1.关闭mysql服务

使用以下命令可以查看MySQL服务的状态:

service mysql status

2.

admin@xx:/etc/mysql/conf.d$ service mysql stop

admin@xx:/etc$ cd mysql

admin@xx:/etc/mysql$ ls

conf.d debian-start my.cnf.fallback mysql.conf.d

debian.cnf my.cnf mysql.cnf

admin@xx:/etc/mysql$ vim my.cnf

#发现是引用其他cnf文件:conf.d下的mysql.cnf,和mysql.conf.d下的mysqld.cnf

admin@xx:/etc/mysql$ cd mysql.conf.d/

admin@xx:/etc/mysql/mysql.conf.d$ ls

mysqld.cnf mysqld_safe_syslog.cnf

admin@xx:/etc/mysql/mysql.conf.d$ sudo vim mysqld.cnf

[sudo] admin 的密码:

在[mysqld]下追加:

character-set-server=utf8

(编辑可参考vim使用技巧)

admin@xx:/etc/mysql/mysql.conf.d$ cd ..

admin@xx:/etc/mysql$ ls

conf.d debian-start my.cnf.fallback mysql.conf.d

debian.cnf my.cnf mysql.cnf

admin@xx:/etc/mysql$ cd conf.d/

admin@xx:/etc/mysql/conf.d$ ls

mysql.cnf mysqldump.cnf

admin@xx:/etc/mysql/conf.d$ sudo vim mysql.cnf

在[mysql]下追加:

default-character-set=utf8

3.启动mysql服务

admin@xx:/etc/mysql/conf.d$ service mysql start

4.登陆mysql,查看 mysql> \s
