- 日理万妓 2021-12-19 14:49 251阅读 0赞

**背景：为了使用高版本的mysql，而又不删除原来低版本的mysql**

### 一、下载免安装版mysql ###

**下载地址：[https://dev.mysql.com/downloads/mysql/][https_dev.mysql.com_downloads_mysql]**

**[https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.16-winx64.zip][https_cdn.mysql.com_Downloads_MySQL-8.0_mysql-8.0.16-winx64.zip]**

### 二、指定安装目录 ###

**解压文件到指定目录(此处为E:\\，安装目录为E:\\mysql-8.0.16-winx64)**

[mysql]
    # 设置mysql客户端默认字符集
    default-character-set=utf8mb4
    [mysqld]
    #默认为3306，此处设置3307端口
    port = 3307
    # 将basedir设置为安装路径
    basedir=E:/mysql-8.0.16-winx64
    # 将datadir设置为数据目录的位置
    datadir=F:/important/MysqlDataStorage
    # 允许最大连接数
    max_connections=200
    # 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
    max_connect_errors=20
    # 服务端使用的字符集默认为8比特编码的latin1字符集
    character-set-server=utf8mb4
    # 创建新表时将使用的默认存储引擎
    default-storage-engine=INNODB
    # 忽略密码
    # skip-grant-tables

** 2. 根据配置的datadir创建相应的文件夹（F:\\important\\MysqlDataStorage）**
