mysql解决中文乱码问题

1.检查确认mysql编码,正确编码如下图所示

show variables like '%char%'

2.若第一步编码异常，则修改配置文件，重启mysql服务

主要添加如下配置:

# 配置mysql服务端为utf8编码

[mysqld]

character-set-server=utf8

# 配置mysql客户端为utf8编码

[client]

default-character-set=utf8

# 配置mysql命令行操作编码

[mysql]

default-character-set=utf8

window配置文件为mysql安装目录下的my.ini，配置如下:

# For advice on how to change settings please see

# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

# *** default location during install, and will be replaced if you

# *** upgrade to a newer version of MySQL.

[mysqld]

character-set-server=utf8

# Remove leading # and set to the amount of RAM for the most important data

# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging

# changes to the binary log between backups.

# log_bin

# These are commonly set, remove the # and set as required.

basedir = D:/Application/program/database/MySql/mysql-5.7.10-winx64/

datadir = D:/Application/program/database/MySql/mysql-5.7.10-winx64/data/

# port = .....

# server_id = .....

# Remove leading # to set options mainly useful for reporting servers.

# The server defaults are faster for transactions and fast SELECTs.

# Adjust sizes as needed, experiment to find the optimal values.

# join_buffer_size = 128M

# sort_buffer_size = 2M

# read_rnd_buffer_size = 2M

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[client]

default-character-set=utf8

[mysql]

default-character-set=utf8

linux配置如下(配置文件路径为: /etc/my.cnf):

[mysqld]

basedir = /usr/local/mysql

datadir = /usr/local/mysql/data

# port = .....

# server_id = .....

socket = /tmp/mysql.sock#该mysql.sock文件必须放在一个服务端跟客户端都可以访问的位置

log_error = /usr/local/mysql/log/mysql.log#配置日志文件

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

[mysql]

socket=/tmp/mysql.sock

[mysql.server]

user=mysql

basedir=/usr/local/mysql

[mysqladmin]

socket=/tmp/mysql.sock

[mysql.server]

user=mysql

basedir=/usr/local/mysql

[safe_mysqld]

err-log=/usr/local/mysql/mysqld.log

pid-file=/usr/local/mysql/mysqld.pid

3.若表还是显示中文乱码，或者无法插入中文，则查看表DDL

show create table table_name;

保证表编码为utf8
