1:获取mysql YUM源

进入mysql官网获取RPM包下载地址

https://dev.mysql.com/downloads/repo/yum/(根据自身的Linux操作系统版本来下载对应的mysql版本)


右击 复制链接地址 https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm


得到这个  这个就是Yum仓库的rpm包 其实就是一个下载地址


2:下载和安装mysql源

先下载 mysql源安装包

[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 

yum -y install wget

然后执行 wget https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm


安装mysql源

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


3:在线安装Mysql

yum -y install mysql-community-server

下载的东西比较多 要稍微等会;


4:启动Mysql服务

systemctl start mysqld


5:设置开机启动

[root@localhost ~]# systemctl enable mysqld

[root@localhost ~]# systemctl daemon-reload


6: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 eMV.R#mWe3ha


[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 'Caofeng2012@';

Query OK, 0 rows affected (0.00 sec)

修改密码为 Caofeng2012@    (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) 


7: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;

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'Caofeng2012@' WITH GRANT OPTION;

Query OK, 0 rows affected, 1 warning (0.01 sec)

mysql> exit;

Bye

退出下;

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

success

[root@localhost ~]# firewall-cmd --reload

success

[root@localhost ~]# 

开放3306端口


8: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:

[mysqld]

character_set_server=utf8

init_connect='SET NAMES utf8'


[root@localhost ~]# vi /etc/my.cnf

编辑保存完 重启mysql服务;

[root@localhost ~]# systemctl restart mysqld

[root@localhost ~]# 

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)


9:测试

我们用本机的sqlyog远程连接下虚拟机里的mysql
