升級

MySQL數據庫升級3.6.39

準備工作：
1.新建目錄（把升級文件放在此目錄中）
[root@localhost /]# mkdir /mysqlbak
[root@localhost /]#
2.上傳升級的數據庫版本：
.https://cdn.mysql.com//Downloads/MySQL-5.6/MySQL-5.6.39-1.el7.x86_64.rpm-bundle.tar

3.解壓
[root@localhost mysqlbak]# tar vxf MySQL-5.6.39-1.el7.x86_64.rpm-bundle.tar
MySQL-shared-compat-5.6.39-1.el7.x86_64.rpm

MySQL-client-5.6.39-1.el7.x86_64.rpm
MySQL-devel-5.6.39-1.el7.x86_64.rpm
MySQL-server-5.6.39-1.el7.x86_64.rpm
MySQL-shared-5.6.39-1.el7.x86_64.rpm
MySQL-test-5.6.39-1.el7.x86_64.rpm
MySQL-embedded-5.6.39-1.el7.x86_64.rpm

備份數據庫
註：升級數據庫理論是不影響數據的，安全起見備份數據庫
[root@localhost /]# mysqldump -uroot -P 3306 -p -A > /mysqlbak/dabatases.sql

Enter password:
You have new mail in /var/spool/mail/root
[root@localhost /]#

停止數據庫
[root@localhost mysqlbak]# service crond stop
Redirecting to /bin/systemctl stop crond.service
You have new mail in /var/spool/mail/root
[root@localhost mysqlbak]# service mysql stop
Shutting down MySQL..................... SUCCESS!

[root@localhost mysqlbak]# netstat -lntup | grep 3306
[root@localhost mysqlbak]#

刪除舊版本MySQL包文件
[root@localhost mysqlbak]# yum remove MySQL-share MySQL-client MySQL-devel MySQL-server MySQL-shared

安裝新的MySQL包文件
