1.安装好Mysql后，部署项目，发现最终测试数据库中存入的数据乱码。登录查看mysql编码集：
mysql> show variables like '%character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
原来服务器编码集为latin1,需要修改编码集，进入/etc/my.inf
先关闭服务器
[root@izm5e0lvzs7172fyshy9zdz etc]# service mysqld stop ;
Redirecting to /bin/systemctl stop mysqld.service
在进入vi:
[root@izm5e0lvzs7172fyshy9zdz etc]# vi /etc/my.cnf
[client]
default-character-set=utf8
[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci
保存后启动Mysql服务器：
[root@izm5e0lvzs7172fyshy9zdz etc]# systemctl restart mysqld
重新查看：
mysql> show variables like '%character%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
然后重测不乱码
