================mysql5.7改编码为utf8=========
网上很多都是直接改/etc/mysql/my.cnf文件配置
但是有些mysql5.7在改了/etc/mysql/my.cnf后不能正常启动
另一种方法：修改 /etc/mysql/mysql.conf.d/mysqld.cnf
#cd /etc/mysql/mysql.conf.d #vim mysqld.cnf 末尾加入 character-set-server=utf8 collation-server=utf8_general_ci skip-character-set-client-handshake 重启mysql: #cd /etc/init.d/#service mysql restart
mysql -u root -p
检查：
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/ | +--------------------------+----------------------------+
完成
只有新创建的库才支持utf8。
