7. 配置默认编码为UTF8
vim /etc/my.cnf配置文件，在[mysqld]下添加编码配置，如下所示：
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'

# 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
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.

# read_rnd_buffer_size = 2M
