mysql免安装方法

在官网上下载了个mysql-installer-community-5.6.27.0.msi，需要安装环境，检测未通过，很麻烦。之后网上查了资料之后直接下载了个压缩包mysql-5.6.27-winx64.zip。解压之后直接修改配置文件即可使用，不用安装那么麻烦。

步骤：

1.解压，我的路径为：E:\Program Files (x86)\mysql\mysql-5.6.27-winx64

2.找到该目录下以my-default.ini配置文件修改为：

# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/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 % of total RAM for dedicated server, else %.
  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.
  #mysql根目录
  basedir = "E:\Program Files (x86)\mysql\mysql-5.6.27-winx64"
  #数据库文件存放目录
  datadir = "E:\Program Files (x86)\mysql\mysql-5.6.27-winx64\data"
# port = ..... 端口默认3306
# server_id = .....  服务实例的唯一标识

# 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
#服务端编码方式
character-set-server=utf8
 [client]
 #客户端编码方式，最好和服务端保存一致
 loose-default-character-set = utf8
 [WinMySQLadmin]
 Server = "E:\Program Files (x86)\mysql\mysql-5.6.27-winx64\bin\mysqld.exe"

3.注册Mysql服务

　　开始——运行——cmd，然后cd到mysql安装目录的bin下面，我的目录就是“E:\Program Files（86）\mysql\mysql-5.6.22-win32\bin”，然后执行mysqld -install,提示服务安装成功！运行services.msc一看，确实有一个名为MySQL的服务了，启动它。

切记应以管理员身份运行，不然会报denied。
