[Warning] Could not increase number of max_open_files to more than 1024(request:5035)

报错现象

[Warning] Could not increase number of max_open_files to more than 1024 (request: 5035)
[Warning] Changed limits: max_open_files: 1024 max_connections: 594 (was 4096) table_cache: 200 (was 2000)

注：出现警告信息：提示最大打开文件数不能超过1024，但依然能够启动mariaDB。

解决方法

vim /etc/systemd/system/mariadb.service

 14 # For example, if you want to increase mysql's open-files-limit to 10000,
 15 # you need to increase systemd's LimitNOFILE setting, so create a file named
 16 # "/etc/systemd/system/mariadb.service.d/limits.conf" containing:
 17 #       [Service]
 18 #       LimitNOFILE=10000  
 '//根据前面的warning信息，数值只需要大于上面提示的5035即可，还可以改为infinity '

验证

注：修改完之后，重新加载配置

systemctl daemon-reload
systemctl   restart  mariadb
systemctl   status   mariadb
