利用Perl 脚本实现 MySQL 异机导入导出2013-10-30单位的开发同事需要将一个mysql 中的库导入到本地mysql中 所以为了减少手工操作，就写了下面的一个用perl 实现的 mysql 异机导入导出脚本：如下

#！/usr/bin/perl -w
#Author:andylhz
#Date:20120/08/29
#Purpose:Import database from other mysql db host to local.
my $db_host_local="localhost";
my $db_username_local="root";
my $db_password_local="password";
my $db_dbname_local="baby";
my $db_backupdir_local="/root/dbbackup/local";
if （-e $db_backupdir_local）{
print "The database backup dir is $db_backupdir_local ";
}else{
mkdir $db_backupdir_local;
}
my $db_time_local=`date +%y%m%d%H%M%S`;
#backup localhost databases
print "$db_dbname_local is backuping..... ";
system "/usr/local/mysql/bin/mysqldump -h $db_host_local -u$db_username_local -p$db_password_local --databases $db_dbname_local >$db_backupdir_local/$db_dbname_local$db_time_local";
if （ $？==0 ）{
print "Database $db_dbname_local is backup OK！ ";
}else{
print "Database $db_dbname_local is backup FALSE！ ";
exit ;
}
print "Compress the dump file ";
system "gzip $db_backupdir_local/$db_dbname_local$db_time_local";
if （ $？==0 ）{
print "Dump file is compress OK！ ";
}else{
print "Dump file is compress FALSE！ ";
exit;
}
