MySQL跨主機複製表

轉載 https://blog.csdn.net/yabingshi_tech/article/details/44645719

方法一： SQLyog 複製

方法二 

一：實驗環境

--這裏把主機名爲target_pc的機器當做源端，把主機名爲source_pc的機器當做目標端。 

不要被主機名混淆了。

二：實驗步驟

這裏介紹遷移所有數據庫和遷移單個數據庫時的數據遷移步驟。

2.1：遷移所有數據庫

2.1.1 遷移前環境

遷移前，源端有以下數據庫：

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| dan                |
| mysql              |
| performance_schema |
| test               |
+--------------------+
5 rows in set (0.00 sec)

遷移前，目標端的有以下數據庫：

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
+--------------------+
4 rows in set (0.01 sec)

 

源端比目標端多一個dan數據庫。

--目標端是剛安裝好的mysql，默認就有這4個數據庫。

2.1.2 在源端備份所有數據庫 

[root@target_pc databasefile]# mysqldump -u root -p --all-databases > /backup/databasefile/all_databases_20150325.bak

2.2.2 拷貝備份文件到目標端

[root@target_pc databasefile]# scp all_databases_20150325.bak 192.168.8.225:/backup/databasefile/
The authenticity of host '192.168.8.225 (192.168.8.225)' can't be established.
RSA key fingerprint is ed:ee:f6:e6:f5:3b:76:ed:18:fa:2d:eb:73:83:0e:13.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.8.225' (RSA) to the list of known hosts.

[root@target_pc databasefile]#

2.2.3 在目標端還原所有數據庫 

[root@source_pc databasefile]# mysql -u root -p < all_databases_20150325.bak 

Enter password: 

2.2.4 驗證

[root@source_pc databasefile]# mysql -u root -p
Enter password:

--注意：當遷移所有數據庫時，不用提前在目標端創建好所有數據庫。

 

2.2：遷移某個數據庫

2.2.1 準備測試數據

在源端新建一個數據庫：

mysql> create database jiao;
Query OK, 1 row affected (0.01 sec)

mysql> use jiao;
Database changed
mysql> create table t(id int);
Query OK, 0 rows affected (0.05 sec)

mysql> insert into t(id) values(1);
Query OK, 1 row affected (0.00 sec)

mysql> insert into t(id) values(2);
Query OK, 1 row affected (0.00 sec)

mysql> commit;
Query OK, 0 rows affected (0.00 sec)

mysql> select * from t;
+------+
| id   |
+------+
|    1 |
|    2 |
+------+
2 rows in set (0.00 sec)

 

2.2.2 在源端備份新增的這個數據庫

[root@target_pc databasefile]# mysqldump -u root -p jiao > /backup/databasefile/jiao_20150325.bak

Enter password: 

2.2.3 拷貝備份文件到目標端

[root@target_pc databasefile]# scp jiao_20150325.bak 192.168.8.225:/backup/databasefile/
[email protected]'s password:
jiao_20150325.bak                                                                                                                                             100% 1757     1.7KB/s   00:00
[root@target_pc databasefile]#

2.2.4 在目標端創建好該數據庫

mysql> create database jiao;

Query OK, 1 row affected (0.00 sec)

 

2.2.5 在目標端還原該數據庫

[root@source_pc databasefile]# mysql -u root -p < jiao_20150325.bak

Enter password: 

 

2.2.6 驗證

 

[root@source_pc databasefile]# mysql -u root -p
