Installing libssh2 via tar.gz from <a href="http://sourceforge.net/projects/libssh2/" rel="nofollow noreferrer">http://sourceforge.net/projects/libssh2/</a> help a lot (--with-ssh2=/usr/local/include/).
But :

<code>yum install libssh2-devel</code> didn't work for me:

So I downloaded rpm package from <a href="https://www.rpmfind.net/linux/rpm2html/search.php?query=libssh2-devel" rel="nofollow">rpmfind</a> and installed with <code>rpm -ivh</code>

Regarding line:

Make sure that path <code>/etc/php/7.2/mods-available</code> is valid and there is a match with your php version.

I'm running on Centos, none of these answer were the entire solution for me. I followed <a href="http://blog.dynamichosting.biz/2011/01/10/installing-ssh2-extension-for-php-on-centos-5/" rel="nofollow">these instructions</a>:

<pre><code>$ sudo yum install -y gcc php-devel php-pear libssh2 libssh2-devel
</code></pre>

But <code>php-devel</code> would not install, complaining about conflicts. I searched yum to find what php devel packages I had available

<pre><code>$&gt; yum search php|grep devel
...
php55u-devel.x86_64 : Files needed for building PHP extensions
php56u-devel.x86_64 : Files needed for building PHP extensions
php70u-devel.x86_64 : Files needed for building PHP extensions
...
</code></pre>

So I ran

<pre><code>$&gt; sudo yum install -y php56u-devel
</code></pre>

And it installed cleanly. Then, continuing with the instructions, I ran

<pre><code>$ pecl install -f ssh2
</code></pre>

And it compiled. Then I added the extension to php

<pre><code>$ touch /etc/php.d/ssh2.ini
$ echo extension=ssh2.so &gt; /etc/php.d/ssh2.ini
</code></pre>

And on my system, instead of 

<pre><code>$ /etc/init.d/httpd restart
</code></pre>

I had to do

<pre><code>$ sudo /bin/systemctl restart php-fpm.service 
</code></pre>

So that was all the steps to install. And finally to confirm:

<pre><code>$&gt; php -m|grep ssh2
ssh2
</code></pre>

I had this problem:

I'm on a Pair.com "Advanced" hosted account, so I'm a little limited on what I'm allowed to do. I don't think I can <code>yum</code> nor <code>aptitude</code> nor any of the other pre-compiled packages.

I've downloaded and compiled libssh2. During the <code>pecl</code> process, it asks where the library is located. It's in "~/usr/local/lib" and I've tried several variations, including fully qualified. But I kept getting the same error.

The error message doesn't spell out precisely which file it's looking for. libssh2.so is in that directory. I know the output is supposed to be ssh2.so. I wondered if there is supposed to be an ss2.something, or libssh.nothing?

I fixed it thus. In my case, after compiling libssh2 I downloaded the PEAR tarball. The trick was:

<pre><code>./configure --with-ssh2=&lt;libssh2 location&gt; --prefix=&lt;libssh2 location&gt;
</code></pre>

Another trick is that, since Pair.com is running FreeBSD, I have to do a "cd ." after the ./configure command. Otherwise, make produces a "Permission denied" error. Apparently, this is necessary on all *nix BSD flavors.

The error:
<pre><code>checking for ssh2 files in default path... not found
configure: error: The required libssh2 library was not found.
</code></pre>
...can be seen in <a href="http://git.php.net/?p=pecl/networking/ssh2.git;a=blob;f=config.m4;h=c6b5354b1f4ac542a3068d418a58d77de5e22b33;hb=HEAD#l23" rel="nofollow noreferrer">the source code</a>.
The logic in the code reveals that it will throw this error if it cannot find <code>/include/libssh2.h</code> in either <code>/usr/local</code>, <code>/usr</code> or in the path supplied by the optional <code>--with-ssh2=[DIR]</code> directive. In other words, without customising the directive, it needs to find one of the following:
<pre><code>/usr/local/include/libssh2.h
/usr/include/libssh2.h
</code></pre>
If it passes this check, it then assumes it can find the libssh2 <code>lib</code> at <code>/usr/local/lib</code> or <code>/usr/lib</code>.
Hopefully the info above is enough to help someone debug their issue. My own case is fairly specific and unusual (macOS with Homebrew in a custom install path), but in case it helps anyone else, here's my horrifically hacky workaround. Works perfectly lol
In a nutshell I'm creating two temporary symlinks so that pecl can find ssh2 where it expects.
<pre class="lang-sh prettyprint-override"><code># First check that neither /usr/local/include nor /usr/local/lib exists

sudo ln -s /usr/local/CustomInstallPath/Homebrew/Cellar/libssh2/1.9.0_1/include /usr/local/include
sudo ln -s /usr/local/CustomInstallPath/Homebrew/Cellar/libssh2/1.9.0_1/lib /usr/local/lib
pecl install -a ssh2-1.3.1
sudo rm -rf /usr/local/include
sudo rm -rf /usr/local/lib
</code></pre>

I am trying to install this
<a href="http://fr2.php.net/manual/en/book.ssh2.php" rel="nofollow noreferrer">http://fr2.php.net/manual/en/book.ssh2.php</a>
on a Centos 5 (a fork of RHEL 5).
I installed libssh2 (yum install libssh2) which is located in /usr/lib, and when I install SSH2 extension (via pecl install -f ssh2) I get this message
<blockquote>
