CentOS 7.5 Percona Server 5.7のインストールと構成

15198 ワード

個人的にはMYSQLの軽さが好きで、今日は少し時間をかけてアリ雲の上のMYSQL 5を7 Percona-Serverに変更しました.PerconaはオープンソースのMySQL派生版で、TokuDBのデータベースエンジンはPerconaサーバに非常に魅力的で、高性能、高信頼性、高価格比のソリューションが必要な場合は、良い選択になります.
Percona Server 5.7 comes with the TokuDB storage engine. You can find more information on how to install and enable the TokuDB storage in the TokuDB Installation guide.
Installing Percona Server

#          
systemctl stop firewalld.service
systemctl disable firewalld.service
yum install http://www.percona.com/downloads/percona-release/redhat/0.1-6/percona-release-0.1-6.noarch.rpm
yum list | grep percona
yum install Percona-Server-server-57
#   mysql   
systemctl restart mysqld.service
systemctl enable mysqld.service
systemctl status mysqld.service
#    
/etc/my.cnf
/var/lib/mysql
/var/log/mysqld.log
#  mysql    
grep 'temporary password' /var/log/mysqld.log
mysql -uroot -p
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';
#      
use mysql; 
mysql>update user set host = '%' where user = 'root'; 
mysql>select host, user from user;

セキュリティ構成(mysql以外の公式ドキュメントはmysql 6.xバージョンのみ)

[root@iZ11fek1j6cZ lib]# mysql_secure_installation 

Securing the MySQL server deployment. 

Enter password for user root: 
The 'validate_password' plugin is installed on the server. 
The subsequent steps will run with the existing configuration 
of the plugin. 
Using existing password for root. 

Estimated strength of the password: 100 
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n 

... skipping. 
By default, a MySQL installation has an anonymous user, 
allowing anyone to log into MySQL without having to have 
a user account created for them. This is intended only for 
testing, and to make the installation go a bit smoother. 
You should remove them before moving into a production 
environment. 

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y 
Success. 


Normally, root should only be allowed to connect from 
'localhost'. This ensures that someone cannot guess at 
the root password from the network. 

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n 

... skipping. 
By default, MySQL comes with a database named 'test' that 
anyone can access. This is also intended only for testing, 
and should be removed before moving into a production 
environment. 

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y 
- Dropping test database... 
Success. 

- Removing privileges on test database... 
Success. 

Reloading the privilege tables will ensure that all changes 
made so far will take effect immediately. 

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y 
Success. 

All done!
