MAC, 404 appears when configuring the system's built-in apache virtual host

Question

As the title states, the following are the main codes of my various configuration files. Please help me check them!
The following are some codes of httpd.conf:

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/usr"
...
#
# Deny access to the entirety of your server's filesystem. You must
# explicitly permit access to web content directories in other 
# <Directory> blocks below.
#
<Directory />
    Options  Indexes  FollowSymLinks
    AllowOverride None
    Allow from all 
</Directory>
...
#
# DocumentRoot: The directory out of which you will serve your
# documents. By default, all requests are taken from this directory, but
# symbolic links and aliases may be used to point to other locations.
#
DocumentRoot "/Users/bjhl/myServer"
<Directory "/Users/bjhl/myServer">
    #
    # 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 FollowSymLinks Multiviews
    MultiviewsMatch Any
    
    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   AllowOverride FileInfo AuthConfig Limit
    #
    AllowOverride None

    #
    # Controls who can get stuff from this server.
    #
    Require all granted

</Directory>
...

The following is httpd-vhosts.conf:

<VirtualHost *:80>
    ServerAdmin www.YYServer.com
    DocumentRoot "Users/bjhl/myServer"
    ServerName www.YYServer.com
    ServerAlias YYServer
    ErrorLog "/private/var/log/apache2/dummy-host.example.com-error_log"
    CustomLog "/private/var/log/apache2/dummy-host.example.com-access_log" common
    <Directory "/Users/bjhl/myServer">
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Require all granted
    </Directory>
</VirtualHost>

Finally hosts:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1    localhost
127.0.0.1    www.YYServer.com
255.255.255.255    broadcasthost
::1             localhost 

Answer 1

It’s sorted, but I don’t know why it didn’t work once the virtual host was introduced. In the end, I didn’t configure the virtual host. In fact, the solution is very simple. The modified part is pasted as follows:

#
# Deny access to the entirety of your server's filesystem. You must
# explicitly permit access to web content directories in other 
# <Directory> blocks below.
#
<Directory />
    AllowOverride none
    Require all granted
</Directory>
...
DocumentRoot "/Users/bjhl/myServer"
<Directory "/Users/bjhl/myServer">
    #
    # 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 Multiviews
    MultiviewsMatch Any

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

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

In addition, we need to

LoadModule php5_module libexec/apache2/libphp5.so

Uncomment this line of code and enter it in the terminal

cd /etc
sudo cp php.ini.default php.ini

That’s it
