1、安装环境
系统版本 | 内存 | 处理器内核总数 | 硬盘 | MySQL版本 |
---|---|---|---|---|
CentOS Linux release 7.2.1511 (Core) | 1G | 2 | 40G | 5.7.31 |
下载地址:https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.31-1.el7.x86_64.rpm-bundle.tar
2、检查卸载MySQL|mariadb
#检查
rpm -qa | grep mysql
rpm -qa | grep mariadb
#卸载
rpm -e --nodeps [mysql组件]
如下图:
3、解压安装包
tar -xvf mysql-5.7.31-1.el7.x86_64.rpm-bundle.tar
4、安装MySQL(按顺序执行)
rpm -ivh mysql-community-common-5.7.31-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.31-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.31-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.31-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.31-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.31-1.el7.x86_64.rpm
如下图:
5、配置默认字符集
-
/etc/my.cnf 文件,在[mysqld] 标签下添加
vim /etc/my.cnf [mysqld] init_connect='SET collation_connection = utf8_unicode_ci' init_connect='SET NAMES utf8' character-set-server=utf8 collation-server=utf8_unicode_ci skip-character-set-client-handshake
在最后一行添加
skip-grant-tables
调过密码验证 -
/etc/my.cnf.d/client.cnf 文件,在 [client] 标签下添加
vim /etc/my.cnf.d/client.cnf [client] default-character-set=utf8
-
/etc/my.cnf.d/mysql-clients.cnf 文件,在 [mysql] 标签下添加
vim /etc/my.cnf.d/mysql-clients.cnf [mysql] default-character-set=utf8
6、启动设置
-
启动MySQL
service mysqld start
-
以root账户登陆mysql,直接回车
mysql -u root -p
-
设置root账户密码
use mysql; update mysql.user set authentication_string=password('root') where user='root';
-
去掉
/etc/my.cnf
中的skip-grant-tables
,并重启MySQLservice mysqld restart
-
再次登录MySQL,设置远程主机登录
GRANT ALL PRIVILEGES ON *.* TO'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION; FLUSH PRIVILEGES ;
报错如下:
mysql> GRANT ALL PRIVILEGES ON *.* TO'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION; ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. mysql>
重置密码
alter user user() identified by "aaa@qq.com"; FLUSH PRIVILEGES ;
注意:测试远程连接的时候关闭防火墙,或开放3306端口
奇怪了,进行MySQL-5.7.31在线安装的时候就没出现过关于密码策略方面的问题,离线安装的时候却出现了。
