perl远程执行多台服务器shell命令

更新时间:2022-09-13 13:29:43

  在生成环境中通常运维需要执行非常多的重复命令,一台可能还好 多台就杯具了。尤其有时候要批量去更新多台服务器的文件,或者是删除。
   一个好运维都是懒惰的,所以自己写了个perl脚本可以远程去执行shell命令,很灵活。2个配置文件,一个管理服务器信息,一个放所需要执行的命令。
code:
#!/usr/bin/perl 
use strict; 
use Net::SSH::Expect; 
my @ssh_list; 
my $ssh_txt='ip_list.txt'; 
my $command_txt='command_txt.txt'; 
open FH,$ssh_txt; 
        while(<FH>){ 
        @ssh_list=split; 
        print "正在登陆".$ssh_list[0]."...\n"; 
        &ssh_conn("$ssh_list[0]","$ssh_list[1]","$ssh_list[2]","$ssh_list[3]"); 
        } 
        close    FH; 

sub    ssh_conn(){ 
                my($host,$port,$user,$pass) = @_; 
                my $ssh = Net::SSH::Expect->new( 
                                host        =>            $host, 
                                port        =>            $port, 
                                user        =>            $user, 
                                password                =>$pass, 
                                no_terminal         =>0, 
                                raw_pty =>1, 
                                timeout =>            3, 
                                ); 
                                                $ssh->debug(0); 
                                                $ssh->run_ssh() or die "SSH process coundn't start:$!"; 
                                                $ssh->waitfor( '\(yes\/no\)\?$', 1 ); #交互式修改密码,给予2秒的时间 
                                                $ssh->send("yes\n"); 
                                                $ssh->waitfor( 'password:\s*$/', 1); 
                                                $ssh->send("$ssh_list[3]"); 
                                                $ssh->send("su - root"); 
                                                $ssh->waitfor( 'password:\s*$/', 1); 
                                                $ssh->send("$ssh_list[4]"); 
                                                #$ssh->waitfor("#\s*",2); 
                                                open F1,$command_txt; 
                                                while(<F1>){ 


                                                my @command=split/\n/,$_; 
                                                print "$command[0]-->    "; 
                                                $ssh->exec("$command[0]"); 

                                                print "$ssh_list[0]命令执行完毕\n"; 


                                                } 
                                                close F1; 
                                                $ssh->close(); 
下面是2个文件内容。
[root@nagios script]# cat ip_list.txt 
192.168.2.101    22    mcshell     psswd    server1 
192.168.2.102    22    mcshell     psswd    server2 
192.168.2.103    22    mcshell     psswd    server3 
[root@nagios script]# cat command_txt.txt 
touch /home/mcshell/file1 
touch /home/mcshell/file2 
 
执行结果:
perl远程执行多台服务器shell命令
当然我这里为了测试方便,用了写的比较简单,大家也可以发挥想象,直接把复杂的shell或者perl密令直接放在command_txt.txt中。同样可以批量处理
