最佳实践Mysql配置开发中？ [英] Best practice Mysql configuration in development?

问题描述

我在开发过程中启用了以下功能：

I enable the following during development:

my.cnf：

[mysqld]
log_slow_queries    = /var/log/mysql/mysql-slow.log
sql_mode            = STRICT_ALL_TABLES

SQL_MODE

STRICT_ALL_TABLES

为所有存储引擎启用严格模式。无效的数据值被拒绝
。

Enable strict mode for all storage engines. Invalid data values are rejected.

例如，请考虑以下内容：

For example, consider the following:

CREATE TABLE `posts` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `title` varchar(200) NOT NULL,
    `date` datetime NOT NULL
);
INSERT INTO `posts` (`title`, `date`) VALUES ('Title text', NULL);

如果使用 STRICT_ALL_TABLES sql_mode ，当尝试将 NULL 值插入<$ c $时，mysql将不抛出错误c> NOT NULL 列，取而代之的是mysql将根据列的类型插入默认数据。例如对于日期时间 NOT NULL 列，当您插入 NULL 值时，mysql将日期时间值默认为 0000-00-00 00-00-00 。

If you use STRICT_ALL_TABLES sql_mode, mysql will not throw an error when trying to insert a NULL value into a NOT NULL column, instead mysql will insert default data depending on the type of column. e.g. for a datetime NOT NULL column when you insert a NULL value, mysql will default the datetime value to 0000-00-00 00-00-00.

从某种意义上讲，严格模式就像提高了error_reporting级别并显示PHP中的错误，这是开发过程中的最佳做法。

Strict mode, in a sense, is like turning up the error_reporting level and displaying errors in PHP, which is a best practice during development.

ini_set('error_reporting', -1);
ini_set('display_errors', true);

所以，我猜我在找什么，在此期间您推荐的配置是什么开发以及为什么？

推荐答案

我建议以下其他选项：

# creates a innodb file per table instead of having all the tables in a single tablespace file
innodb_file_per_table 

# increase the max allowed packet to a large size for file imports
max_allowed_packet = 32M

# the InnoDB pool size. use up to 80% available RAM for dedicated machines, and as much
# as you can spare for development machines also depending on the size of the databases
# you will be running so that as much of the database as possible fits into memory 
innodb_buffer_pool_size = 512M
