Mysql從5.6.14安全升級至mysql5.6.25的方法,5.6.14mysql5.6.25


服務器上Mysql的版本為:社區版的mysql-community-server-5.6.14。近日局方對服務器進行漏洞掃描,發現zhyh08上的mysql存在幾個高危漏洞,要求進行修復。受這幾個漏洞影響的主要是5.6.17及以前的版本,所以將mysql升級至最新的5.6.25即可解決問題。

1、下載最新的mysql安裝包(rpm文件),鏈接如下:

MySQL-5.6.25-1.el6.x86_64.rpm-bundle.tar

2、備份數據庫數據,這裡使用的是mysqldump命令。

3、備份/etc/my.cnf:cp /etc/my.cnf /etc/my.cnf_backup

3、停止mysql服務:service mysql stop

4、解壓上面的tar包:tar -xvf MySQL-5.6.25-1.el6.x86_64.rpm-bundle.tar

5、確認服務器上所安裝的mysql的各個組件,這裡我們只升級server和client。

[hadoop@zlyh08 chx]$ rpm -qa|grep -i mysql
mysql-community-libs-compat-5.6.14-3.el6.x86_64
mysql-community-devel-5.6.14-3.el6.x86_64
mysql-community-common-5.6.14-3.el6.x86_64
mysql-community-libs-5.6.14-3.el6.x86_64
mysql-community-server-5.6.14-3.el6.x86_64
mysql-community-client-5.6.14-3.el6.x86_64
perl-DBD-MySQL-4.013-3.el6.x86_64
[hadoop@zlyh08 chx]$ 

6、將server和client卸載:

rpm -e mysql-community-server-5.6.14-3.el6.x86_64
rpm -e mysql-community-client-5.6.14-3.el6.x86_64

注:如若不先卸載的話,安裝時會報文件沖突:

[root@zlyh08 chx]# rpm -Uvh MySQL-server-5.6.25-1.el6.x86_64.rpm 
Preparing... ########################################### [100%]
file /usr/share/mysql/bulgarian/errmsg.sys from install of MySQL-server-5.6.25-1.el6.x86_64 conflicts with file from package mysql-community-common-5.6.14-3.el6.x86_64
…………

7、重新安裝server和client:

[root@zlyh08 chx]# rpm -ivh MySQL-server-5.6.25-1.el6.x86_64.rpm
Preparing... ########################################### [100%]

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.#竟然沒發現這一行,難怪裝完一直連不上
----------
[root@appserver ~]# cat /root/.mysql_secret
# The random password set for the root user at Thu Nov 20 15:52:02 2014 (local time): sFpJCf6WLhyYKc35
----------
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.

New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
[root@zlyh08 chx]# rpm -ivh MySQL-client-5.6.25-1.el6.x86_64.rpm 
Preparing... ########################################### [100%]
1:MySQL-client ########################################### [100%]
[root@zlyh08 chx]#

8、恢復my.cnf:cp /etc/my.cnf_backup /etc/my.cnf

9、啟動mysql服務:service mysql start

[root@zlyh08 chx]# service mysql start
Starting MySQL... SUCCESS!

10、使用客戶端連接mysql:

[root@zlyh08 mysql-5.6.25]# mysql
ERROR 2002 (HY000): Can t connect to local MySQL server through socket '/data1/mysql/mysql.sock' (2)

11、查看/data1/mysql目錄下,確實沒有mysql.sock文件。

12、查看/etc/my.cnf文件,發現只在[mysql]下面配置了

[mysql]
socket=/data1/mysql/mysql.sock
default-character-set=utf8
[mysqld] #mysqld下面沒有配置socket
#skip-grant-tables
interactive_timeout=300
wait_timeout=300

13、編輯/etc/my.cnf,在[mysqld]下面添加socket的配置,使用服務器和客戶端都使用同一個socket文件,如下:

[mysql]
socket=/data1/mysql/mysql.sock
default-character-set=utf8
[mysqld]
#skip-grant-tables
socket=/data1/mysql/mysql.sock #增加此行,之前只[mysql]加了這一項
interactive_timeout=300
wait_timeout=300

14、重啟mysql服務。

15、使用升級前的root用戶連接mysql:

[hadoop@zlyh08 report_script]$ mysql -hzlyh08 -uroot -p
Enter password:

16、至此,升級完成。
