我创建了一个脚本，每天晚上在我的Linux服务器上运行，它使用mysqldump将我的每个MySQL数据库备份到.sql文件，并将它们打包成一个压缩的.tar文件。我想完成的下一步是通过电子邮件将tar文件发送到远程电子邮件服务器以确保安全。我已经能够通过管道备份文本文件到mailx发送原始脚本正文的电子邮件，就像这样:
$ cat mysqldbbackup.sql | mailx backup@email.example
Cat回显备份文件的文本，该文本通过管道输入mailx程序，并将收件人的电子邮件地址作为参数传递。
虽然这实现了我所需要的，我认为它可以更好的一步，有任何方法，使用shell脚本或其他方式，将压缩的.tar文件作为附件发送到外发电子邮件消息?这将避免处理包含标题数据和经常有换行问题等非常长的电子邮件。

只是补充我的2分，我会写我自己的PHP脚本:

在该页上的示例中，有很多方法来处理附件。

我曾经在Solaris上为ksh写过这个函数(使用Perl进行base64编码):
# usage: email_attachment to cc subject body attachment_filename
email_attachment() {
to="$1"
cc="$2"
subject="$3"
body="$4"
filename="${5:-''}"
boundary="_====_blah_====_$(date +%Y%m%d%H%M%S)_====_"
{
print -- "To: $to"
print -- "Cc: $cc"
print -- "Subject: $subject"
print -- "Content-Type: multipart/mixed; boundary=\"$boundary\""
print -- "Mime-Version: 1.0"
print -- ""
print -- "This is a multi-part message in MIME format."
print -- ""
print -- "--$boundary"
print -- "Content-Type: text/plain; charset=ISO-8859-1"
print -- ""
print -- "$body"
print -- ""
if [[ -n "$filename" && -f "$filename" && -r "$filename" ]]; then
print -- "--$boundary"
print -- "Content-Transfer-Encoding: base64"
print -- "Content-Type: application/octet-stream; name=$filename"
print -- "Content-Disposition: attachment; filename=$filename"
print -- ""
print -- "$(perl -MMIME::Base64 -e 'open F, shift; @lines=<F>; close F; print MIME::Base64::encode(join(q{}, @lines))' $filename)"
print -- ""
fi
print -- "--${boundary}--"
} | /usr/lib/sendmail -oi -t
}
echo -e 'Hi, \n These are contents of my mail. \n Thanks' | mailx -s 'This is my email subject' -a /path/to/attachment_file.log -b bcc.email@example.com -c cc.email@example.com -r from.email@example.com to.email1@example.com to.email2@example.com to.email3@example.com
Metamail有metasend工具
metasend -f mysqlbackup.sql.gz -t backup@email.com -s Backup -m application/x-gzip -b
使用mailx命令
echo "Message Body Here" | mailx -s "Subject Here" -a file_name user@example.com
使用sendmail
#!/bin/ksh
fileToAttach=data.txt
`(echo "To: user@company.example"
echo "Cc: user@company.example"
echo "From: Application"
echo "Subject: your subject"
echo your body
uuencode $fileToAttach $fileToAttach
)| eval /usr/sbin/sendmail -t `;
这是我在CentOS中处理一个大日志文件的方式:
#!/bin/sh
MAIL_CMD="$(which mail)"
WHOAMI="$(whoami)"
HOSTNAME="$(hostname)"
EMAIL"your@email.address"
LOGDIR="/var/log/aide"
LOGNAME="$(basename "$0")_$(date "+%Y%m%d_%H%M")"
if cd ${LOGDIR}; then
/bin/tar -zcvf "${LOGDIR}/${LOGNAME}".tgz "${LOGDIR}/${LOGNAME}.log" > /dev/null 2>&1
if [ -n "${MAIL_CMD}" ]; then
# This works too. The message content will be taken from text file below
# echo 'Hello!' >/root/scripts/audit_check.sh.txt
# echo "Attachment" | ${MAIL_CMD} -s "${HOSTNAME} Aide report" -q /root/scripts/audit_check.sh.txt -a ${LOGNAME}.tgz -S from=${WHOAMI}@${HOSTNAME} ${EMAIL}
echo "Attachment" | ${MAIL_CMD} -s "${HOSTNAME} Aide report" -a "${LOGNAME}.tgz" -S from="${WHOAMI}@${HOSTNAME}" "${EMAIL}"
/bin/rm "${LOGDIR}/${LOGNAME}.log"
fi
