通过yum安装percona-toolkit
[root@node01 ~]# wget https://repo.percona.com/yum/percona-release-latest.noarch.rpm
[root@node01 ~]# rpm -ivh percona-release-latest.noarch.rpm
[root@node01 ~]# yum install -y percona-toolkit
[mysql@node01 ~]$ pt-table-checksum --version
pt-table-checksum 3.5.4
从库只读，从库与主库的数据保持一致
[mysql@node01 ~]$ pt-table-checksum --user=root --ask-pass --host=192.168.1.101 --port=3306 --databases=tpcc10 \
--replicate=tpcc10.checksums --nocheck-replication-filters --nocheck-binlog-format --noversion-check

在从库执行DML事务模拟与主库数据不一致
[mysql@node02 ~]$ mysql -uroot -pabcd.1234 -e 'set global super_read_only=0'
[mysql@node02 ~]$ tpcc-mysql/tpcc_start -h node02 -P 3306 -d tpcc10 -u tpcc -p tpcc -w 10 -c 10 -l 60
校验从库与主库的数据是否一致，因为在从库执行事务导致与主库多个表数据不一致
[mysql@node01 ~]$ pt-table-checksum --user=root --ask-pass --host=192.168.1.101 --port=3306 --databases=tpcc10 \
--replicate=tpcc10.checksums --nocheck-replication-filters --nocheck-binlog-format --noversion-check

通过pt-table-sync同步从库与主库数据不一致的表
[root@node01 ~]# pt-table-sync --version
pt-table-sync 3.5.2
打印同步从库与主库数据不一致的表的sql语句
[mysql@node01 ~]$ pt-table-sync --print --replicate=tpcc10.checksums \
h=192.168.1.101,u=root,p=abcd.1234 h=192.168.1.102,u=root,p=abcd.1234 >diffs.sql
执行同步从库与主库数据不一致的表的sql语句
[mysql@node01 ~]$ pt-table-sync --execute --replicate=tpcc10.checksums \
h=192.168.1.101,u=root,p=abcd.1234 h=192.168.1.102,u=root,p=abcd.1234 --noforeign-key-checks
再次校验从库与主库的表数据是否一致，全部表数据一致
[mysql@node01 ~]$ pt-table-checksum --user=root --ask-pass --host=192.168.1.101 --port=3306 --databases=tpcc10 \
--replicate=tpcc10.checksums --nocheck-replication-filters --nocheck-binlog-format --noversion-check
