.htaccess not working apache

问题

I have a server from AWS EC2 service running on Linux ubuntu and I have installed apache, php, and mysql.

I have added a .htaccess file in my document root /var/www/html.

I entered this code in it: ErrorDocument 404 /var/www/html/404.php and it is still not showing up.

I kept entered this command multiple times: sudo service httpd restart to restart the server but no changes displayed...

How can I fix this... Did I do something wrong?

Thanks in advance!

回答1:

First, note that restarting httpd is not necessary for .htaccess files. .htaccess files are specifically for people who don't have root - ie, don't have access to the httpd server config file, and can't restart the server. As you're able to restart the server, you don't need .htaccess files and can use the main server config directly.

Secondly, if .htaccess files are being ignored, you need to check to see that AllowOverride is set correctly. See http://httpd.apache.org/docs/2.4/mod/core.html#allowoverride for details. You need to also ensure that it is set in the correct scope - ie, in the right block in your configuration. Be sure you're NOT editing the one in the block, for example.

Third, if you want to ensure that a .htaccess file is in fact being read, put garbage in it. An invalid line, such as "INVALID LINE HERE", in your .htaccess file, will result in a 500 Server Error when you point your browser at the directory containing that file. If it doesn't, then you don't have AllowOverride configured correctly.

Enable Apache mod_rewrite module

a2enmod rewrite
add the following code to /etc/apache2/sites-available/default

AllowOverride All
Restart apache

/etc/init.d/apache2 restart

If you have tried all of the above, which are all valid and good answers, and your htaccess file is not working or being read change the directive in the apache2.conf file. Under Ubuntu the path is /etc/apache2/apache2.conf

Change the <Directory> directive pointing to your public web pages, where the htaccess file resides. Change from AllowOverride None to AllowOverride All

<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>

I had the same problem and found the answer and explanation on the Ubuntu Ask! forum https://askubuntu.com/questions/421233/enabling-htaccess-file-to-rewrite-path-not-working

For Ubuntu,
First, run this command :-

sudo a2enmod rewrite

Then, edit the file /etc/apache2/sites-available/000-default.conf using nano or vim using this command :-

sudo nano /etc/apache2/sites-available/000-default.conf

Then in the 000-default.conf file, add this after the line DocumentRoot /var/www/html. If your root html directory is something other, then write that :-

<Directory "/var/www/html">
  AllowOverride All
</Directory>

After doing everything, restart apache using the command sudo service apache2 restart

Just follow 3 steps

Enable mode_rewrite using following command

sudo a2enmod rewrite

Password will be asked. So enter your password

Update your 000-default.conf or default.conf file located at /etc/apache2/sites-available/ directory. you can not edit it directly. so use following command to open

sudo gedit /etc/apache2/sites-available/000-default.conf

Or sudo gedit /etc/apache2/sites-available/default.conf

you will get

DocumentRoot /var/www/html

DocumentRoot /var/www

line. Add following code after it.

<Directory /var/www/html/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>

Make user the directory tag path is same as shown in your file.

Restart your apache server using following command

sudo service apache2 restart

回答6:

Most probably, AllowOverride is set to None. in Directory section of apache2.conf located in /etc/apache2 folder

Try setting it to AllowOverride All

回答7:

In my experience, /var/www/ directory directive prevents subfolder virtualhost directives. So if you had tried all suggestions and still not working and you are using virtualhosts try this ;

1 - Be sure that you have AllowOverride All directive in /etc/apache2/sites-available/example.com.conf

2 - Check /var/www/ Directory directives in /etc/apache2/apache2.conf (possibly at line 164), which looks like ;

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride None
        Require all granted
</Directory>

If there is an AllowOverride None directive change it to AllowOverride All or just escape line

By default, Apache prohibits using an .htaccess file to apply rewrite rules, so

Step 1 — Enabling mod_rewrite (if not Enabled) First, we need to activate mod_rewrite. It's available but not enabled with a clean Apache 2 installation.

$ sudo a2enmod rewrite

This will activate the module or alert you that the module is already enabled. To put these changes into effect, restart Apache.

$ sudo systemctl restart apache2

mod_rewrite is now fully enabled. In the next step we will set up an .htaccess file that we'll use to define rewrite rules for redirects.

Step 2 — Setting Up .htaccess Open the default Apache configuration file using nano or your favorite text editor.

$ sudo nano /etc/apache2/sites-available/000-default.conf

Inside that file, you will find a block starting on the first line. Inside of that block, add the following new block so your configuration file looks like the following. Make sure that all blocks are properly indented.

/etc/apache2/sites-available/000-default.conf

<VirtualHost *:80>
    <Directory /var/www/html>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted
    </Directory>

    . . . 
</VirtualHost>

Save and close the file. To put these changes into effect, restart Apache.

$ sudo systemctl restart apache2

Done. Your .htacess should work. This link may actually help somebody https://www.digitalocean.com/community/tutorials/how-to-rewrite-urls-with-mod_rewrite-for-apache-on-ubuntu-16-04
