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-win32.zip

   mysql5.5_noinstall_64位的下载地址：http://cdn.mysql.com/Downloads/MySQL-5.5/mysql-5.5.34-winx64.zip

 

2.开始安装

  把mysql-5.5.34-winx64.zip解压缩到C盘，并把mysql-5.5.34-winx64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

  登陆成功。

 

 

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)

 为了防止出现乱码，修改数据库编码为UTF-8，

 

   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 - 64M) 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
socket		= /tmp/mysql.sock
default-character-set = utf8

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
port		= 3306
socket		= /tmp/mysql.sock
skip-external-locking
key_buffer_size = 16M
max_allowed_packet = 1M
table_open_cache = 64
sort_buffer_size = 512K

read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M

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

character_set_server = utf8
collation-server=utf8_bin
init_connect='SET NAMES utf8'

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# 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.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
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=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', 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     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended
#log-bin=mysql-bin

# Uncomment the following if you are using InnoDB tables
#innodb_data_home_dir = C:\\mysql\\data\\
#innodb_data_file_path = ibdata1:10M:autoextend
#innodb_log_group_home_dir = C:\\mysql\\data\\
# You can set .._buffer_pool_size up to 50 - 80 %

#innodb_buffer_pool_size = 16M
#innodb_additional_mem_pool_size = 2M
# Set .._log_file_size to 25 % of buffer pool size
#innodb_log_file_size = 5M
#innodb_log_buffer_size = 8M
#innodb_flush_log_at_trx_commit = 1

  保存，然后重启mysql服务.重新登陆mysql，并查看编码：

 

mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+--------------------------+
| Variable_name            | Value                    |

| character_set_connection | utf8                     |

8 rows in set (0.00 sec)

mysql> SHOW VARIABLES LIKE 'collation%';
+----------------------+-----------------+

+----------------------+-----------------+
| collation_connection | utf8_general_ci |

| collation_server     | utf8_bin        |
+----------------------+-----------------+
3 rows in set (0.00 sec)

 

  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。
