ora2pg官网：Ora2Pg：将 Oracle 迁移到 PostgreSQL (darold.net)

1、安装oracle

oracle11g

2、安装pg12

pg12

3、安装perl

官网：DBI-1.643 - Database independent interface for Perl - metacpan.org

DBI，Database Independent Interface，是Perl语言连接数据库的接口

复制代码

yum install -y perl perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker
cd /root
wget https://cpan.metacpan.org/authors/id/T/TI/TIMB/DBI-1.643.tar.gz
tar -xvf DBI-1.643.tar.gz
cd DBI-1.643
perl Makefile.PL
make
make install

4、安装DBD::Pg模块

DBD-Pg-3.18.0 - DBI PostgreSQL interface - metacpan.org

The usual steps to install DBD::Pg:

perl Makefile.PL

make install

Do steps 1 to 2 as a normal user, not as root!

复制代码

cd /opt
wget https://cpan.metacpan.org/authors/id/T/TU/TURNSTEP/DBD-Pg-3.18.0.tar.gz
tar -xvf DBD-Pg-3.18.0.tar.gz

#授权给非root用户
chown pg127:pg127 DBD-Pg-3.18.0 -R
cd DBD-Pg-3.18.0
export POSTGRES_INCLUDE="/usr/local/pg127/include"
export POSTGRES_LIB="/usr/local/pg127/lib"
perl Makefile.PL
make

#切换到root
su - root
cd /opt/DBD-Pg-3.18.0
make install

5、安装DBD::Oracle模块

DBD::Oracle - Oracle database driver for the DBI module - metacpan.org

复制代码

cd /opt
wget https://cpan.metacpan.org/authors/id/P/PY/PYTHIAN/DBD-Oracle-1.74.tar.gz
tar -xvf DBD-Oracle-1.74.tar.gz
cd DBD-Oracle-1.74/

6、安装ora2pg
