mysql免安装版如何使用？_随笔

解压MySQL（F:\Program Files\MySQL\）MySQL安装目录二新建my.ini \x0d\x0a在F:\Program Files\MySQL\下建立my.ini文件，内容为 my.ini \x0d\x0a[mysqld] \x0d\x0a# 设置mysql的安装目录 \x0d\x0abasedir=F:\\Program Files\\MySQL \x0d\x0a# 设置mysql数据库的数据的存放目录，必须是data，或者是\\xxx-data datadir=F:\\Program Files\\MySQL\\data # 设置mysql服务器的字符集，默认编码 default-character-set=latin1 \x0d\x0a \x0d\x0a[client] \x0d\x0a# 设置mysql客户端的字符集 default-character-set=latin1 \x0d\x0a \x0d\x0a[WinMySQLAdmin] \x0d\x0a\x0d\x0a# 指定mysql服务启动启动的文件 \x0d\x0aServer=F:\\Program Files\\MySQL\\bin\\mysqld.exe \x0d\x0a \x0d\x0a三注册MySQL服务，使MySQL可以在服务项目中启动或关闭 \x0d\x0a 1）进入安装目录\bin，执行： \x0d\x0aF:\Program Files\MySQL\bin>mysqld -install \x0d\x0a显示：Service successfully installed. 则注册服务成功。 \x0d\x0a如果要删除服务： \x0d\x0aF:\Program Files\MySQL\bin>mysqld -remove 2）修改注册表： \x0d\x0aHKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MySQL\ImagePath 修改为： \x0d\x0a"F:\Program Files\MySQL\bin\mysqld" --defaults-file= "F:\Program Files\MySQL\my.ini" MySQL \x0d\x0a这样配置就可以使用net start mysql命令正常启动MySQL。 \x0d\x0a四修改root密码 \x0d\x0aMySQL配置好后，启动成功，默认密码是空，但是为了安全，设置密码（一般用户名为root，密码为root）。 \x0d\x0a1）登录MySQL root用户： \x0d\x0a 进入MySQL安装目录\bin，执行： \x0d\x0a F:\Program Files\MySQL\MySQL-6.0.7\bin>mysql -u root2）修改root密码： \x0d\x0a mysql>update mysql.user set password=PASSWORD(''新密码'') where User=''root'' \x0d\x0a mysql>flush privileges

Liunx下修改MySQL字符集：

1.查找MySQL的cnf文件的位置

find / -iname '*.cnf' -print

/usr/share/mysql/my-innodb-heavy-4G.cnf

/usr/share/mysql/my-large.cnf

/usr/share/mysql/my-small.cnf

/usr/share/mysql/my-medium.cnf

/usr/share/mysql/my-huge.cnf

/usr/share/texmf/web2c/texmf.cnf

/usr/share/texmf/web2c/mktex.cnf

/usr/share/texmf/web2c/fmtutil.cnf

/usr/share/texmf/tex/xmltex/xmltexfmtutil.cnf

/usr/share/texmf/tex/jadetex/jadefmtutil.cnf

/usr/share/doc/MySQL-server-community-5.1.22/my-innodb-heavy-4G.cnf

/usr/share/doc/MySQL-server-community-5.1.22/my-large.cnf

/usr/share/doc/MySQL-server-community-5.1.22/my-small.cnf

/usr/share/doc/MySQL-server-community-5.1.22/my-medium.cnf

/usr/share/doc/MySQL-server-community-5.1.22/my-huge.cnf

2. 拷贝 small.cnf、my-medium.cnf、my-huge.cnf、my-innodb-heavy-4G.cnf其中的一个到/etc下，命名为my.cnf

cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

3. 修改my.cnf

vi /etc/my.cnf

在[client]下添加

default-character-set=utf8

在[mysqld]下添加

default-character-set=utf8

4.重新启动MySQL

[root@bogon ~]# /etc/rc.d/init.d/mysql restart

Shutting down MySQL [ 确定 ]

Starting MySQL. [ 确定 ]

[root@bogon ~]# mysql -u root -p

Enter password:

Welcome to the MySQL monitor. Commands end with or \g.

Your MySQL connection id is 1

Server version: 5.1.22-rc-community-log MySQL Community Edition (GPL)

Type 'help' or '\h' for help. Type '\c' to clear the buffer.

5.查看字符集设置

mysql>show variables like 'collation_%'

+----------------------+-----------------+

| Variable_name | Value|

+----------------------+-----------------+

| collation_connection | utf8_general_ci |

| collation_database| utf8_general_ci |

| collation_server | utf8_general_ci |

+----------------------+-----------------+

3 rows in set (0.02 sec)

mysql>show variables like 'character_set_%'

+--------------------------+----------------------------+

| 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| /usr/share/mysql/charsets/ |

+--------------------------+----------------------------+

8 rows in set (0.02 sec)

mysql>

其他的一些设置方法：

修改数据库的字符集

mysql>use mydb

mysql>alter database mydb character set utf-8

创建数据库指定数据库的字符集

mysql>create database mydb character set utf-8

通过配置文件修改:

修改/var/lib/mysql/mydb/db.opt

default-character-set=latin1

default-collation=latin1_swedish_ci

为

default-character-set=utf8

default-collation=utf8_general_ci

重起MySQL:

[root@bogon ~]# /etc/rc.d/init.d/mysql restart

通过MySQL命令行修改:

mysql>set character_set_client=utf8
