CentOS6.X：letsencrypt、cronjob 和錯誤的“pip 版本”

  • June 3, 2016

我正在嘗試編寫一個腳本，該腳本將在最新的 CentOS6.x 上通過 cronjob 自動更新letsencrypt 證書。

為此，我編寫了以下腳本：

#!/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

每次如果我從命令行執行這個腳本一切都很好。該腳本正在執行，沒有任何錯誤。但是每次當我通過 cronjob 啟動腳本時，我都會收到錯誤消息

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.

不知道為什麼會發生這些……是否缺少任何環境變數？

這裡是 cronjob 的所有輸出。另請注意，cronjob 輸出表明 pip 版本為“8.1.2”。

Already up-to-date.

起初：感謝“傑里米·多佛”。你的評論對我很有幫助！:-)

在我將HOME環境變數設置為/root它之後。似乎letsencrypt可以從任何地方安裝pip /root/.local/share/letsencrypt/（因為我已經以root使用者身份安裝了letsencrypt）並且當HOME變數不正確設置時letsencrypt找不到它……
