mysql5.6升級到mysql5.7
具體版本:
5.6.40-->5.7.30
1.下載並安裝新版本的mysql
我們這里下載5.7.30並進行安裝
2.停掉原來舊版本的數據庫
/opt/mysql5640/bin/mysqladmin -h localhost -uroot -pmysql --socket=/opt/mysql5640/data/mysql.sock shutdown
備份新版本的data目錄
[root@localhost mysql5730]# cd /opt/mysql5730
[root@localhost mysql5730]# mv data bakdata
將舊版本目錄下的data目錄拷貝到新版本(新版本已經停掉)的相應目錄下
[root@localhost mysql5640]# cd /opt/mysql5640 ##進入到舊數據庫的安裝目錄
[root@localhost mysql5640]# cp -r data /opt/mysql5730/ ##將data文件夾拷貝到新的安裝目錄
若redo日志不是放在data目錄下的話,也需要單獨拷貝到新環境的相應目錄
[root@localhost binlog]# cp binlog* /opt/mysql5730/mysqllog/binlog/
[root@localhost binlog]# pwd
/opt/mysql5640/mysqllog/binlog
3.修改目錄目錄權限
[root@localhost mysql5730]# cd /opt/mysql5730
[root@localhost mysql5730]# chown -R mysql:mysql data
4.啟動新版本數據庫
/opt/mysql5730/bin/mysqld_safe --defaults-file=/opt/mysql5730/conf/my.cnf --user=mysql &
查看啟動日志,發型很多錯誤,但是數據庫是可以啟動的

這里看到已經是新的版本了,但是還需要做升級處理
5.升級處理
/opt/mysql5730/bin/mysql_upgrade -s -pmysql -P3307
參數說明:
-s, --upgrade-system-tables
[root@localhost bin]# /opt/mysql5730/bin/mysql_upgrade -s -pmysql -P3307
mysql_upgrade: [Warning] Using a password on the command line interface can be insecure.
The --upgrade-system-tables option was used, databases won't be touched.
