WordPress Tools is a set of tools that allow you to backup, restore, and upgrade WordPress sites. The tools are especially useful for upgrading very outdated sites and for scripting the backing up and upgrading of many sites.
WordPress Tools was built to make the Internet more secure. A huge number of websites on the Internet use WordPress, because it’s awesome, but a large portion of those sites do not run the latest version of WordPress which makes them susceptible to hacking. WordPress Tools can be used to get those sites up-to-date again, and that makes the whole Internet more secure.
The code has been used in production and has already upgraded over two million WordPress sites, but it has little real-world testing outside of Linux at this point so your mileage may vary if you have a different operating system. Stay tuned as we add support for more platforms, and please contribute if you feel like it.
The command-line program also has a lot of options for managing server load, so you can upgrade your sites without killing your server.
There are several ways to install WordPress Tools to your system.
The easiest way to install WordPress Tools is using cpanm. If you have a local perl (plenv, perlbrew, etc.), you can just do:
to install the
wp-tools executable and its dependencies. The executable will be installed to your perl’s bin path,
If you’re installing to your system perl, you can do:
cpanm --sudo App::WordPressTools
to install the
wp-tools executable to a system directory, like
/usr/local/bin/wp-tools (depending on your perl).
If you want to handle the Perl dependencies yourself and just want the
wp-tools executable, you can do:
curl -OL https://raw.githubusercontent.com/bluehost/wp-tools/solo/wp-tools chmod +x wp-tools
to download the
wp-tools executable to your current directory.
If you’re a developer and want to hack on the source, clone the repository and pull the dependencies:
git clone https://github.com/bluehost/wp-tools.git cd wp-tools cpanm Dist::Zilla dzil authordeps --missing | cpanm dzil listdeps --author --develop --missing | cpanm
WordPress Tools requires these other programs and libraries in order to do its work. You probably have most of these on your system already, and the cpanm method of installing wp-tools will handle the Perl module dependencies for you.
- GNU Coreutils
- GNU Tar
- mysql (MySQL server client)
- Various Perl modules (see the distributed
cpanfilefile for a list)
Show usage information and exit.
If there are any resource limits in effect, ignore them and do the command anyway.
Delete the oldest backups, keeping the number provided (default: 5).
Refuse to execute if the maximum number of defunct processes on the system exceeds this number (default: 100).
Refuse to execute if the load average exceeds this number (default: 200).
Refuse to back up a site if its uncompressed size on disk exceeds this number of bytes (default: 5368709120).
Do not allow more than this number of concurrent system-wide executions of the script (default: 50).
Refuse to execute if free memory has dropped below this number of bytes (default: 1048576).
wp-cliprogram has a different name than
wpor is not in your
$PATH, you can specify the command to be used to call wp-cli.
If you run wp-tools as a root user, it will drop permissions to the specified user and
chdirto their home directory.
The upgrade command will upgrade your WordPress core, themes, and plugins to the latest version available. It takes a full backup prior to the update. After the update, wp-tools will do a quick check to try to determine that nothing broke on your site. If any failures are detected, wp-tools will automatically restore to the backup taken prior to update.
The backup command will create a full backup, including database, of your WordPress installation as long as it is under the --max-size limit (pre-compression).
The restore command will restore a WordPress installation from a backup taken using the backup command.
# upgrade a site wp-tools upgrade --path=public_html/myblog \ --backupdir=myblog_backups # upgrade only plugins and themes wp-tools upgrade --path=public_html/myblog \ --backupdir=myblog_backups \ --components=plugin,theme # backup a site wp-tools backup --path=public_html/mysite \ --backupdir=backups/mysite # restore a site to a previous state wp-tools restore --backupfile=backups/mysite/wp_backup1428524082.tar.gz
Currently, wp-tools tries very hard to run with your
$HOME as the current working directory. It will
before executing its command, and it does NOT translate relative paths. This means that if you run wp-tools from
outside of your home directory with a relative path, your paths won’t be found. This is a temporary limitation that will
be fixed soon.
