Setup Nginx php FPM apc Maria. DB on Debian 7 The perfect LEMP server. Debian webserver. Debian is a great choice for setting up linux webservers. According to current stats it is the most popular server OS followed closely by centos. I am a great fan of the aptdpkggdebi commands, which make it so easy to install and update packages on the system. To setup a complete functional php webserver, you need to install a couple of extra things which include a webserver and a database. In this post we shall be setting up nginx, php, php fpm, apc and Maria. DB. Nginx is a modern webserver, that has been designed to handle large amounts of traffic using the least amount of resources in terms of RAM and CPU.

However as the internet became more populated, the need for a faster and efficient webserver grew. Nginx vs Apache. Apache by design is very bulky and has tons of features, most of which are not necessary for typical websites. It was probably designed to satisfy everyones needs, but this ended up making it a large and heavy webserver with mostly unused features. Nginx on the other hand is a very sleek and swift webserver that focuses entirely on speed, scalability, and efficiency. The technicals of how it does so are large and beyond the scope of this post.

Just for your information this website runs on nginx. Now without any further discussion lets get to work. Install Nginx on Debian. The nginx package is right there in the debian repositories so you dont have to look anywhere else. Fire up apt get and install it. Now launch the nginx server. Starting nginx nginx.

If you have not heard about letsencrypt it is an amazing, and free, certificate authority. It proves free as in beer ssl certificates for anyone who can prove they. Now access the nginx server from browser by opening the urlhttp localhostand you should get the welcome message. Welcome to nginx Important notes. There are few things you should memorise to manage your nginx server better. The nginx configuration files are found in the following locationetcnginxemail protected etcnginx ls. We shall not modify the nginx. Instead we create a separate configuration file for each vhostsite and save it in the following directories. This is similar to apache. The sites enabled directory contains the configurations for vhosts that are to be enabled. It contains symlinks to the corresponding configuration files in sites available directory. Setup a virtualhost. Now that we have installed nginx, its time to setup a virtual host. This is what you would be doing on a real webserver to setup your site. Inside etcnginxsites available you would see a file named default. It is a template file to create your own configuration files. Just copy it and name it to your site. We choose to name the configuration files with the site name, so that it is easier to remember and maintain. Now open up binarytides. You would see a server block similar to thisserver. Make site accessible from http localhost. This first thing to configure here is the servername. Name it to your site. For exampleservername binarytides. When someone opens binarytides. When a matching server block is found, it would use the configuration from that particular server block. Another thing to configure is the web root directory for this sitevhost. Note that this is by default usrsharenginxwww which you might want to change to something else. The general convention is to have a separate directory for each vhost. For exampleusrsharenginxwwwbinarytides. So create an appropriate directory and point the root setting in the configuration file to the directory After doing these changes, save the configuration file and create a symlink the etcnginxsites enabled directory. Now test your new configuration nginx t. The last line of the output must say successful, or some error would be shown. It might show some warnings which can be fixed later. Finally restart nginx for the new configuration to take effect service nginx restart. Restarting nginx nginx warn conflicting server name localhost on 0. So the new configuration has taken effect. Now create a new index. Install php and php fpm. The next thing to install is the php interpreter and php fpm. Php FPM is dedicated fastcgi process manager for php that can interface or connect with any compatible webserver and manage php processes to process php requests. Nginx lt communicates Php FPM lt manages php child process. Install the necessary packages first. It will automatically install the necessary dependencies. You can install php. Php fpm runs as a separate server and nginx communicates with it over a socket. Hence the php execution is totally outside the server. Also since fpm keeps php process persistent, it fully supports APC. Now locate the php fpm configuration files. The files at located atetcphp. A pool is a bunch of php processes running with same usergroup. So if you want the php files of each site to run with a separate user permission, then you need to create separate pools of fpm. For simplicity sake we just showing a single pool here. The pool configuration files are inside the pool. Navigate inemail protected etcphp. Open the www. conf file which is again a template for you to use and create separate configuration files for each pool. It looks something like this Start a new pool named www. Per pool prefix. It only applies on the following directives. When not set, the global prefix or usr applies instead. Note This directive can also be relative to the global prefix. Default Value none. Unix usergroup of processes. Note The user is mandatory. If the group is not set, the default users group. The address on which to accept Fast. CGI requests. Valid syntaxes are. TCP socket to a specific address on. TCP socket to all addresses on a. Note This value is mandatory. Set listen2 backlog. Default Value 1. Free. BSD and Open. BSD. The above thing consists of comments mostly and the most important 4 lines are. This socket must be given to nginx for nginx to be able to talk to fpm. Connect fpm with nginx. We are not going to change much here. Just note down the socket path. We have to put this into the nginx configuration file. Go back to your nginx configuration and open it again. It contains a section for php fpm configuration which looks like this pass the PHP scripts to Fast. CGI server listening on 1. NOTE You should have cgi. With php. 5 cgi alone. With php. 5 fpm. Uncomment it and make it look like thislocation. NOTE You should have cgi. With php. 5 cgi alone. With php. 5 fpm. Test PHPNow put up a file in the web root with the phpinfo call. And then open the file in browser and the php information block should come up, saying that php is setup and working correctly. Another thing that you can do is add index. So that when accessing a directory, if no file is specified, then index. Setup apc alternate php cache. APC is a great way to speed up the execution of php scripts. Apc compiles php code and keeps the opcode in memory and uses it next time without compiling the same php code again from file. This drastically speeds up execution. Apart from opcode cache, apc also offers a user cache to store raw data for the php application in memory. Php as of version 5. How to Install LDAP 3. Directory Server On Linux with Detailed Steps.
