mysqldump

一、mysql常用导出数据命令 1.mysql导出整个数据库 mysqldump -hhostname -uusername -ppassword databasename > backupfile.sql　　 mysqldump -hlocalhost -uroot hqgr> hqgr.sql (如果root用户没用密码可以不写-p，当然导出的sql文件你可以制定一个路径，未指定则存放在mysql的bin目录下) 2.mysql导出数据库一个表 　　 mysqldump -hhostname -uusername -ppassword database tablename> 导出的文件名 mysqldump -hlocalhost -uroot hqgr t_ug_user> user.sql 3.mysql导出一个数据库结构 　　 mysqldump -hhostname -uusername -ppassword -d --add-drop-table databasename > d:hqgrstructure.sql -d 没有数据 --add-drop-table 在每个create语句之前增加一个drop table 4.如果需要导出mysql里面的函数或者存储过程 mysqldump -hhostname -uusername -ppassword -ntd -R

I'm writing a single line command that backups all databases into their respective names instead using of dumping all in one sql. Eg: db1 get saved to db1.sql and db2 gets saved to db2.sql So far, I'd gathered the following commands to retrieve all databases. mysql -uuname -ppwd -e 'show databases' | grep -v 'Database' I'm planning to pipe it with awk to do something like awk '{mysqldump -uuname -ppwd $1 > $1.sql}' But that doesn't work. I'm new to bash, so I could be wrong in my thinking. What should I do to make it export the db in their respective names? update: Ok, have to finally managed

1， 创建mysqld数据库的管理用户： 要把root用户设置为管理员，我们应该运行下面的命令； [root@linuxsir01 root]# mysqladmin -u root password 123456 一般情况下，mysqladmin所在目录已经加到$PATH中，如果该命令没有找到，查看软件包安装是否正确，确保Mysql-server和Mysql-client两个软件包都已经安装成功，然后可以rpm -qf Mysql-client查看该命令安装到那个目录中，将该目录加到$PATH变量中，或者-www.2cto.com-使用全路径。 需要注意的是，这里的root不是系统用户，而是数据库用户了。你也可以取别的用户名。 2， 登陆mysql数据库 以mysql数据库管理员root，密码为123456为例； [root@linuxsir01root]#/opt/mysql/bin/mysql -u root -p 如果找不到该命令，检查PATH变量，出现 Enter password：输入密码，回车。 然后出现： Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 9 Server version: 5.5.8 MySQL Community Server

Is there a way to restrict certain tables from the mysqldump command? For example, I'd use the following syntax to dump only table1 and table2: mysqldump -u username -p database table1 table2 > database.sql But is there a similar way to dump all the tables except table1 and table2? I haven't found anything in the mysqldump documentation, so is brute-force (specifying all the table names) the only way to go? Paul Sheldrake You can use the --ignore-table option. So you could do mysqldump -u USERNAME -pPASSWORD DATABASE --ignore-table=DATABASE.table1 > database.sql There is no whitespace after -p
