0、环境 本文操作系统: CentOS 7.2.1511 x86_64 1、卸载系统自带的 mariadb-lib [root@centos-linux ~]# rpm -qa|grep mariadb mariadb-libs-5.5.44-2.el7.centos.x86_64 [root@centos-linux ~]# rpm -e mariadb-libs-5.5.44-2.el7.centos.x86_64 --nodeps 2、下载 rpm 安装包 去官网找到最新的 rpm 集合包。现在最新的是 mysql-5.7.13-1.el7.x86_64.rpm-bundle.tar 复制代码 代码如下: [root@centos-linux ~]# wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.13-1.el7.x86_64.rpm-bundle.tar 然后解压 [root@centos-linux ~]# ls mysql-5.7.13-1.el7.x86_64.rpm-bundle.tar [root@centos-linux ~]# tar xvf mysql-5.7.13-1.el7.x86_64.rpm-bundle.tar mysql-community-test-5.7.13-1.el7.x86_64.rpm mysql-community-embedded-5.7.13-1.el7.x86_64.rpm mysql-community-embedded-compat-5.7.13-1.el7.x86_64.rpm mysql-community-server-5.7.13-1.el7.x86_64.rpm mysql-community-client-5.7.13-1.el7.x86_64.rpm mysql-community-common-5.7.13-1.el7.x86_64.rpm mysql-community-server-minimal-5.7.13-1.el7.x86_64.rpm mysql-community-embedded-devel-5.7.13-1.el7.x86_64.rpm mysql-community-devel-5.7.13-1.el7.x86_64.rpm mysql-community-libs-compat-5.7.13-1.el7.x86_64.rpm mysql-community-libs-5.7.13-1.el7.x86_64.rpm mysql-community-minimal-debuginfo-5.7.13-1.el7.x86_64.rpm 3、安装 [root@centos-linux ~]# rpm -ivh mysql-community-common-5.7.13-1.el7.x86_64.rpm [root@centos-linux ~]# rpm -ivh mysql-community-libs-5.7.13-1.el7.x86_64.rpm [root@centos-linux ~]# rpm -ivh mysql-community-client-5.7.13-1.el7.x86_64.rpm [root@centos-linux ~]# rpm -ivh mysql-community-server-5.7.13-1.el7.x86_64.rpm 4、数据库初始化 在 *nix 系统中，为了保证数据库目录为与文件的所有者为 mysql 登陆用户，如果你是以 root 身份运行 mysql 服务，需要执行下面的命令初始化 上图里的最后一行则给出了生成的密码，现在就可以启动数据库了，然后使用上面的密码登陆。 [root@centos-linux ~]# systemctl start mysqld [root@centos-linux ~]# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.13 Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql> 5、修改 root 密码 该密码被标记为过期了，如果想正常使用还需要修改密码 mysql> show databases; ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. 以前的 password()函数将会被抛弃，官方建议使用下面的命令来修改密码 mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password'; 同时，如果你设置的密码过于简单也会报错。 mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123'; ERROR 1819 (HY000): Your password does not satisfy the current policy requirements 具体关于设置密码的规则，可以看这一篇文章。 以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持极客世界。 |
