+# 在Linux上安装MySQL
+
+## 1、查看系统版本号
+
+```bash
+cat /proc/version
+Linux version 3.10.0-1062.18.1.el7.x86_64
+(mockbuild@kbuilder.bsys.centos.org) 
+(gcc version 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) ) 
+#1 SMP Tue Mar 17 23:49:17 UTC 2020
+```
+
+## 2、下载MySQL
+
+MySQL Community Server 下载地址：
+
+[https://dev.mysql.com/downloads/mysql/](https://dev.mysql.com/downloads/mysql/)
+
+
+选项
+```bash
+# 选择红帽企业版
+Operating System: Red Hat Enterprise Linux / Oracle Linux
+
+# 系统版本是7，所以选择7版本
+OS Version: Red Hat Enterprise Linux 7 / Oracle Linux 7 (x86, 64-bit)
+```
+
+下载：RPM Bundle
+
+```bash
+wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.29-1.el7.x86_64.rpm-bundle.tar
+```
+
+## 3、创建目录并解压
+
+```bash
+$ mkdir mysql-8.0.29
+
+$ tar -xvf mysql-8.0.29-1.el7.x86_64.rpm-bundle.tar -C mysql-8.0.29
+```
+
+## 4、安装MySQL
+
+```bash
+cd mysql-8.0.29
+
+# 查看解压后的内容
+$ ls
+mysql-community-client-8.0.29-1.el7.x86_64.rpm
+mysql-community-client-plugins-8.0.29-1.el7.x86_64.rpm
+mysql-community-common-8.0.29-1.el7.x86_64.rpm
+mysql-community-debuginfo-8.0.29-1.el7.x86_64.rpm
+mysql-community-devel-8.0.29-1.el7.x86_64.rpm
+mysql-community-embedded-compat-8.0.29-1.el7.x86_64.rpm
+mysql-community-icu-data-files-8.0.29-1.el7.x86_64.rpm
+mysql-community-libs-8.0.29-1.el7.x86_64.rpm
+mysql-community-libs-compat-8.0.29-1.el7.x86_64.rpm
+mysql-community-server-8.0.29-1.el7.x86_64.rpm
+mysql-community-server-debug-8.0.29-1.el7.x86_64.rpm
+mysql-community-test-8.0.29-1.el7.x86_64.rpm
+
+# 按照顺序进行逐个安装
+rpm -ivh mysql-community-common-8.0.29-1.el7.x86_64.rpm
+
+rpm -ivh mysql-community-client-plugins-8.0.29-1.el7.x86_64.rpm
+
+# 依赖检测失败：mariadb-libs 被 mysql-community-libs-8.0.29-1.el7.x86_64 取代
+# yum -y remove mariadb-libs
+rpm -ivh mysql-community-libs-8.0.29-1.el7.x86_64.rpm
+
+rpm -ivh mysql-community-libs-compat-8.0.29-1.el7.x86_64.rpm
+
+# 依赖检测失败：pkgconfig(openssl) 被 mysql-community-devel-8.0.29-1.el7.x86_64 需要
+# yum -y install openssl-devel
+rpm -ivh mysql-community-devel-8.0.29-1.el7.x86_64.rpm
+
+rpm -ivh mysql-community-client-8.0.29-1.el7.x86_64.rpm
+
+rpm -ivh mysql-community-icu-data-files-8.0.29-1.el7.x86_64.rpm
+
+# 依赖检测失败：libaio.so.1()(64bit) 被 mysql-community-server-8.0.29-1.el7.x86_64 需要
+# yum -y install libaio
+rpm -ivh mysql-community-server-8.0.29-1.el7.x86_64.rpm
+```
+
+## 5、启动MySQL服务
+
+```bash
+systemctl start mysqld
+
+systemctl restart mysqld
+
+systemctl stop mysqld
+
+systemctl status mysqld
+```
+
+## 6、查看默认密码
+
+MySQL会自动生成默认的root密码
+
+```
+grep 'temporary password' /var/log/mysqld.log
+```
+
+## 7、修改root密码
+
+登录MySQL客户端
+
+```bash
+mysql -u root -p
+```
+
+修改root密码
+```sql
+-- 先设置一个符合要求的随机的密码
+SET PASSWORD FOR 'root'@'localhost' TO RANDOM;
+
+-- 查看密码校验参数
+show variables like 'validate_password%';
++--------------------------------------+--------+
+| Variable_name                        | Value  |
++--------------------------------------+--------+
+| validate_password.check_user_name    | ON     |
+| validate_password.dictionary_file    |        |
+| validate_password.length             | 8      |
+| validate_password.mixed_case_count   | 1      |
+| validate_password.number_count       | 1      |
+| validate_password.policy             | MEDIUM |
+| validate_password.special_char_count | 1      |
++--------------------------------------+--------+
+7 rows in set (0.01 sec)
+
+-- 修改密码复杂度限制参数
+set global validate_password.policy = 0;
+set global validate_password.length = 6;
+
+-- 修改密码
+alter user 'root'@'localhost' identified by '123456';
+
+-- 退出
+exit
+```
+
+再次使用自定义密码登录
+
+## 8、创建用户
+
+默认只能在localhost访问，使用`%`可以所有主机远程访问
+
+```sql
+create user 'root'@'%' identified with mysql_native_password by '123456';
+
+-- 创建用户，并设置随机密码
+create user 'user'@'%' IDENTIFIED BY RANDOM PASSWORD;
+
+-- 修改用户密码
+ALTER USER 'user'@'%' IDENTIFIED BY RANDOM PASSWORD;
+
+
+```
+
+## 9、分配权限
+
+```sql
+-- 分配所有权限
+grant all on *.* to 'root'@'%';
+```
