mysqlがwindowsサービスで再起動すると立ち上がらなくなる

使用環境

win7 32bit
myslq 5.7

行った手順

①インストール後、環境変数にbinのパスを追記 ;C:\Program Files\MySQL\MySQL Server 5.7\bin
②cmdでmysqlにmysql -u root -p でログイン確認
③timezone_posixをcmdに貼り付けタイムゾーン設定
⑤my.iniのSERVER SECTIONにdefault-time-zone = 'Japan'を追記
④windowsサービスでmysql57を一度停止して、再度開始すると、状態 "開始中"になりmysqlへ接続出来なくなる            

⑤でのエラーコード

ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)

# Other default tuning values
# MySQL Server Instance Configuration File
# ----------------------------------------------------------------------
# Generated by the MySQL Server Instance Configuration Wizard
#
#
# Installation Instructions
# ----------------------------------------------------------------------
#
# On Linux you can copy this file to /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options
# (@localstatedir@ for this installation) or to
# ~/.my.cnf to set user-specific options.
#
# On Windows you should keep this file in the installation directory 
# of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
# make sure the server reads the config file use the startup option 
# "--defaults-file". 
#
# To run the server from the command line, execute this in a 
# command line shell, e.g.
# mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
#
# To install the server as a Windows service manually, execute this in a 
# command line shell, e.g.
# mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
#
# And then execute this in a command line shell to start the server, e.g.
# net start MySQLXY
#
#
# Guidelines for editing this file
# ----------------------------------------------------------------------
#
# In this file, you can use all long options that the program supports.
# If you want to know the options a program supports, start the program
# with the "--help" option.
#
# More detailed information about the individual options can also be
# found in the manual.
#
# For advice on how to change settings please see
# https://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
#
#
# CLIENT SECTION
# ----------------------------------------------------------------------
#
# The following options will be read by MySQL client applications.
# Note that only client applications shipped by MySQL are guaranteed
# to read this section. If you want your own MySQL client program to
# honor these values, you need to specify it as an option during the
# MySQL client library initialization.

# Specifies the base name to use for binary log files. With binary logging
# enabled, the server logs all statements that change data to the binary
# log, which is used for backup and replication.

# ***** Group Replication Related *****
# Sets the binary logging format, and can be any one of STATEMENT, ROW,
# or MIXED. ROW is suggested for Group Replication.

# ***** Group Replication Related *****
# Causes the master to write a checksum for each event in the binary log.
# binlog_checksum supports the values NONE (disabled) and CRC32.
# The default is CRC32. When disabled (value NONE), the server verifies
# that it is writing only complete events to the binary log by writing
# and checking the event length (rather than a checksum) for each event.
# NONE must be used with Group Replication.

# ***** Group Replication Related *****
# The base name for the relay log. The server creates relay log files in

# index file. Relay logs increase speed by using load-balancing between disks.

# ***** Group Replication Related *****
# Specifies the server ID. For servers that are used in a replication topology,
# you must specify a unique server ID for each replication server, in the

# from every other ID in use by any other replication master or slave.

# register itself with the master.

# ***** Group Replication Related *****
# The TCP/IP port number for connecting to the slave, to be reported to the master during

# ***** Group Replication Related *****
# This option specifies whether global transaction identifiers (GTIDs) are
# used to identify transactions. ON must be used with Group Replication.

# ***** Group Replication Related *****
# When enabled, the server enforces GTID consistency by allowing execution of
# only statements that can be safely logged using a GTID. You must set this
# option to ON before enabling GTID based replication.
# enforce_gtid_consistency

# ***** Group Replication Related *****
# Whether updates received by a slave server from a master server should be
# logged to the slave's own binary log. Binary logging must be enabled on
# the slave for this variable to have any effect. ON must be used with
# Group Replication.

windowsサービスでmysql57を再起動した後接続できなくなります。
mysql自体が立ち上がってないようですので、iniファイルに何か問題がないかと睨めっこしています・・・
是非お力添えをお願いしたいですm(__)m
