How to Install, Configure & Run HHVM in Amazon Linux server with Apache?
HHVM is an open-source virtual machine designed for executing programs written in Hack and PHP. HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining the development flexibility that PHP provides.
We will get a lot of information about what is HHVM from the web. The most difficult part of it is to get a step by step process of how to install HHVM. For supported platforms, HHVM official website itself provides some installation steps but for unsupported HHVM platforms installation of packages and compilation steps are less available.
Here we are providing step by step process to install, configure and run HHVM in an unsupported platform Amazone Linux server with Apache
1: Install Apache and httpd-devel
1: Install Apache (how to install Apache is not included in this doc. Please refer appropriate docs for that )
2: Check whether you have the required build files for handling the HHVM. Check whether you have a build directory in Apache and that directory has some required files like system.mk
a: Find your installed Apache root :
apachectl -V
The above comment will output as follows
Server version: Apache/2.2.31 (Unix) Server built: Aug 13 2015 23:45:37 Server's Module Magic Number: 20051115:40 Server loaded: APR 1.5.0, APR-Util 1.4.1 Compiled using: APR 1.5.0, APR-Util 1.4.1 Architecture: 64-bit Server MPM: Prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APACHE_MPM_DIR="server/mpm/prefork" -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=128 -D HTTPD_ROOT="/etc/httpd" -D SUEXEC_BIN="/usr/sbin/suexec" -D DEFAULT_PIDLOG="run/httpd.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_LOCKFILE="logs/accept.lock" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="conf/mime.types" -D SERVER_CONFIG_FILE="conf/httpd.conf"
Here, check the HTTPD_ROOT , if it says etc/httpd , check whether you have a build directory inside this etc/httpd . Some times this HTTPD_ROOT is /etc/apache2 , depends on the server we have installed. If etc/httpd then for all later installations we are going to use the httpd folder . If it is etc/apache2 , then, for all the installations that comes later, we will use the apache2 folder.
Check for build directory . Here in this document , we are using the httpd based on the above output . If you have got apache2 , then use apache2 instead of httpd.
Find all the httpd folder
whereis httpd
You may get the an output similar to
httpd: /usr/sbin/httpd.worker /usr/sbin/httpd.event /usr/sbin/httpd /usr/lib64/httpd /etc/httpd /usr/include/httpd /usr/share/man/man8/httpd.8.gz
These are the httpd folders . Use cd comments to walk through this folders and check if we have build directory. One example I can give as follows
cd /usr/lib64/httpd
use ls comment to see the files/folders in this .
ls
Similarly, use ls with respect to the httpd folders to find the build folder.If you didn’t find a build folder , we need to install that . For that use
sudo yum install -y httpd-devel
After that check, we have updated the httpd and we got the build directory. Recheck using whereis httpd and cd to each httpd and ls on it. I got the build directory in cd /usr/lib64/httpd . Also confirm that you have the following files inside that build directory. Use ls comment to see the files inside build directory.
config_vars.mk library.mk mkdir.sh rules.mk instdso.sh ltlib.mk program.mk special.mk
2: Install mod_proxy_fcgi
Apache 2.4 shipped mod_proxy_fcgi as part of the core distribution. This git repository provides a modified version backported to work with Apache 2.2 in order to work on older distributions (eg. Red Hat Enterprise Linux 6).
To get the source, compile, and install: Do the following one by one
sudo git clone https://github.com/ceph/mod-proxy-fcgi cd mod-proxy-fcgi sudo autoconf sudo ./configure sudo make sudo make install
After this make sure that mod_proxy_fcgi is installed . To do that , check for a modules folder inside the httpd folder. Search similar to what we have done for finding the build folder earlier . I found my modules folder of httpd inside /etc/httpd
cd /etc/httpd ls
If the installation goes ok , you can see mod_proxy_fcgi.so inside that folder
Now we need to load this module inside our httpd config file. This is the main configuration file of Apache . Locate your httpd config file. I found my httpd.conf file inside /etc/httpd/conf/httpd.conf . Open that file
sudo vim /etc/httpd/conf/httpd.conf
Go through that file and find the place where a list of LoadMoudules are written.
Check for the line , LoadModule proxy_module modules/mod_proxy.so . If you dont find such one , please add the same . Then add our new installed mod_proxy_fastcgi as follows.
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
save that file (press escape , then :wq will save the file ).
Now restart your Apache as follows .
sudo service httpd restart
You will get the output as
[[email protected] /]$ sudo service httpd restart Stopping httpd: [ OK ] Starting httpd: [ OK ]
3: Install mod_fastcgi
Download the module and install . Lets download to /usr/local/src.
Before downloading , remember where your httpd/apache2 build directory is
in my case , /usr/lib64/httpd
Do the following steps one by one:
cd /usr/local/src sudo wget http://www.fastcgi.com/dist/mod_fastcgi-current.tar.gz sudo tar -xzvf mod_fastcgi-current.tar.gz sudo cp Makefile.AP2 Makefile sudo make top_dir=/usr/lib64/httpd sudo make top_dir=/usr/lib64/httpd install
keep in mind that top_dir = the build directory
If the installation goes fine, you can see mod_fastcgi. Inside the modules folder of httpd . Check similar to what we have done for mod_proxy_fcgi.so.
Then load this new installed mod_fastcgi inside the httpd conf file . Add the following to that file just below the previous LoadModule that we have added for mod_proxy_fastcgi
LoadModule fastcgi_module modules/mod_fastcgi.so
Now restart your Apache as follows .
sudo service httpd restart
You will get the output as
[[email protected] /]$ sudo service httpd restart Stopping httpd: [ OK ] Starting httpd: [ OK ]
4: Install HHVM Dependencies
First update all package and install all the dependencies. Do the following one at a time. A step by step approach is better because its easy to trace any error that you may come across during installation. Some of the installations may be already installed.
sudo yum -y update sudo yum -y install autoconf sudo yum -y install automake sudo yum -y install binutils-devel sudo yum -y install boost-devel sudo yum -y install bzip2-devel sudo yum -y install chrpath sudo yum -y install cmake sudo yum -y install cpp sudo yum -y install curl-devel sudo yum -y install elfutils-libelf-devel sudo yum -y install expat-devel sudo yum -y install gcc-c++ sudo yum -y install gd-devel sudo yum -y install git sudo yum -y install jemalloc-devel sudo yum -y install libIDL-devel sudo yum -y install libc-client-devel sudo yum -y install libcap-devel sudo yum -y install libevent-devel sudo yum -y install libicu-devel sudo yum -y install libmcrypt-devel sudo yum -y install libmemcached-devel sudo yum -y install libtool sudo yum -y install libxml2-devel sudo yum -y install make sudo yum -y install memcached sudo yum -y install mysql-devel sudo yum -y install oniguruma-devel sudo yum -y install openldap-devel sudo yum -y install pam-devel sudo yum -y install patch sudo yum -y install pcre-devel sudo yum -y install readline-devel sudo yum -y install svn sudo yum -y install wget sudo yum -y install libxslt-devel sudo yum -y install ImageMagick-devel
5: Checkout HHVM and Submodules
Lets checkout in /usr/local/src ( Not compulsory to check it out here)
Do the following
cd /usr/local/src sudo git clone git://github.com/facebook/hhvm.git cd hhvm sudo git checkout HHVM-3.3 sudo git submodule update --init –recursive export CMAKE_PREFIX_PATH=`pwd`/.. cd /
Now we just check the source, we can come back to installation later. Before that we need some more dependenciies for the HHVM . Lets install that .
6: Install Intel Thread Building Blocks (tbb) (4.0 or newer)
Lets install in the same /usr/local/src
cd /usr/local/src sudo wget https://www.threadingbuildingblocks.org/sites/default/files/software_releases/source/tbb42_20130725oss_src.tgz sudo tar zxvf tbb42*.tgz cd tbb42* cd src sudo make cd .. sudo mkdir -p /usr/include/serial sudo cp -a include/serial/* /usr/include/serial/ sudo mkdir -p /usr/include/tbb sudo cp -a include/tbb/* /usr/include/tbb/ sudo cp build/linux_intel64*/libtbb.so.2 /usr/lib64/ sudo ln -s /usr/lib64/libtbb.so.2 /usr/lib64/libtbb.so cd ..
7: Install libDwarf
Lets install in the same /usr/local/src
sudo git clone git://git.code.sf.net/p/libdwarf/code libdwarf cd libdwarf/libdwarf sudo git checkout 2346f43f57f0ae768adffa55ea84b281d3aa71da sudo ./configure sudo make sudo cp libdwarf.a /usr/lib64/ sudo cp libdwarf.h /usr/include/ sudo cp dwarf.h /usr/include/ cd ../..
8: Install Google glog
Lets install in the same /usr/local/src
sudo wget https://google-glog.googlecode.com/files/glog-0.3.3.tar.gz sudo tar zxvf glog-0.3.3.tar.gz sudo svn checkout http://google-glog.googlecode.com/svn/trunk/ google-glog cd google-glog sudo ./configure –prefix=/usr sudo make sudo make install cd ..
9: Refreshing library cache.
First Refreshing library cache. Just run the following commend
sudo ldconfig
10: Building HHVM
Make sure we are in /usr/local/src where we checkout the HHVM ealier
then do the following
cd hhvm sudo cmake . sudo make (this is a lengthy process may consume 1 -2hour :( ) sudo make install
Now your HHVM installation is complete. Since it is from the source , we need to create some files manually . Lets do that now
10-1: Create a file at /etc/init.d/hhvm
Before that remember where we installed the HHVM , to find that use
whereis hhvm
we may get an output as
hhvm: /usr/local/bin/hhvm
Remember this path , we need this in next step
Now Create a HHVM file in /etc/init.d/h
cd /etc/init.d sudo vim hhvm
then paste the following code in that
#! /bin/sh
test -x /usr/local/bin/HHVM || exit 0
case "$1" in
start)
/usr/local/bin/HHVM --config /etc/hhvm/server.hdf --user www-data --mode daemon
;;
stop)
start-stop-daemon --stop --quiet --oknodo --pidfile /var/run/hhvm/pid
;;
reload|force-reload|restart|try-restart)
$0 stop
$0 start
;;
status)
echo "No status"
;;
*)
echo "Usage: /etc/init.d/HHVM {start|stop|restart|status}"
exit 1
esac
exit 0
Please note that in the above code I have used /usr/local/bin/HHVM in two places. Dont forget to give your HHVM installed path here. I.E. the path we just checked earlier using where is HHVM command.
Save the file.
Also the above code have two another files mentioned /etc/hhvm/server.hdf and /var/run/hhvm/pid
We are next coming to that files.
10-2: Create a file /etc/hhvm/server.hdf
Now, we need to create the /etc/hhvm/server.hdf file.
sudo mkdir hhvm sudo vim /etc/hhvm/server.hdf
Paste the following code in it and save.
PidFile = /var/run/hhvm/pid
Server {
SourceRoot = /var/www/html
DefaultDocument = index.php
Type=fastcgi
Port=9000
PathDebug =false
}
VirtualHost {
* {
Pattern = ^(.*)
ServerVariables {
PHP_SELF = /index.php
SCRIPT_NAME = /index.php
}
RewriteRules {
* {
pattern = ^(.*)
to = ^(.*) index.php?do=/$1
qsa = true
}
}
}
}
#include "/usr/share/hhvm/hdf/static.mime-types.hdf"
StaticFile {
FilesMatch {
* {
pattern = .*\.(dll|exe)
headers {
* = Content-Disposition: attachment
}
}
}
Extensions : StaticMimeTypes
}
ErrorHandling {
CallUserHandlerOnFatals = true
NoInfiniteRecursionDetection = false
ThrowBadTypeExceptions = false
ThrowTooManyArguments = false
WarnTooManyArguments = false
ThrowMissingArguments = false
ThrowInvalidArguments = false
EnableHipHopErrors = true
NoticeFrequency = 1 # 1 out of these many notices to log
WarningFrequency = 1 # 1 out of these many warnings to log
AssertActive = false
AssertWarning = false
}
Repo {
Central {
Path = /var/log/hhvm/.hhvm.hhbc
}
}
Log {
Level = Error
AlwaysLogUnhandledExceptions = true
RuntimeErrorReportingLevel = 8191
UseLogFile = true
UseSyslog = false
File = /var/log/hhvm/error.log
Access {
* {
File = /var/log/hhvm/access.log
Format = %h %l %u % t \"%r\" %>s %b
}
}
}
MySQL {
TypedResults = false
}
In the above file make sure SourceRoot = your Apache webservice root .In my case it is SourceRoot = /var/www/html . I am going to place all my application/project/php files inside this .
Now Just save this file. We need to comeback to this file for our HHVM configuration with PHP. Please note that this file is including a new file
/usr/share/hhvm/hdf/static.mime-types.hdf . We dont have such a file now , so we need to create that . Before that just save this edited file.
10-3: Create a /usr/share/hhvm/hdf/static.mime-types.hdf
Now create /usr/share/hhvm/hdf/static.mime-types.hdf
cd /usr/share sudo mkdir hhvm cd hhvm sudo mkdir hdf cd hdf sudo vim static.mime-types.hdf
Now place , the following code in that and save

}
save this file.
Now we need to create two more folders
/var/run/HHVM
/var/log/HHVM
10-4: Create two directories /var/log/HHVM and /var/run/hhvm
sudo mkdir /var/log/hhvm sudo mkdir /var/run/hhvm
Now we created almost all the required files for HHVM.
10-5: HHVM to Listen to a Port 9000
Now the important thing , ask HHVM to listen to a port . We are using the port 9000. make sure port 9000 is available in AWS.
We are make use of our previous installed fastcgi module for this
/usr/local/bin/HHVM --mode server -vServer.Port=9000 -vServer.Type=fastcgi &
when you run this you may get an output as follows
[[email protected] /]$ /usr/local/bin/HHVM --mode server -vServer.Port=9000 -vServer.Type=fastcgi & [1] 10560 [[email protected] /]$ mapping self... mapping self took 0'00" (7269 us) wall time loading static content... loading static content took 0'00" (1 us) wall time page server started all servers started Unable to open pid file www.pid for write
Dont mind the last error above. Just leave it . But make sure that after this HHVM is listening to the port. To check that use the following.
ps aux | grep hhvm
You may get an output as follows:
[[email protected] /]$ ps aux | grep hhvm ec2-user 10560 3.8 1.5 633792 58348 pts/0 Sl 04:51 0:01 /usr/local/bin/HHVM --mode server -vServer.Port=9000 -vServer.Type=fastcgi ec2-user 10565 0.0 0.0 110448 888 pts/0 S+ 04:52 0:00 grep --color=auto hhvm
Also try
sudo fuser -v 9000/tcp
this will output as
[[email protected] /]$ sudo fuser -v 9000/tcp USER PID ACCESS COMMAND 9000/tcp: root 10619 F.... hhvm
This shows that our installed HHVM is start listening to the port 9000. Good !
10-6: Run HHVM
Now we need to run HHVM . For that we need to change the permission of /etc/init.d/HHVM file to a super permission. Use the following commend
sudo chmod +x /etc/init.d/hhvm
Now we can run HHVM using HHVM service.
use
sudo /etc/init.d/HHVM restart
or use
sudo service HHVM start
You may get output as
[[email protected] /]$ sudo /etc/init.d/HHVM restart /etc/init.d/hhvm: line 10: start-stop-daemon: command not found Possible bad config node: ErrorHandling.ThrowBadTypeExceptions Possible bad config node: ErrorHandling.ThrowTooManyArguments Possible bad config node: ErrorHandling.ThrowMissingArguments Possible bad config node: ErrorHandling.ThrowInvalidArguments
[[email protected] /]$ sudo service HHVM start Possible bad config node: ErrorHandling.ThrowBadTypeExceptions Possible bad config node: ErrorHandling.ThrowTooManyArguments Possible bad config node: ErrorHandling.ThrowMissingArguments Possible bad config node: ErrorHandling.ThrowInvalidArguments
Please don’t mind about the errors its outputting. This will not cause any harm to your installation or configuration. We can confirm whether HHVM is working or not via a PHP file.
10-7: Test HHVM
For that create a checkhhvm.php file inside your project root folder. In my case it is var/www/html. So I am creating a checkhhvm.php file inside that.
sudo vim /var/www/html/checkhhvm.php
Add the following to this file
<?php
if (defined('HHVM_VERSION')) {
echo 'HHVM is working';
phpinfo();
}
else {
echo 'HHVM is not working';
}
?>
The run this file via HHVM as follows
hhvm/var/www/html/checkhhvm.php
if you get an output like this . We are done !!!!
[[email protected] /]$ HHVM /var/www/html/checkhhvm.php
HHVM is workingHipHop
10-8: Enable HHVM to talk with Apache (setup a virtual host)
Now check what is the output of this file when you access via browser ?
For that just load this page via any browser If your in a local machine , then localhost/checkhhvm.php or 127.0.0.1/checkhhvm.php will help or if you are in a server use the server ip or domain.
When you view the output the most disappointing thing is it says
HHVM is not working
Don’t Worry 🙂 . We have the solution . This is because our Apache is still running on PHP and we have not requested HHVM to take that place. We need to ask HHVM to look all our PHP files . For that we need to create a virtual host in our Apache config file .
So open the httpd.conf file
sudo vim /etc/httpd/conf/httpd.conf (this is my conf file path..pls use your's)
then on that file look for something like this
#<VirtualHost *:80> # ServerAdmin [email protected] # DocumentRoot /www/docs/dummy-host.example.com # ServerName dummy-host.example.com # ErrorLog logs/dummy-host.example.com-error_log # CustomLog logs/dummy-host.example.com-access_log common #</VirtualHost>
below that add our virtual host as follows
<VirtualHost *:80> DirectorySlash On DirectoryIndex index.php DocumentRoot /var/www/html/ ProxyRequests On ProxyPreserveHost On ProxyVia full # ProxyPass / fcgi://127.0.0.1:9000/var/www/html/ ProxyPassMatch ^/(.+\.(hh|php)(/.*)?)$ fcgi://127.0.0.1:9000/var/www/html/$1 ErrorLog /var/log/httpd/hiphop.error.log </VirtualHost>
Now just reload your page . It will say Hiphop is running !
This line in the virtual host is requesting the HHVM to take care of all the PHP files in our root folder with the help of fastcgi module
ProxyPassMatch ^/(.+\.(hh|php)(/.*)?)$ fcgi://127.0.0.1:9000/var/www/html/$1
make sure the following 9000 is the HHVM port and /var/www/html/ is my root folder.
So successfully run the HHVM on our checkhhvm.php file . Now how to run our full application via this HHVM ? Lets see that .
10-9: Run our full application via this HHVM
For an application , we may have different types of URL formats.
For example,
www.domain.com/index.php
http://example.com/index.php?q=about
http://example.com/index.php?do=about
www.domain.com/mypage
These URLs are handled in the server.hdf file of HHVM.
Lets examine that open the file
sudo vim /etc/hhvm/server.hdf.
In that we can find
Server {
SourceRoot = /var/www/html
DefaultDocument = index.php
Type=fastcgi
Port=9000
PathDebug =false
}
SourceRoot is the root of your webappilcation. In my case it is var/www/html
DefaultDocument = index.php , the first file to load .
Type=fastcgi , HHVM seking the help of fastcgi module to talk with apache
Port=9000 , the port in which the HHVM is listening
Now lets examine the next major part of the file
VirtualHost {
*{
Pattern = ^(.*)
ServerVariables {
PHP_SELF = /index.php
SCRIPT_NAME = /index.php
}
RewriteRules
{
*{
pattern = ^(.*)
to = ^(.*) index.php?do=/$1
qsa = true
}
}
}
pattern = ^(.*) , this is a pregmatch for files to load , this pattern will load all types
to = ^(.*) index.php?do=/$1 , this is an important one. It determines which all the URL format
of our application are to be handled by HHVM. Here in the example it says index.php?do
type URLs are to be handled. You can find the rewrite URL of your application from the
htaccess file of your application. Just check for RewriteRules in your htaccess and copy
the same to here.
That’s all … From now you can experience the power of HHVM.
