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!

Hi, another updated version. This one where can create the database and asks to use if it already exists.

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!

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.

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.
