MYSQL迁移

数据库本地复制

这里复制数据库是为了在迁移前删除不要的数据。

导出源数据库：
使用mysqldump命令将源数据库导出到一个SQL文件中。

假设源数据库名为xhkjedu_school，目标数据库名为xhkjedu_school_20241107，你可以使用以下命令：

1
mysqldump -u root -p xhkjedu_school > xhkjedu_school.sql

这里的username是你的MySQL用户名。执行命令后，你会被提示输入密码。

创建目标数据库（如果目标数据库不存在）：
使用mysql命令创建目标数据库。

如果目标数据库已经存在，可以跳过这一步。

1
mysql -u root -p -e "CREATE DATABASE xhkjedu_school_20241107;"

导入数据到目标数据库：
使用mysql命令将导出的SQL文件导入到目标数据库中。

1
mysql -u root -p xhkjedu_school_20241107 < xhkjedu_school.sql

处理数据

  concat( 'delete from ', TABLE_SCHEMA, '.', TABLE_name, ';' ) 
FROM

  AND TABLE_NAME LIKE 'e_%';

SELECT 
    TABLE_SCHEMA AS '数据库名',

    ROUND(DATA_LENGTH / 1024 / 1024, 2) AS '数据大小(MB)',
    ROUND(INDEX_LENGTH / 1024 / 1024, 2) AS '索引大小(MB)',
    ROUND((DATA_LENGTH + INDEX_LENGTH) / 1024 / 1024, 2) AS '总大小(MB)'
FROM 
    information_schema.TABLES
WHERE 
    TABLE_SCHEMA = 'xhkjedu_school_20241107'
ORDER BY 
    (DATA_LENGTH + INDEX_LENGTH) DESC;

处理数据后导出

1
mysqldump -u root -p xhkjedu_school_20241107 > xhkjedu_school_20241107.sql

导入PolarDB

mysql -h127.0.0.1 -P4886 -u root -e "CREATE DATABASE xhkjedu_school;"

mysql -h127.0.0.1 -P4886 -u root xhkjedu_school < xhkjedu_school_20241107.sql

压缩与解压

压缩

1
tar -czvf xhkjedu_school.sql.tar.gz xhkjedu_school.sql

压缩基本可以节约一半多点的空间

解压

1
tar -xzvf xhkjedu_school.sql.tar.gz

服务器间复制

从本地复制到远程

复制单个文件

1
scp /data/db/testdb.sql root@111.111.111.111:/data/db/testdb.sql

复制目录

1
scp -r /data/db/* root@111.111.111.111:/data/db/

查看数据行数

生成查询各表条数的SQL

select concat(
    'select "',

    TABLE_SCHEMA,
    '.',
    TABLE_name,
    ' union '
) from information_schema.tables
where TABLE_SCHEMA='xhkjedu_school_20241107';

把查询出来的结果整体复制后 删除最后一个union 整体全选运行即可

ln -s /data/db/Kingbase/KESRealPro/V009R003C011/Server/bin/sys_restore /usr/bin/sys_restore

SQL导出导入

导出SQL

1
sys_dump -U root -d xhkjedu_school_zm -F p -f /root/xhkjedu_school_zm.sql

导入 SQL

连接

1
ksql -U system test

创建数据库

1
CREATE DATABASE xhkjedu_school_zm ENCODING 'UTF8' TEMPLATE template0;

退出 ksql
创建数据库完成后，使用 \l 命令查看数据库列表，可使用 \q 命令退出 ksql 交互界面。

导入

如果之前使用 sys_dump 导出的是 SQL 脚本，可以使用 psql 工具将其导入到目标数据库中。

1
ksql -U system -d xhkjedu_school_zm -f /root/xhkjedu_school_zm.sql

其中

  • -U username：指定数据库的用户名。
  • -d dbname：指定要导入数据的数据库名称。
  • -f /path/to/output.sql：指定要导入的 SQL 脚本文件的路径。

修改配置

1
find . -type f -name "application.properties" -exec sed -i 's/xhkjedu_school?currentSchema=xhkjedu_school/xhkjedu_school_zm?currentSchema=xhkjedu_school_zm/g' {} \;

压缩与解压

压缩

1
tar -czvf xhkjedu_school.sql.tar.gz xhkjedu_school.sql

压缩基本可以节约一半多点的空间

解压

1
tar -xzvf xhkjedu_school.sql.tar.gz
