总结：MySQL安装和部署

一、下载：

1、MySQL8.0 For Windows zip包下载地址：https://dev.mysql.com/downloads/file/?id=476233

进入页面后可以不登录。后点击底部“No thanks, just start my download.”即可开始下载。

2、或直接下载：https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.11-winx64.zip

 

二、安装

1、设置my.ini初始化文件

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[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.

basedir=D:\Mysql\mysql-5.6.39-winx64

datadir=D:\Mysql\mysql-5.6.39-winx64\data 
# port = .....
# server_id = .....

# 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 

2、执行命令：

mysqld --install MySQL --defaults-file="D:\Mysqlmysql-5.6.39-winx64\my.ini"

MySQL为自定义服务名

3、启动命令：

net start MySQL

net stop MySQL

注意：用管理员方式运行cmd.exe

4、执行初始化

mysqld --initialize --console

注意：

8.0需要记住默认密码

5.6默认密码为空

5、登录

mysql -u root -P3306 -p 123456

端口号：3306

密码：123456

三、Navicat For MySql 可视化工具

默认配置远程无法访问，需要修改mysql中的ues表

设置：update user set host = '%' where user = 'root';

到此为止Mysql基本配置就已经搭建完成！

 

 

远程访问常见问题：

错误信息：2003 -Can't connect to MySQL server on “192.168.1.55” （10060）

排查过程：ip是否写对，端口号是否被防火墙屏蔽（防火墙添加入栈规则端口号）

 

错误信息：1130-host is not allowed MySQL不允许从远程访问的方法

mysql -u root -p

mysql>use mysql;

mysql>select 'host' from user where user='root';

mysql>update user set host = '%' where user ='root';

mysql>flush privileges;

mysql>select 'host'   from user where user='root';
