WordPress Multisites

How to use Wordpress (multi-site)

! There is users (and administrators) for the network administration of the farm and there is users (and admin) per blog wp !

If a user is created on the network level, than she/he has to be added as a user of a particular blog to be able to write in it

For now, a new template or plug-in should be added by hand (threw ssh access on the server, see below)

For users of the WP farm here a good page with security recommendations for users of WP farms, need to be adapted to AS

Configuration an tuning

Configure the upload limit for all the blogs in https://zoiahorn.anarchaserver.org/wp-admin/network/settings.php

Max upload file size 1000000 k 

Disable comments on new blog if not needed

Classic editor has been set up by default on all blogs (bug in the new one)

nano /etc/apache2/sites-available/zoiahorn.conf

<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        ServerName zoiahorn.anarchaserver.org


        ErrorLog ${APACHE_LOG_DIR}/zoiahorn-error.log

Troubleshooting

Permalinks

Not possible to change the way Wordpress produce the permalinks: for each site https://zoiahorn.anarchaserver.org/wp-admin/options-permalink.php

Only "Plain" system work, else the articles give a 404 when linked, may come from .htaccess or FollowSymlink in apache ? > I think the problem was coming from the vhost syntax about followsymlink, it works now

Sending mail from wordpress

by default it is wordpress@anarchaserver.org the adress that send the mails from wordpress

Not usefull ? A trial to see if it improves things 25102019 : add a TXT record in gandi DNS record :

@	TXT	1800	"v=spf1 include:anarchaserver.org a mx ~all"

Or install sendmail !

apt install sendmail

To test if sending a mail work :

echo "Subject: sendmail test 5" | sendmail -v validemail@mail.org

If

050 504 5.5.2 <livingdata>: Helo command rejected: need fully-qualified hostname

There is the need to add the hostname in sendmail config :

nano /etc/mail/sendmail.mc

add line 40 :

define(`confDOMAIN_NAME', `zoiahorn.anarchaserver.org')dnl

then, to take the changes into account

sendmailconfig

the previous command should work (see in the spam folder)

To test via php :

php -a
mail ('you@example.com', "Test Postfix", "Test mail from postfix");
quit
