through mysql.sock_MySQL报错的解决'Can't connect to local MySQL server through socket '/tmp/mysql.sock'...

最近在linux上面用django写一个小网站 ,数据库用的是mysql,但是突然有一天,出现了奇怪的问题,报错:

mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

然后我去看这个文件'/var/lib/mysql/mysql.sock' ,但是没有找到,我就有点不明白了,然后想起可能是mysql的服务mysqld没有启动,因为mysql  -u root -p这个命令还是能用的,所以赶紧查看了一下service mysqld status 是什么状态,才看到原来没有启动,然后就没有问题了。

启动mysql 报错:

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)

1、先查看 /etc/rc.d/init.d/mysqld status 看看mysql是否已经启动.另外看看是不是权限问题.

2、确定你的mysql.sock是不是在那个位置,mysql -u 你的mysql用户名 -p -S /var/lib/mysql/mysql.sock

3、试试:service mysqld start

4、如果是权限问题,则先改变权限 #chown -R mysql:mysql /var/lib/mysql

[root@localhost ~]# /etc/init.d/mysqld start启动 MySQL: [ 确定 ][root@localhost ~]# mysql -u root -p

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)原因是,/var/lib/mysql 的访问权限问题。

shell> chown -R mysql:mysql /var/lib/mysql

接着启动服务器

shell> /etc/init.d/mysql start

服务器正常启动后察看 /var/lib/mysql 自动生成mysql.sock文件。

但是我的问题仍然没有得到解决。

问题终于解决:方法:修改/etc/my.conf:[mysqld]datadir=/usr/local/mysql/datasocket=/var/lib/mysql/mysql.sock

[mysql.server]user=mysqlbasedir=/usr/local/mysql

If there is not currently a section called [client], add one at the bottom of the file and copy the socket= line under the [mysqld] section such as:

[client]socket=/var/lib/mysql/mysql.sock

发现依旧如此,运行/etc/init.d/mysql start报错:Starting MySQLCouldn't find MySQL manager or server是mysqld服务没启,运行/usr/local/mysql/bin/mysqld_safe &

问题解决。

执行 PHP 时出现类似这样的错误信息:

Warning: MySQL Connection Failed: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111) in /home/httpd/html/show.php on line 9

请将 /tmp/mysql.sock link 到 /var/lib/mysql 目录里即可:

linux# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
