MysqL应用1、下载MysqL-5.7.17-winx64.zip安装包(链接：https://dev.MysqL.com/downloads/MysqL/)
MysqL应用2、解压安装包.
MysqL应用D:\DevelopTool\MysqL-5.7.17-winx64 #解压目录
MysqL应用3、在解压目录下创建一个名为data的文件夹,用来存放数据
MysqL应用D:\DevelopTool\MysqL-5.7.17-winx64\data
MysqL应用 把 D:\DevelopTool\MysqL-5.7.17-winx64\my-default.ini 文件copy一份,重新命名为 my.ini,修改里面的参数,如下：
MysqL应用 # 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 为安装文件解压后的目录 ｜ basedir和datadir 可以使用相对路径 # basedir=./.. basedir=D:\\DevelopTool\\MysqL-5.7.11-winx64 # datadir 为用来存放数据的目录 # datadir=./../data datadir=D:\\DevelopTool\\MysqL-5.7.11-winx64\\data # port 为端口号 port=3306 # mar_connections为最大连接数 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
MysqL应用 5、初始化数据目录
MysqL应用它会初始化 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
MysqL应用可以选择用 --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
MysqL应用 执行成功后,在data目录下会生成MysqL,perofrmance_schema,sys等目录文件
MysqL应用 #安装服务 MysqLd -install #启动服务 net start MysqL #进入MysqL MysqL -u root -p #移除MysqL MysqLd -remove
