从PHP exec（）函数运行Hugo

Question

I'm attempting to setup a continuous deployment script for Hugo on a LAMP stack server, and the last snag I'm running into is getting Hugo to run.

The Background

I have Hugo and PHP installed on a VPS, and for my app, two directories:

1. public , where my actual site lives.
2. hugo , where my entire Hugo setup gets pulled into from GitHub.

I'm using a GitHub webhook to ping my deploy.php script when I merge into the master branch. Here's the relevant part of that script:

// 1. Pull the latest build from GitHub
exec('cd /path/to/hugo && git fetch --all && git reset --hard origin/master');

// 2. Run Hugo to compile any new posts and pages into HTML
exec('cd /path/to/hugo && hugo');

// 3. Copy the files in the /public directory from Hugo into the /public app directory
exec('cd /path/to/hugo && cp -r /path/to/hugo/public/. public');

What's happening

Items 1 and 3 run. Item 2 does not.

More clearly stated: the latest build pulls from GitHub, and any files I've built ahead of time are copied from the Hugo build into the /public directory.

I cannot get hugo to run via exec() , though, and I'm not entirely sure why.

If I SSH into the server in a terminal window, cd into the /path/to/hugo directory, and run hugo there, everything compiles as expected, which eliminates things like, "Maybe Hugo is installed wrong" or "Maybe Hugo isn't accessible in that directory".

So... what am I missing? Thanks in advance!

Answer 1

Check if this is a path issue, meaning by default, a bash session won't execute a program just because you are in the right folder: you have to specify its path (in your case: the current folder)

That means: replace && hugo with && ./hugo

Or, as the OP Chris Ferdinandi did ( comments ), you can use an absolute path:

I ssh-ed into the server and ran which hugo to get the appropriate path, and replaced && hugo with that.
