我收到以下错误：
error: Found option without preceding group in config file: /etc/my.cnf at line: 1 Fatal error in defaults handling. Program aborted 这里是我的/etc/my.cnf文件：
[root@host backup]#cat /etc/my.cnf max_allowed_packet=100M datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Default to using old password format for compatibility with mysql 3.x # clients (those using the mysqlclient10 compatibility package). old_passwords=1 [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [mysqldump] max_allowed_packet=100M
将[mysqld]添加为my.cnf文件的第一行。
