port = 3306
# server_id = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.

0X07 回到CMD窗口，執行命令。
0X08 提示安裝拒絕，這時使用管理員身份運行命令窗口。再從新執行install命令
0X09 此時mysql5.7已經安裝成功，使用net start mysql 嘗試啟動服務（管理員模式下能夠正常啟動，普通權限無法啟動）
0X0A 嘗試再php工具箱中啟動或停止mysql服務（此時PHP工具箱無法啟動mysql服務。）
0X0B 在管理員模式下執行
0X0C 回到PHP工具箱 點擊重啟，此時mysql服務能夠正確的被啟動。
數據恢復
0X01 回到之前的MySQL_BAK目錄下賦值data中的內容到新的MySQL的目錄下，同戶名文件選擇跳過覆蓋。
0X02 通過MYSQL管理工具登陸MYSQL
賬號密碼均為root，此時回1045無法登陸
0X03 由於MYSQL安裝過程中密碼是水機產生，所以我們需要通過日志來查看密碼。
打開MYSQL/data目錄下的.err文件 查找並復制密碼，使用此密碼登陸mysql，並修改設置為自己的密碼。
0X04 此時登陸mysql
