【MySQL】Mariadb字符集

Mariadb字符集

如果不设置字符集，可以查看mariadb的字符集的默认设置是latin1。

如下命令,查看Mariadb的默认配置:

[ ~]# /usr/local/mysql/bin/mysqld --verbose --help |grep character-set-server
2019-09-23 16:10:05 0 [Note] Plugin 'FEEDBACK' is disabled.
  -C, --character-set-server=name 
character-set-server                                       latin1

修改Mariadb的字符集为utf8，国际统一标准，配置如下:

[ ~]# vi /etc/my.cnf 
[mysqld]
datadir=/u01/data/
socket=/tmp/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character-set-server = utf8

[mysqld_safe]
log-error=/u01/data/mysqld.log
pid-file=/tmp/mysqld.pid

重启服务，如下:

[ ~]# service mysqld restart

最终，服务器统一为utf8,如下:

[ ~]# mysql -uroot -p
