Wow, almost a year I didn’t touch this blog. At least this blog still have visitor from nowhere 🙂

Ok, today I have challenge to install phalcon php extension (at the moment the version is 3.4.2). The vps server already has centminmod installed using latest version of CentOS 7.

Since the server is critical so I decide to use other vps server (get free $25 in credit for new user here) to get the recipe and share it here for others that might need it.

Lets get start!

Update CentOS

# yum update

Check current php version

# php -v

PHP 7.0.33 (cli) (built: Feb 16 2019 10:38:06) ( NTS )

Yes, this legacy app run on php 7.0.33

Compile Phalcon php

# git clone --branch v3.4.2 --depth=1 "git://github.com/phalcon/cphalcon.git"

# cd cphalcon/build/

# ./install

———————————————————————-
Libraries have been installed in:
/root/cphalcon/build/php7/64bits/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR’
flag during linking and do at least one of the following:
– add LIBDIR to the `LD_LIBRARY_PATH’ environment variable
during execution
– add LIBDIR to the `LD_RUN_PATH’ environment variable
during linking
– use the `-Wl,–rpath -Wl,LIBDIR’ linker flag
– have your system administrator add LIBDIR to `/etc/ld.so.conf’

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don’t forget to run ‘make test’.

Installing shared extensions: /usr/local/lib/php/extensions/no-debug-non-zts-20151012/
Installing header files: /usr/local/include/php/

Thanks for compiling Phalcon!
Build succeed: Please restart your web server to complete the installation

Enable phalcon extension

# nano /etc/centminmod/php.d/phalcon.ini

fill with this line :

extension=phalcon.so

save the file and restart

# nprestart

Check if phalcon extension installed

echo ‘<?php phpinfo();?>’ > /usr/local/nginx/html/info2.php

then access it with browser

or using command line

# php -m | grep phalcon

Handling rewrite problem

“Mod-Rewrite is not enabled

Please enable rewrite module on your web server to continue”

# nano /usr/local/nginx/conf/conf.d/learn.digitalfusi.com.ssl.conf

Change these sections :

1. root /home/nginx/domains/url/public/public;
2. try_files $uri $uri/ /index.php?_url=$uri&$args;

save.

Update 1 :

section 2 need to update as this :

try_files $uri $uri/ @rewrite;

and make new section for @rewrite :

location @rewrite {
rewrite ^/(.*)$ /index.php?_url=/$1;
} #rewrite

Update 2 :

Handling error message :

“warning: Remote branch v3.4.3 not found in upstream origin, using HEAD instead”

wget -c https://github.com/phalcon/cphalcon/archive/v3.4.3.tar.gz

tar xvzf v3.4.3.tar.gz

cd cphalcon-3.4.3/build/

./install

Try if rewrite rule work

Edit controller file

# nano /home/nginx/domains/url/public/app/controllers/IndexController.php

Modify the content to this

<?php

class IndexController extends ControllerBase
{

public function indexAction()
{

}

public function testAction($id1,$id2,$id3)

{
echo ‘really nice bro ‘.$id1.’ var 2 :’.$id2.’ var 3 : ‘.$id3;
}
}

save the file.

Access the address from browser

https://url/index/test/d/e/f

and the output will be

really nice bro d var 2 :e var 3 : f

Great, since the value of d,e and f printed correctly then rewrite rule work perfectly.

Note :

• I upload sample project inside public folder so for root (document root) I change it to public/public.
• url in this note is depend on you. It might be tld os subdomain
• I enable https by default so I only deal with ssl.conf file
• webtools only available from localhost, enable it from cmd -> phalcon project projectname –enable-webtools

Update : The offer seem no longer available.

I have to prepare for new class that required vps access. The class will teach unix based system like openbsd, freebsd, dragonfly bsd plus netbsd in 12 meets.

This class will be basic for devops but most important thing for me is my student can get full environment in every OS. Vps came to my mind and this March 2017 is really great since Vultr announce great news :

They double everything and they also provide ‘sanbox plan’ for beginner.

In nutshell you’ll get 1GB memory and 25Gb space vps on the OS you choose. SSD speed also superb :

dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 3.87756 s, 277 MB/s

For limited time Vultr offer free $20 that you can use for many things;

• Set git server using gitlab.
• Set up aws compatible cloud with minio
• Testing zfs latest FreeBSD 12 vs Hammer in dragonflybsd
• Tes mysql replicate while setting master in Germany Vps and mysql slave in Paris or Amsterdam.

Long time ago I’ll need $10 server to achieve that but now I just need $5 vps server /mo to get 1GB server which is awesome 🙂

I just spread the news to let others know and grab your free $20 by using this link.

Long live the queen!
