Editing Wiki.tetrain.com Runbook (section)

=== 8.2 Add <code><nowiki>ServerAlias</nowiki></code> to both vhosts (only needed if 8.1 hit the ambiguity error) ===

Back up first:

<pre>
<nowiki>
cp /etc/httpd/conf.d/wiki.conf /etc/httpd/conf.d/wiki.conf.bak.$(date +%s)
cp /etc/httpd/conf.d/wiki-le-ssl.conf /etc/httpd/conf.d/wiki-le-ssl.conf.bak.$(date +%s)
</nowiki>
</pre>

Add <code><nowiki>ServerAlias wiki.tetrain.com</nowiki></code> right after each <code><nowiki>ServerName wiki-new.tetrain.com</nowiki></code> line, in both <code><nowiki>/etc/httpd/conf.d/wiki.conf</nowiki></code> (port 80) and <code><nowiki>/etc/httpd/conf.d/wiki-le-ssl.conf</nowiki></code> (port 443):

<pre>
<nowiki>
sed -i '/ServerName wiki-new.tetrain.com/a\    ServerAlias wiki.tetrain.com' /etc/httpd/conf.d/wiki.conf
sed -i '/ServerName wiki-new.tetrain.com/a\    ServerAlias wiki.tetrain.com' /etc/httpd/conf.d/wiki-le-ssl.conf
</nowiki>
</pre>

Broaden the HTTP→HTTPS redirect in <code><nowiki>wiki.conf</nowiki></code> to match either hostname:

<pre>
<nowiki>
sed -i 's/RewriteCond %{SERVER_NAME} =wiki-new.tetrain.com$/RewriteCond %{SERVER_NAME} =wiki-new.tetrain.com [OR]\nRewriteCond %{SERVER_NAME} =wiki.tetrain.com/' /etc/httpd/conf.d/wiki.conf
</nowiki>
</pre>

Resulting <code><nowiki>wiki.conf</nowiki></code> (port 80), confirmed live:

<pre>
<nowiki>

    ServerAlias wiki.tetrain.com
