mysqlsock錯(cuò)誤處理_MySQL

Fedora8啟動(dòng)mysql 報(bào)錯(cuò)：

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m y s q l 是否已經(jīng)啟動(dòng).

另外看看是不是權(quán)限問(wèn)題.

2、確定你的mysql.sock是不是在那個(gè)位置，

mysql -u 你的mysql用戶(hù)名-p -S /var/lib/mysql/mysql.sock

3、試試：service mysqld start

4、如果是權(quán)限問(wèn)題，則先改變權(quán)限#chown -R mysql:mysql /var/lib/mysql

[root@localhost ~]# /etc/init.d/mysqld start

啟動(dòng)MySQL：[ 確定]

[root@localhost ~]# mysql -uroot -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 的訪(fǎng)問(wèn)權(quán)限問(wèn)題。

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

接著啟動(dòng)服務(wù)器

shell> /etc/init.d/mysql start

服務(wù)器正常啟動(dòng)后察看/var/lib/mysql 自動(dòng)生成mysql.sock文件。

但是我的問(wèn)題仍然沒(méi)有得到解決。

問(wèn)題終于解決：

方法： 修改/etc/my.conf:

[mysqld]

datadir=/usr/local/mysql/data

socket=/var/lib/mysql/mysql.sock

[mysql.server]

user=mysql

basedir=/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

發(fā)現(xiàn)依舊如此，運(yùn)行/etc/init.d/mysql start報(bào)錯(cuò)：Starting MySQLCouldn't find MySQL manager or server

是mysqld服務(wù)沒(méi)啟，運(yùn)行/usr/local/mysql/bin/mysqld_safe &

問(wèn)題解決。
