当你遇到Error: ER_TRUNCATED_WRONG_VALUE_FOR_FIELD: Incorrect string value:

Error: ER_TRUNCATED_WRONG_VALUE_FOR_FIELD: Incorrect string value: '\xE6\x88\x91\xE4\xBB\xAC...' for column 'content' at row 1



这种原因是字符集编码导致的。
1、验证字符集
首先进入mysql：

mysql  -u root -p


进入之后输入以下：

show variables like '%character%';



这里是输入命令之后的视图：

mysql> show variables like '%character%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8mb4                    |
| character_set_connection | utf8mb4                    |
| character_set_database   | latin1                     |
| character_set_filesystem | binary                     |
| character_set_results    | utf8mb4                    |
| character_set_server     | latin1                     |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.01 sec)



你会看到| character_set_server | latin1 |
就是这个character_set_server等于latin1导致的错误，需要手动改文件
2、进入my.cnf

vim /etc/my.cnf



编辑my.cnf
在[mysqld]下面

character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
init_connect='SET NAMES utf8mb4'



3、重启mysql.

service mysql restart



4、再次登录mysql，查看字符集

mysql> show variables like '%character%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8mb4                    |
| character_set_connection | utf8mb4                    |
| character_set_database   | utf8mb4                    |
| character_set_filesystem | binary                     |
| character_set_results    | utf8mb4                    |
| character_set_server     | utf8mb4                    |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.01 sec)



出现以上视图你就成功一半了

5、为什么成功一半呢？
需要把已经建立好的数据库和表格全部重新建吧
