MySQL my.cnf 文件 - 找到没有前面组的选项

我正在尝试远程连接到 Ubuntu 中的数据库，但在尝试时收到错误消息mysql -u root -p:

在配置文件中找到没有前面组的选项：/etc/mysql/my.cnf 第 1 行

my.cnf 看起来像：

[mysqld]
user        = mysql
socket      = /var/run/mysqld/mysqld.sock
port        = 3306
basedir     = /usr
datadir     = /var/lib/mysql
tmpdir      = /tmp
bind-address        =  0.0.0.0
key_buffer      = 16M
max_allowed_packet  = 16M
thread_stack        = 192K
thread_cache_size       = 8
myisam-recover         = BACKUP
query_cache_limit   = 1M
query_cache_size        = 16M
log_error                = /var/log/mysql/error.log
expire_logs_days    = 10
max_binlog_size         = 100M

[client]
port        = 3306
socket      = /var/run/mysqld/mysqld.sock

[mysqld_safe]
socket      = /var/run/mysqld/mysqld.sock
nice        = 0

[mysqldump]
quick
quote-names
max_allowed_packet  = 16M

[mysql]

[isamchk]
key_buffer      = 16M

缺少配置标头

只需添加[mysqld]作为第一行/etc/mysql/my.cnf file.

Example

[mysqld]
default-time-zone = "+08:00"

然后，记得重新启动 MySQL 服务。

sudo mysqld stop
sudo mysqld start
