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 />
OptionsFollowSymLinks
AllowOverrideNone
Orderdeny,allow
Denyfromall
</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 />
OptionsFollowSymLinks
AllowOverrideNone
Orderdeny,allow
Allowfromall
</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:
#
#Ifyouwishhttpdtorunasadifferentuserorgroup,youmustrun
#httpdasrootinitiallyanditwillswitch.
#
#User/Group:Thename(or#number)oftheuser/grouptorunhttpdas.
#Itisusuallygoodpracticetocreateadedicateduserandgroupfor

# This is the group your web server runs as.

$webservergroup = 'daemon';6.3 Change the ownership by the chown command as below:
Chown -R root:daemon bugs/
