내 open_files_limitmysql 만 있기 때문에 문제 가 발생합니다 1024.

Centos 7, MySQL 커뮤니티 서버 5.6.22-log

실제로 WHM 서버 (원격 mysql)를 위해 mysql 전용의 vps이지만, 그 지점 옆에 있어야합니다.

구성 파일

my.cnf:

[mysqld]
open_files_limit = 100000
open-files-limit = 100000 #I've read that the dashes are required on older versions, but I threw it in anyway.
innodb_buffer_pool_size = 600M
...

# and the same for mysqld_safe
[mysqld_safe]
open_files_limit = 100000
open-files-limit = 100000
...

/etc/security/limits.conf:

*       hard    nofile  100000
*       soft    nofile  100000

명령 출력

루트에 대한 내 os open_files_limit :

[root@mack ~]# ulimit -Hn -Sn
open files                      (-n) 100000
open files                      (-n) 100000

그리고 mysql 사용자로서 :

[root@mack ~]# su mysql
bash-4.2$ ulimit -Hn -Sn
open files                      (-n) 100000
open files                      (-n) 100000

MySQL 상태 :

[root@mack ~]# service mysql status

mysql을 다시 시작하고 중지하고 상태를 확인하여 중지되었는지 확인한 다음 시작한 다음 전체 시스템을 재부팅했습니다.

my.cnf작동하는 증거 :

mysql> show global variables like '%buffer_pool_size%';
+-------------------------+-----------+
| Variable_name           | Value     |
+-------------------------+-----------+
| innodb_buffer_pool_size | 629145600 |
+-------------------------+-----------+
1 row in set (0.00 sec)

이제 내 혈압이 올라갑니다.

mysql> show global variables like 'open%';
+------------------+-------+
| Variable_name    | Value |
+------------------+-------+
| open_files_limit | 1024  |
+------------------+-------+
1 row in set (0.00 sec)

내가 무엇을 놓치고 있습니까? 내 가치를 덮어 쓰는 또 다른 my.cnf가 있습니까?

[root@mack ~]# find / -name "*.cnf"
/usr/share/mysql/my-default.cnf
/usr/share/doc/mysql-community-server-5.6.22/my-default.cnf
/var/lib/mysql/auto.cnf
/etc/my.cnf
/etc/pki/tls/openssl.cnf

나는 그 모든 것을 조사했으며 open_files_limit에 대한 언급이 없습니다. 그것을 위해, 나는 grep설정을 찾는 이들을 겪었습니다.

[root@mack ~]# grep -r "open_files_limit" /etc
/etc/my.cnf:open_files_limit = 100000
/etc/my.cnf:open_files_limit = 100000
[root@mack ~]# grep -r "open_files_limit" /var
[root@mack ~]# grep -r "open_files_limit" /usr
/usr/share/vim/vim74/syntax/ora.vim:syn keyword oraKeywordUnd     _number_cached_attributes _offline_rollback_segments _open_files_limit

Binary file /usr/sbin/mysqld-debug matches
Binary file /usr/bin/mysqlbinlog matches
/usr/bin/mysqld_safe:      --open_files_limit=*) open_files="$val" ;;

그러나 그들은 영향을 미치지 않습니다.
