mysqldump

概述： 文档中使用smtp协议，利用QQ邮箱发送邮件，其中客户端授权码是在开启QQ邮箱smtp服务是官方给予的，所以要牢记！！！ 1、配置smtp #Linux yum install -y mailx #修改配置文件 vi /etc/mail.rc #在末尾追加如下内容并保存 set from=xxxxxxx@qq.com #设置发件人 set smtp=smtp.qq.com #设置外部STMP服务器 set smtp-auth-user=xxxxxxx@qq.com #设置STMP用户名 set smtp-auth-password=xxxxxxx #客户端授权码 set smtp-auth=login #测试 echo "this is my test mail" | mail -s 'mail test' xxxxxxx@qq.com 2、建立备份目录 mkdir -p /home/mysql/data/backup/mysql chown mysql:mysql /home/mysql/data/backup/mysql 3、备份脚本 cd /home/mysql/data/backup/mysql chmod +x mysqldump.sh vi mysqldump.sh #!/bin/bash BACKUP_PATH=/home/mysql/data/backup

I have a set of tables in my database that I have to take a dump ( :D ) of. My problem is I want to take some data from some tables that only date back certain days and would like to keep the remaining tables in tact. The query I came up with was something like: mysqldump -h<hostname> -u<username> -p <databasename> <table1> <table2> <table3> <table4> --where 'created > DATE_SUB(now(), INTERVAL 7 DAY)', <table5> --where 'created > DATE_SUB(now(), INTERVAL 7 DAY) --single-transaction --no-create-info | gzip > $(date +%Y-%m-%d-%H)-dump.sql.gz The trouble with the above code is that table1, table2

一、导出数据库用mysqldump命令（注意mysql的安装路径，即此命令的路径）： 1、导出数据和表结构： mysqldump -u用户名 -p密码 数据库名 > 数据库名.sql #/usr/local/mysql/bin/ mysqldump -uroot -p abc > abc.sql 敲回车后会提示输入密码 2、只导出表结构 mysqldump -u用户名 -p密码 -d 数据库名 > 数据库名.sql #/usr/local/mysql/bin/ mysqldump -uroot -p -d abc > abc.sql 注：/usr/local/mysql/bin/ ---> mysql的data目录 二、导入数据库 1、首先建空数据库 mysql>create database abc; 2、导入数据库 方法一： （1）选择数据库 mysql>use abc; （2）设置数据库编码 mysql>set names utf8; （3）导入数据（注意sql文件的路径） mysql>source /home/abc/abc.sql; 方法二： mysql -u用户名 -p密码 数据库名 < 数据库名.sql #mysql -uabc_f -p abc < abc.sql 来源： https://www.cnblogs.com/sung1024/p/11437223

i am trying to import a sql dump of magento along with some product data and i get this foreign key constraint error: `ERROR 1452 (23000) at line 231680: Cannot add or update a child row: a foreign key constraint fails: `magento`.`#sql-b33_27`, CONSTRAINT `FK_CATALOG_COMPARE_ITEM_CUSTOMER_ID_CUSTOMER_ENTITY_ENTITY_ID` FOREIGN KEY (`customer_id`) REFERENCES `customer_entity` (`entity_id`) ON DELETE CASCADE ON )` This is the sql code which is causing the error : -- -- Constraints for table `catalog_eav_attribute` -- ALTER TABLE `catalog_eav_attribute` ADD CONSTRAINT `FK_CATALOG_EAV_ATTRIBUTE

I am trying to import a mysqldump file via the command line, but continue to get an error. I dumped the file from my other server using: mysqldump -u XXX -p database_name > database.sql Then I try to import the file with: mysql -u XXX -p database_name < database.sql It loads a small portion and then gets stuck. The error I receive is: ERROR at line 1153: Unknown command '\''. I checked that line in the file with: awk '{ if (NR==1153) print $0 }' database.sql >> line1153.sql and it happens to be over 1MB in size, just for that line. Any ideas what might be going on here? You have binary blobs

How can i use mysqldump to backup and restore database to a remote server? Both have root access. I am using putty to perform this. So far I tried the following: mysqldump -u root -p >z*x311a!@ masdagn_joom15 | mysql \ -u root -p g2154hE6-AsXP --host=207.210.71.26 -C masdagn_joom15temp \g but it refused the local password is: >z*x311a!@ the remote password is: g2154hE6-AsXP NebuSoft This link provides information on backing up and restoring with mysqldump. It also gives some examples with a remote server. The important commands from that link being: backup: mysqldump -u root -p[root_password]
