Step 1: Enable Apache status and lock it down: Make sure mod_status is being loaded:
|
|
shell> grep -Rn mod_status /etc/httpd/* /etc/httpd/conf.modules.d/00-base.conf:58:LoadModule status_module modules/mod_status.so |
Add support for the call just under the first DocumentRoot statement:
|
|
shell> vim /etc/httpd/conf/httpd.conf <Location /server-status> SetHandler server-status Require ip 127.0.0.1 Require ip ::1 Require ip {Your_IP_Here} </Location> |
Step 2. Prepare your environment:
|
|
shell> cpan YAML HTML::TableExtract |
Step 3: Create and run the status script: (See the astat contents at the bottom)
|
|
shell> vim /root/astat shell> chmod 755 /root/astat shell> vi ~/.bashrc ADD: alias ipw='while true; do sleep 5; /root/astat; done' shell> ipw 1.2.3.4|yourdomain.com:443|POST /wp-cron.php?doing_wp_cron=1563901063.57946491241455078125| |

This post does not cover configuring letsencrypt or ssl/https. First, make sure your LetsEncrypt configuration points to the actual WordPress document root directory cat /etc/letsencrypt/renewal/www.yourdomain.com.conf
|
|
... [[webroot_map]] yourdomain.com = /volumes/data/www/yourdomain.com/prod/wordpress www.yourdomain.com = /volumes/data/www/yourdomain.com/prod/wordpress |
Second, use the new macro language feature in Apache 2.4 to configure an https redirect macro which does NOT redirect to https for anything in the .well-known subdirectory. This […]

Apache 2.4 changed the security configuration directives a bit. Here is an example using basic auth:
|
|
<Directory "/path/to/your/wordpress"> AllowOverride All Options +FollowSymLinks +ExecCGI -Indexes Order allow,deny Allow from all <RequireAll> AuthType Basic AuthName "Protected Resource" AuthUserFile /path/to/your/.htpasswd Require valid-user </RequireAll> </Directory> |
What tripped me up for a while was that I still had the Require all granted directive inside the container, and that needed to be removed for the auth to work.

If you get this error when starting Apache or via apachectl configtest: [warn] _default_ VirtualHost overlap on port 443, the first has precedence then you must add: NameVirtualHost *:443 to /etc/httpd/conf/httpd.conf, then restart Apache

If you need to use wget to obtain the contents of a web page, but that page has either Basic or Digest Authentication enabled, use the following syntax to gain access: wget –http-user=yourUserNameHere –http-password=yourSecretPasswordHere http://example.org/desired/path/ ~or~ wget http://yourUserNameHere:yourSecretPasswordHere@yourSite.com/desired/path/

If when trying to use SVG as an image <img src=”image.svg”> or as a CSS background-image, the browser doesn’t display it, your web host is probably serving the SVG with the wrong content-type. Add this to your web server config or .htaccess file: AddType image/svg+xml .svg .svgz
