使用MySQL時遇到的問題整理
1 ERROR 2002(HY000): Can't connect to local MySQL server through socket' /var/lib/mysql/mysql.sock'(2)
未啟動MySQL MySQL的問題
2 ERROR 1045(28000): Access denied for user 'root'@'localhost' (using password: NO)
密碼錯了，修改root用戶的密碼：
2.1 方法一
mysqladmin -uroot -ppassword 'newpassword'
2.2 方法二 www.2cto.com
# /etc/init.d/mysql stop
# mysqld_safe--user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE userSET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSHPRIVILEGES;
mysql> quit
# /etc/init.d/mysqlrestart
# mysql -uroot -p
Enter password: <輸入新設的密碼newpassword>
3 Can'tconnect to MySQL server on '192.168.10.31' (10060)
IP寫錯了, 或者端口沒有開放.
4 ERROR 1130:Host '192.168.1.3' is not allowed to connect to this MySQL server
4.1 改表法
在localhost的那台電腦，登入mysql後，更改"mysql"數據庫裡的"user"表裡的"host"項，從"localhost"改成"%" www.2cto.com
mysql -u root -p
mysql> use mysql;
mysql> update userset host = '%' where user = 'root';
mysql> select host,user from user;
4.2 授權法
mysql> grant all privilegeson *.* to 'yourname'@'%' identified by 'youpasswd';
Query OK, 0 rowsaffected (0.05 sec)
mysql> flushprivileges;
Query OK, 0 rowsaffected (0.06 sec)
mysql> exit
