阿里雲安裝mysql5.7

1.配置YUM源

下載mysql源安裝包:

wget https://repo.mysql.com//mysql57-community-release-el7-11.noarch

安裝mysql源,安裝過程當中遇到Is this ok [y/d/N]的直接輸入y便可:

yum localinstall mysql57-community-release-el7-11.noarch.rpm

檢查mysql源是否安裝成功:

yum repolist enabled | grep "mysql.*-community.*"

2.安裝MySQL,安裝過程當中遇到Is this ok [y/d/N]的直接輸入y便可

yum install mysql-community-server

Note:可經過修改/etc/yum.repos.d/mysql-community.repo源中的enabled【1表示選擇】的值來選擇安裝的MySQL版本

3.啓動MySQL服務

systemctl start mysqld

查看MySQL的啓動狀態

systemctl status mysqld

4.開機啓動

systemctl enable mysqld

systemctl daemon-reload

5.修改root本地登陸密碼

獲取MySQL默認密碼:

grep 'temporary password' /var/log/mysqld.log

登錄MySQL:

mysql -uroot -p

修改默認密碼:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'Password';

或者

set password for 'root'@'localhost'=password('Password');

Note:MySQL5.7默認安裝了密碼安全檢查插件(validate_password),默認密碼檢查策略要求密碼必須包含:大小寫字母、數字和特殊符號,而且長度不能少於8位。?

6.添加遠程登陸用戶

默認只容許root賬戶在本地登陸,若是要在其它機器上鍊接mysql,必須修改root容許遠程鏈接,或者添加一個容許遠程鏈接的賬戶:

GRANT ALL PRIVILEGES ON *.* TO 'account'@'%' IDENTIFIED BY 'pwd' WITH GRANT OPTION;

7.配置默認編碼爲utf8

show variables like '%character%';

修改/etc/my.cnf配置文件:

[mysqld]

character_set_server=utf8

init_connect='SET NAMES utf8'

從新啓動mysql服務便可完成修改

8.默認配置文件路徑

配置文件:/etc/my.cnf

日誌文件:/var/log//var/log/mysqld.log

服務啓動腳本:/usr/lib/systemd/system/mysqld.service

socket文件:/var/run/mysqld/mysqld.pid
