MySQL使用mysqldump导出数据报错
mysql mysqldump: Error 2020: Got packet bigger than 'max_allowed_packet' bytes when dumping table
解决方法： 在导出时加上--max_allowed_packet参数
[root@db-backup data]# mysqldump -urepl -p -h 10.11.10.243 -P 3306 --max_allowed_packet=512M -q \ --single-transaction --master-data=2 --databases xxx > /data/20180810_xxx.sql [root@db-backup data]# mysqldump --help|grep max postgresql, oracle, mssql, db2, maxdb, no_key_options, --max-allowed-packet=# The maximum packet length to send to or receive from max-allowed-packet 25165824
