更改配置文件

更改 /etc/my.cnf.d/client.cnf 文件
[client] 下加一行配置 default-character-set=utf8
样例：

#
# These two groups are read by the client library
# Use it for options that affect all clients, but not the server
#


[client]
default-character-set = utf8

# This group is not read by mysql client library,
# If you use the same .cnf file for MySQL and MariaDB,
# use it for MariaDB-only client options
[client-mariadb]

更改 /etc/my.cnf.d/mysql-clients.cnf 文件
[mysql] 下加一行配置 default-character-set=utf8
样例：

#
# These groups are read by MariaDB command-line tools
# Use it for options that affect only one utility
#

[mysql]
default-character-set = utf8

[mysql_upgrade]

[mysqladmin]

[mysqlbinlog]

[mysqlcheck]

[mysqldump]

[mysqlimport]

[mysqlshow]

[mysqlslap]

更改 /etc/my.cnf.d/server.cnf 配置
[mysqld] 下加配置
collation-server = utf8_general_ci
init-connect='SET NAMES utf8'
character-set-server = utf8
sql-mode = TRADITIONAL
样例：

#
# These groups are read by MariaDB server.
# Use it for options that only the server (but not clients) should see
#
# See the examples of server my.cnf files in /usr/share/mysql/
#

# this is read by the standalone daemon and embedded servers
[server]

# this is only for the mysqld standalone daemon
[mysqld]
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8

sql-mode = TRADITIONAL

# this is only for embedded server
[embedded]

# This group is only read by MariaDB-5.5 servers.
# If you use the same .cnf file for MariaDB of different versions,
# use this group for options that older servers don't understand
[mysqld-5.5]

# These two groups are only read by MariaDB servers, not by MySQL.
# If you use the same .cnf file for MySQL and MariaDB,
# you can put MariaDB-only options here
[mariadb]

[mariadb-5.5]
