用密码控制访问apache目录

1.线索：cat /var/log/httpd/error_log
2.发现：每次登录加密目录失败后都会在error_log追加如下记录：
　　　[Sat Jun 18 02:32:16 2005] [error] [client 221.5.200.34]
　　　MySQL ERROR: Table 'test.user_info' doesn't exist
　　　（晕：居然跟mysql 有关，各位看官此时是不是有些纳闷？）
3.Google里搜寻：MySQL ERROR: Table 'test.user_info' doesn't exist
4.如下收获：

If you are trying to run mod_auth_mysql and BASIC htaccess authentication at the same time you may want to do something like so in your httpd.conf after you have mod_auth_mysql working.

<Directory />
Options All
AuthMySQLEnable off
AllowOverride All
</Directory>

This will turn it off globally. The main reason for us needing to do this is because if a client uses cpanel to create Password Protected Directories and then tries to access this protected directory you'll get something like:
[Mon May 2 10:29:48 2005] [error] MySQL ERROR: Table 'test.user_info' doesn't exist: /test
[Mon May 2 10:29:48 2005] [error] MySQL user test not found: /test
[Mon May 2 10:29:49 2005] [error] MySQL ERROR: Table 'test.user_info' doesn't exist: /test
[Mon May 2 10:29:49 2005] [error] MySQL user test not found: /test
[Mon May 2 10:29:50 2005] [error] MySQL ERROR: Table 'test.user_info' doesn't exist: /test
[Mon May 2 10:29:50 2005] [error] MySQL user test not found: /test

It automatically tries to use mod_auth_mysql as the only authentication. So turn it off globally and then in your .htaccess file turn it back on per directory as you need it.

And a good how-to on installing mod_auth_mysql with Apache 1.3 (linux) go here:

Just wanted to share this in case anyone else has run into the same problem.

Apache上访问控制的问题 RHEL4, 系统自带Apache, SELinux已关闭
我想将网站的abc目录设置成为需要输入用户名与密码后才能访问。
配置文件如下(所有配置文件的属性已经设为755,属于apache用户)，
配置完成后浏览时会显示需要输入用户和密码窗口，但是输入后也无法进入（还是显示请输入密码）。
请高手指点。

-----------------httpd.conf-----------------------
<Directory "/var/www/html/abc">
require user abc
AuthUserFile /home/user
AuthType Basic
AuthName "abc"
</Directory>
-------/home/user--------
abc:KWGk9SqLrFQdA

-------已次输入用户密码后浏览器显示的内容-------

如何把按中文安装的redhat server4 变回英文环境 LANG=en_US.UTF-8

apache根目录权限问题 httpd.conf中的配置为默认配置
DocumentRoot "/var/www/html"

下载phpMyAdmin-2.6.4-pl4.tar.gz并解压至目录/usr/local/src，
#cd /usr/local/src
#tar -zxvf phpMyAdmin-2.6.4-pl4.tar.gz
#cp -ar phpMyAdmin-2.6.4-pl4 /var/www/html/phpMyAdmin
#cd /var/www/html
#ll
drwxr-xr-x 7 52400 24067 4096 Nov 15 23:33 phpMyAdmin
#chown -R root:root /var/www/html/phpMyAdmin
#chmod 755 -R /var/www/html/phpMyAdmin
#ll
drwxr-xr-x 7 root root 4096 Nov 15 23:33 phpMyAdmin
然后在浏览器中浏览http://192.168.10.121/phpMyAdmin
报告如下提示：
You don't have permission to access /phpMyAdmin on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

问题解决：（因噎废食的解决方法）
diable 掉selinux,selinux是linux下面的安全加强，启用了该功能安全是安全了，可视很多东西一调试就出问题，建议新手还是禁用了吧。

最终解决方法：
#ls -Z
chcon -R -t -h httpd_sys_context_t phpMyAdmin
#ls -Z
对于文件或者目录的contexts不清楚可以查看一下文件：/etc/selinux/targeted/contexts/files的内容
