我正在使用RubyRep设置对MySQL数据库的部分复制。但这不适用于某些表。我做错了什么?
这是一台运行MySQL 5的Linux CentOS服务器。我尝试在本地复制两个MySQL数据库,以在两个不同数据库中复制两种相同类型的表,效果很好。所以我在服务器上尝试了同样的方法。在服务器中,当我尝试新创建的表时,它可以正常工作,但对于某些现有表,则无法工作。
出勤表属性是
| Field | Type | Null | Key | Default | Extra |
+-------------------+--------------+------+-----+---------+-------+
| ATTENDANCE_DATE | datetime | NO | | NULL | |
| STUDENT_ID | int(10) | NO | | NULL | |
| CLASS_ID | int(10) | NO | | NULL | |
| STAFF_ID | int(10) | NO | | NULL | |
| ATTENDANCE_STATUS | char(1) | YES | | NULL | |
| LATE_STATUS | char(1) | YES | | NULL | |
| LATE_TIME | varchar(7) | YES | | NULL | |
| DROP_TIME | time | YES | | NULL | |
| PICK_TIME | time | YES | | NULL | |
| REMARKS | varchar(200) | YES | | NULL | |
| SCHOOL_ID | int(11) | YES | | NULL | |
| CREATED_ON | datetime | NO | | NULL | |
| CREATED_BY | varchar(15) | NO | | NULL | |
| MODIFIED_ON | datetime | YES | | NULL | |
| MODIFIED_BY | varchar(15) | YES | | NULL | |
+-------------------+--------------+------+-----+---------+-------+
而RubyRep的配置文件是:
RR::Initializer::run do |config|
config.left = {
:adapter => 'mysql2',
:database => 'database-A',
:username => '*******',
:password => '*******',
:host => 'localhost'
}
config.right = {
:adapter => 'mysql2',
:database => 'database-B',
:username => '*******',
:password => '*******',
:host => 'localhost'
}
config.left[:logger] = "log/left_database.log"
config.right[:logger] = "log/right_database.log"
config.options[:auto_key_limit] = 2
config.include_tables 'attendance', :replication_conflict_handing => :
left_wins, :sync_conflict_handling => :left_wins
# config.include_tables /^e/ # regexp matching all tables starting with e
# config.include_tables /./ # regexp matching all tables in the database
end
我希望在数据库A的出勤表中添加数据时,应该将其复制到数据库B的出勤表中。
现在,在运行复制命令本身时,该命令将失败,并显示错误消息
