1.首先確認(rèn)服務(wù)器出于安全的狀態(tài)蚁吝,也就是沒有人能夠任意地連接MySQL數(shù)據(jù)庫懂版。
因?yàn)樵谥匦略O(shè)置MySQL的root密碼的期間笋轨,MySQL數(shù)據(jù)庫完全出于沒有密碼保護(hù)的
狀態(tài)下聂沙,其他的用戶也可以任意地登錄和修改MySQL的信息√鼻蓿可以采用將MySQL對(duì)
外的端口封閉蜒蕾,并且停止Apache以及所有的用戶進(jìn)程的方法實(shí)現(xiàn)服務(wù)器的準(zhǔn)安全
狀態(tài)。最安全的狀態(tài)是到服務(wù)器的Console上面操作焕阿,并且拔掉網(wǎng)線咪啡。
2.修改MySQL的登錄設(shè)置:
vi /etc/my.cnf
在[mysqld]的段中加上一句:skip-grant-tables例如:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-grant-tables
保存并且退出vi。
3.重新啟動(dòng)mysqld(mysql)
/etc/init.d/mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
4.登錄并修改MySQL的root密碼
/usr/bin/mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 3 to server version: 3.23.56
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> USE mysql ;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> UPDATE user SET Password = password ( 'new-password' ) WHERE User = 'root' ;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 2 Changed: 0 Warnings: 0
mysql> flush privileges ;
Query OK, 0 rows affected (0.01 sec)
mysql> quit
Bye
5.將MySQL的登錄設(shè)置修改回來
將剛才在[mysqld]的段中加上的skip-grant-tables刪除
保存并且退出vi暮屡。
vi /etc/my.cnf
6.重新啟動(dòng)mysqld
/etc/init.d/mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
