如何使用 crontab、.netrc 和 git push？

  • 772

我正在将各种服务器的备份自动化到一个中心点，然后将这些配置更改推送到一个 git repo 中，这样我就可以随着时间的推移跟踪任何更改。其余脚本运行良好，我可以通过网络将文件复制/同步到中心点。最后一个脚本是获取要放入/更新存储库的配置文件。脚本如下：

#!/bin/bash
clear

SERVERNAME="betty"
SCRIPTDIR="/home/jon"
GITROOT="/tmp/git"
TEMPROOT="/tmp/backups"
BACKUPROOTDIR="/mnt/backups"

echo "  - running as user: $UID"

echo "backingup git config on $SERVERNAME"
echo ""

# check to see if root backup folder exists, otherwise create it.
if [ -d $GITROOT ]; then
    rm -rf $GITROOT
fi
mkdir $GITROOT

cd $GITROOT

echo "  - testing if home is where I think it should be!"
echo $HOME
echo "  - testing if it can see netrc"
tail $HOME/.netrc


git clone http://192.168.10.97:8000/repositories/HOH-config-backups.git
cd HOH-config-backups

echo "  - copy Configuration Folders across"
cp -r $BACKUPROOTDIR/Configuration/* $GITROOT/HOH-config-backups/
cp -r $BACKUPROOTDIR/scripts $GITROOT/HOH-config-backups/

git add .
git commit -a -m "committing any new configuration changes!"
git push origin master

echo ""
echo "Git repo updated"

echo ""
echo "  - backing up this script"
FIREWIGSCRIPTLOC="$BACKUPROOTDIR/scripts/$SERVERNAME"

if [ ! -d $FIREWIGSCRIPTLOC ]; then
    mkdir $FIREWIGSCRIPTLOC
fi

cp /home/jon/gitConfig.sh  $FIREWIGSCRIPTLOC

git repo 位于使用 Apache 和 HTTP-backend.exe（智能 HTTP 协议）的网络中的另一台机器上。如果我以“jon”身份运行这个脚本，它就可以工作。如果我在 crontab 中运行它，它会失败。git 使用 /home/jon/.netrc 文件进行身份验证：

machine 192.168.10.97
login gitconfig
password 1234579

来自 crontab 的日志是：

TERM environment variable not set.
  - running as user: 1000
backingup git config on betty

  - testing if home is where I think it should be!
/home/jon
  - testing if it can see netrc
machine 192.168.10.97
login gitconfig

我的 crontab 是：

# m h  dom mon dow   command
04 * * * * /home/jon/gitConfig.sh > /tmp/gitconfig.log 2>&1

我通过以下方式打开它：

$crontab -e

即不是根。

了解用户标识：

jon@betty:~$ id
uid=1000(jon) gid=1000(jon)  groups=4(adm),20(dialout),24(cdrom),46(plugdev),109(sambashare),114(lpadmin),115(admin),1000(jon)

这是我的 $HOME/.gitconfig 文件：

[user]
    name = Jon Hawkins
    email = [email protected]
crontab git

  1. 我认为问题出在您的 .gitconfig 中。你在里面设置了用户名吗？此外，如果您要备份到远程计算机，我强烈建议您使用 SSH 来代替。
