#1016-无法打开文件:'./database_name/#sql-38f_36aa.frm'(errno:24) [英] #1016 - Can't open file: './database_name/#sql-38f_36aa.frm' (errno: 24)
问题描述
我在具有MyISAM存储引擎的mysql中有表. 我想在特定表上创建分区，为此，我正在执行查询-
I have table in mysql with MyISAM storage engine. I want to create partition on a particular table, for this I am executing the query -
alter table Stops PARTITION BY KEY(`stop_id`) PARTITIONS 200
其中"stop_id"是varchar的类型.执行上述查询时，出现错误-
Where 'stop_id' is type of varchar. While executing the above query I am getting the error -
#1016 - Can't open file: './database_name/#sql-38f_36aa.frm' (errno: 24)
有人可以帮我解决这个问题吗?
Can anybody please help me to resolve this problem?
谢谢.
推荐答案
errno:24表示给定进程打开了太多文件. 有一个名为"open_files_limit"的只读mysql变量，该变量 将显示mysqld允许多少个打开文件:
errno: 24 means that too many files are open for the given process. There is a read-only mysql variable called 'open_files_limit' that will show how many open files are allowed by the mysqld:
SHOW VARIABLES LIKE 'open%';
许多系统将此值设置为非常低的值，例如1024. 不幸的是，以下操作无效:
A lot systems set this to something very low, like 1024. Unfortunately, the following will NOT work:
SET open_files_limit = 100000
SET open_files_limit=100000
MySQL将回应:
错误1238(HY000):变量'open_files_limit'是只读的 变量
ERROR 1238 (HY000): Variable 'open_files_limit' is a read only variable
但是，可以对/etc/my.cnf进行更改.该文件可能 不存在，如果不存在，就创建它.确保它具有以下内容 内容:
However, it is possible to make a change to /etc/my.cnf. This file may not exist, if not, just create it. Be sure it has the following contents:
[mysqld]
open-files-limit = 100000
然后，请确保重新启动mysql:
Then, be sure to restart mysql:
sudo/etc/init.d/mysql重新启动
sudo /etc/init.d/mysql restart
现在，像"open％"这样的SHOW VARIABLES应该显示100000. 用途可能有所不同.
Now, SHOW VARIABLES LIKE 'open%' should show 100000. The number you use may be different.
