为了重新安装我的MySQL数据库,我删除了/etc/my.cnfMySQL:如何查看使用哪个配置文件?
但是MySQL的默认设置是什么?我如何看到哪些配置文件正在使用?
我可以看到,mysql --help
给了我一个当前设置的列表。但我真正的问题在于我想修改local-infile
和max_allowed_packet
。
帮助文字还声明它从以下文件中读取:/etc/my.cnf /etc/mysql/my.cnf /opt/local/etc/mysql5/my.cnf ~/.my.cnf
。但它们都不存在:
> cat /etc/my.cnf /etc/mysql/my.cnf /opt/local/etc/mysql5/my.cnf ~/.my.cnf
cat: /etc/my.cnf: No such file or directory
cat: /etc/mysql/my.cnf: No such file or directory
cat: /opt/local/etc/mysql5/my.cnf: No such file or directory
cat: /Users/jesper/.my.cnf: No such file or directory
我可以创建仅包含这些设置的新配置文件吗? 最具体的:如何查看正在使用的配置文件?
这里是mysql --help
