因为工作的关系，需要改用Perl语言进行编程，下面以CentOS7为例安装Perl编程环境。

安装Perl

一个命令基本上就搞定了，如果环境能够联网的话。

# yum install perl*

如果不能联网，可以下载最新的源码包进行编译安装。

# wget http://www.cpan.org/src/5.0/perl-5.24.1.tar.gz
# tar -xzf perl-5.24.1.tar.gz 
# cd perl-5.24.1 
# ./Configure -des -Dprefix=$HOME/localperl 
# make 
# make test 
# make install

查看安装成功的Perl版本：

[root@controller ~]# perl -v

This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
(with 34 registered patches, see perl -V for more detail)

编写第一个Perl程序

创建Perl脚本；

# touch test.pl

编写Hello World程序；

#!/usr/bin/perl
print "Hello World!\n"

执行程序；

[root@controller ~]# perl test.pl 
Hello World!

成功！
