我使用VBOX虚拟机，一台已经安装ORACLE数据库与GOLDENDGATE的主机。另一台只安装了ORACLE数据库。配置数据库环境、goldengate用户

环境：我使用VBOX虚拟机，一台已经安装Oracle数据库与GOLDENDGATE的主机。另一台只安装了ORACLE数据库。
配置数据库环境、goldengate用户，安装GoldenGate等操作参考：两台Oracle之间配置OGG-未配置同步DDL

一.安装MYSQL 安装MYSQL数据库客户端：

[root@bys2 ~]# mount /dev/cdrom /mnt/cdrom/
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@bys2 ~]# rpm -qa mysql
[root@bys2 ~]# cd /mnt/cdrom/
[root@bys2 cdrom]# yum -y install mysql
安装服务器端
[root@bys2 cdrom]# yum -y install mysql-server
[root@bys2 cdrom]# rpm -qa mysql*
mysql-5.0.77-4.el5_6.6
mysql-server-5.0.77-4.el5_6.6
##########################
启动MYSQL
[root@bys2 cdrom]# service mysqld status
mysqld is stopped
[root@bys2 cdrom]# service mysqld start
Starting MySQL: [ OK ]

创建用来做同步的用户和表

[oracle@bys2 ~]$ mysql -u root
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| test |
+--------------------+
3 rows in set (0.00 sec)
mysql> create database oggtest;
Query OK, 1 row affected (0.00 sec)
mysql> use oggtest;
Database changed
mysql> grant all privileges on *.* to 'root'@'%' identified by '123456';
Query OK, 0 rows affected (0.01 sec)
mysql> grant all privileges on *.* to 'ogg'@'%' identified by 'ogg';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> use oggtest
Database changed
mysql> show tables;
Empty set (0.00 sec)
mysql> create table test5(aa int primary key) engine=innodb;
Query OK, 0 rows affected (0.02 sec)
mysql> show tables;
+-------------------+
| Tables_in_oggtest |
+-------------------+
| test5 |
+-------------------+
1 row in set (0.00 sec)
mysql> select * from test5;
Empty set (0.01 sec)
退出后使用[oracle@bys2 mysqlogg]$ mysql -u root -p 进行登陆测试，确认使用 root用户及密码可以登陆。
如不能登陆，可以参考：

二.安装OGG-FOR-MYSQL
[oracle@bys2 ~]$ tar -xvf ggs_Linux_x86_MySQL_32bit.tar -C /u01/mysqlogg/
[oracle@bys2 mysqlogg]$ pwd
/u01/mysqlogg
[oracle@bys2 mysqlogg]$ ./ggsci
