操作系统的环境:Ubuntu 12.10
之前数据库是好的,因为我想把它设置远程连接数据库
具体是执行了GRANT ALL PRIVILEGES ON *.* TO root @'%' IDENTIFIED BY 'mysql';
后面把数据库重启,运行 mysql -uroot -pmysql,报错如下:

/var/run/mysqld目录下是不存在mysqld.sock文件的,整个盘符下都没有这个文件。

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql startSince the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start mysql
start: Job failed to start不晓得怎么就启动不了了,看报错日志也看不懂
