mysql,Mysqldump,Mysqladmin,php鏈接mysql服務常會提示下面錯誤:html
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/<span class='wp_keywordlink_affiliate'><a href="http://www.aiezu.com/tag/mysql-2" title="查看 mysql 中的所有文章" target="_blank">mysql</a></span>/mysql.sock' (2)mysql

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)shell |
這是因爲修改mysql服務的了socket文件mysql.sock位置,而致使沒法經過mysql socket文件鏈接到mysql服務引發的,具體解決辦法以下:
一、查看mysql服務的socket文件位置:
mysql socket文件的位置是在/etc/my.cnf中設置的,cat /etc/my.cnf內容以下:服務器
[mysqld] datadir=/storage/db/mysql socket=/storage/db/mysql/mysql.sock user=mysqlsocket
1spa 2server 3htm 4 |
[mysqld] datadir=/storage/db/mysql socket=/storage/db/mysql/mysql.sock user=mysql |
其中socket等於的路徑就是socket文件的位置,咱們只要修改my.cnf文件,告訴mysql,mysqldump,mysqladmin mysql服務的socket位置在哪裏就能夠。
二、修改my.cnf文件:
在/etc/my.cnf文件中添加以下內容,並重啓mysqls服務,便可解決mysql,mysqldump,mysqladmin的「Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'」問題:
[mysqld] datadir=/storage/db/mysql socket=/storage/db/mysql/mysql.sock [mysql] socket=/storage/db/mysql/mysql.sock [mysqldump] socket=/storage/db/mysql/mysql.sock [mysqladmin] socket=/storage/db/mysql/mysql.sock
1 2 3 4 5 6 7 8 9 10 11 12 |
[mysqld] datadir=/storage/db/mysql socket=/storage/db/mysql/mysql.sock
[mysql] socket=/storage/db/mysql/mysql.sock
[mysqldump] socket=/storage/db/mysql/mysql.sock
[mysqladmin] socket=/storage/db/mysql/mysql.sock |
啓動mysql 報錯:
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)
一、先查看 /etc/rc.d/init.d/mysqld status 看看m y s q l 是否已經啓動.
另外看看是否是權限問題.
二、肯定你的mysql.sock是否是在那個位置,
mysql -u 你的mysql用戶名 -p -S /var/lib/mysql/mysql.sock
三、試試:service mysqld start
四、若是是權限問題,則先改變權限 #chown -R mysql:mysql /var/lib/mysql
[root@localhost ~]# /etc/init.d/mysqld start
啓動 MySQL: [ 肯定 ]
[root@localhost ~]# mysql -uroot -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
緣由是,/var/lib/mysql 的訪問權限問題。
shell> chown -R mysql:mysql /var/lib/mysql
接着啓動服務器
shell> /etc/init.d/mysql start
服務器正常啓動後察看 /var/lib/mysql 自動生成mysql.sock文件。
可是個人問題仍然沒有獲得解決。
問題終於解決:
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
發現依舊如此,運行/etc/init.d/mysql start報錯: Starting MySQLCouldn't find MySQL manager or server 是mysqld服務沒啓,運行/usr/local/mysql/bin/mysqld_safe &問題解決。
