Get the path of running Apache

    $ ps -ef | grep apache
    apache   12846 14590  0 Oct20 ?        00:00:00 /usr/sbin/apache2

Append `-V` argument to the path 

    $ /usr/sbin/apache2 -V | grep SERVER_CONFIG_FILE
    -D SERVER_CONFIG_FILE=&quot;/etc/apache2/apache2.conf&quot;

Reference:  
http://commanigy.com/blog/2011/6/8/finding-apache-configuration-file-httpd-conf-location

See http://wiki.apache.org/httpd/DistrosDefaultLayout for discussion of where you might find Apache httpd configuration files on various platforms, since this can vary from release to release and platform to platform. The most common answer, however, is either /etc/apache/conf or /etc/httpd/conf

Generically, you can determine the answer by running the command:

&gt; httpd -V

(That&#39;s a capital V). Or, on systems where httpd is renamed, perhaps `apache2ctl -V`

This will return various details about how httpd is built and configured, including the default location of the main configuration file.

One of the lines of output should look like:

&gt; -D SERVER_CONFIG_FILE=&quot;conf/httpd.conf&quot;

which, combined with the line:

&gt; -D HTTPD_ROOT=&quot;/etc/httpd&quot;

will give you a full path to the default location of the configuration file


I came across [this example][1] in the Matplotlib website. I was wondering if it was possible to increase the figure size.

I tried with

    f.figsize(15,15)

but it does nothing.

How do I change the figure size with subplots?

I&#39;m running ActiveState&#39;s 32 bit [ActivePerl][1] 5.14.2 on Windows 7. I wanted to mess around with a Git pre-commit hook to detect programs being checked in with syntax errors. (Somehow I just managed to do such a bad commit.) So as a test program I randomly jotted this:

    use strict;
    use warnings;

    Syntax error!

    exit 0;

However, it compiles and executes with no warnings, and errorlevel is zero on exit. How is this valid syntax?

I need to create a script that automatically inputs a password to OpenSSH `ssh` client.

Let&#39;s say I need to SSH into `myname@somehost` with the password `a1234b`.

I&#39;ve already tried...

    #~/bin/myssh.sh
    ssh myname@somehost
    a1234b

...but this does not work.

How can I get this functionality into a script?

I know an `.so` file is a kind of dynamic library (lots of threads can share such libraries so there is no need to have more than one copy of it in memory). But what is the difference between `.a` and `.la`? Are these all static libraries?

If dynamic libs have big advantages over static ones, why there are still lots of static libraries? When should I try to build code into `.so` or `.a`?

I have a elastic beanstalk linux-tomcat ami instance with the sample application installed and working off the public dns. I&#39;m able to ssh into the
 instance but cannot find where tomcat 7 lives (ie. the conf directory to edit server.xml). I&#39;ve tried this with a 64 and 32 bit ami. Any ideas on where I might find this? I looked under:

    /etc
    /usr/share

I did find a `elasticbeanstalk-tomcat7-deployment` file under `tmp` (was empty).

I did a:

    sudo yum install tomcat7

and the sample application is also being served up from `:8080` and working on the public DNS. So I (think) have 2 tomcat servers running on the same beanstalk instance. In that case, I&#39;m trying to find where the Tomcat 7 folders are (serving pages on port `80`).

Where can I find the Tomcat 7 installation folder on Linux AMI in Elastic Beanstalk?

I want to view the unallocated free space on my hard disk through terminal.
I&#39;ve burned my brains searching the internet for a possible solution, but all in vain.

I used all sorts of commands like `df`, `du`, `fdisk`, `parted`, etc.
It tells me about the disks that are mounted and unmounted, but what about the unallocated space that I&#39;ve left free?

Of course I can view it using the &#39;Disk Utility&#39; app provided by Fedora, but since I LOVE being in the terminal I&#39;d like to view in it.

Can anyone please help me with a solution?

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?

I can&#39;t get my site to use gzip compression.

I recently watched this [video][1] by Chris Coyier over at css-tricks.com. In the video, he talks about enabling gzip compression to make websites run faster. 

As per his instruction, I linked through to github via html5boilerplate.com, copied the gzip compression code from their .htaccess file, pasted it into my own, and uploaded it to my site.

I&#39;ve tested it via gzipwtf.com and it doesn&#39;t seem to work. Can anyone help me with this?

I&#39;m trying to redirect https://www.example.com to http://www.example.com. I tried the following code in the .htaccess file

    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
    RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

This code successfully redirects https://example.com to http://www.example.com. However when I type in https://www.example.com then it gives me a &quot;web page not available&quot; error in the browser.

I have also tried the following 2 codes without success

Attempt 1

    RewriteEngine On
    RewriteCond %{HTTPS} !=on
    RewriteRule ^/(.*):NOSSL$ http://www.example.com/$1 [R=301,L]


Attempt 2

    RewriteEngine On
    RewriteCond %{HTTPS} on
    RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI}

Both above attempts failed. Any suggestions?

Am running MongoDB 2.2 on Ubuntu and if I run:

    sudo mongod

I get an error that it can&#39;t find /data/db, which is not where the database is. In mongod.conf the database path is specified as the Ubuntu 10gen default `/var/lib/mongodb` which is where the db is located. Seems like `mongod` is not finding the conf file. So when I run:

    sudo mongod -f /etc/mongodb.conf

The server starts up fine and output is logged to the log file: `/var/log/mongodb/mongodb.log`. All is happy. I can switch to another shell, log into mongo shell, see the databases and run queries.

So, I cancel out of that and try to run as a service:

    &gt; sudo status mongodb
    mongodb stop/waiting
    &gt; sudo start mongodb
    mongodb start/running, process 10468

Looks good so far, but the mongo server did not start. Running another:

    &gt; sudo status mongodb
    mongodb stop/waiting
    &gt; mongo
    MongoDB shell version: 2.2.0
    connecting to: test
    Sat Sep  1 19:07:43 Error: couldn&#39;t connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91
    exception: connect failed

&quot;test&quot; is not the correct database, and nothing appears in the log file.

I am at a loss as to what could be wrong. I checked the upstart scripts and they seem fine. `/etc/init/mongodb.conf` runs:

    mongodb --exec  /usr/bin/mongod -- --config /etc/mongodb.conf

MongoDB on Ubuntu won&#39;t start as a service, nothing in the log

I compiled and installed openCV 2.4.2 in ubuntu 12.04. Under `/usr/local/include` I can see the directories `/usr/local/opencv` and `/usr/local/opencv2`.

Here is the code I wrote:


    #include &lt;cv.h&gt;
    #include &lt;highgui.h&gt;
    #include &lt;iostream&gt;
    using namespace cv;
    using namespace std;
    int main(int argc,char **argv)
    {
       Mat image;
       image = imread(argv[1],1);

       if(argc != 2 || !image.data)
       {
           cout &lt;&lt; &quot;No image data\n&quot;;
           return -1;
       }

       namedWindow(&quot;Display Image&quot;,CV_WINDOW_AUTOSIZE);
       imshow(&quot;Display Image&quot;,image);
       waitKey(0);
       return 0;
    }

I compiled it using this command line:

    g++ DisplayImage.cpp -o DisplayImage `pkg-config opencv --cflags --libs` 

There were no compile time errors, however when I try to run the resulting binary with `/DisplayImage code.png` I get the following error message:

    ./DisplayImage: error while loading shared libraries: libopencv_core.so.2.4: cannot open shared object file: No such file or directory

By mistake I have removed /etc/nginx directory in my ubuntu 11.10 PC. How can I restore the ngnix directory in /etc/nginx ?

I did these commands:

 1. `sudo su`
 2. `rm -rf /etc/nginx`

I want to get again /etc/nginx directory. how?

I tried this to re-install nginx:

 1. `sudo apt-get update`
 2. `sudo apt-get upgrade`
 3. `sudo apt-get install nginx`
     
then it gives following

    Reading package lists... Done

    Reading state information... Done
    E: Unable to locate package nginx

I want a way to search in a given text. For that, I use `grep`:

    grep -i &quot;my_regex&quot;

That works. But given the data like this:

    This is the test data
    This is the error data as follows
    . . . 
    . . . .
    . . . . . . 
    . . . . . . . . .
    Error data ends

Once I found the word `error` (using `grep -i error data`), I wish to find the 10 lines that follow the word `error`. So my output should be:

    . . . 
    . . . .
    . . . . . . 
    . . . . . . . . .
    Error data ends

Are there any way to do it?

How do I fetch lines before/after the grep result in bash?

I&#39;m using a EC2 server instance. Used the following to install Jenkins:

    wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -
    sudo sh -c &#39;echo deb http://pkg.jenkins-ci.org/debian binary/ &gt; /etc/apt/sources.list.d/jenkins.list&#39;
    sudo apt-get update
    sudo apt-get install jenkins

but I need to install software on the Jenkins server so in my EC2 instance I did 

    sudo –s –H –u jenkins

to get into the jenkins server.
Then I tried to do

    sudo cabal install quickcheck
but it prompted me for jenkins password.
I&#39;ve been searching around the internet for 4hrs now and nothing is helping me get administrative privilege in the jenkins server.

What is the default Jenkins password?

I have a template that works and generates a stack but I cannot find a property to set or something else that allows me to give a Name to the EC2 Instance I have created. When it is generated the Name is blank.

Name an EC2 Instance in the CloudFormation template?

Trying to setup automatic redirection from http to https

    From manage.mydomain.com --- To ---&gt; https://manage.mydomain.com 

I have tried adding the following to my httpd.conf but it didn&#39;t work
        
     RewriteEngine on
        ReWriteCond %{SERVER_PORT} !^443$
        RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R,L]

Any ideas? 

How to automatically redirect HTTP to HTTPS on Apache servers?

All I wanted to do today was to write a redirect rule to a subfolder, e.g.:
You enter the URL: **example.com** and you get redirected to **example.com/subfolder**

Such a simple wish. I tried to find a solution on the internet. The internet told me to add an **.htaccess** file in the htdocs root with:

    RewriteEngine on
    RewriteCond %{HTTP_HOST} ^example\.com$
    RewriteRule (.*) http://www.example.com/$1 [R=301,L]
    RewriteRule ^$ subfolder [L]

I did this. But no success obviously, they didn&#39;t told me I had to uncomment the module in **httpd.conf**:

    LoadModule rewrite_module modules/mod_rewrite.so

So I did this too. No success again. They didn&#39;t told me I had to change my **httpd.conf** so that the **.htaccess** file would be enabled:

    &lt;Directory /&gt;
        Options FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
    &lt;/Directory&gt;
    
    DocumentRoot &quot;c:/Apache24/htdocs&quot;
    &lt;Directory &quot;c:/Apache24/htdocs&quot;&gt;
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    &lt;/Directory&gt;

Again no success, because I get this error when entering the URL:

&gt; Forbidden You don&#39;t have permission to access / on this server.

Now I&#39;m stuck and I couldn&#39;t find any more solutions on the internet. I&#39;m just running Apache 2.4 on my Windows 7 machine, for private reasons.

Forbidden You don&#39;t have permission to access / on this server

I am trying to proxy a subdirectory to another server. My httpd.conf:

    RewriteEngine On
    ProxyPreserveHost On
    RewriteRule .*subdir/ https://anotherserver/subdir/ [P]

The problem is that Apache is always logging this:

    AH01144: No protocol handler was valid for the URL /subdir/. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule., referer: http://localhost/

So after searching the internet, I have activated these modules:

    LoadModule headers_module modules/mod_headers.so
    LoadModule proxy_module modules/mod_proxy.so
    LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
    LoadModule proxy_connect_module modules/mod_proxy_connect.so
    LoadModule proxy_express_module modules/mod_proxy_express.so
    LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
    LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
    LoadModule proxy_html_module modules/mod_proxy_html.so
    LoadModule proxy_http_module modules/mod_proxy_http.so
    LoadModule proxy_scgi_module modules/mod_proxy_scgi.so
    LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so
    LoadModule rewrite_module modules/mod_rewrite.so

(I know that I don&#39;t need all of them but I just activated them to be sure I am not missing one)

But this error still appears and clients get a HTTP 500.

How can I fix this?

Apache Proxy: No protocol handler was valid

I configured apache server as a reverse proxy and it works fine if I point a backend server as HTTP. That is:

I configured virtual host 443 like:

    ProxyPass /primary/store http://localhost:9763/store/
    ProxyPassReverse /primary/store http://localhost:9763/store/

Here users will access the server like `https://localhost/primary/store`

And this works fine... But I want to configure HTTP server like;

    ProxyPass /primary/store https://localhost:9443/store/
    ProxyPassReverse /primary/store https://localhost:9443/store/

When I configure like apache server gives 500 internal server error. What am I doing wrong here?

The error I get is:

    The server encountered an internal error or misconfiguration and was unable to complete your request.
    
    Please contact the server administrator, you@example.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
    
    More information about this error may be available in the server error log.

In the apache error log it states;
