MySql 5.7.17免安裝配置教程詳解
1、下載mysql-5.7.17-winx64.zip安裝包（鏈接：https://dev.mysql.com/downloads/mysql/）
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(gè)名為data的文件夾，用來(lái)存放數(shù)據(jù)
D:\DevelopTool\mysql-5.7.17-winx64\data
4、配置啟動(dòng)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(duì)路徑 # basedir=./.. basedir=D:\\DevelopTool\\mysql-5.7.11-winx64 # datadir 為用來(lái)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(hào) 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(huì)初始化 data 目錄，在執(zhí)行此命令前請(qǐng)先把data目錄下的所有文件先刪除，否則會(huì)失敗
可以選擇用 --initialize-insecure 或者 --initialize 來(lái)初始化，--initialize-insecure 初始化root密碼為空，如果用 --initialize來(lái)初始化，會(huì)產(chǎn)生一個(gè)隨機(jī)密碼
執(zhí)行成功后，在data目錄下會(huì)生成mysql，perofrmance_schema，sys等目錄文件
6、安裝和啟動(dòng)mysql服務(wù)
#安裝服務(wù) mysqld -install #啟動(dòng)服務(wù) net start mysql #進(jìn)入mysql mysql -u root -p #移除mysql mysqld -remove
