Windows 10 下mysql 安裝后無法啟動問題

安裝過程：

1. 官網下載5.15.7， http://dev.mysql.com/downloads/， 選擇開源社區版：MySQL Community Server (GPL)

2. 我解壓后放在 E:\mysql\5.7.15\ 下面

3. 將E:\mysql\5.7.15\bin加入系統path

4. 安裝mysql服務: mysqld --install

5. 編輯E:\mysql\5.7.15\my.ini文件

# 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]

basedir = E:/mysql/5.7.15
datadir = E:/mysql/data
port = 3306

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 

6. 用管理員身份打開cmd命令窗口

7. 初始化mysql: mysqld --initialize

8. 啟動mysql服務： net start mysql

====================================================================

遇到的問題：

問題1： 

E:\mysql\5.7.15>net start mysql
MySQL 服務正在啟動 .
MySQL 服務無法啟動。

服務沒有報告任何錯誤。

請鍵入 NET HELPMSG 3534 以獲得更多的幫助。


E:\mysql\5.7.15>net helpmsg 3534

服務沒有報告任何錯誤。

問題2： 

這個錯誤沒有仍和日志記錄，原因是my.ini中datadir所設定的目錄不存在，路徑分隔符需要采用linux格式“/”, 而不是“\"

如果mysql找不到這個data目錄, 那么初始化會出錯：

E:\mysql\5.7.15\bin>mysqld --initialize
mysqld: Can't create directory 'E:\myusql\data\' (Errcode: 2 - No such file or directory)

問題3： data目錄非空，也會初始化也會出錯：

E:\mysql\5.7.15\bin>mysqld --initialize
