Mysql插入中文数据乱码，网上说修改my.cof，可我的电脑里没有这个文件（/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf 都没有）
我先停用mysql,再新建my.cof文件输入类似：
character_set_server=utf8
init_connect='SET NAMES utf8'
或者stackoverflow上其它的都试了，再启动mysql还是显示：
mysql> show variables like '%character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | latin1 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
直接创建文件是不是不行？请问有默认模板吗？另外我是apt-get安装的mysql
崩溃中。。。请大神指点，感激不尽
环境：
ubuntu14.04
mysql5.5.41
找找/usr/share/mysql/my.cnf，没有的话用find命令查找一下：
sudo find / -name my.cnf
或者查看进程信息查看加载了哪个配置文件
cat /proc/$(pidof mysqld)/cmdline | tr '\0' '\n'
mysql可以在启动命令上加上 --defaults-file='path/to/my.cnf' 指定按照某个配置文件进行启动
14.04用sudo apt-get install mysql-server是存在文件/etc/mysql/my.cnf的.
/usr/bin/mysql --help|grep -B 1 /etc/mysql/my.cnf
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf
后面的优先级更高,建议只保留一个配置文件/etc/mysql/my.cnf.

apt-get download mysql-common 下载这个包,里面有个这个文件.
在配置里的[mysqld]下加入:
character_set_server=utf8
另外,注意创建数据库和表时也指定编码:
CREATE DATABASE IF NOT EXISTS mybase DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
USE mybase;
CREATE TABLE `posts` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`post_title` varchar(255) NOT NULL DEFAULT '',
`post_content` text,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=0 DEFAULT CHARSET=utf8;
连接数据库时也制定编码,比如PHP:
<?php
$dsn = "mysql:dbname=$app[db_name];host=$app[db_host];port=$app[db_port];charset=utf8";
$dbh = new PDO($dsn, $app['db_username'], $app['db_password'], array(
PDO::ATTR_PERSISTENT => $app['db_pconnect'],
PDO::ATTR_EMULATE_PREPARES => false,
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8'
));
页面输出也指定UTF-8编码:
<?php
header('Content-Type: text/html; charset=utf-8');
?>
<meta charset="utf-8">
编辑器和IDE里也使用UTF-8编码,统一下来后就不会乱码了.
这个设置对了么？
character_set_server=utf8
