因為工作的關(guān)系,需要改用Perl語言進行編程,下面以CentOS7為例安裝Perl編程環(huán)境。
安裝Perl
一個命令基本上就搞定了,如果環(huán)境能夠聯(lián)網(wǎng)的話。
# yum install perl*
如果不能聯(lián)網(wǎng),可以下載最新的源碼包進行編譯安裝。
# 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
查看安裝成功的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)

編寫第一個Perl程序
創(chuàng)建Perl腳本;
# touch test.pl
編寫Hello World程序;
#!/usr/bin/perl
print "Hello World!\n"
執(zhí)行程序;
[root@controller ~]# perl test.pl
Hello World!
成功!
