apache http 403 Forbidden error解决办法

 

在配置Linux的 Apache服务时，经常会遇到http403错误，我今天配置测试时也出现了，最后解决了，总结了一下。http 403错误是拒绝访问的意思，有很多原因的。我总结的主要有4种原因！

1. 访问的文档权限不够。要755以上权限。解决方法：用命令chmod 755 /var/www/ 或其他相应目录。

2. SELinux或防火墙的原因。解决方法：先关闭SELinux和让防火墙通过WWW服务。

3. 虚拟主机配置错误。解决方法：重新配置虚拟主机或暂时关闭。

4. alias指令配置错误。(alias语法：Alias URL-path file-path|directory-path)

   解决方法如下： 打开apache的配置文件httpd.conf，查看所有的alias指令，若指令中的URL-path末尾包含/，则file-path或dir-path的末尾也需要包含/，如下所示：

alias /server1   /var/server1 //正确

alias /server1/ /var/server1/ //正确

alias /server1/ /var/server1 //错误

5. DocumentRoot的设置。解决方法如下：

打开 apache的配置文件httpd.conf，找到这段代码：

<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>

有时候由于配置了php后，这里的“Deny from all”已经拒绝了一切连接。把该行改成“allow from all”，修改后的代码如下，问题解决。

<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Allow from all
</Directory>

6. For bugzilla installation

You should check the user in httpd.conf and localconfig, and make sure the same user in those two files:

6.1 For httpd.conf as below:

#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.
#
# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
#
User daemon
Group daemon

6.2 For localconfig

# This is the group your web server runs as.
# If you have a Windows box, ignore this setting.
# If you do not have access to the group your web server runs under,
# set this to "". If you do set this to "", then your Bugzilla installation
# will be _VERY_ insecure, because some files will be world readable/writable,
# and so anyone who can get local access to your machine can do whatever they
# want. You should only have this set to "" if this is a testing installation
# and you cannot set this up any other way. YOU HAVE BEEN WARNED!
# If you set this to anything other than "", you will need to run checksetup.pl
# asroot, or as a user who is a member of the specified group.
$webservergroup = 'daemon';

 

6.3 Change the ownership by the chown command as below:

Chown -R root:daemon bugs/
