写的一个perl脚本，用于发送远程MySQL命令
想写一些简化管理操作的脚本，下面是基础脚本之一。
对于一个从来没使用过perl脚本的我来说还是有些难度的，直接上代码。
此脚本用于发送远程MySQL命令并且接收结果，功能比较简单，后面会渐渐完善。
#!/usr/bin/perl
use Getopt::Long;
use DBI;
Getopt::Long::GetOptions(
'host|h=s' => \$host,
'user|u=s' => \$user,
'password|pw=s' => \$password,
'port|p=s' => \$port,
'command|c=s' => \$command,
'groupfile|f=s' => \$groupfile,
'help' => \$help
);
#print help info
my $printh=q{
usage :
mysqlcon -h 192.168.0.33 -u root -pw 'xiaojun' -p 3306 -c 'show global status'
or
mysqlcon -g 2.txt -c 'select user();'
cat 2.txt:
192.168.0.33 root xiaojun 3306
192.168.0.34 root xiaojun 3306
options:
-h database server *
-u account name *
-pw password for account *
-p port for mysqld *
-c command to execute *
-help print help
};
=pod
if(!defined($host)){
print "page flag set to $page "
}
if(defined($user)){
print "user flag set to $user\n ";
}
if(defined($password)){
print "onoff flag set to $password \n";
}
if(defined($command)){
print "help flag set to $command \n";
}
if(defined($help)){
print $printh
}
=cut
sub execute_sql{
my $dsn = "DBI:mysql:database=mysql;host=$_[0]:$_[1]";
my ($dbh,$sth,@ary);
$dbh = DBI->connect($dsn,$_[2],$_[3],{'RaiseError' => 1});
$sth = $dbh->prepare("$_[4]");
$sth->execute();
while(@ary = $sth->fetchrow_array()){
print join("\t",@ary),"\n";
}
$sth->finish;
$dbh->disconnect;
}
#&execute_sql($host,$port,$user,$password,$command) ;
unless (!defined($help)) { die "$printh" };
if(defined($groupfile)){
unless (defined($command)) { die "Wrong usage : No command input .\n $printh" };
open(IN,$groupfile);
while($line=<IN>){
my @args=split /\s/,$line;
print "host:@args[0]\ncommand:$command\n******BEGIN\n";
&execute_sql(@args[0],@args[3],@args[1],@args[2],$command) ;
print "******END \n\n\n*****************************************************\n\n\n";
}
}else{
unless (defined($host)) { die "Wrong usage : No host input .\n $printh" };
unless (defined($user)) { die "Wrong usage : No account input .\n $printh" };
unless (defined($password)) { die "Wrong usage : No password input .\n $printh" };
unless (defined($port)) { die "Wrong usage : No port number input .\n $printh" };
unless (defined($command)) { die "Wrong usage : No command input .\n $printh" };
&execute_sql($host,$port,$user,$password,$command) ;
}
