CentOS7 安装和配置 mysql5.7

it2022-05-05  163

1.下载 mysql源安装包

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

2.安装mysql源

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

3.在线安装Mysql (下载的东西比较多 要等一会)

yum -y install mysql-community-server

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 (临时密码:fT6uZU9aH))

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

7.输入临时密码 进入mysql命令行

[root@localhost ~]# mysql -u root -p Enter password:输入临时密码

8.修改密码 (修改密码为 Zm12345@    (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) )

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Zm12345@'; Query OK, 0 rows affected (0.00 sec)

9.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 'Zm12345@' WITH GRANT OPTION; Query OK, 0 rows affected, 1 warning (0.01 sec) mysql> exit; Bye

退出后,开放3306端口

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

10.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'

11.编辑保存完 重启mysql服务

[root@localhost ~]# systemctl restart mysqld [root@localhost ~]#

12.查看下编码

mysql> show variables like '%character%';

至此,安装与配置已完成。可以使用Navicat测试连接
