MySQL经常使用命令和配置

忽略一些表导出数据库

mysqldump -h 10.66.125.xx -u xx -p xx -t test_db --ignore-table=test_db.manalog --ignore-table=test_db.user_play_history  > test_db_bak.sql; 

 

所有导出

mysqldump -u xxx -p xxx > test_db.sql

 

去除权限

sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/ ' backup.sql > new_backup.sql

 

 

建立用户

CREATE USER 'julian'@'localhost' IDENTIFIED BY '123456';

 

权限

grant all privileges on *.* to  'julian'@'%' identified by '123456';

flush privileges;

 

 

建立发生错误，须要修改my.cnf

insert into mysql.user(Host,User,Password)  values("localhost","julian",password("123456")); 

 

 

忽略表名大小写

lower_case_table_names=1

default-character-set=utf8
