本文主要介绍以下两点:
一. 如何安装Mysql8.0
二. Navicat连接Mysql
安装mysql8.0">一. 如何安装Mysql8.0
安装Mysql有两种方式:
直接下载官方的源(比较慢)
https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm # 下载rpm包yum localinstall mysql80-community-release-el7-1.noarch.rpm # 处理相关依赖
yum install mysql-community-server # 安装
用163的源,分开安装
wget https://mirrors.163.com/mysql/Downloads/MySQL-8.0/mysql-community-common-8.0.18-1.el7.x86_64.rpmwget https://mirrors.163.com/mysql/Downloads/MySQL-8.0/mysql-community-libs-8.0.18-1.el7.x86_64.rpm
wget https://mirrors.163.com/mysql/Downloads/MySQL-8.0/mysql-community-client-8.0.18-1.el7.x86_64.rpm
wget https://mirrors.163.com/mysql/Downloads/MySQL-8.0/mysql-community-server-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-common-8.0.18-1.el7.x86_64.rpm # rpm下载
rpm -ivh mysql-community-libs-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.0.18-1.el7.x86_64.rpm
重启Mysql
service mysqld start
查看Mysql默认密码
cat /var/log/mysqld.log | grep password
登录
mysql -uroot -p # 回车,复制上面的密码即可
二. Navicat连接Mysql
连接mysql之前,先修改下root的密码
set global validate_password.policy=0; #修改策略set global validate_password.length=1;
alter user 'root'@'localhost' identified with mysql_native_password by '12345678'; # 测试环境,密码可以简单点,Mysql8.0必须用mysql_native_password给账号加密
可以exit退出,重新登录看看。
修改root账号的Host,便于IP连接
use mysql; #mysql的基础表update user set Host = '%' where User='root'; # 正式环境,可以创建新的Mysql账号,设置成具体的ip
开放3306端口
firewall-cmd --add-port=3306/tcp --permanentfirewall-cmd --reload
下面用Navicat新建连接,即可
