一年一度的mysql安全月升級又開始了
CDH 元數據庫升級 元數據庫切換
之前使用cdh的元數據庫使用的是切換節點部署模式，今年又要升級，計划在線直接升級：
1、環境描述：
系統環境：CentOS Linux release 7.4.1708 (Core） mysql環境：2.7.25 [root@dip001 dip]# rpm -qa |grep -i mysql mysql-community-client-5.7.25-1.el7.x86_64 mysql-community-libs-compat-5.7.25-1.el7.x86_64 mysql-community-libs-5.7.25-1.el7.x86_64 MySQL-python-1.2.5-1.el7.x86_64 mysql-community-common-5.7.25-1.el7.x86_64 mysql-community-server-5.7.25-1.el7.x86_64
2、升級描述：
除去MySQL-python不用動外，其他的5個mysql包需要進行升級，我們先到mysql官網下載到每個rpm包對應的最新版本： [root@dip001 lzm]# cd mysqlupdate2020/ [root@dip001 mysqlupdate2020]# ll -rw-rw-r-- 1 dip dip 26452496 6月 5 13:48 mysql-community-client-5.7.30-1.el7.x86_64.rpm -rw-rw-r-- 1 dip dip 318688 6月 5 13:48 mysql-community-common-5.7.30-1.el7.x86_64.rpm -rw-rw-r-- 1 dip dip 2459484 6月 5 13:48 mysql-community-libs-5.7.30-1.el7.x86_64.rpm -rw-rw-r-- 1 dip dip 1263752 6月 5 13:48 mysql-community-libs-compat-5.7.30-1.el7.x86_64.rpm -rw-rw-r-- 1 dip dip 181564660 6月 5 13:49 mysql-community-server-5.7.30-1.el7.x86_64.rpm [root@dip001 mysqlupdate2020]#
3、數據庫備份防止升級失敗：
mysqldump -uroot -p --all-databases > mysqlbak.sql
4、設置參數，使數據庫關閉時會清空緩存，避免版本間緩存格式差異
mysql -u root -p --execute="SET GLOBAL innodb_fast_shutdown=0"
5、關閉數據庫
systemctl stop mysqld
6、升級
[root@dip001 mysqlupdate2020]# rpm -Uvh *.rpm ################################# [100%] 正在升級/安裝... 1:mysql-community-common-5.7.30-1.e################################# [ 10%] 2:mysql-community-libs-5.7.30-1.el7################################# [ 20%] 3:mysql-community-client-5.7.30-1.e################################# [ 30%] 4:mysql-community-server-5.7.30-1.e################################# [ 40%] 5:mysql-community-libs-compat-5.7.3################################# [ 50%] 正在清理/刪除... 6:mysql-community-server-5.7.25-1.e################################# [ 60%] 7:mysql-community-client-5.7.25-1.e################################# [ 70%] 8:mysql-community-libs-compat-5.7.2################################# [ 80%] 9:mysql-community-libs-5.7.25-1.el7################################# [ 90%] 10:mysql-community-common-5.7.25-1.e################################# [100%]
7、啟動mysql
systemctl start mysqld
8、檢查並可能解決舊數據和升級軟件之間的任何不兼容性

8、驗證
6.1rpm驗證： rpm -qa |grep -i mysql 6.1mysql命令： mysql -V 6.3mysql系統后驗證： mysql> select version();
