CentOS6.X: letsencrypt, cronjob and wrong "pip version"

772

I'm trying to write a script which will update the letsencrypt cert automatically via cronjob on up-to-date CentOS6.x.

To do that I wrote have following script:

#!/bin/sh

#
# get newest "Let's Encrypt" version
#
cd /opt/letsencrypt
git pull

# bug fix #201600233: update pip
echo "****************************************************************"
echo pip --version
pip --version
echo "****************************************************************"

pip install --upgrade pip

#
# update certs
#

# stop httpd
/etc/init.d/httpd stop

# renew certs
/opt/letsencrypt/letsencrypt-auto renew > /var/log/letsencrypt/renew.log 2>&1
LE_STATUS=$?

# start httpd
/etc/init.d/httpd start

# check "Let's Encrypt" result
if [ "$LE_STATUS" != 0 ]; then
    echo Automated renewal failed:
    cat /var/log/letsencrypt/renew.log
    exit 1
fi

Every time if I execute this script from commad line all is fine. The script is running without any errors. But every time when I start the script via cronjob I get the error

You are using pip version 8.0.3, however version 8.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Not sure why these occurres ... Are there any environment variables missing?

Here all of the output of the cronjob. Note also that the cronjob output says that the pip version is "8.1.2".

Already up-to-date.

At first: Thanks to "Jeremy Dover". Your comments was very helpful for me! :-)

After I have set the HOME environment variable to /root it works. Seems that letsencrypt takes the pip installation anywhere from /root/.local/share/letsencrypt/ (because I have installed letsencrypt as root user) and when the HOME variable was not correct set letsencrypt cannot found it...
