CentOS 6.2 64bit Installation Steps:
1. download the libssh2 package from http://libssh2.org, command as following:
tar vxzf libssh2-1.4.2.tar.gz
cd libssh2-1.4.2
./configure
make
make install
2. download the php-ssh2 package from http://pecl.php.net/package/ssh2:
tar vxzf ssh2-0.11.3
cd ssh2-0.11.3
phpize
./configure --with-ssh2
make
make install
and the ssh2.so file will copy into /usr/lib64/php/modules
check it.
3. modify the php.ini
vi /etc/php.ini
add the "extension=ssh2.so" to the extension part of php.ini
4. check the environment of php, use phpinfo();

> sudo /etc/init.d/apache2 restart

Using PECL it must be specified the channel, since the beta version has to be choosen instead of stable one:
$ pecl install ssh2 channel://pecl.php.net/ssh2-version

To help someone avoid the headaches I did for a week. SSH2 functions have problems with the ssh2-beta & libssh2-0.18 even after patching with said patches on the internet.
ssh_exec will work fine
ssh2_shell will not work
In order to use ssh2_shell I had to roll back to libssh2-0.14 in order to get ssh2_shell function to work properly

Just a little note: when compiling this package after modifying the ssh2.c, do not use pecl build as it will not create an ssh2.so file (although it says it succeeded), use:
phpize
./configure --with-ssh2
make
you then need to copy the ssh2.so file into your extension dir if it didn't do so already.

LIBSSH2_APINO was removed from the public header file. You need to patch ssh2.c to work with new libssh2 versions.
ssh2.c patch:
LINE 480:
search and change following line:
#if LIBSSH2_APINO < 200412301450
...
#else
to:
#if (defined(LIBSSH2_APINO) && LIBSSH2_APINO < 200412301450)
...
#else /* if LIBSSH2_APINO is not defined its v0.14 or higher. no problem! */
LINE 1216:
search and change following line:
#if (LIBSSH2_APINO > 200503221619)
to:
#if (defined(LIBSSH2_APINO) && (LIBSSH2_APINO > 200503221619)) || (defined(LIBSSH2_VERSION_NUM) && LIBSSH2_VERSION_NUM >= 0x001000)
Compile again!
