CentOS7用yum安装MySQL8.0 2209170054
CentOS7用yum安装MySQL8.0 2209170054
Ubuntu20.04安装MySQL很轻松, apt install mysql-server就搞定了
CentOS7安装MySQL很麻烦, 不能用yum直接安装, 要下载mysql官方的安装包或yum仓库配置,
apt安装的mysql不带validate_password组件
yum安装的mysql带validate_password组件,密码强度要求变态,注意可能以括号开头,是密码的一部分

MySQL的官方下载, 不但有安装包, 还有yum仓库配置包可选
- MySQL安装包的下载地址—https://dev.mysql.com/downloads/mysql/,
还有 - YUM仓库安装MySQL的配置包的下载地址—https://dev.mysql.com/downloads/repo/yum/
本次不使用安装包安装, 而是yum配置包配置yum后,用yum安装
点击打开YUM仓库安装MySQL的yum配置文件的下载地址—https://dev.mysql.com/downloads/repo/yum/
2018年06月, 下载到的是mysql80-community-release-el7-1.noarch.rpm 安装的是MySQL8.0.11
2018年12月, 下载到的是 mysql80-community-release-el7-1.noarch.rpm 安装的是MySQL8.0.13
2022年09月, 下载到的是 mysql80-community-release-el7-7.noarch.rpm 安装的是MySQL8.0.30
发文时,红框的链接为:https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm , 可以下载到 mysql80-community-release-el7-7.noarch.rpm 文件, 将会安装MySQL8.0.30版本
https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm
第一步,下载并使用mysql80-community-release-el7-7.noarch.rpm 配置yum
可以直接用yum下载并安装这个文件
sudo yum install -y https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm
也可以分步
- sudo yum install wget , 下载wget
- sudo wget -O https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm , 用wget来下载这个文件
- sudo rpm -ivh mysql80-community-release-el7-7.noarch.rpm , 用rpm安装这个文件
或者
sudo yum install mysql80-community-release-el7-7.noarch.rpm , 用yum安装这个文件
rpm安装的话,可以在wget下载时重命名,比如改名为 temp , 少打字
yum安装的话,不能去掉.rpm结尾的扩展名
第二步, 此时就能用yum安装新版MySQL了
sudo yum install -y mysql-server
或者
sudo yum install -y mysql-community-server.x86_64
效果一样
第三步, 启动mysqld服务
CentOS的mysql服务是mysqld , Ubuntu是mysql
- 启动CentOS7的MySQL8.0用的是
systemctl start mysqld - 启动Ubuntu20.04的MySQL8.0用的是
systemctl start mysql
sudo systemctl enable mysqld
sudo systemctl start mysqld
Ubuntu : systemctl enable mysql ; systemctl start mysql
CentOS: systemctl enable mysqld ; systemctl start mysqld
第四步, 查看生成的root变态密码, 用变态密码登录
Ubuntu20.04 下用apt安装的mysql8.0.30默认不带validate_password组件,可以使用空密码
CentOS7下用yum安装的mysql8.0.30带validate_password组件,默认要大小写字母数字特殊符号一起用,还有长度要求,体验很差
密码可能以括号开头结尾
查看生成的初始变态密码 grep 'temporary password' /var/log/mysqld.log;
grep 'temporary password' /var/log/mysqld.log;
例如
[root@VboxC7min2207 ~]# grep 'temporary password' /var/log/mysqld.log;
2022-09-16T19:14:48.584198Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: iB9tnxeshg>a
看到自动生成的初始变态密码是 : iB9tnxeshg>a
或者
awk -F': ' '/A temporary password is generated for/{print $2}' /var/log/mysqld.log
[root@VboxC7min2207 ~]# awk -F': ' '/A temporary password is generated for/{print $2}' /var/log/mysqld.log
)Bkisp%38gfy
看到自动生成的初始变态密码是 : )Bkisp%38gfy
用初始密码登录
手动输入密码
mysql -uroot -p
或者复制粘贴密码
用复制粘贴的话,因为有特殊字符,所以要加上单引号和双引号
并且-p和单双引号之间不能有空格
mysql -uroot -p')Bkisp%38gfy'
不加单或双引号复制粘贴的结果
[root@VboxC7min2207 ~]# grep 'temporary password' /var/log/mysqld.log;
2022-09-16T19:14:48.584198Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: iB9tnxeshg>a
[root@VboxC7min2207 ~]# mysql -uroot -piB9tnxeshg>a
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
[root@VboxC7min2207 ~]# mysql -uroot -p iB9tnxeshg>a
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
第五步, 登录后,必须修改密码才能执行其它操作
必须先更改为另一个变态密码, 可以不用记住它, 设好后, 降低密码强度, 或者卸载validate_password这个变态组件
设置密码方法1
ALTER USER root@localhost IDENTIFIED BY 'ABCDEFGhijklmn1234567!!!';
设置密码方法2
SET PASSWORD='ABCDEFGhijklmn1234567!!!';
第六步,修改初始密码后, 可以设置降低密码强度, 使用简单密码
降低密码强度要求的方法有
- 设置
validate_password的相关选项 - 卸载
validate_password
可选:降低 validate_password 组件对密码强度的要求
SET GLOBAL validate_password.policy=LOW;降低密码复杂度要求SET GLOBAL validate_password.mixed_case_count=0;最少大小写字符数SET GLOBAL validate_password.number_count=0;最少数字字符数SET GLOBAL validate_password.special_char_count=0;最少特殊字符数SET GLOBAL validate_password.check_user_name=OFF; 允许用户名和密码相同SET GLOBAL validate_password.length=0;设置密码最小长度, 要放到最后设置, 否则可能被其它值影响, 使其没法为0, 可能是4或者2
### 密码策略: 0或LOW是只检查长度 , 1或MEDIUM是检查长度数字字母特殊字符的个数 , 2或STRONG是比1多检查字典文件 ;
SET GLOBAL validate_password.policy=LOW;
### 最少大小写字符数
SET GLOBAL validate_password.mixed_case_count=0;
### 最少数字字符数
SET GLOBAL validate_password.number_count=0;
### 最少特殊字符数
SET GLOBAL validate_password.special_char_count=0;
### 是否允许密码包含正反用户名 , 取值ON/OFF
SET GLOBAL validate_password.check_user_name=OFF;
### 密码最小长度, 要放到最后设置, 否则可能被其它值影响, 使其没法为0, 可能是4或者2
SET GLOBAL validate_password.length=0;
### 查看 validate_password 的相关MySQL系统变量
SHOW VARIABLES LIKE '%validate_password%';
可选: 卸载 validate_password 组件
-
安装 validate_password 组件
INSTALL COMPONENT 'file://component_validate_password'; -
卸载 validate_password 卸载
UNINSTALL COMPONENT 'file://component_validate_password';
我选卸载 validate_password 插件
UNINSTALL COMPONENT 'file://component_validate_password';
然后就能设为空密码
ALTER USER root@localhost IDENTIFIED BY '';
或
SET PASSWORD='';
操作系统的root输入mysql就能直接登录
第七步, 创建远程用户,开放防火墙端口3306
创建远程用户
创建一个名为remote的远程用户, remote等效’remote’@‘%’
### 创建一个名为remote的远程用户, remote等效'remote'@'%'
CREATE USER remote IDENTIFIED BY '';
创建一个可以用 Navicat11 登录的远程用户
### 创建一个名为remote的远程用户, remote等效'remote'@'%', 使用mysql5.7旧版密码插件,方便使用Navicat11等登录
CREATE USER remote IDENTIFIED WITH mysql_native_password BY '';
赋予remote所有权限和权力传递的权限,并将root角色授予remote
GRANT ALL ON *.* TO 'remote'@'%' WITH GRANT OPTION; GRANT root@'localhost' TO remote; SET DEFAULT ROLE root@'localhost' TO remote; FLUSH PRIVILEGES;
开放 firewalld 防火墙的3306端口
sudo firewall-cmd --zone=public --permanent --add-port=3306/tcp ; sudo systemctl restart firewalld ;
用脚本安装
CentOS7一步安装MySQL8.0并且第一次登录
#!/bin/bash
### CentOS7一步安装MySQL8.0并且第一次登录
sudo yum install -y https://dev.mysql.com/get/mysql80-community-release-el7-7.noarch.rpm

MysqlFirstLoginCodeCommand="mysql -uroot -p"$MysqlInitialTemporaryPassword
echo $MysqlFirstLoginCodeCommand;$MysqlFirstLoginCodeCommand
CentOS7一步安装MySQL8.0并且将root@localhost免密

ALTER USER root@localhost IDENTIFIED BY 'ABCDEFGhijklmn1234567!!!';
### 密码策略: 0或LOW是只检查长度 , 1或MEDIUM是检查长度数字字母特殊字符的个数 , 2或STRONG是比1多检查字典文件 ;
SET GLOBAL validate_password.policy=LOW;

SET PASSWORD='';
exit
mysql -uroot

validate_password插件 和 validate_password组件
MySQL8.0官方参考手册—密码验证组件—6.4.3 The Password Validation Component
MySQL5.7官方参考手册—密码验证插件—6.4.3 The Password Validation Plugin
组件和插件
- MySQL5.7, 用的是 validate_password
插件 - MySQL8.0, 用的是 validate_password
组件
Ubuntu20.04下用apt安装的MySQL8.0默认没有使用validate_password 插件或组件
CentOS7下用MySQL官方yum仓库安装的MySQL8.0默认启用validate_password 组件
MySQL5.7的 validate_password 插件 在MySQL8.0中任然可以使用,但默认不使用,已过时,未来准备移除
| MySQL8.0的 validate_password 组件 | MySQL5.7 validate_password 插件 | 功能 | 取值 |
|---|---|---|---|
| validate_password.check_user_name | validate_password_check_user_name | 检查密码与用户名是否相同或相反 | ON/OFF |
| validate_password.dictionary_file | validate_password_dictionary_file | 检查密码与密码字典 | 字典文件路径 |
| validate_password.length | validate_password_length | 检查密码长度 | 0至正整数 |
| validate_password.mixed_case_count | validate_password_mixed_case_count | 检查密密码大小写字母总数 | 0至正整数 |
| validate_password.number_count | validate_password_number_count | 检查密密码数字字符总数 | 0至正整数 |
| validate_password.policy | validate_password_policy | 密码策略,检查密码复杂度 | 0、1、2 对应 LOW、MEDIUM、STRONG |
| validate_password.special_char_count | validate_password_special_char_count | 检查密码特殊字符的个数 | 0至正整数 |
可看到插件变量validate_password之后是下划线_ , 组件变量validate_password之后是点.
插件的变量是相对独立的, 组件的变量被统一在validate_password之下
validate_password.policy 和 validate_password_policy 的取值
| `validate_password.policy` 和 `validate_password_policy` 的取值效果 | |
|---|---|
| 取值 | 效果 |
| 0 或者 LOW | 只检查密码长度 |
| 1 或者 MEDIUM | 检查长度; 数字、小写/大写和特殊字符 |
| 2 或者 STRONG | 长度; 数字、小写/大写和特殊字符；字典文件 |
