MariaDB 10.3.28 CentOS 8 服务器上的性能缓慢

Question

I have a server running CentOS 8 with apache, php-fpm, and mariadb. The last one is giving problems to me.

I tried to import a database of a site into phpmyadmin with the apposite interface and also with mysql command.

The test with interface has been as slow as the timeout of apache (600s) giving to me gateway timeout. The test with mysql command has taken over 6 minutes!

The dump was something like 2MB so it is really unacceptable.

Do you know something I could change in configuration in order to solve this situation?

Already tried this in /etc/my.cnf but nothing happened:

[mysqld]
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /var/log/mariadb/slow-query.log

query_cache_type = 1
query_cache_limit = 8M
query_cache_size = 512M

max_connections = 500

tmp_table_size= 768M
max_heap_table_size= 768M

thread_cache_size = 12


join_buffer_size = 12M

The hardware of the machine I think it shouldn't be a problem, anyway:

• 4 cpu
• 5028 MB ram

Answer 1

yes, the individual configurations are in subdirectories. take a look at the subdirs of / etc / mysql eg ./mariadb.conf.d
