第一步: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/
点击 下载
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
第二步:下载和安装mysql源
先下载 mysql源安装包
[[email protected] ~]# 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
第三步:在线安装Mysql
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
systemctl start mysqld
第五步:设置开机启动
[[email protected] ~]# systemctl enable mysqld
[[email protected] ~]# 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。
[[email protected] ~]# vi /var/log/mysqld.log
这里的临时密码 eMV.R#mWe3ha
[[email protected] ~]# 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 ‘[email protected]‘;
Query OK, 0 rows affected (0.00 sec)
修改密码为 [email protected] (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;
mysql> GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘[email protected]‘ WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> exit;
Bye
退出下;
[[email protected] ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
[[email protected] ~]# firewall-cmd --reload
success
[[email protected] ~]#
开放3306端口
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:
[mysqld]
character_set_server=utf8
init_connect=‘SET NAMES utf8‘
[[email protected] ~]# vi /etc/my.cnf
编辑保存完 重启mysql服务;
[[email protected] ~]# systemctl restart mysqld
[[email protected] ~]#
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;
