问题 I can run a perl script "myperlscript.pl" from Terminal without any problems. However, if I try to run the same perl script from within RStudio, it gives me the following error: command <- "myperlscript.pl outputfile.txt" system2('perl', command) Can't locate Sort/Fields.pm in @INC (you may need to install the Sort::Fields module) (@INC contains: /Library/Perl/5.28/darwin-thread-multi-2level /Library/Perl/5.28 /Network/Library/Perl/5.28/darwin-thread-multi-2level /Network/Library/Perl/5.28

Nginx 域名跳转

域名跳转 　　就是实现URL的跳转和隐藏真实地址，基于Perl语言的正则表达式规范。平时帮助我们实现拟静态，拟目录，域名跳转，防止盗链等 。 域名跳转配置 1、多域名指定一个域名重定向 # 空格分割域名 server_name www.123.com www.456.com www.678 .com; # 判断如果访问域名不等于www.123.com，就指定到www.123.com if ($host != ' www.123.com ' ) { rewrite ^/(.*)$ http://www.123.com/$1 permanent; } 虚拟主机文件内 注：permanent == 301重定向 2、域名HTTPS跳转 server { listen 80 ; server_name www.域名.com; rewrite ^(.*) https://$server_name$1 permanent; } HTTPS域名跳转 来源： oschina 链接： https://my.oschina.net/u/4350253/blog/4224110

在 Ubuntu 中安装 Apache、MySQL、PHP（LAMP）套件

由 删除回忆录丶 提交于 2021-01-23 09:35:27
LAMP 套件是一种流行的开源 Web 开发平台，可用于运行和部署动态网站和基于 Web 的应用程序。通常，LAMP 套件由 Apache Web 服务器、MariaDB/MySQL 数据库、PHP/Python/Perl 程序设计（脚本）语言组成。 LAMP 是 L inux， M ariaDB/ M YSQL， P HP/ P ython/ P erl 的缩写。 本教程描述了如何在 Ubuntu 18.04 LTS 服务器中安装 Apache、MySQL、PHP（LAMP 套件）。 就本教程而言，我们将使用以下 Ubuntu 测试。 操作系统 ：Ubuntu 18.04.1 LTS Server Edition IP 地址 ：192.168.225.22/24 1. 安装 Apache Web 服务器 首先，利用下面命令更新 Ubuntu 服务器： $ sudo apt update $ sudo apt upgrade 然后，安装 Apache Web 服务器（命令如下）： $ sudo apt install apache2 检查 Apache Web 服务器是否已经运行： $ sudo systemctl status apache2 输出结果大概是这样的： ● apache2.service - The Apache HTTP Server Loaded: loaded

我竟然因为开放zookeeper服务而中了挖矿病毒？

由 瘦欲@ 提交于 2021-01-22 13:38:14
事情是这样的，我今天早上醒来手机上收到了来自腾讯云的通知，说我服务器中木马，于是我来到腾讯云控制台查看了一下，发现了5个病毒文件。 我的第一反应便是中挖矿病毒了，于是我顺便查看了一下服务器监控情况。果不其然，CPU直接跑满了。 于是我赶紧登陆了服务器， top 一下了解一下具体情况。 原来是这个名为kswapd0的程序登陆了我创建的zookeeper用户在疯狂的跑着我服务器的CPU。 于是我便上网搜了一下kswapd0，经过查证，这玩意是一个perl脚本，通过SSH爆破攻击目标系统，同时传播基于Perl的Shellbot和门罗币挖矿木马。 结果我便想到了，我本来用来玩转zookeeper而创建的zookeeper用户，账号密码都是zookeeper，而zookeeper客户端开启默认端口2181我也未进行修改。 我尝试登陆zookeeper用户，结果发现密码竟然不正确。好家伙，竟然还修改了我密码，于是我便通过root用户使用 passwd 命令重置了一下该用户密码。 接着，我使用 netstat -anltp|grep kswapd0 命令查看了一下kswapd0进程的对外端口，IP竟然来自荷兰。 因为我zookeeper服务端是一直开着的，也不难想象为什么会中病毒了。 病毒处理 杀死进程： 删除腾讯云控制台显示的木马程序所在的文件夹 将木马文件进一步隔离 可以看到

How can I create a random number between two numbers in Perl

由 吃可爱长大的小学妹 提交于 2021-01-21 06:47:43
问题 I've seen many other ways to do this in other programming languages... Though I havent found one in Perl yet... What I want to accomplish is to set two numbers: $minimum = 100; $maximum = 4000; Then to create a random integer between those two. (whole number) ($random_num) I've looked into this site: http://perlmeme.org/howtos/perlfunc/rand_function.html Which is a good resource, although does not do exactly that. 回答1: my $x = $minimum + int(rand($maximum - $minimum)); http://perldoc.perl.org
