大道浮屠诀---mysql5.7.28 for linux安装

环境：

redhat6.5

MySQL Community Server 5.7.28　　https://dev.mysql.com/downloads/mysql/5.7.html

 前提环境：关闭selinux

---

安装RMP包的具体操作如下：

1、如有mariadb,先卸载

rpm -qa |grep mariadb

rpm -qa |grep mysql

rpm -e --nodeps xxxxxx  （卸载查询到的rpm包）

2、安装新的mysql5.7.28，解压安装包

tar -xvf mysql-5.7.28-1.el6.x86_64.rpm-bundle.tar

 3、rpm安装(不是所有包必须安装，但必须按顺序安装)

rpm -ivh mysql-community-common-5.7.28-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.28-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.28-1.el6.x86_64.rpm
rpm -ivh mysql-community-client-5.7.28-1.el6.x86_64.rpm
rpm -ivh mysql-community-server-5.7.28-1.el6.x86_64.rpm　　　　# 注：linux 7版本会有报错  命令后加上参数[--nodeps --force]
rpm -ivh mysql-community-devel-5.7.28-1.el6.x86_64.rpm

4、安装完毕，数据库初始化

mysqld --initialize --user=mysql

5、查看临时生成的数据库密码

cat /var/log/mysqld.log

 6、启动mysql

service mysqld start

 7、登陆mysql数据库，并修改密码

mysql -uroot -p

set password = password('password');

---

至此安装完毕！

---

利用Navicat工具连接mysql(root用户)

mysql -uroot -p 进入数据库

use mysql

select host,user from user;

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

GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;

flush   privileges;
