MySQL 5.7安裝、升級(jí)筆記分享：
卸載當(dāng)前的 MySQL
查看當(dāng)前 MySQL 版本：
| [root@coderknock ~]# mysql -Vmysql Ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (i386) using readline 5.1 |
停止 MySQL 服務(wù)
| [root@coderknock ~]# service mysqld stopStopping mysqld: [ OK ] |
備份數(shù)據(jù)【數(shù)據(jù)不重要可以忽略】
備份數(shù)據(jù)庫(kù)，升級(jí)MySQL通常不會(huì)丟失數(shù)據(jù)，但保險(xiǎn)起見(jiàn)，我們需要做這一步。輸入命令：
[root@coderknock ~]# mysqldump -u xxx -h xxx -P 3306 -p --all-databases > databases.sql
卸載舊版本 MySQL
