安装依赖

yum install libaio wget -y

检查MYSQL是否已安装、

yum list installed | grep mysql

如果有先卸载

-y remove mysql-libs.x86_64

下载MySQL官网的仓库文件

cd /tmp

wget http://repo.mysql.com/mysql80-community-release-el7-1.noarch.rpm

yum localinstall mysql80-community-release-el7-1.noarch.rpm

验证仓库是否添加成功

yum repolist enabled | grep "mysql.*-community.*"

安装MySQL

yum install mysql-community-server -y

此时MySQL 安装完成，它包含了

mysql-community-server、mysql-community-client

mysql-community-common、mysql-community-libs 四个包

执行

rpm -qi mysql-community-server.x86_64 0:8.0.16-2.el7

whereis mysql

可以看到MySQL 的安装目录是 /usr/bin/

启动服务

systemctl start mysqld

systemctl enable mysqld

systemctl status mysqld

查找初始密码

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

这里可以看到初始密码

进入mysql

mysql -uroot -p

修改初始密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '你的密码';

设置允许远程连接

mysql> use mysql;

mysql> select host,user,authentication_string,plugin from user;

mysql> update user set host='%' where user='root';

mysql> flush privileges;

查看字符编码

mysql> status

如果是【utf8mb4】那就不用改了

接下来就可以通过navicat进行连接了
