Linux和Windows环境下初始化mysql Linux环境中,安装好mysql后,还不能直接启动服务,必须先对数据库进行初始化。初始化的工作主要包括:  初始化日志、表空间等数据库必须的文件;创建并初始化系统数据库(mysql)。
 初始化完成后,启动mysqld守护进程,方可访问数据库。在Windows的环境下,安装包内已经自带了一个初始化好的环境,安装后展开在mysql根目录的data子目录。
所以并不需要手工进行初始化。但是某些情况下,也可能需要从零开始初始化数据库,比如:   数据文件被破坏,需要重建;希望保留现有环境不动,建立一个新的环境;希望建立一个干净的环境。
 不幸的是,Linux环境下是利用mysql_install_db.sh脚本初始化数据库环境的;而在windows版中并没有提供相应的脚本。那么该怎么办呢?经过对Linux环境下的mysql_install_db.sh的分析,发现初始化数据库的命令主要是以下几行: mysql_install_db.sh# Pipe mysql_system_tables.sql to "mysqld --bootstrap"s_echo "Installing MySQL system tables..."if { echo "use mysql;"; cat $create_system_tables $fill_system_tables; } | eval "$filter_cmd_line" | $mysqld_install_cmd_line > /dev/nullthens_echo "OK"s_echo "Filling help tables..."# Pipe fill_help_tables.sql to "mysqld --bootstrap"if { echo "use mysql;"; cat $fill_help_tables; } | $mysqld_install_cmd_line > /dev/nullthens_echo "OK" 其中:$create_system_tables、$fill_system_tables和$fill_help_tables分别是创建系统数据库、初始化系统数据库中的数据、和初始化帮助数据;    
 $filter_cmd_line是过滤掉主机名(用于交叉初始化非本机运行数据库环境的情况,可忽略);$mysqld_install_cmd_line主要是"mysqld --bootstrap"命令; 分析清楚上述内容,就可以自己手工初始化数据库了。具体步骤如下:设置mysql配置文件。主要是设置basedir(mysql的home目录,如:/opt/mysql-5.1.40)和datadir
(数据库文件目录,如:/var/db/mysql)两个参数。 初始化数据库目录,检查/var/db/mysql和/var/db/mysql/mysql(系统数据库)目录是否存在,若不存在则手工创建之。准备初始化数据库的sql脚本。将/opt/mysql-5.1.40/share目录下的mysql_system_tables.sql、 mysql_system_tables_data.sql和fill_help_tables.sql三个文件拷贝到/tmp目录下,并在每个文件的最开始插入“use mysql;”一行。   执行下列命令,初始化数据库:/opt/mysql-5.1.40/bin/mysqld.exe --bootstrap --console
