ubuntu14.04.1启动mysql出错

ubuntu版本为14.04.1,apt-get install mysql 启动出错: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

my.cnf配置如下:
#

The MySQL database server configuration file.

#

You can copy this to one of:

- "/etc/mysql/my.cnf" to set global options,

- "~/.my.cnf" to set user-specific options.

One can use all long options that the program supports.

Run program with --help to get a list of available options and with

--print-defaults to see which it would actually understand and use.

#

For explanations see

http://dev.mysql.com/doc/mysql/en/server-system-variables.html

This will be passed to all mysql clients

It has been reported that passwords should be enclosed with ticks/quotes

escpecially if they contain "#" chars...

Remember to edit /etc/mysql/debian.cnf when changing the socket location.

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

Here is entries for some specific programs

The following values assume you have at least 32M ram

This was formally known as [safe_mysqld]. Both versions are currently parsed.

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

[mysqld]
#

* Basic Settings

#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
#

Instead of skip-networking the default is now to listen only on

localhost which is more compatible and is not less secure.

bind-address = 127.0.0.1
#

* Fine Tuning

#
key_buffer = 16M
max_allowed_packet = 16M
thread_stack = 192K
thread_cache_size = 8

This replaces the startup script and checks MyISAM tables if needed

the first time they are touched

myisam-recover = BACKUP
#max_connections = 100
#table_cache = 64
#thread_concurrency = 10
#

* Query Cache Configuration

#
query_cache_limit = 1M
query_cache_size = 16M
#

* Logging and Replication

#

Both location gets rotated by the cronjob.

Be aware that this log type is a performance killer.

As of 5.1 you can enable the log at runtime!

#general_log_file = /var/log/mysql/mysql.log
#general_log = 1
#

Error log - should be very few entries.

#
log_error = /var/log/mysql/error.log
#

Here you can see queries with especially long duration

#log_slow_queries = /var/log/mysql/mysql-slow.log
#long_query_time = 2
#log-queries-not-using-indexes
#

The following can be used as easy to replay backup logs or for replication.

note: if you are setting up a replication slave, see README.Debian about

other settings you may need to change.

#server-id = 1
#log_bin = /var/log/mysql/mysql-bin.log
expire_logs_days = 10
max_binlog_size = 100M
#binlog_do_db = include_database_name
#binlog_ignore_db = include_database_name
#

* InnoDB

#

InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.

Read the manual for more InnoDB related options. There are many!

#

* Security Features

#

Read the manual, too, if you want chroot!

chroot = /var/lib/mysql/

#

For generating SSL certificates I recommend the OpenSSL GUI "tinyca".

#

ssl-ca=/etc/mysql/cacert.pem

ssl-cert=/etc/mysql/server-cert.pem

ssl-key=/etc/mysql/server-key.pem

[mysqldump]
quick
quote-names
max_allowed_packet = 16M

[mysql]
#no-auto-rehash # faster start of mysql but no tab completition

[isamchk]
key_buffer = 16M

#

* IMPORTANT: Additional settings that can override those from this file!

The files must end with '.cnf', otherwise they'll be ignored.

#
!includedir /etc/mysql/conf.d/

在/var/run/mysqld/中没有任何文件,/var/lib/mysql/下为
debian-5.5.flag ibdata1 ib_logfile0 ib_logfile1 mysql performance_schema
找不到mysqld.sock文件。
