一年一度的mysql安全月升级又开始了
CDH 元数据库升级 元数据库切换
之前使用cdh的元数据库使用的是切换节点部署模式，今年又要升级，计划在线直接升级：
1、环境描述：
系统环境：CentOS Linux release 7.4.1708 (Core） mysql环境：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、升级描述：
除去MySQL-python不用动外，其他的5个mysql包需要进行升级，我们先到mysql官网下载到每个rpm包对应的最新版本： [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、数据库备份防止升级失败：
mysqldump -uroot -p --all-databases > mysqlbak.sql
4、设置参数，使数据库关闭时会清空缓存，避免版本间缓存格式差异
mysql -u root -p --execute="SET GLOBAL innodb_fast_shutdown=0"
5、关闭数据库
systemctl stop mysqld
6、升级
[root@dip001 mysqlupdate2020]# rpm -Uvh *.rpm ################################# [100%] 正在升级/安装... 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/删除... 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、启动mysql
systemctl start mysqld
8、检查并可能解决旧数据和升级软件之间的任何不兼容性

8、验证
6.1rpm验证： rpm -qa |grep -i mysql 6.1mysql命令： mysql -V 6.3mysql系统后验证： mysql> select version();
