Table 'performance_schema.session_status' doesn't exist和Native table 'performance_schema'.'session_status' has the wrong structure解决办法

如果从MySQL5.6升到5.7，可能会出现Table 'performance_schema.session_status' doesn't exist和Native table 'performance_schema'.'session_status' has the wrong structure这两个错误，解决办法：

执行以下指令：

mysql_upgrade -u root -p --force

然后重启MySQL：

systemctl restart mysqld

这样就正常了！！！
