安裝包下載
下載最新的 OGG FOR MySQL，這里使用的是
ggs_121210_Linux_x64_MySQL_64bit.zip
官方下載地址：
http://www.oracle.com/technetwork/cn/middleware/goldengate/downloads/index.html

source 和 target 端的 OGG 安裝
創建 OGG 主目錄
mkdir /ogg
解壓安裝包，會得到一個 tar 文件
unzip ggs_121210_Linux_x64_MySQL_64bit.zip
將 tar 文件移至 OHGG 主目錄，并解壓即可
mv ggs_Linux_x64_MySQL_64bit.tar /ogg/
tar xvf ggs_Linux_x64_MySQL_64bit.tar
修改環境變量
vi ~/.bash_profile
加入如下三個變量
export GGHOME=/ogg
export PATH=$PATH:$GGHOME
export LD_LIBRARY_PATH=/ogg:$LD_LIBRARY_PATH

登入 OGG 創建 OGG 的相關目錄
[root@20_138-Mysql_Test1 ogg]# ./ggsci

初始化數據
主庫 master-data 方式導出 oggtest 庫，該方式會記錄導出時的 log_file 信息
mysqldump -uroot -p –master-DATA oggtest oggtest.sql

打開 oggtest.sql 找到下面內容，記錄下 log_file 和 log_pos
CHANGE MASTER TO MASTER_LOG_FILE= mysql-bin.000003 , MASTER_LOG_POS=5054;

修改 extract e1 從導出的時的 binlog 開始抽取
GGSCI (20_138-Mysql_Test1 DBLOGIN AS root) 54 ALTER EXTRACT e1,VAM,lognum 3,logpos 5054
EXTRACT altered.

開啟同步
開啟抽取進程
GGSCI (20_138-Mysql_Test1 DBLOGIN AS root) 59 START e1
Sending START request TO MANAGER …
EXTRACT E1 STARTING
開啟投遞進程
GGSCI (20_138-Mysql_Test1 DBLOGIN AS root) 59 START P1
Sending START request TO MANAGER …

target 端開啟應用進程
GGSCI (20_139-Mysql_Test2 DBLOGIN AS root) 5 START r1

REPLICAT RUNNING R1 00:00:00 00:00:09
主庫插入數據，觀察 ogg 日志信息，備庫查看是否同步，查錯拍錯
