dokcer 容器與主機(jī)之間的文件傳遞
mysql容器 /home/linking/mysql--------centos主機(jī)create.sql
step1：宿主機(jī)上找到container的id
docker ps|grep mysql--------------------example 5464
step4:執(zhí)行docker 命令
docker cp create.sql 5464:/home/linking/mysql ---把sql考入docker容器
step5:考出容器
docker cp c5464:/home/linking/mysql  create.sql---把sql考入docker容器



mysql表大小查看
step1:創(chuàng)建數(shù)據(jù)庫
create linking engine=innodb as select * from salary;
step2;查看表大小
show databases;
use information_scheme;
slece sum(data_length)+sum(index_length) from tables where table_schema='linking';
step3；改變表引擎，
show databases;
use yiibaidb;
alter table linking engine='myisam';
step4:step2
可以看見表engine 的變化會(huì)導(dǎo)致內(nèi)存不一樣。

mysql數(shù)據(jù)庫遠(yuǎn)程連接：
server-client
client上;mysql -h ip -uusername -p
enterpasswd:
show databases;
use tables;
use mysql;
select host,username,password fromuser；#可以看到server上放行的ip.username,password
