windows noinstall安装配置mysql5.5 1.首先获取mysql5.5，下载社区版，免费。 ? mysql5.5的现在地址?http://dev.mysql.com/downloads/mysql/5.5.html#downloads ??mysql5.5_noinstall_32位的下载地址：http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.34

1.首先获取mysql5.5，下载社区版，免费。

? mysql5.5的现在地址?http://dev.mysql.com/downloads/mysql/5.5.html#downloads

??mysql5.5_noinstall_32位的下载地址：http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.34-win32.zip

? ?mysql5.5_noinstall_位的下载地址：http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.34-winx.zip

?

2.开始安装

? 把mysql-5.5.34-winx.zip解压缩到C盘，并把mysql-5.5.34-winx重命名mysql，复制my-medium.ini为my.ini，修改my.ini，在[mysqld]下面增加：??

basedir=C:/mysql
datadir=C:/mysql/data

?

?

? 把mysql加入环境变量，这一步可以不做，只是为了以后在任意路径下都可以登陆mysql。

??新增加环境变量：

MYSQL_HOME=C:\mysql

?修改PATH环境变量，在最前面增加，注意最后面的英文字符";"：

%MYSQL_HOME%\bin;

?3.安装服务

C:\mysql\bin>mysqld --install mysql --defaults-file="c:\mysql\my.ini"
Service successfully installed.

? ?如果需要删除mysql服务，命令如下：

C:\mysql\bin>mysqld -remove mysql
Service successfully removed.

?4.启动与停止

? 可以直接开始-》运行-》输入如下命令回车：

?

net start mysql

? 同样停止mysql服务，开始-》运行-》输入如下命令回车：

?

net stop mysql

?5.初始化数据库

? C:\>mysql -uroot -p 回车，要求输入密码，直接回车继续。

?

C:\>mysql -uroot -p
Enter password:

更改root的密码为root：

?

mysql> use mysql;#使用mysql这个数据库
Database changed
mysql> update user set password=password("root") where user="root";#更改root账号的密码为root
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0

mysql> flush privileges;#刷新权限
Query OK, 0 rows affected (0.00 sec)

? 退出并重新测试新密码：

?

mysql> exit #退出mysql
Bye

? 重新登陆：

?

C:\>mysql -uroot -p
Enter password: **** #输入新密码root

6.乱码问题

? ?登录mysql查看编码：

??SHOW VARIABLES LIKE 'character%';

? SHOW VARIABLES LIKE 'collation%';?

?

mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+--------------------------+
| Variable_name | Value |
+--------------------------+--------------------------+
| character_set_client | gbk |
| character_set_connection | gbk |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | gbk |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | C:\mysql\share\charsets\ |
+--------------------------+--------------------------+
8 rows in set (0.00 sec)

mysql> SHOW VARIABLES LIKE 'collation%';
+----------------------+-------------------+
| Variable_name | Value |
+----------------------+-------------------+
| collation_connection | gbk_chinese_ci |
| collation_database | latin1_swedish_ci |
| collation_server | latin1_swedish_ci |
+----------------------+-------------------+
3 rows in set (0.00 sec)

?

? ?在[client]下面增加：

? default-character-set = utf8

? 在[mysqld]下面增加：

? character_set_server = utf8

? collation-server=utf8_bin

? init_connect='SET NAMES utf8'

? 在[mysql]下面增加：

? default-character-set=utf8

? 修改完成后的my.ini文件如下：

# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# MySQL programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, see:
# http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# The following options will be passed to all MySQL clients
[client]
#password	= your_password
port	= 3306

# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.

# Replication Master Server (default)

log-bin=mysql-bin

# binary logging format - mixed recommended
binlog_format=mixed

# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id	= 1

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,
# MASTER_USER=, MASTER_PASSWORD= ;
#
# where you replace , ,  by quoted strings and
#  by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.5.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = 
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = 
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = 
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port =

??保存，然后重启mysql服务.重新登陆mysql，并查看编码：

?

mysql> SHOW VARIABLES LIKE 'character%';

| character_set_client | utf8 |
| character_set_connection | utf8 |

? 附带另一篇博文的内容：

? 客户端连接mysql出现 xxx.xxx.xxx.xxx is not allowed to connect to this MySQL server

??登陆mysql，并赋予远程连接权限：

? ? grant all privileges on *.* to root@'%' identified by 'root123' with grant option;?

? ? ? ?#1、此处'%'表示任何IP都可以访问，如果指定IP访问则这块把%换成IP地址即可.

? ? ? ?#2、后面的'root123'是IP地址远程连接mysql时root账号的密码，可以与localhost或127.0.0.1登陆时root的密码不一致。

? ? flush privileges; #刷新权限

mysql> grant all privileges on *.* to root@'%' identified by 'root123' with grant option;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

?

至此mysql5.5全部配置完毕。
