my.cnf中关于binlog的设置 binlog_fORMat = row binlog格式必须是row模式
my.cnf中关于binlog的设置 binlog_fORMat = row binlog格式必须是row模式 binlog_row_image = full 必须为full 默认就是full 准备工作 #yum intall git #yum install python-setuptools pip需要这个 #wget "https://pypi.Python.org/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate # tar -xzvf pip-1.5.4.tar.gz # cd pip-1.5.4 # python setup.py install 安装 # git clone Https://GitHub.com/danfenGCao/binlog2sql.git && cd binlog2sql # pip install -r requirements.txt 用户授权(用于binglog2sql使用) GRANT SELECT, REPLICATioN SLAVE, REPLICATION CLIENT ON *.* TO xiaomage@'localhost' identified by 'xiaomage';
select:需要读取server端information_schema.COLUMNS表,获取表结构的元信息,拼接成可视化的sql语句super/replication client:两个权限都可以,需要执行'SHOW MASTER STATUS', 获取server端的binlog列表 replication slave:通过BINLOG_DUMP协议获取binlog内容的权限

解析模式
--stop-never 持续同步binlog。可选。不加则同步至执行命令时最新的binlog位置。 -K, --no-primary-key 对INSERT语句去除主键。可选。 -B, --flashback 生成回滚语句,可解析大文件,不受内存限制,每打印一千行加一句SLEEP SELECT(1)。可选。与stop-never或no-primary-key不能同时添加。
解析范围控制
--start-file 起始解析文件。必须。 --start-position/--start-pos start-file的起始解析位置。可选。默认为start-file的起始位置。 --stop-file/--end-file 末尾解析文件。可选。默认为start-file同一个文件。 若解析模式为stop-never,此选项失效。 --stop-position/--end-pos stop-file的末尾解析位置。可选。默认为stop-file的最末位置;若解析模式为stop-never,此选项失效。 --start-datetime 从哪个时间点的binlog开始解析, 格式必须为datetime,如'2016-11-11 11:11:11'。可选。默认不过滤。 --stop-datetime 到哪个时间点的binlog停止解析,格式必须为datetime,如'2016-11-11 11:11:11'。可选。默认不过滤。
对象过滤
-d, --databases 只输出目标db的sql。可选。默认为空。 -t, --tables 只输出目标tables的sql。可选。默认为空
