Wordpress: Bash Install Script -- Downloads latest WP version, updates wp-config with user supplied DB name, username and password, creates and CHMOD's uploads dir, copies all the files into the root dir you run the script from, then deletes itself!

Add this to your ~/.bashrc
alias wpinstall="curl -L -o 'wp.sh' https://gist.githubusercontent.com/bgallagh3r/2853221/raw/f3e2f2fa3048bbeb6d35799af068965bc5fd9b26/wp.sh && bash wp.sh" then source ~/.bashrc Go into a dir you want to install WP in and just type wpinstall It's that easy!

Update:
I've updated the URL to the gist in this comment, WP changed the latest.tar.gz to use HTTPS (finally) as such trying to grab a copy from http::// broke the script

Update: July 8 2015
I've modified the script to add the salts automatically now thanks to @emirpprime's fork.
the new command should be alias wpinstall="curl -L -o 'wp.sh' https://gist.githubusercontent.com/bgallagh3r/2853221/raw/eb5070c1a4f06dc106847f2e53f1b207f8ec7cad/wp.sh && bash wp.sh"

Note that my script does NOT create the MySQL database for you as I currently use WHM/cPanel on our server to manage databases. If you want that functionality please use @emirpprime's fork here: https://gist.github.com/emirpprime/37ef1f355ec5a7ecbb8f.

hi,

i would like to use your bash shell script above, please, if that would be o.k., to run a wordpress install during a Vagrant/PuPHPet script of installing a VM on an AWS/EC2 server?

however, i do have a question, and please pardon my shell script ignorance here — i all ready know the db name, user name & password, have that all set-up, and Vagrant/PuPHPet will install the correct versions of PHP & MySQL for me. so i would like to just have the db, user name & and password in the script without any of the echo & read requests, and just have it do the install. so to do that, would i, instead of running...

...
echo "Database Name: "
read -e dbname
...

...etc., would i do it as variables like this —

...
$dbname = my_mysql_wordpress_db_name
...

...etc.? would that be how to do it?

or would i just delete all the echo & read stuff and put it somewhere in these statements —

#set database details with perl find and replace
perl -pi -e "s/database_name_here/[my_mysql_wordpress_db_name]/g" wp-config.php
perl -pi -e "s/username_here/[my_mysql_wordpress_db_user]/g" wp-config.php
perl -pi -e "s/password_here/[my_mysql_wordpress_db_password]/g" wp-config.php

if you could please advise on this, i would appreciate it. thank you in advance.

best,

@faddah I have no issue with you using this, as this is a script I found and altered to suit my needs.

@faddah sorry I didn't see your comment until now... weird I wasn't notified, but you were correct in doing it the last way by just replacing the "s/database_name/" lines with the actual user/password info. I don't really recommend it, it would likely be better to use an env variable or something instead but to each their own.

Hi are you able to create the sql database in this script as well ?
Thanks and congrats works very nice.

@bgallaghr3 - really useful gist, thanks!

@brunogui81 - that's exactly what I wanted in too so added it in my fork https://gist.github.com/emirpprime/37ef1f355ec5a7ecbb8f
You'll probably need to modify it for your use (and that wasn't the only change), but it should get you going.

This is a fantastic script. One oddity I've noticed:

It seems like the password field being written to wp-config.php is stripping out meta characters. So if I enter a password that looks like: wordpr355u$3r, the dollar sign and the character following it are stripped out becoming:

wordpr355ur

I've tried something like:

perl -pi -e "s/password_here/\\Q${dbpass}/g" wp-config.php

But that doesn't solve the issue, and my Perl isn't very good. Any thoughts?

I've been looking for such.. need to try it out

This script builds a VM: https://github.com/enoch85/wordpress-vm

Here is another version with clear installation from scratch.
If you have just clean server on Debian or Ubuntu - than this script will be useful for you :)
It helps to create user, group, install and configure Apache, MySQL, firewall, latest version of WordPress, some popular plugins and some other stuff.
https://github.com/sm0k3net/Useful-Scripts/blob/master/wordpress.sh

Hello, first I want to thanks for this script!
However, how to deal with password that contain special character?
e.g. when I type "P@$$word" at prompt, then it generate wp-config that contain:

/** MySQL database password */
define('DB_PASSWORD', 'p');

Great script thank you

Mint script, thanks.

Hi, another updated version. This one where can create the database and asks to use if it already exists.
https://gist.github.com/FeChagas/54b0cdf354b197dc8e417357d7687e8b

Another installer for Shell perspective: https://github.com/cconversion/wp-installer
Inspired by, not forked from, this here @bgallagh3r gist.

Here is High Traffic wordpress server configuration bash script
https://github.com/bajpangosh/High-Traffic-wordpress-server-configuration

Wow, this Gist is still at the top of Google for "WordPress installer script" after 5+ years...

A simpler way to generate the salts via OpenSSL (albeit slightly less secure, but less chance of conflict due to symbols):

sed -i "s/put your unique phrase here/$(openssl rand -hex 48)/g"

Please check out SlickStack (any feedback appreciated):

Great gist :). Inspired me to fork it and modify it by adding support for wp-cli

Hi,
I am new to Perl and I want to change the table prefix as well.
Can you please tell me, how can I change the table prefix?

Worked like a charm and quickest installation of WordPress I have achieved so far. Thanks

Simple, direct, and reliable

Great work. Thanks!

I took this a step further by allowing it to configure my nginx server block. See here:

https://gitlab.com/snippets/1988869

I wish there was something this simple for bind9 as well haha

Add this to your ~/.bashrc
alias wpinstall="curl -L -o 'wp.sh' https://gist.githubusercontent.com/bgallagh3r/2853221/raw/f3e2f2fa3048bbeb6d35799af068965bc5fd9b26/wp.sh && bash wp.sh" then source ~/.bashrc Go into a dir you want to install WP in and just type wpinstall It's that easy!

I think the link above for @emirpprime's fork is broken. A google search suggest that he has changed his github handle?
I think the new link is: https://gist.github.com/phlbnks/37ef1f355ec5a7ecbb8f

Hi pal! I think you must add a database host URL to the script. Usually, it's localhost in wp-config.php and not work for me.
