[root@confluence 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

[root@confluence mysqldump] # vim / etc/my.cnf

Add as follows

Max_allowed_packet=512M

[root@confluence mysqldump] # service mysqld restart

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