centos下MySQL5.7安装教程

下载rpm包

 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

在线安装Mysql

yum -y install mysql-community-server

启动Mysql服务

systemctl start mysqld

设置开机启动

systemctl enable mysqld

systemctl daemon-reload

查看临时密码

cat /var/log/mysqld.log | grep password

修改root密码

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)

mysqladmin -u root -p password ‘xHxing!123@’

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 'xHxing!123@' WITH GRANT OPTION;

firewall-cmd --zone=public --add-port=3306/tcp --permanent

firewall-cmd --reload

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'

编辑保存完 重启mysql服务

查看下编码:

mysql> show variables like '%character%';
