Linux下安装Perl Oracle模块

1、下载DBI和DBD
https://www.wendangku.net/doc/a116863192.html,/~timb/DBI-1.605/ DBI-1.605
在https://www.wendangku.net/doc/a116863192.html,/~pythian/DBD-Oracle-1.21/下载DBD-Oracle-1.21
2、查看perl是否安装
[oracle@olivenan ~]$ perl -v

[oracle@olivenan ~]
3、安装DBI，应该先安装DBI否则DBD无法安装成功
解压过程略
[root@olivenan DBI-1.605]# perl Makefile.PL
....
[root@olivenan DBI-1.605]# make
...
[root@olivenan DBI-1.605]# make install
...
4、安装DBD-Oracle
[root@olivenan ~]# tar -zxvf DBD-Oracle-1.21.tar.gz
我在root下进行安装出现错误如下：提示未设置环境变量ORACLE_HOME
[root@olivenan DBD-Oracle-1.21]# perl Makefile.PL
Using DBI 1.605 (for perl 5.008005 on i386-linux-thread-multi) installed in /usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/DBI/
Configuring DBD::Oracle for perl 5.008005 on linux (i386-linux-thread-multi)
Remember to actually *READ* the README file! Especially if you have any problems.
Trying to find an ORACLE_HOME
Your LD_LIBRARY_PATH env var is set to ''
The ORACLE_HOME environment variable is not set and I couldn't guess it.
It must be set to hold the path to an Oracle installation directory
on this machine (or a machine with a compatible architecture).
See the appropriate README file for your OS for more information.
ABORTED!

[root@olivenan DBD-Oracle-1.21]# export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
[root@olivenan DBD-Oracle-1.21]# perl Makefile.PL
...
[root@olivenan DBD-Oracle-1.21]# make
...
[root@olivenan DBD-Oracle-1.21]# make install
...
至此安装成功
5、验证结果
脚步如下：
db.pl ：
#!/usr/bin/perl -w
use DBI;

#$dbh = DBI->connect("dbi:Oracle:$dbname",$user,$passwd) or die "can't connect todat
abase ". DBI-errstr;
# Connect to target DB
my $dbh = DBI->connect("dbi:Oracle:orcl","test","test", {'RaiseError' => 1});
# Insert one row
my $rows = $dbh->do("INSERT INTO t (id) VALUES (1)");
#print "insert $rows rows\n";
# query
my $sth = $dbh->prepare("SELECT id FROM t");
$sth->execute;
while(my @ref = $sth->fetchrow_array ) {
print "$ref[0]\n";
}
$dbh->disconnect();
"db.pl" 25L, 501C written
在root下执行脚本出错
[root@olivenan ~]# perl db.pl
install_driver(Oracle) failed: Can't load '/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: libclntsh.so.10.1: cannot open shared object file

[root@olivenan ~]# chmod oracle:oinstall db.pl
[root@olivenan ~]# mv db.pl /home/oracle/
oracle用户下执行，成功
