MYSQL 修改字符集

1.暂时修改
 set names utf8
2.永久修改
 mysqld下加
 character_set_server = utf8

 MariaDB [(none)]> show variables like ‘%char%‘;
 +--------------------------+-------------------------------------------------------+
 | Variable_name            | Value                                                 |
 +--------------------------+-------------------------------------------------------+
 | character_set_client     | latin1                                                |
 | character_set_connection | latin1                                                |
 | character_set_database   | utf8                                                  |

 | character_sets_dir       | /var/soft/mariadb-5.5.50-linux-x86_64/share/charsets/ |

 client和mysql下加
 default-character-set = utf8

 | character_set_client     | latin1                                                |
 | character_set_connection | latin1                                                |
