0. 需求
将已有的 Apollo 1.0 表数据导入 Apollo 2.0 表。目标库已经创建了 Apollo 2.0 的库表结构。2.0 版本比 1.0 版本多四个表：
ApolloConfigDB.AccessKey
ApolloConfigDB.ServiceRegistry
ApolloPortalDB.SPRING_SESSION
ApolloPortalDB.SPRING_SESSION_ATTRIBUTES
1. 导出 1.0 版本数据
只导出不带已经逻辑删除的数据。新版本部分表增加了删除时间戳字段，并在该字段上设置了联合其它字段的唯一索引。只导出 IsDeleted=0 的数据，防止插入新版本库时报违反唯一索引约束的错误。
# 导出 apolloconfigdb 库中所有包含 IsDeleted = 0 的表数据
mysqldump -uroot -p123456 -S /data/18251/mysqldata/mysql.sock --set-gtid-purged=off --no-create-db --no-create-info --skip-opt --complete-insert --quick --extended-insert apolloconfigdb app appnamespace audit cluster commit grayreleaserule item namespace namespacelock release releasehistory serverconfig --where="IsDeleted=0" > apolloconfigdb_IsDeleted_0.sql
# 导出 apolloconfigdb 库中不包含 IsDeleted 字段的表数据
mysqldump -uroot -p123456 -S /data/18251/mysqldata/mysql.sock --set-gtid-purged=off --no-create-db --no-create-info --skip-opt --complete-insert --quick --extended-insert apolloconfigdb instance instanceconfig releasemessage > apolloconfigdb_no_IsDeleted.sql
# 导出 apolloportaldb 库中所有包含 IsDeleted = 0 的表数据

# 导出 apolloportaldb 库中不包含 IsDeleted 字段的表数据
mysqldump -uroot -p123456 -S /data/18251/mysqldata/mysql.sock --set-gtid-purged=off --no-create-db --no-create-info --skip-opt --complete-insert --quick --extended-insert apolloportaldb authorities consumeraudit users > apolloportaldb_no_IsDeleted.sql
2. 转换大小写
现实中 1.0 的库表名称可能都为小写，而 2.0 的库表名称可能区分大小写。
# 库名

sed -i 's/USE `apolloconfigdb`/USE `ApolloConfigDB`/g;' apolloconfigdb_no_IsDeleted.sql

3. 数据导入 2.0 版本库
mysql -uroot -p123456 -h127.0.0.1 -P3306 -D ApolloPortalDB < /var/lib/mysql/apolloportaldb_no_IsDeleted.sql > apolloportaldb_no_IsDeleted.log 2>&1
mysql -uroot -p123456 -h127.0.0.1 -P3306 -D ApolloConfigDB < /var/lib/mysql/apolloconfigdb_no_IsDeleted.sql > apolloconfigdb_no_IsDeleted.log 2>&1
mysql -uroot -p123456 -h127.0.0.1 -P3306 -D ApolloPortalDB < /var/lib/mysql/apolloportaldb_IsDeleted_0.sql > apolloportaldb_IsDeleted_0.log 2>&1
