Wikijs port bindings

It took me too long to figure this out, and the documentation wasn’t as clear as it should be. This is how the port bindings map out when using docker-compose with wikijs:

config.yml -> host = docker-compose.yml -> left side of : in the ports section of the wikijs image

config.yml -> ports = docker-compose.yml -> right side of : in the ports section of the wikijs image

Here’s an image to make it more clear.

Quick WP upgrading with WPCLI

This is the easiest way to upgrade WordPress. You’ll execute these commands on the server itself.

Requirements

  • ssh access to your server
  • wp-cli command installed (instructions for installing wp-cli at http://wp-cli.org/)

Install/Upgrade WP CLI

  • wp-cli should be upgraded each time a WordPress installation is upgraded.
wp cli update

Upgrade WP

Prep work

Change into the WP directory

cd /path/to/wordpress/installation/

Make a list of active plugins

wp plugin list --status=active --format=csv --fields=name | tail -n +2 > ../active-plugins.txt

Update all plugins

wp plugin update --all

Deactivate all of the plugins

wp plugin deactivate --all

Upgrade WordPress

wp core update

Reactivate all of the previously active plugins.

cat ../active-plugins.txt | xargs wp plugin activate

Grab all of the domain names in Apache host file

Quick script I whipped up today to grab all of the domain names on a server.

#!/bin/bash

if [ -e alldomains ]
then
  rm alldomains
fi

alldomains=( $(find /etc/httpd/conf.vhosts/ -name *.conf) )

for domain in ${alldomains[*]}
do
  cat $domain | egrep "ServerName|ServerAlias" | egrep -v "#" | sed -e 's|ServerName||' -e 's|ServerAlias||' -e 's|www.||' -e 's|:80||' | tr -s ' ' '\n' | tr -d ' ' | sed -e '/^\s*$/d' >> alldomains
done

sort alldomains | uniq | sort -o alldomains

 

This gets all of the domains from ServerName and ServerAlias lines, takes out all of the white space and empty lines, and creates a file with just a list of the unique domain names.

This accounts for subdomains that use ‘www’ or have port :80 on the end.

For instance, www.somedomain.com and somedomain.com are the same, so the script takes out the ‘www.’ which leaves to copies of somedomain.com, which it then deletes one of them in the final output to the file. The same for ‘:80’.
