CentOS7 安装和配置 mysql5.7
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
