  修改mysql配置文件

vim $PREFIX/etc/my.cnf

配置文件

# use it for options that affect everything
[client]
default_character_set = utf8
[client-server]
#[mysqld]
#innodb_force_recovery = 6
#innodb_purge_threads = 1
#innodb_use_sys_malloc = 1
#feedback = ON
# include all files from the config directory
!includedir /data/data/com.termux/files/usr/etc/my.cnf.d
[mysqld]
default_storage_engine = INNODB
character_set_server = utf8
collation_server=utf8_general_ci

• 设置完后，重启mysql 创建的数据库与表都用utf8

  
  
  

  设置后

• 查询语句带中文也可以正常显示了
