You did not specify --alter-foreign-keys-method, but there are foreign keys that reference the table. Please read the tool's documentation carefully.
发现报错，提示有个表：online_ddl_log有外键参照表online_ddl，需要使用--alter-foreign-keys-method参数指明对外键的操作。
--alter-foreign-keys-method 的值可以为：auto、rebuild_constraints、drop_swap、none 四种
1、当业务量较大时，修改操作会等待没有数据修改后，执行最后的rename操作。因此，在修改表结构时，应该尽量选择在业务相对空闲时，至少修改表上的数据操作较低时，执行较为妥当。
2、如果对外键表操作时，四种外键操作类型需要根据表的数据量和可靠程度，进行选择。处于可靠性的原因，尽量使用rebuild_constraints类型，如果没有可靠性要求，可以使用auto类型。
3、当--alter-foreign-keys-method=none时，外键索引将失效，需要重建外键索引，方可再次使用
4、由于可能存在一定的风险，在操作之前，建议对数据表进行备份，可以使得操作更安全、可靠。
加上--alter-foreign-keys-method 参数，再次执行：
root@ljd-python:~# pt-online-schema-change --user=root --password=123456 --host=192.168.0.3 --port=3306 --charset=utf8 --nodrop-old-table --alter="add column uuid varchar(60) null default null after id " D=test,t=online_ddl --exec --alter-foreign-keys-method=rebuild_constraints
