【Perl】Linux下安装perl的DBI和DBD模块
一、安装步骤
先安装DBI,再安装DBD
1.安装前置包
如果有，请忽略
yum install perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker
yum -y install perl-Digest-MD5
2.确定是否存在环境变量 $LD_LIBRARY_PATH,没有的话需要配置
[root@host-10-227-222-144 DBI-1.636]# $LD_LIBRARY_PATH
bash: /tycj/app/oracle_client/product/11.2.0/client_1/lib:/tycj/app/oracle_client/product/11.2.0/client_1/jdbc/lib: No such file or directory
配置参考：
ORACLE_BASE=/u01/app/oracle_client
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/client_1
LD_LIBRARY_PATH=${ORACLE_HOME}/lib:${ORACLE_HOME}/jdbc/lib
export PATH=$ORACLE_HOME/bin:$PATH
export LANG=en_US.UTF-8
#export LANG=C
export LD_LIBRARY_PATH
export TMOUT=6000
export ORACLE_BASE
export ORACLE_HOME
export ORACLE_SID=orcl
3.确认本机perl存在,没有的话,还需要安装perl
perl -version
[root@host]# perl -version
This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
(with 29 registered patches, see perl -V for more detail)

4.安装前要修改oracle_client/product/11.2.0/client_1/lib目录下两个软连接
cd /home/manager/oracle_client/product/11.2.0/client_1/lib
rm -rf libclntsh.so
rm -rf libclntsh.so.10.1
ln -s /home/manager/oracle_client/product/11.2.0/client_1/lib/libclntsh.so.11.1 /home/manager/oracle_client/product/11.2.0/client_1/lib/libclntsh.so
ln -s /home/manager/oracle_client/product/11.2.0/client_1/lib/libclntsh.so /home/manager/oracle_client/product/11.2.0/client_1/lib/libclntsh.so.10.1
5.安装DBI
#进DBI目录
#建议用root
cd DBI-1.636
#依次执行：
perl Makefile.PL
make
make test(或不执行)
make install
6.安装DBD
#进DBD目录
#建议用root
cd DBI-1.636
#依次执行：
perl Makefile.PL
make
make test(或不执行)
make install
二、报错解决：
1.Can’t locate ExtUtils/MakeMaker.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at Makefile.PL line 11.
BEGIN failed–compilation aborted at Makefile.PL line 11.
解决：
缺包
[root]yum install perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker
2.Can’t locate Digest/MD5.pm in @INC (@INC contains
缺包
yum -y install perl-Digest-MD5
3.cannot find -lclntsh
/usr/bin/ld: cannot find -lclntsh
collect2: ld returned 1 exit status
make: *** [blib/arch/auto/DBD/Oracle/Oracle.so] Error 1
就是没有更改软连接：
cd /home/manager/oracle_client/product/11.2.0/client_1/lib
rm -rf libclntsh.so
rm -rf libclntsh.so.10.1
ln -s /home/manager/oracle_client/product/11.2.0/client_1/lib/libclntsh.so.11.1 /home/manager/oracle_client/product/11.2.0/client_1/lib/libclntsh.so
ln -s /home/manager/oracle_client/product/11.2.0/client_1/lib/libclntsh.so /home/manager/oracle_client/product/11.2.0/client_1/lib/libclntsh.so.10.1
4.Can’t load ‘/usr/local/lib64/perl5/auto/DBD/Oracle/Oracle.so’ for module DBD
这个报错据说是环境变量原因，但具体不知道，按大佬说的这样处理的确解决了
vi /etc/ld.so.conf.d/oracle-x86_64.conf
echo "$ORACLE_HOME/lib" >> /etc/ld.so.conf.d/oracle-x86_64.conf && ldconfig
DBI/DBD下载连接：
DBI-1.636.tar.gz
DBD-Oracle-1.75_2.tar.gz

关于编译/usr/bin/ld: cannot find -lclntsh -小小经验分享
install_driver(Oracle) failed: Can’t load ‘/usr/local/lib/perl5/auto/DBD/Oracle/Oracle.so’ for module DBD::Oracle: libocci.so.11.1
