針對之前安裝mysql的筆記進行了總結，分享給大家。
版本：MySQL-5.7.16-winx64
平台：Windows 7 x64
1、進入mysql主目錄（建議將其移到C或D盤的根目錄，並改名為mysql)
2、配置path環境變量（如D:\JAVA\mysql）添加到環境變量中。
3、mysql主目錄下的my-default.ini文件改名為my.ini，最簡單配置如下
# 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 = D:\JAVA\mysql datadir = D:\JAVA\mysql\data port = 3306 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 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
如下圖所示：
上圖可見，mysql沒有data目錄，接下來我們需要初始化data目錄
cmd下進入bin目錄
4、運行：mysqld --initialize
5、安裝mysql mysqld install mysql --defaults-file="D:\JAVA\mysql\my.ini"
6、啟動mysql net start mysql
後記：
在初始化時如果加上 –initial-insecure，則會創建空密碼的 root@localhost 賬號，否則會創建帶密碼的 root@localhost 賬號
密碼保存在：data文件夾下的*.err文件中
