MySQL 5.6.19升级到 5.7.9 的步骤是什么，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。 升级前版本检查+测试表创建 [root@localhost ~]# mysql -uroot -p123456 --socket=/var/lib/mysql/mysql3307.sock --port=3307 -e"create database lottery; use lottery;create table lottery.mhq as select 'test';select version();" +-----------+ | version() | +-----------+ | 5.6.19-log | +-----------+ [root@localhost ~]# 软件包： wget http://downloads.mysql.com/archives/get/file/mysql-community-client-5.7.9-1.el6.x86_64.rpm wget http://downloads.mysql.com/archives/get/file/mysql-community-server-5.7.9-1.el6.x86_64.rpm wget http://downloads.mysql.com/archives/get/file/mysql-community-common-5.7.9-1.el6.x86_64.rpm wget http://downloads.mysql.com/archives/get/file/mysql-community-libs-5.7.9-1.el6.x86_64.rpm yum安装命令： yum install numactl* yum localinstall --skip-broken mysql-community* 升级后验证版本和表数据 [root@localhost ~]# mysql -uroot -p123456 --socket=/var/lib/mysql/mysql3307.sock --port=3307 -EN -e" select version(); select * from lottery.mhq;" *************************** 1. row *************************** 5.7.9-log *************************** 1. row *************************** test [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 mysql_upgrade: [Warning] Using a password on the command line interface can be insecure.
