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
windows noinstall安装配置mysql5.51.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: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 4 Server version: 5.5.34-log MySQL Community Server (GPL) Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql>
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 Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 9 Server version: 5.5.34-log MySQL Community Server (GPL) Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql>? 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 net_buffer_length = 8K 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! # #skip-networking # 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=, 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='125.564.12.1', 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 = # # 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 = # # 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 % # of RAM but beware of setting memory usage too high #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 #innodb_lock_wait_timeout = 50 [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash default-character-set=utf8 # Remove the next comment character if you are not familiar with SQL #safe-updates [myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout
??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_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | 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 | utf8_general_ci | | collation_database | utf8_bin | | 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。
