本篇文章为大家展示了如何理解ogg12 mysql to oracle单向同步，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。 环境： 192.168.91.137 (Mysql) —> 192.168.91.138 ( Oracle ) 版本： 操作系统：centOS 6.5 Mysql: 5.7.17 Oracle： 11.2.0.4 goldengate: 12.2.0.1 for oracle 12.2.0.1 for mysql 一、源端安装配置【Mysql】 1、vim /etc/profile export MYSQL_HOME=/usr/local/mysql export PATH=$PATH:$MYSQL_HOME/bin source /etc/profile 2、添加一个mysql组 groupadd -g 1000 mysql passwd mysql 3、添加一个用户 useradd -u 1000 -g mysql mysql passwd mysql 4、解压缩下载的包 cd /usr/local/ tar -xzvf /usr/local/mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz tar -xzvf /usr/local/mysql-test-5.7.17-linux-glibc2.5-x86_64.tar.gz 5、然后 mv 解压后的包,重命名mysql mv mysql-5.7.17-linux-glibc2.5-x86_64 mysql 6、进入mysql包中， 给这个包授权 给mysql chown -R mysql:mysql /usr/local/mysql chmod -R 755 /usr/local/mysql 7、进入mysql文件名 basedir 为mysql 的路径， datadir 为mysql的 data 包，里面存放着mysql自己的包， 如user [root@ogg1 local]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 2017-04-07T02:50:57.483315Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). 2017-04-07T02:51:00.090256Z 0 [Warning] InnoDB: New log files created, LSN=45790 2017-04-07T02:51:00.505229Z 0 [Warning] InnoDB: Creating foreign key constraint system tables. 2017-04-07T02:51:00.708487Z 0 [Warning] No existing UUID has been found, so we assume that this is the first time that this server has been started. Generating a new UUID: 08775cba-1b3d-11e7-8520-000c29439f01. 2017-04-07T02:51:00.733003Z 0 [Warning] Gtid table is not ready to be used. Table 'mysql.gtid_executed' cannot be opened. 2017-04-07T02:51:00.735871Z 1 [Note] A temporary password is generated for root@localhost: EdgZSS;6=hqD 注：此处需要注意记录生成的临时密码，如上文： 8、安装SSL [root@ogg1 local]# /usr/local/mysql/bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data Generating a 2048 bit RSA private key .......................................................................................+++ ...............................................+++ writing new private key to 'ca-key.pem' ----- Generating a 2048 bit RSA private key ....................................+++ .........+++ writing new private key to 'server-key.pem' ----- Generating a 2048 bit RSA private key ................................................................................................................................................................+++ ..............................................................................+++ writing new private key to 'client-key.pem' 9、进入support-files，拷贝参数文件 [root@ogg1 local]# cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf [root@ogg1 local]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql 10、修改配置文件中的内容 [root@ogg1 local]# vim /etc/init.d/mysql basedir=/usr/local/mysql datadir=/usr/local/mysql/data [root@ogg1 local]# vim /etc/my.cnf basedir=/usr/local/mysql datadir=/usr/local/mysql/data port=3306 socket=/tmp/mysql.sock character-set-server=utf8 log_timestamps=system user=mysql binlog_format=row server-id=1 log-bin=mysql-bin 注：如果vim /etc/my.cnf 只配置 log-bin=mysql-bin，没配置server-id=1。会报如下错误 Starting MySQL. ERROR! The server quit without updating PID file (/usr/local/mysql/data/ogg1.pid). 11、启动mysql [root@ogg1 local]# /usr/local/mysql/bin/mysqld_safe --user=mysql & 12、另开个窗口，输入临时密码:EdgZSS;6=hqD (见第七步操作最后) [root@ogg1 ~]# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 3 Server version: 5.7.17 Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or 'h' for help. Type 'c' to clear the current input statement. 13、修改密码 mysql> set password=password('manager2017'); Query OK, 0 rows affected, 1 warning (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) 14、查看设置的参数是否生效： mysql> show master status; +------------------+----------+--------------+------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +------------------+----------+--------------+------------------+-------------------+ | mysql-bin.000001 | 154 | | | | +------------------+----------+--------------+------------------+-------------------+ 1 row in set (0.00 sec) mysql> show variables like '%log_bin%'; +---------------------------------+---------------------------------------+ | Variable_name | Value | +---------------------------------+---------------------------------------+ | log_bin | ON | | log_bin_basename | /usr/local/mysql/data/mysql-bin | | log_bin_index | /usr/local/mysql/data/mysql-bin.index | | log_bin_trust_function_creators | OFF | | log_bin_use_v1_row_events | OFF | | sql_log_bin | ON | +---------------------------------+---------------------------------------+ 6 rows in set (0.01 sec) mysql> show variables like '%binlog%'; +-----------------------------------------+----------------------+ | Variable_name | Value | +-----------------------------------------+----------------------+ | binlog_cache_size | 32768 | | binlog_checksum | CRC32 | | binlog_direct_non_transactional_updates | OFF | | binlog_error_action | ABORT_SERVER | | binlog_format | ROW | | binlog_group_commit_sync_delay | 0 | | binlog_group_commit_sync_no_delay_count | 0 | | binlog_gtid_simple_recovery | ON | | binlog_max_flush_queue_time | 0 | | binlog_order_commits | ON | | binlog_row_image | FULL | | binlog_rows_query_log_events | OFF | | binlog_stmt_cache_size | 32768 | | innodb_api_enable_binlog | OFF | | innodb_locks_unsafe_for_binlog | OFF | | log_statements_unsafe_for_binlog | ON | | max_binlog_cache_size | 18446744073709547520 | | max_binlog_size | 1073741824 | | max_binlog_stmt_cache_size | 18446744073709547520 | | sync_binlog | 1 | +-----------------------------------------+----------------------+ 20 rows in set (0.01 sec) mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | +--------------------+ mysql> create database test; Query OK, 1 row affected (0.07 sec) mysql> create table t1 (name char(10)); Query OK, 0 rows affected (0.13 sec) mysql> show table status from test like 't1'; +-------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+-------------+------------+-----------------+----------+----------------+---------+ | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_length | Max_data_length | Index_length | Data_free | Auto_increment | Create_time | Update_time | Check_time | Collation | Checksum | Create_options | Comment | +-------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+-------------+------------+-----------------+----------+----------------+---------+ | t1 | InnoDB | 10 | Dynamic | 0 | 0 | 16384 | 0 | 0 | 0 | NULL | 2017-04-07 14:56:21 | NULL | NULL | utf8_general_ci | NULL | | | +-------+--------+---------+------------+------+----------------+-------------+-----------------+--------------+-----------+----------------+---------------------+-------------+------------+-----------------+----------+----------------+---------+ 1 row in set (0.00 sec) 二、安装mysql版本的goldengate 下载相应的OGG软件。http://www.oracle.com/technetwork/middleware/goldengate/downloads/index.html 源端用mysql用户安装gg： 1、设置环境变量 vi .bash_profile export GG_HOME=/home/mysql/ggs export MYSQL_HOME=/usr/local/mysql export LD_LIBRARY_PATH=$MYSQL_HOME/lib:/usr/lib:/usr/local/lib export PATH=$GG_HOME:$PATH source ~/.bash_profile [mysql@ogg1]$ unzip ggs_Linux_x64_MySQL_64bit.zip [mysql@ogg1]$ mkdir -p ./ggs [mysql@ogg1]$ tar -xvf ggs_Linux_x64_MySQL_64bit.tar -C ./ggs [mysql@ogg1]$ cd ./ggs 2、配置gg参数 [mysql@ogg1 ggs]$ ./ggsci Oracle GoldenGate Command Interpreter for MySQL Version 12.2.0.1.1 OGGCORE_12.2.0.1.0_PLATFORMS_151211.1401 Linux, x64, 64bit (optimized), MySQL Enterprise on Dec 11 2015 16:23:51 Operating system character set identified as UTF-8.
