Hosts (the directory structure is explained most comprehensively in the video in Part 13.) If you want your blog to appear in a sub-directory, such as waywiderweb.com/blog, then use /home/public_html/waywiderweb.com/public/blog . Of course, change waywiderweb.com for your domain:-

cd /home/public_html/waywiderweb.com/public

If you created a test index.html file in Part 13: Configure NGINX Multi-Site Virtual Hosts , let's bin it:-

sudo rm index.html

Now we'll use the subversion command to install the latest version of WordPress. Ammend this version with any newer one. Leave the dot at the end, it's not a typo:-

sudo svn co http://svn.automattic.com/wordpress/tags/2.8.4 .

And create the WordPress config file:-

sudo mv wp-config-sample.php wp-config.php

Now let's connect the database. Open the WP config file:-

sudo nano wp-config.php

/** The name of the database for WordPress */
define('DB_NAME', 'putyourdbnamehere');

/** MySQL database username */
define('DB_USER', 'usernamehere');

/** MySQL database password */
define('DB_PASSWORD', 'yourpasswordhere');

While you're in there, for added security, find:-

$table_prefix  = 'wp_';

...and swap wp_ to something unique.

Save and quit (CTRL-X, 'y' to confirm and hit Return.)

Run WordPress Install & Connect the MySQL Database

Open your blog in a browser, so for me, for instance, that's www.waywiderweb.com. Enter a few details, log in and change the password the WP installer gave the newly created Admin user. You should really delete Admin entirely and replace with another user, but that's another story.

Batch-install WordPress Plugins using Subversion

This bit really rocks my roger. If you've got a bunch of blogs with pretty much the same plugins, you may just save a month of Sundays here.

Back at the CLI, goto the plugin directory:-

cd /home/public_html/waywiderweb.com/public/wp-content/plugins

Let's edit our plugin list. Keep that dot:-

sudo svn propedit svn:externals .

OK, so there's only Akismet in there. Let's add some more. Go to the WordPress Subversion plugin repository and take your pick. For each plugin you have 2 download choices:-

• tags - stable releases by version, so choose generally the latest
• trunk - latest version, bleeding edge, occasionally buggy

Personally, I run the trunk versions, for the simple reason that I can install or upgrade all plugins by issuing a simple command, thereafter. If a plugin gives me any gip, I simply delete it and its reference in my svn WP plugins list, else I replace its trunk with a tag. Of course, if you use the tags option, you have to keep editing your plugins file, which largely negates having it in the first place.

So, here's an example externals file that I've thrown together. Note the name of each plugin before the link, 'cos you must have that identifier. If you followed Part 14: Setup WordPress on NGINX (FURLs & Cache), you'll notice I've included the WP Super Cache plugin:-

akismet http://plugins.svn.wordpress.org/akismet/trunk/
wp-phpmyadmin http://svn.wp-plugins.org/wp-phpmyadmin/
wp-super-cache http://svn.wp-plugins.org/wp-super-cache/trunk/

TIDY TIP: If you're happy with trunks, in the WP Sub Vers Repos, look down the list and right mouse click > Copy Link Location , then paste it to a text file, adding the name of the plugin before the link. Do that to as many plugins as you want, then simply paste /trunk at the end of each link. Then paste the lot to your svn plugins file. Much quicker. If you want tagged versions, it's the long way round, 'cos the tags differ. Then again, for some plugins, there is no svn listing at all, so those have to be included the old-fashioned way.

Right, with your plugins file edited, saved and closed, now type:-

sudo svn update

Take tea.

Import Your WordPress Theme

Set Linux Folder Permissions

If you didn't in Part 13: Configure NGINX Multi-Site Virtual Hosts , set your folder permissions, allowing SFTP access, substituting guvnr with your user name:-

sudo chown -R guvnr:webmasters /home/public_html

Add the theme

If you are using a regular theme, add it in the usual WordPress way.

Alternatively, if you want to use a previous, adapted theme:-

Open an SFTP client like FileZilla or WinSCP, browse to your remote themes directory - something like /home/public_html/waywiderweb.com/public/wp-content/themes/ - and upload your bespoke theme.

Either way, you can now enable the theme in the regular way, at http://your_blog.com/wp-admin/themes.php .

Relocate Your Existing WP Blog Data

...If you've got any to relocate! For new blogs, skip this bit.

You can do this by exporting from the old and importing into the new database. In my experience it's far easier to use WP's export/import tools, which also optimises the data.

Surf to your original blog:-

http://www.your_ORIGINAL_blog.com/wp-admin/export.php

...or Dashboard > Tools > Export .

And Download export file .

Now goto your new blog:-

http://www.your_ORIGINAL_blog.com/wp-admin/import.php

...or Dashboard > Tools > Import .

Click the WordPress option, choose the exported file and Upload file and import . Prompted, check the box Download and import file attachments .

If you receive any errors, that's probably a permissions problem. For example, I got this:-

Unable to create directory /home/public_html/waywiderweb.com/public/wp-content/uploads/2009/04. Is its parent directory writable by the server?

...So we'll take ownership of the directory:-

sudo chown -R guvnr:webmasters /home/public_html/waywiderweb.com
sudo chmod -R g+w /home/public_html/waywiderweb.com

And now have another go with Upload file and import , opting for our user imports and checking the box Download and import file attachments .

If you'd prefer to relocate select data, there's always wp-phpmyadmin .

Activating WP Super Cache

Activate in the usual WordPress way, and cash in on the groundwork of Part 13: Configure NGINX Multi-Site Virtual Hosts . Cash in, geddit! Sorry.

Updating WordPress Plugins

While 2.7 brought in some top functionality with the WordPress auto-updating, pretty much negating using Subversion to update the platform or plugins, there will be occasions when it's still faster to upgrade plugins this way.

Particularly this will be the case after a platform upgrade, when plugins race to bring out updates, they can be upgraded together using Subversion:-

sudo svn update

Sending Live a Relocated WordPress Blog

Refer to Part 19: Moving Day! How to Move Your Blog or Site for the best way to do this, with the least downtime or other sticky problems.

Rinse & Repeat

Follow this process for your entire blog farm.

Just Round the Corner

For WordPress, that's all the specifics taken care of, I think. You tell me, what have I forgotten? Lemme know and I'll write it up.

More generally, I'll wrap up the series - Set Up Unmanaged VPS (4 Newbies) .. The VPS Bible - by showing how and why to setup Google Apps in Part 17: Google Apps for Domain-Specific Email , which keeps our VPS server resources jealously focussed on our sites and blogs, before running down the all-important moving day checklist mentioned above. Then there'll be a handy backup guide before linking a heap of top resources for Linux newbies in Part 20: Blogroll, Links, Credits, Resources .
