Mysql备份III

Mysqldump和mysqldumper

A备份和恢复所有库

$ time mysqldumo –all-databases > /mysql/backup/date.time.database.dump.sql
$ echo $?
$ ls -lah /mysql/backup/date.time.database.dump.sql
$ time mysql -u[user] -p -f < date.time.database.dump.sql > 
date.time.database.dump.sql.out 2>&1
$echo $?
$ls -lah date.time.database.dump.sql.out

$/usr/local/mysql/bin/mysqldump -S /tmp/mysql.sock -u root -p password -A
>/mysql/backup/ date.time.database.dump.sql
$mysql -S /tmp/mysql.sock -p password < /mysql/backup/ date.time.database.dump.sql

B备份和恢复一个库

$/usr/local/mysql/bin/mysqldump -S /tmp/mysql.sock -u root -p password databasename
(这里是库名)
>/mysql/backup/ date.time.databasename.dump.sql
$Mysql -S /tmp/mysql.sock -u root -p password databasename < /mysql/backup/ date.time.databasename.dump.sql

Or

Mysql>create database databasename;
Mysql>use databasename;
Mysql>system pwd
/mysql/backup
Mysql>source /mysql/backup/ date.time.databasename.dump.sql
Mysql>show tables;

C备份和恢复一个表

$/usr/local/mysql/bin/mysqldump -S /tmp/mysql.sock -u root -p password databasename
(这里是库名) tablename(表名)
>/mysql/backup/ date.time.databasename.tablename.port.dump.sql

$Mysql -S /tmp/mysql.sock -u root -p password databasename < /mysql/backup/ date.time.databasename.tablename.port.dump.sql

#
#cm -e “unlock tables;”

D备份和恢复表结构

$ mysqldump–all-databases –no-data 
> /mysql/backup/date.time.database.dumpschema.sql
$ echo $?
$ ls -lah /mysql/backup/date.time.database.dumpschema.sql
$ time mysql -u[user] -p -f < date.time.database.dumpschema.sql > 
date.time.database.dumpschema.sql.out 2>&1
$echo $?
$ls -lah date.time.database.dumpschema.sql.out

E备份和恢复存储过程和触发器

$ mysqldump–all-databases –no-data –no-create-info –events –routines 
> /mysql/backup/date.time.database.dumpobjects.sql
$ echo $?
$ ls -lah /mysql/backup/date.time.database.dumpobjects.sql
$ time mysql -u[user] -p -f < date.time.database.dumpobjects.sql > 
date.time.database.dumpobjects.sql.out 2>&1
$echo $?
$ls -lah date.time.database.dumpobjects.sql.out


$/usr/local/mysql/bin/mysqldump -S /tmp/mysql.sock -u root -p password -R –triggers -d -E -A > /mysql/backup/time.date.datebasename.triggereventsfunctions.dump.sql
$/usr/local/mysql/bin/mysql -S /tmp/mysql.sock -u root -p password <
/mysql/backup/time.date.datebasename.triggereventsfunctions.dump.sql

数据恢复过程中闪退需要检查字符集和环境需要手工修改文件修复
