Linux下的 Mysql 8.0 yum 安装 并修改密码

1.MySQL版本：

mysql> select @@version;
+-----------+
| @@version |
+-----------+
| 8.0.18 |
+-----------+
1 row in set (0.00 sec)

2.Centos操作系统版本

[[email protected] /]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)　　　　

二、Mysql现在以及解压

1. 地址：https://downloads.mysql.com/archives/community/

2.linux中下载

1.在命令中输入这个语句，获取 mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar：

wget https://cdn.mysql.com/archives/mysql-8.0/mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar

2.解压：

tar -xvf mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar

-rw-r--r-- 1 root root 684851200 9月 23 15:36 mysql-8.0.18-1.el7.x86_64.rpm-bundle.tar
-rw-r--r-- 1 7155 31415 40104640 9月 23 15:19 mysql-community-client-8.0.18-1.el7.x86_64.rpm
-rw-r--r-- 1 7155 31415 611436 9月 23 15:20 mysql-community-common-8.0.18-1.el7.x86_64.rpm
-rw-r--r-- 1 7155 31415 6915400 9月 23 15:20 mysql-community-devel-8.0.18-1.el7.x86_64.rpm
-rw-r--r-- 1 7155 31415 23683600 9月 23 15:20 mysql-community-embedded-compat-8.0.18-1.el7.x86_64.rpm
-rw-r--r-- 1 7155 31415 3877664 9月 23 15:20 mysql-community-libs-8.0.18-1.el7.x86_64.rpm
-rw-r--r-- 1 7155 31415 1363968 9月 23 15:20 mysql-community-libs-compat-8.0.18-1.el7.x86_64.rpm
-rw-r--r-- 1 7155 31415 450282440 9月 23 15:21 mysql-community-server-8.0.18-1.el7.x86_64.rpm
-rw-r--r-- 1 7155 31415 158001648 9月 23 15:22 mysql-community-test-8.0.18-1.el7.x86_64.rpm

三、安装

1. 卸载系统自带的mariadb-lib

查看mariadb版本
rpm -qa|grep mariadb
mariadb-libs-5.5.56-2.el7.x86_64

卸载mariadb
rpm -e mariadb-libs-5.5.56-2.el7.x86_64 --nodeps

2.安装依赖环境

yum install -y openssl-devel.x86_64 openssl.x86_64
yum install -y libaio.x86_64 libaio-devel.x86_64
yum install -y perl.x86_64 perl-devel.x86_64
yum install -y perl-JSON.noarch
yum install -y autoconf
yum install -y wget
yum install -y net-tools

3.关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service

4.禁用selinux

vi /etc/selinux/config
将SELINUX=enforcing改为SELINUX=disabled
reboot 重启机器

5.安装

/**

必须按顺序装，防止出现未知的问题

*/

rpm -ivh mysql-community-common-8.0.18-1.el7.x86_64.rpm
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

--------------------------------------------------------------------------------

rpm -ivh mysql-community-libs-compat-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-embedded-compat-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-8.0.18-1.el7.x86_64.rpm
rpm -ivh mysql-community-test-8.0.18-1.el7.x86_64.rpm

--初始化数据库
mysqld --initialize --console
--目录授权，否则启动失败
chown -R mysql:mysql /var/lib/mysql/
--启动服务
systemctl start mysqld

6.登陆密码设置

//报错
ERROR 2003 (HY000): Can‘t connect to MySQL server on ‘localhost‘ (111)  ‘1）更改配置，此处可以跳过密码设置
vi /etc/my.cnf
#在mysqld模块下添加
skip-grant-tables// password 函数在MySQL8中位置，以下步骤未实现
2）重启服务：
systemctl restart mysqld
3） 按照传统改密码方式发现没有 password这个字段。
mysql> update user set password=password(‘123‘) where user=‘root‘;
ERROR 1054 (42S22): Unknown column ‘password‘ in ‘field list‘

网上查了一下据说5.7 版本password 字段改成authentication_string  password函数未知

mysql> update user set authentication_string=password(‘123‘) where user=‘root‘;
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 1


user 表的管理字段
