本文章向大家介绍mysql中文乱码记录,主要包括mysql中文乱码记录使用实例、应用技巧、基本知识点总结和需要注意事项,具有一定的参考价值,需要的朋友可以参考一下。

0.中文乱码

1.查看mysql中表结构

show create table log_data

charset为utf8,代码端:通过gorm修改 在创建表时候修改(这里在连接数据库时已经修改过了,但是没有修改成功

//db为已经连接好的gorm数据
err := db.Set("gorm:table_options", "ENGINE=InnoDB DEFAULT CHARSET=utf8").CreateTable(&LogData{}).Error

2.再次查看

show create table table_name

已经修改成功

但是还是乱码。在本地获取数据库内容,可以正常显示,所以不是字符问题。

查看表中数据段

show variables like '%char%';

3.修改mysql配置文件

修改配置

#1.(容器创建的mysql)进入容器
cd /etc/mysql

#先下载vim编辑器,然后编辑
apt-get update
apt-get install vim


#编辑/etc/mysql/my.cnf

#mysql的配置文件如下

# The MySQL  Server configuration file.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
#log-error      = /var/log/mysql/error.log
# By default we only accept connections from localhost
#bind-address   = 127.0.0.1
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character_set_server=utf8
init_connect='SET NAMES utf8'
max_allowed_packet = 20M

[mysql]
default-character-set = utf8

[mysql.server]
default-character-set = utf8

[mysqld_safe]
default-character-set = utf8

[client]
default-character-set = utf8


当然也可以在外面编辑好

#宿主机复制到容器内 mysql为容器名称
docker cp /root/my.cnf mysql:/etc/mysql/my.cnf

#容器内复制到宿主机中   
docker cp mysql:/etc/mysql/my.cnf /root/my.cnf

为什么要修改/etc/mysql/my.cnf的文件

我用docker创建mysql5.7时候/etc/mysql/路径下没有my.cnf,然后自己创建了my.cnf,修改后需要重启容器

4.查看修改后的mysql

查看表数据

已正常显示
