修改密码 刷新权限和重启mysql
update user set password=password(‘自己的密码‘) where user=‘root‘;
flush privileges;
service mysqld restart;

删除匿名用户

在MySQL刚刚被安装后，存在用户名、密码为空的用户。这使得数据库服务器有无需密码被登录的可能性。为消除隐患，将匿名用户删除。

[root@sample ~]# mysql -u root -p　 ← 通过密码用root登录
Enter password:　 ← 在这里输入密码

Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 7 to server version: 4.1.20
Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the buffer.
mysql> select user,host from mysql.user;　 ← 查看用户信息

CentOS下开启mysql远程连接，远程管理数据库

2012-08-16 08:47:40| 分类： mysql |举报|字号 订阅
当服务器没有运行php、没装phpmyadmin的时候，远程管理mysql就显得有必要了。因为在CentOS下设置的，所以标题加上了CentOS，以下的命令在debian等系统下应该也OK。

mysql -u root -p mysql # 第1个mysql是执行命令，第2个mysql是系统数据名称
在mysql控制台执行:

grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘远程登录的密码,可以和本地的不同‘ with grant option;
# root是用户名，%代表任意主机，‘123456‘指定的登录密码（这个和本地的root密码可以设置不同的，互不影响）
flush privileges; # 重载系统权限
exit;
允许3306端口

iptables -I INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
# 查看规则是否生效
iptables -L -n # 或者: service iptables status

# 此时生产环境是不安全的，远程管理之后应该关闭端口，删除之前添加的规则
iptables -D INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
PS，上面iptables添加/删除规则都是临时的，如果需要重启后也生效，需要保存修改:
service iptables save # 或者: /etc/init.d/iptables save
另外，
vi /etc/sysconfig/iptables # 加上下面这行规则也是可以的
-A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT

远程管理数据库的软件，win系统下可以使用SQLyog，用了几种远程软件，感觉这个用起来蛮不错的。

webmin
root
系统密码

服务器为多网卡,找出到公网的网口.利用-i [port_name]配置允许访问TCP:22和TCP:1521;其他协议及端口默认拒绝.
iptables -A INPUT -i eth1 -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -i eth1 -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -i eth1 -p tcp --dport 10000 -j ACCEPT
iptables -A INPUT -i eth1 -j DROP
运行/etc/rc.d/init.d/iptables save保存配置文件到/etc/sysconfig/iptables下

运行service iptables restart确认重启iptables后规则仍有效.

下面是nginx的配置文件已经开了ssl
