安装mysql 8.0.17并配置远程访问的方法

一、安装前准备

查看数据库版本命令： mysql --version

mysql-community-common-8.0.17-1.el7.x86_64.rpmmysql-community-libs-8.0.17-1.el7.x86_64.rpmmysql-community-client-8.0.17-1.el7.x86_64.rpmmysql-community-server-8.0.17-1.el7.x86_64.rpm

依次安装上述RPM包，前后安装包为依赖关系。

# rpm -ivh mysql-community-common-8.0.17-1.el7.x86_64.rpm# rpm -ivh mysql-community-libs-8.0.17-1.el7.x86_64.rpm# rpm -ivh mysql-community-client-8.0.17-1.el7.x86_64.rpm# rpm -ivh mysql-community-server-8.0.17-1.el7.x86_64.rpm

mysql 8.0版本的初始密码默认非空，安装时自动生成，存储在/var/log/mysqld.logzhon中。

# rpm -ivh mysql-community-common-8.0.17-1.el7.x86_64.rpm# rpm -ivh mysql-community-libs-8.0.17-1.el7.x86_64.rpm# rpm -ivh mysql-community-client-8.0.17-1.el7.x86_64.rpm# rpm -ivh mysql-community-server-8.0.17-1.el7.x86_64.rpm

修改密码默认有安全性要求，对密码复杂度有控制。

mysql> alter user 'root'@'localhost' identified by 'redhat';ERROR 1819 (HY000): Your password does not satisfy the current policy requirementsmysql> alter user 'root'@'localhost' identified by '1qaz!QAZ';Query OK, 0 rows affected (0.15 sec)mysql> flush privileges;Query OK, 0 rows affected (0.01 sec)

mysql> show databases;mysql> use mysql;mysql> select user,host,plugin from user;

mysql> create user 'wangwang'@'%' identified by '1qaz!QAZ';Query OK, 0 rows affected (0.08 sec)mysql> grant all on *.* to 'wangwang'@'%';Query OK, 0 rows affected (0.12 sec)mysql> select user,host,plugin from user;

七、修改加密方式

修改加密规则

mysql> alter user 'wangwang'@'%' identified by '1qaz!QAZ' password expire never; Query OK, 0 rows affected (0.17 sec)

mysql> alter user 'wangwang'@'%' identified with mysql_native_password by '1qaz!QAZ';Query OK, 0 rows affected (0.04 sec)

mysql> flush privileges;Query OK, 0 rows affected (0.05 sec)

mysql> select user,host,plugin from user;

可以使用Navicat进行测试。
