MySQL 5.7.15 ZIP版本配置方案

MySQL 官方配置参数查询

一、下载 MySQL 5.7.15 zip 安装包

本机以 Windows10 64 位系统为例
进入 Oracel 官网，选择 MySQL Windows (x86, 64-bit), ZIP Archive 下载包
点此下载

---

二、解压安装包

将MySQL数据库解压至目录 D:\Program Files\mysql-5.7.15-winx64
将 D:\Program Files\mysql-5.7.15-winx64\bin 添加至环境变量 Path 中

---

三、创建一个空文件夹，命名为“data”，用来存放数据

本机创建在 D:\Program Files\mysql-5.7.15-winx64 目录下，所以最后会看到D:\Program Files\mysql-5.7.15-winx64\data，此文件夹后面会有用到

---

四、配置启动配置文件

把 D:\Program Files\mysql-5.7.15-winx64\my-default.ini 文件复制一份，重新命名为 my.ini，修改里面的几个参数， 配置文件如下：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/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.

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
character-set-server=utf8

# 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:\Program Files\mysql-5.7.15-winx64
datadir = D:\Program Files\mysql-5.7.15-winx64\data
port = 3306
max_connections=200
# 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

explicit_defaults_for_timestamp=true
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

---

五、初始化数据目录

• 管理员身份打开 CMD;
• 当前路径定位到 D:\Program Files\mysql-5.7.15-winx64\bin
• 按照mysql官方文档给出的步骤还有一步 Selecting a MySQL Server Type，就是选择用 mysqld 还是 mysqld-debug.

一般使用如下命令：

mysqld –defaults-file=”D:\Program Files\mysql-5.7.15-winx64\my.ini” –initialize-insecure

注：
- 这个命令很重要，它会初始化 data 目录，在执行此命令前请先把 data 目录下的所有文件先删除，否则会失败；
- 可以选择用 –initialize-insecure 或者 –initialize 来初始化，–initialize-insecure 初始化 root 密码为空，如果用 –initialize 来初始化，会产生一个随机密码；
- 执行成功后你会在 data 目录 下看到 mysql，perofrmance_schema，sys 目录，同时还会有一些文件。

---

六、安装 mysql 服务

mysqld -install
mysqld -remove （出问题重新配置前需要卸载服务）

---

七、启动 mysql 服务、添加初始密码

net start mysql
mysqladmin -u root password 123456
mysql -u root -p

---

八、设置默认编码

先确保my.ini添加以下代码
~~~
[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
default-character-set=utf8 或者 character-set-server=utf8
~~~

通过命令查看数据库当前编码

mysql -u root -p
show variables like ‘character%’;

如果不是以下编码，则设置编码

+————————–+——————————————————+
| Variable_name | Value |
+————————–+——————————————————+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | D:\Program Files\mysql-5.7.15-winx64\share\charsets\ |
+————————–+——————————————————+

设置编码：

SET character_set_client = utf8;
SET character_set_connection = utf8;
SET character_set_database = utf8;
SET character_set_results = utf8;
SET character_set_server = utf8;

• character_set_client为客户端编码方式；
• character_set_connection为建立连接使用的编码；
• character_set_database数据库的编码；
• character_set_results结果集的编码；
• character_set_server数据库服务器的编码；

---

九、mysql 开启远程连接

grant all privileges on *.* to ‘root’@’%’ identified by ‘123456’ with grant option;

后记：
如果中途有什么步骤失败，一定要执行 mysql 移除命令，然后删除 data 目录下的所有文件，然后删除服务 mysqld -remove
特别提醒：5.7 和 5.6 不太相同，要自己初始化数据 data 目录，不然启动不会成功

---

十、后记

mysql 安装完后可能会用到的语句

alter user ‘root’@’localhost’ identified by ‘123’;
create database victor;
create user ‘victor’@’localhost’ identified by ‘victor@123’;
flush privileges;
creaet user ‘victorremote’@’%’ identified by ‘victorremote@123’;
flush privileges;
grant all on victor.* to ‘victor’@’localhost’ identified by ‘victor@123’;
flush privileges;
grant all on victor.* to ‘victorremote’@’%’ identified by ‘victorremote@123’;
flush privileges;

#

show variables like ‘collation_%’;
show variables like ‘character_set_%’;
set collation_connection=utf8_general_ci;

#
