mysqldump: Error 2020: Got packet bigger than ‘max

Posted 2020-12-05

今天在对公司confluence 进行mysqldump备份的时候发现了一个报错

[[email protected] mysqldump]#mysqldump --max_allowed_packet=1G -u root -p  -B -F -R -x  confluence|gzip > /mysqldump/confluence_$(date +%Y%m%d_%H%M%S).sql.gz

mysqldump: Error 2020: Got packet bigger than ‘max_allowed_packet’ bytes when dumping table `QPR` at row: 5659

[[email protected] mysqldump]# vim /etc/my.cnf

添加如下行

max_allowed_packet=512M

[[email protected] mysqldump]# service mysqld restart

第二种在线：

mysqldump --max_allowed_packet=1G -u root -p$PASSWD  -B -F -R -x  confluence > /mysqldump/confluence_$(date +%Y%m%d_%H%M%S).sql
