[root@localhost ~]# wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

-bash: wget: 未找到命令

我们先安装下wget

[root@localhost ~] yum -y install wget

然后执行

[root@localhost ~] wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm

安装mysql源

[root@localhost ~] yum -y localinstall mysql57-community-release-el7-11.noarch.rpm

第三步:在线安装Mysql

[root@localhost ~] yum -y install mysql-community-server

下载的东西比较多 要稍微等会;

第四步:启动Mysql服务

[root@localhost ~] systemctl start mysqld

第五步:设置开机启动

[root@localhost ~]# systemctl enable mysqld
[root@localhost ~]# systemctl daemon-reload

第六步:修改root本地登录密码

mysql安装完成之后,在/var/log/mysqld.log文件中给root生成了一个临时的默认密码

[root@localhost ~]# vi /var/log/mysqld.log

这里的临时密码

[root@localhost ~]# mysql -u root -p

Enter password:

输入临时密码 进入mysql命令行;

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Aabbcc@';
Query OK, 0 rows affected (0.00 sec)

修改密码为 Aabbcc@ (备注 mysql5.7默认密码策略要求密码必须是大小写字母数字特殊字母的组合,至少8位)

第七步:设置允许远程登录

Mysql默认不允许远程登录,我们需要设置下,并且防火墙开放3306端口;

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Aabbcc@' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> exit;

退出下;

开放3306端口

[root@localhost ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
[root@localhost ~]# firewall-cmd --reload
success

第八步:配置默认编码为utf8

修改/etc/my.cnf配置文件,在[mysqld]下添加编码配置,如下所示:

[root@localhost ~]# vi /etc/my.cnf
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'

编辑保存完 重启mysql服务;

[root@localhost ~]# systemctl restart mysqld

查看下编码:

mysql> show variables like '%character%';

+--------------------------+----------------------------+

| Variable_name | Value |

+--------------------------+----------------------------+

| character_set_client | utf8 |

| character_set_connection | utf8 |

| character_set_database | utf8 |

| character_set_filesystem | binary |

| character_set_results | utf8 |

| character_set_server | utf8 |

| character_set_system | utf8 |

| character_sets_dir | /usr/share/mysql/charsets/ |

+--------------------------+----------------------------+

8 rows in set (0.00 sec)

第九步:测试

我们用本机的sqlyog远程连接下虚拟机里的mysql

OK 至此 Mysql安装配置完毕;
