windows/linux服务器下mysql备份恢复命令介绍 在windows服务器下mysql备份恢复我们经常会使用mysqldump命令来完成这些操作,下面我来详细的总结一下mysqldump备份恢复命令的用法介绍。 设mysql安装在c:盘,mysql数据库的用户名是root,密码是123456,数据库名是database_name,在d:盘根目录下面存放备份数据库,备份数据库名字为backup20070713.sql(20070713.sql为备份日期)备份数据库:mysqldump 是采用SQL级别的备份机制,它将数据表导成 SQL 脚本文件,在不同的 MySQL 版本之间升级时相对比较合适,这也是最常用的备份方法。 代码如下    mysqldump -uroot -p123456 database_name>d:/backup20070713.sql上面windows/下面为linux我通常使用以下 SQL 来备份 MyISAM 表: 代码如下 /usr/local/mysql/bin/mysqldump -uyejr -pyejr --default-character-set=utf8 --opt --extended-insert=false --triggers -R --hex-blob -x db_name > db_name.sql 使用以下 SQL 来备份 Innodb 表: 代码如下 /usr/local/mysql/bin/mysqldump -uyejr -pyejr --default-character-set=utf8 --opt --extended-insert=false --triggers -R --hex-blob --single-transaction db_name > db_name.sql另外,如果想要实现在线备份,还可以使用 --master-data 参数来实现,如下: 代码如下 /usr/local/mysql/bin/mysqldump -uyejr -pyejr --default-character-set=utf8 --opt --master-data=1 --single-transaction --flush-logs db_name > db_name.sql 恢复数据库:删除原有数据库,建立数据库,把备份数据库导入。 代码如下 mysqladmin -uroot -p123456 drop database_namemysqladmin -uroot -p123456 create database_namemysql -uroot -p123456 database_name 用 mysqldump 备份出来的文件是一个可以直接倒入的 SQL 脚本,有两种方法可以将数据导入。直接用 mysql 客户端    例如: 代码如下 /usr/local/mysql/bin/mysql -uyejr -pyejr db_name /home/wuxiaoxiao/user.txt输出内容选项:--add-drop-database:每个数据库创建语句之前加上drop database语句--add-drop-table:每个表创建语句之前加上drop table语句-n:不包含数据库的创建语句-t:不包含数据表的创建语句-d:不包含数据输出格式选项:     --compact:使输出结果简洁 -c --compact-insert:使输出文件中的insert语句包含字段名 -T:将数据库表中的数据备份为单纯的数据文本和建表sql俩个文件   --fields-terminated-by=name(域分割符)   --fields-enclosed-by=name(域引用符)   --fields-optionally-enclosed-by=name(域可选引用符)   --fields-escaped-by=name(转移字符)eg:/usr/bin/mysqldump -u root -h 202.194.132.237 -P 3306 -p BBS user -T ./bak字符集选项:--default-character-set=name:设置导出的客户端字符集eg:mysql -u root -p --compact --default-character-set=utf8 BBS user > test.txt  来自壹聚教程网 bitsCN.com
