這怎麼對指南使用Subversion來下載和安裝獨立的WordPress博客與他們的插件 ，方便快捷地從你的Linux 命令行界面 ， 簡單的更新一次。 它還詳細WordPress 的MySQL數據庫的安裝過程 。

好吧，我承認，我偏向於WordPress的！ 這個指南是一個完美的適合那些想推出他們的可濕性粉劑博客從車輛定位系統在最快的時間和設計未來的打樣。

也就是說，如果您使用其中一個成千上萬的其他平台上可以安裝使用Subversion，安裝過程不disimilar。 如果您有具體的問題，在任何平台上，發表評論，我會盡力幫助。 誰知道，我什至可以編寫特定的教程。

WordPressers -準備捆綁節省時間。

基本Web服務器的研製為WordPress

在第8部分：更快的車輛定位系統！ 設置的PHP，MySQL和XCache的 ，除其他外，我們安裝了顛覆。 在第11部分：安裝Nginx的（優於阿帕奇或Lighttpd）我們建立了Nginx的。 在第13部分：配置Nginx的多站點虛擬主機 ，我們加強了Nginx的文件結構，並允許多站點託管。 在第14部分：安裝WordPress的關於nginx的（FURLs＆緩存），我們tweaked Nginx的優化其服務的WordPress。 如果你錯過任何人，折回。

到年底，本教程中，我們將WordPress的工作。 甜蜜。

這是您的要求： -

• 創建數據庫
• 安裝WordPress
• 添加首選插件
• 輸入您的主題
• 數據遷移

如果你想要一個全新的博客，你會進行首4個的階段。

打開終端CLI的事情。 如果您使用的是Windows在本地，也沒有這樣做，創建遠程服務器訪問，安全，緩解巨大的登錄過程。 為此，請閱讀第3部分：設置遠程加密連接與第4部分：隱藏數據及簡單登錄- SSH的和PuTTY的 。

...雖然我嘮叨，如果你尚未準備好，你也應該進行第6部分：鎖LINUX的-的SSH和一個iptables防火牆 。

創建MySQL數據庫為WordPress從命令行

登錄到MySQL的： -

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

...and add the details you entered above into your new MySQL database. So, in the wp_config file, swap putyourdbnamehere , usernamehere and yourpasswordhere . Here's the original wp-config, before you change it:-

/** 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 .
