改进我的备份 bash 脚本

发布于 2024-10-14 12:16:55 字数 589 浏览 5 评论 0原文

你好我将日志文件保存在 /opt/project/logs/ 下，并且我想每天通过压缩将它们复制到 /opt/bkp。

为此，我写了这个并且运行良好：

#!/bin/bash

getdate(){
  date --date="$1 days ago" "+%Y_%m_%d"
}

rm -rf "/opt/bkp/logs/myapp_log_"$(getdate 365).gz ;
/bin/cat /opt/project/logs/myapp.log | gzip > /opt/bkp/logs/myapp_log_`date +%Y_%m_%d`.gz ;
echo "" > /opt/project/logs/myapp.log ;

但是它不是功能性的或通用的，我将有几个应用程序用它们的名称保存文件，即在同一个 /opt 下的 app1.log app2.log /project/logs/ 文件夹。如何将其作为一个“函数”，其中脚本读取 /opt/project/logs/ 目录下的每个文件并备份以 .log 扩展名结尾的每个文件？

Hello
I keep my log files under /opt/project/logs/ and I want to daily copy these to /opt/bkp by compressing them.

For this I have written this and works well:

#!/bin/bash

getdate(){
  date --date="$1 days ago" "+%Y_%m_%d"
}

rm -rf "/opt/bkp/logs/myapp_log_"$(getdate 365).gz ;
/bin/cat /opt/project/logs/myapp.log | gzip > /opt/bkp/logs/myapp_log_`date +%Y_%m_%d`.gz ;
echo "" > /opt/project/logs/myapp.log ;

However it is not functional or general, I will have several applications saving files with their names ie app1.log app2.log under the same /opt/project/logs/ folder. How can I make this as a "function" where script reads each file under /opt/project/logs/ directory and taking backup of each file ends with .log extension?

您可以使用发行版附带的 logrotate(8) 工具。 :) 联机帮助页有一个看起来接近您需要的示例：

  /var/log/news/* {
       monthly
       rotate 2
       olddir /var/log/news/old
       missingok
       postrotate
           kill -HUP `cat /var/run/inn.pid`
       endscript
       nocompress
   }

好吧，不是 monthly 位，或重新启动 inn :) 但我希望您明白您可以轻松地将新的配置文件添加到 /etc/logrotate.d/ 中，而不必再担心它。 :)

You could use the logrotate(8) tool that came with your distro. :) The manpage has an example that looks close to your need:

  /var/log/news/* {
       monthly
       rotate 2
       olddir /var/log/news/old
       missingok
       postrotate
           kill -HUP `cat /var/run/inn.pid`
       endscript
       nocompress
   }

Well, not the monthly bit, or restarting inn :) but I hope you get the idea that you could easily add a new config file to /etc/logrotate.d/ and not worry about it again. :)

您是否考虑过使用“logrotate”？它会为你压缩和修剪日志，可选择踢出需要踢出的进程来关闭日志文件、泡茶等等。这可能是你的 Linux 机器用来进行日志管理的。

man logrotate

了解更多。按照您的方式，当您获得所需的功能时，您将已经编写了 logrotate :)

我也建议使用 logrotate，但无法抗拒编写此脚本:)

proc_logs() {
  for log in /opt/project/logs/*.log; do
    cat "$log" | gzip > ${log%/*}/$(basename "$log" ".log")_`date +%Y_%m_%d`.gz;
    touch "$log";
  done
}

I'd suggest using logrotate too, but can't resist writing this script :)

proc_logs() {
  for log in /opt/project/logs/*.log; do
    cat "$log" | gzip > ${log%/*}/$(basename "$log" ".log")_`date +%Y_%m_%d`.gz;
    touch "$log";
  done
}
