尝试用pt-slave-restart跳过该错误
[root@pxc01 percona-toolkit-3.0.3]# pt-slave-restart --error-numbers=1062 -h localhost -uroot -pmysql
Can't locate Digest/MD5.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/bin/pt-slave-restart line 4261.
BEGIN failed--compilation aborted at /usr/local/bin/pt-slave-restart line 4261.



缺少安装了包,安装之。
yum -y install perl-Digest-MD5



再次执行
[root@pxc01 /]# pt-slave-restart --error-numbers=1062 -h localhost -uroot -pmysql -S /tmp/mysql.sock   
Cannot skip transactions properly because GTID is enabled and slave_parallel_workers > 0.  See 'GLOBAL TRANSACTION IDS' in the tool's documentation.



报错误,因为slave_parallel_workers 大于0,查看当前slave_parallel_workers=8
mysql> show variables like '%slave_parallel_workers%';
+------------------------+-------+
| Variable_name          | Value |
+------------------------+-------+
| slave_parallel_workers | 8     |
+------------------------+-------+
1 row in set (0.00 sec)



先设置0,设置slave_parallel_workers=0
mysql> set global slave_parallel_workers=0;

[root@pxc01 /]# pt-slave-restart --error-numbers=1062 -h localhost -uroot -pmysql -S /tmp/mysql.sock
2018-05-18T20:54:55 S=/tmp/mysql.sock,h=localhost,p=...,u=root relaylog.000214         317 1062 
2018-05-18T20:54:56 S=/tmp/mysql.sock,h=localhost,p=...,u=root relaylog.000214        1229 1062 


执行成功,查看复制情况:

已经恢复正常了,将slave_parallel_workers恢复回原来的值.
mysql> set global slave_parallel_workers=8;
Query OK, 0 rows affected (0.00 sec)
