mysql解压版安装步骤

1.下载mysql-noinstall-5.1.50-win32.zip，解压到E盘(E:\mysql-5.1.50-win32)。

2.复制my-huge.ini为my.ini。

3.修改my.ini,在[client]、[mysqld]、[mysql]后面加default-character-set = utf8，在[mysqld]下加，basedir、datadir。
[client]
default-character-set = utf8
[mysqld]
default-character-set = utf8
default-collation=utf8_bin
init_connect='SET NAMES utf8'
basedir=E:\mysql-5.1.50-win32\ // 此处两目录需指向安装目录
datadir=E:\mysql-5.1.50-win32\data\ // 此处两目录需指向安装目录
[mysql]
default-character-set=utf8

 

4.安装mysql服务。(移除mysql服务mysqld --remove)
命令行下进入E:\mysql-5.1.50-win32\bin，运行mysqld --install mysql --defaults-file="E:\mysql-5.1.50-win32\my.ini"。
E:\mysql-5.1.50-win32\bin>mysqld --install mysql --defaults-file="E:\mysql-5.1.50-win32\my.ini"
Service successfully installed.
注：要加参数安装，不然mysql administrator启动时将提示:
Either the server service or the configuration file could not be found.Startup variable and service section are there for disabled.
进入后提示：
This section is only avaliable when connected to localhost

 

5.启动mysql服务.(停止mysql服务net stop mysql)
E:\mysql-5.1.50-win32\bin>net start mysql
mysql 服务正在启动 .
mysql 服务已经启动成功。

 

6.进入mysql，并给MYSQL的root用户加密码。
E:\mysql-5.1.50-win32\bin>mysql -uroot -p
Enter password:

此时密码为空，提示输入密码，直接回车。

E:\mysql-5.1.50-win32\bin>mysql -uroot -p
Enter password:
