开启Apache mod_rewrite模块（解决404 Not Found）

网站搭建完成了，进入登录界面就是访问不了。

原因大概是没有开启Apache mod_rewrite模块，或者没有配置完全。

步骤1：

启用mod_rewrite模块
在conf目录的httpd.conf文件中找到

LoadModule rewrite_module modules/mod_rewrite.so

将这一行前面的#去掉。

步骤2：

<Directory "/var/www/myweb">

#
# Possible values for the Options directive are "None", "All",
# or any combination of:
#   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important.  Please see
# http://httpd.apache.org/docs/2.2/mod/core.html#options
# for more information.
#
    Options Indexes FollowSymLinks

#
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
#   Options FileInfo AuthConfig Limit
#
AllowOverride All

#
# Controls who can get stuff from this server.
#
    Order allow,deny
    Allow from all

</Directory>

步骤3：

重新启动apache

service httpd restart

如此便可以访问了页面了，.htaccess文件在所有的子页面都有效了。

404Not Found问题解决了。
