第一步,查看Centos下是否已經(jīng)安裝mysql

輸入命令：yum list installed | grep mysql

第二步，刪除已經(jīng)安裝的mysql

輸入命令:yum -y remove mysql

第三步，查看yum庫中的mysql(非必需的,查看版本)

輸入命令： yum list | grep mysql

第四步，從yum庫中的安裝mysql

輸入命令: yum -y install mysql mysql-server mysql-devel

第五步，驗(yàn)證是否安裝成功

輸入命令：rpm -qi mysql-server

第六步，啟動mysql服務(wù)

輸入命令： service mysqld start

第七步，進(jìn)入mysql

輸入命令： mysql -u root

第八步，設(shè)置root密碼

啟動mysql:

#service mysqld start

設(shè)置root密碼:

mysql_secure_installation

登陸root賬號:

mysql -u root -p

建立遠(yuǎn)程root用戶

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你設(shè)置的密碼' WITH GRANT OPTION;
mysql> flush privileges;

設(shè)置utf-8

查看MySQL原本的源碼

mysql> show variables like 'character%';

設(shè)置編碼：

# vi /etc/my.cnf

在my.cnf文件中添加如下代碼：

[mysqld]
character-set-server=utf8 
collation-server=utf8_general_ci 
sql_mode='NO_ENGINE_SUBSTITUTION'

[mysql]
default-character-set = utf8

[mysql.server]
default-character-set = utf8


[mysqld_safe]
default-character-set = utf8


[client]
default-character-set = utf8

重啟mysql

#service mysqld restart

再次查看編碼：

# mysql -uroot -p
mysql> show variables like 'character%';
