sudo apt-get install apache2
sudo apt-get install php5
sudo apt-get install libapache2-mod-php5
sudo apt-get install mysql-server php5-mysql
sudo /etc/init.d/apache2 restart

 
I had to search various sites to solve this problem so I figured I would pass on the knowledge in one succinct solution.

How to get WordPress permalinks / pretty links to work in Ubuntu 10.10 with Apache2:

By the way, this should be the same in Ubuntu 10.04 as well, but I haven't actually tested it there as well.

1. Manually create a ".htaccess" file and save it in your main WordPress directory. (This is the one with the wp-admin, wp-includes, and wp-content folders.)

2. Go to the Ubuntu terminal and type:
sudo chown -v :www-data "/enterYourFilePathHere/.htaccess"
You should see a line printed saying that the (group) file ownership has been changed to www-data (Apache2).

3. Give Apache2 write access to the file:
sudo chmod -v 664 "/enterYourFilePathHere/.htaccess"
You should see a line printed saying that the mode of the file has been retained.

4. Next, we have to allow WordPress to write to the .htaccess file by enabling mod_write in the Apache2 server. Type the following in the terminal:
sudo a2enmod rewrite
You should see a line printed saying that it is enabling mod rewrite and reminding you to restart the web server

5. So let's do that. Restart the web server, Apache2, for the changes to take effect by typing:
sudo /etc/init.d/apache2 restart
We are all done with the command line prompt; you can close the command line window now.

5. Go into your WordPress admin panel (i.e. http://yourDomain/wp-admin). Go to the Settings --> Permalinks and select the permalink format of your choice. Hit the "Save Changes" button.

6. DONE! Go to your site and check any page (other than your homepage) to ascertain that everything is working as expected.

Hope this helps someone. Leave me a comment below.

It allows php to change the .htaccess and then the wordpress admin resets it.

If it's not working probably would do when you change the permalink to index.php/%postname%/. But it won't be pretty. So…

You will need to go to /etc/apache2/ and change all the directories to…

<Directory var/www/>
Options FollowSymLinks
AllowOverride All
</Directory>

If it is not working, my change are these:

<Directory />
        Options FollowSymLinks
        AllowOverride All
</Directory>

<Directory /usr/share>
        AllowOverride None
        Require all granted
</Directory>
<Directory /var/www/>
        Options FollowSymLinks
        AllowOverride All
</Directory>

#<Directory /srv/>
#       Options Indexes FollowSymLinks
#       AllowOverride None
#       Require all granted
#</Directory>

It's ultra-important to enable mod rewrite: a2enmod rewrite

1. Before of this install the plugin (you can do it on the admin panel) backupwordpress.
   • http://downloads.wordpress.org/plugin/backupwordpress.3.6.0.zip
2. Make and download a backup file. This file must contain files and database.
3. Format server
4. Install apache, php and Mysql. Ensure
5. Go to /var/www/html
6. Download with wget the last Wordpress.
7. Unzip the wordpress file.
8. Upload the previous backup file.
9. Unzip the backup file.
10. Change in the database file (.sql) the beginning adding: the next lines (if database is called blog):
    1. CREATE DATABASE blog;
    2. USE blog;
11. If database has a different password than the previous one you should change wp-config.php.
12. Execute the command: mysql -u <user> -p < db_backup.dump
13. Go to /var/www and execute:
    1. chown -R www-data html
    2. chgrp -R www-data html

It's possible to find in your /var/log/apache2/access.log a lot of lines like this: 111.222.333.444:80 555.666.777.888 - - [01/Jan/2016:16:33:50 -0500] “POST /xmlrpc.php HTTP/1.0” 200 674 “-” “Mozilla/4.0 (compatible: MSIE 7.0; Windows NT 6.0)”

<files xmlrpc.php>
      order allow,deny
      deny from all
    </files>

Si mueves un site a otra url puedes hacer varias cosas, en el wp-config.php. La mejor opción sea poner el RELOCATE, acceder y el mismo wordpress habrá arreglado las rutas.

define('RELOCATE',true); 

define('WP_HOME','https://2017.foropoliamor.org');
define('WP_SITEURL','https://2017.foropoliamor.org');

Para actualizar las urls utiliza: Velvet Blues Update URLs plugin, que se ubicará en herramientas.
