Apache

 Apache来实现基本的用户身份认证有很多种方式,比如最常见的txt文本和DBM格式,但在负载很重的server上-这些都不是理想的方法,文本的形式是基于平面的,性能很差而且也不安全;DBM好些但在千或万级用户时还是力不从心,于是用database做后台存储则是很好的方法-比平面搜索更有效而且安全,用户口令以DES加密形式存储在数据库的表中。

  这种实现要归功于Apache本身出色的模块化结构--以及开放的DSO方式,可以使开发人员完成大量的第三方模块,并扩充Apache的功能。我在本文中只写了用Mysql做后台存储--此外还可用Postgresql,Oracle等来完成,原理一样-都是用各自的模块。

  让我们开始吧--先去modules.apache.org找到mod_auth_mysql--会有两个我们要用DSO那个-事实上直接去ftp://ftp.kcilink.com/pub/下一个mod_auth_mysql.c.gz就行-好-把它解开是一个mod_auth_mysql.c-好-我们用apxs来生成DSO模块(前题是你用DSO模式编译的Apache)--apxs -c -i -a -L/usr/local/lib/mysql -lmysqlclient >-lm mod_auth_mysql.c即可--这里注意一定要这么写---L/usr/local/lib/mysql是mysql的客户库位置,我假定mysql是用的缺省安装)---如果不加在起动Apache时会报错-无法装载此模块。

  好了看看httpd.conf中应该有LoadModule mysql_auth_module libexec/mod_auth_mysql.so和AddModule mod_auth_mysql.c这两句了,重起Apache也不应该有问题。

  然后我们进入mysql,mysql>create database auth;

mysql>use auth;
mysql> create table mysql_auth (
-> user_name char(20) not null,
-> user_passwd char(25),
-> groups char(25),
-> primary key (username) );


  注意字段名一定是user_name和user_passwd这个。再插入几条记录:

mysql> insert into mysql_auth values
('xingfei2',encrypt("abcde"),'xingfei');
Query OK, 1 row affected (0.00 sec)
mysql> insert into mysql_auth values
('xingfei',encrypt("abcde"),'xingfei');
Query OK, 1 row affected (0.00 sec)


  这里abcde是口令-用encrypt函数来进行加密,用的是DES算法-这是和unix的password等同的算法-而不是mysql本身加密的password()函数。

  最后在要保护的目录里建一个.htaccess(别忘了把AllowOverride all打开)内容如下:

authname "xingfei"
authtype basic
AuthMySQLHost localhost ---mysql主机名
authmysqluser root ---mysql用户
authmysqlpassword abc ---mysql用户的口令
AuthMySQLDB auth ---用户所用的库-也就是我们建的库
AuthMySQLUserTable mysql_auth ---所用的表
AuthMySQLGroupField groups ---用户组的字段名
require group xingfei
require user xingfei


  可以把用户都放在一个组里-只要是这个组里的用户即可通过认证,也可require单个或多个用户

In Ubuntu systems, the root user is usually disabled. To activate the root user, you can use the passwd command to set a password and then use the su- command to log in as root. The root user is a user with unrestricted system administrative rights. He has permissions to access and modify files, user management, software installation and removal, and system configuration changes. There are obvious differences between the root user and ordinary users. The root user has the highest authority and broader control rights in the system. The root user can execute important system commands and edit system files, which ordinary users cannot do. In this guide, I'll explore the Ubuntu root user, how to log in as root, and how it differs from a normal user. Notice

What is sudo and why is it important? What is sudo and why is it important? Feb 21, 2024 pm 07:01 PM

sudo (superuser execution) is a key command in Linux and Unix systems that allows ordinary users to run specific commands with root privileges. The function of sudo is mainly reflected in the following aspects: Providing permission control: sudo achieves strict control over system resources and sensitive operations by authorizing users to temporarily obtain superuser permissions. Ordinary users can only obtain temporary privileges through sudo when needed, and do not need to log in as superuser all the time. Improved security: By using sudo, you can avoid using the root account during routine operations. Using the root account for all operations may lead to unexpected system damage, as any mistaken or careless operation will have full permissions. and

Users only need to click once to automatically eliminate the background and highlight the main body of the picture, making it easier for users to perform subsequent operations. The whole step is very simple. The user imports the picture in the new layout application, and then clicks the "removebackground" button on the toolbar to delete the background in the picture. The user can also use a rectangle to select the area to remove the background.
