[CentOS] 8.x MariaDB 10.3 시작 에러

CentOS 8 버전에서 mariadb 를 설치하고 my.cnf 환경 설정을 한 다음에 db를 시작했더니 아래와 같은 에러가 나네요~

설치는 # yum install mariadb* 이렇게 했습니다.

원인은 log_slow_queries = On 옵션 때문이더군요~

[root@localhost ~]# systemctl status mariadb

/etc/my.cnf 에 잘못된 설정이 있다는 내용같습니다.

작성한 /etc/my.cnf.d/my.cnf 파일에서 옵션을 하나씩 막고 테스트 해봤습니다.

[mysqld]
server-id=1
log-bin=mysql-bin
expire_logs_days=7
init_connect='set names utf8'
character-set-server=utf8
max_connections=1000
#log_slow_queries = On
long_query_time = 5
join_buffer_size = 16MB
key_buffer_size = 8MB
read_rnd_buffer_size = 32MB
sort_buffer_size = 32MB
query_cache_limit = 256KB
query_cache_min_res_unit = 4096
query_cache_size = 16MB
thread_cache_size = 8
table_open_cache = 16384
max_heap_table_size = 256MB
tmp_table_size = 256MB

MariaDB 10.3 버전에서는 log_slow_queries 옵션을 사용할 수가 없나봅니다~
