詳細(xì)說明MySql 5.7.17免安裝設(shè)置圖文說明教程的示例代碼

1、下載mysql-5.7.17-winx64.zip安裝包

2、解壓安裝包。

D:\DevelopTool\mysql-5.7.17-winx64 #解壓目錄

3、在解壓目錄下創(chuàng)建一個名為data的文件夾，用來存放數(shù)據(jù)

D:\DevelopTool\mysql-5.7.17-winx64\data

4、配置啟動文件

　　把 D:\DevelopTool\mysql-5.7.17-winx64\my-default.ini 文件copy一份，重新命名為 my.ini ，修改里面的參數(shù)，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.
[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 = .....
# datadir = .....
# port = .....
# server_id = .....
#########################
# basedir 為安裝文件解壓后的目錄 ｜ basedir和datadir 可以使用相對路徑
# basedir=./..
basedir=D:\\DevelopTool\\mysql-5.7.11-winx64
# datadir 為用來存放數(shù)據(jù)的目錄
# datadir=./../data
datadir=D:\\DevelopTool\\mysql-5.7.11-winx64\\data
# port 為端口號
port=3306
# mar_connections為最大連接數(shù)
max_connections=20
character_set_server=utf8
# 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

5、初始化數(shù)據(jù)目錄

mysqld --defaults-file="D:\DevelopTool\mysql-5.7.17-winx64\my.ini" --initialize-insecure

它會初始化 data 目錄，在執(zhí)行此命令前請先把data目錄下的所有文件先刪除，否則會失敗

可以選擇用 --initialize-insecure 或者 --initialize 來初始化，--initialize-insecure 初始化root密碼為空，如果用 --initialize來初始化，會產(chǎn)生一個隨機(jī)密碼

　　執(zhí)行成功后，在data目錄下會生成mysql，perofrmance_schema，sys等目錄文件

6、安裝和啟動mysql服務(wù)

#安裝服務(wù)
mysqld -install
#啟動服務(wù)
net start mysql
#進(jìn)入mysql
mysql -u root -p
#移除mysql
mysqld -remove
