WordPress NOT FOUND the request

日期：2018年8月28日

问题：NOT FOUND the request url /wordpress/category/topic/ was not found on this server.

解决：
服务器url rewrite模块未安装或未开启。
在Nginx上为WordPress固定链接配置Rewrite： http://www.bjhee.com/nginx-rewrite.html
官方文档参考设置：https://codex.wordpress.org/Nginx

实际使用apache
解决，修改服务器/etc/httpd/conf/httpd.conf文件。安装启动rewrite模块。
1.开启rewrite_module。查找以下语句，去掉前面的#。启动。若无该语句，在LoadModule模块的最后一句后面加上。
LoadModule rewrite_module modules/mod_rewrite.so
2.修改以下代码中“ AllowOverride None” 为“ AllowOverride All”

<Directory "/var/www/html">
    #
    # 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/2.4/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 None

    #
    # Controls who can get stuff from this server.
    #
    Require all granted
</Directory>
