阿里云centos6.8安装mysql

第一步,查看Centos下是否已经安装mysql

输入命令：yum list installed | grep mysql

第二步，删除已经安装的mysql

输入命令:yum -y remove mysql

第三步，查看yum库中的mysql(非必需的,查看版本)

输入命令： yum list | grep mysql

第四步，从yum库中的安装mysql

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

第五步，验证是否安装成功

输入命令：rpm -qi mysql-server

第六步，启动mysql服务

输入命令： service mysqld start

第七步，进入mysql

输入命令： mysql -u root

第八步，设置root密码

启动mysql:

#service mysqld start

设置root密码:

mysql_secure_installation

登陆root账号:

mysql -u root -p

建立远程root用户

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '你设置的密码' WITH GRANT OPTION;
mysql> flush privileges;

设置utf-8

查看MySQL原本的源码

mysql> show variables like 'character%';

设置编码：

# vi /etc/my.cnf

在my.cnf文件中添加如下代码：

[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

重启mysql

#service mysqld restart

再次查看编码：

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