[root@localhost ~]#注释：基本查询db表没问题，不过一些mysqldump用到设计到系统表时需要mysql_upgrade做下系统表升级；升级前使用mysqldump [root@localhost mysql]# mysqldump -uroot -p123456 -B retail_pms > /root/retail_pms.sql
mysqldump: Couldn"t execute "SHOW VARIABLES LIKE "gtid\_mode"": Native table "performance_schema"."session_variables" has the wrong structure （1682）
[root@localhost mysql]# 升级系统表[root@localhost mysql]# mysql_upgrade -u root -p123456 --socket=/var/lib/mysql/mysql3307.sock --port=3307 --force

Checking if update is needed. [root@localhost mysql]# 简单查询系统表是否存在：[root@localhost mysql]# find / -name session_variables*
/var/lib/mysql/performance_schema/session_variables.frm
/data/wonhigh/mysql3307/performance_schema/session_variables.frm [root@localhost mysql]#重启DB [root@localhost ~]# date;mysqldump -uroot -pW@h1Gh#2ol5 -A --single-transaction -q -R --set-gtid-purged=OFF > /data/all.sql;date
mysqldump: Couldn"t execute "SHOW VARIABLES LIKE "ndbinfo\_version"": Native table "performance_schema"."session_variables" has the wrong structure （1682） ---->这种需要重启DB才能解决哦~
[root@localhost ~]# [root@localhost mysql]# /etc/init.d/mysqld restart
停止 mysqld： [确定]正在启动 mysqld： [确定] [root@localhost mysql]#再尝试mysqldump是否成功[root@localhost mysql]# mysqldump -uroot -p123456 retail_pms BRAND COLOR_INFO SHOP_BRAND ITEM > /root/retail_pms.sql[root@localhost mysql]#本文永久更新链接地址
