# MySQL安装方式汇总
# Windows环境
# MySQL8.0 zip安装方式
# 下载并解压
# 初始化配置文件
1.bin同级目录新建my.ini文件,复制配置内容
[mysqld]
# 设置时区为东八区
default-time-zone='+08:00'
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=D:\mysql-8.0.27-winx64
# 设置mysql数据库的数据的存放目录
datadir=D:\mysql-8.0.27-winx64\data
# 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=10
# 服务端使用的字符集默认为UTF8
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
# 默认使用“mysql_native_password”插件认证
default_authentication_plugin=mysql_native_password
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[client]
# 设置mysql客户端连接服务端时默认使用的端口
port=3306
default-character-set=utf8
2.修改basedir
3.修改datadir
# 初始化数据库
1.管理员打卡cmd,进入bin目录
2.生成随机密码方式
mysqld --initialize --console
会得到一串临时密码,要保存!!!
3.不生成密码
mysqld --initialize--insecure
# 安装mysql服务
1.输入命令
mysqld --install [MySQL3307]
默认名称是MySQL,
2.启动服务器
net start MySQL3307
3.关闭服务器
net stop MySQL3307
4.删除服务
SC DELETE MySQL3307
或者
mysqld --remove
# 进入mysql并修改密码
进入mysql
mysql -u root -p
修改密码
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密码';
# MySQL5.7 zip安装
[mysql]
# 设置mysql客户端默认字符集
default-character-set = utf8
[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
# 设置mysql的安装目录
basedir = D:\path-to-mysql
# 设置mysql数据库的数据的存放目录
datadir = D:\path-to-mysql\data
#设置3306端口
port = 3306
# server_id = .....
# 允许最大连接数
max_connections = 200
# 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 = utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine = INNODB
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
# wait_timeout = 28800
需要保存为ANSI格式,其他操作步骤一样
# Linux环境
# debian系统
# 准备安装包
官网下载Mysql Community Server 8.0.x Debian Linux系统
Mysql APT Repository
# 安装MYSQL
