bin2sql安装
已测试环境
Python 2.7, 3.4+
MySQL 5.6, 5.7
我在centos6.9安装得,默认python2.6,不符合要求,需要安装一个3.4.4得版本才行
python3.4.4下载: https://www.python.org/downloads/source/
mysql我用的是5.7的,符合要求
python3.4.4安装
cd /data/Python-3.4.4
./configure --prefix=/usr/local/python3
make
make install
python3+以上的,自带了pip,所以不需要自己另外安装pip了
pip地址:/usr/local/python3/bin/pip3
bin2sql除了需要依赖pip,还需要依赖PyMySQL ,python-mysql-replication,wheel argparse
yum -y install epel-release #安装epel源
yum -y install git #安装git
cd /data
git clone https://github.com/danfengcao/binlog2sql.git && cd binlog2sql #通过git拉取bin2sql源码包
/usr/local/python3/bin/pip3 install -r requirements.txt #pip来安装 PyMySQL ,python-mysql-replication,wheel argparse和安装bin2sql
开始进行闪回
在主slave上创建一个用户,用于闪回
GRANT SELECT, REPLICATION SLAVE, REPLICATION CLIENT ON *.* TO chen@'%' identified by '123456';
从一个binlog文件解析出标准的SQL语句
cd /data/binlog2sql/binlog2sql
/usr/local/python3/bin/pip3 binlog2sql.py -h127.0.0.1 -P3306 -uchen -p'123456'-dmei -t student --start-file='mysql-bin.000002' #就会获取到mysql-bin.000002这个binlog文件的里面所有执行过的sql
获取闪回语句
cd /data/binlog2sql/binlog2sql
/usr/local/python3/bin/pip3
binlog2sql.py --flashback -h127.0.0.1 -P3306 -uchen -p'123456'-dmei -t student
--start-file='mysql-bin.000002' >/data/20191128.sql
闪回:
/usr/local/mysql/bin/mysql -uroot -p123456 mei < /data/20191128.sql
