Compiling uWSGI from sources
As you probably know, uWSGI is a fast application container for serving your webapps. It is often used with Django against nginx webserver. Written in pure C & having a lot of other cool features.
It seems that installation of uWSGI is pretty simple according to official docs but it isn’t.
If you want to deploy your Django app on a brand new linux box (VPS/Amazon EC2), using buildout without a lot of dependencies things become more complicated.
Here is how you can tune up your uWSGI:
wget http://projects.unbit.it/downloads/uwsgi-0.9.7.2.tar.gz tar -xvvf uwsgi-0.9.7.2.tar.gz cd uwsgi-0.9.7.2
If you’ll simply run make as this point, you’ll experience something like this:
*** libxml2 headers unavailable. uWSGI build is interrupted. You have to install libxml2 development package or use libexpat or disable XML
Since uWSGI needs libxml2 for reading XML configs, which is only one of the available configuration options (command line, environment variables, XML, .ini, yaml files and via LDAP.), we’re going to drop this dependency (I’m more comfortable with command-line style)
It’s not obvious how to drop libxml2 dependency, because there’s no configure & usual C-style make. Instead, build is fully controlled by uwsgiconfig.py script, which you can grok for a while to get a grasp on how the whole process works.
Build options are stored in buildconf/ folder:
root@devbox:~/server/thirdparty/uwsgi-0.9.7.2# ls -l buildconf/ total 64 -rw-r--r-- 1 root root 50 Apr 6 10:50 core.ini -rw-r--r-- 1 root root 497 Apr 6 10:50 default.ini -rw-r--r-- 1 root root 54 Apr 6 10:50 erlang.ini -rw-r--r-- 1 root root 49 Apr 6 10:50 lua.ini -rw-r--r-- 1 root root 40 Apr 6 10:50 luap.ini -rw-r--r-- 1 root root 485 Apr 6 10:50 modular.ini -rw-r--r-- 1 root root 78 Apr 6 10:50 package.ini -rw-r--r-- 1 root root 50 Apr 6 10:50 psgi.ini -rw-r--r-- 1 root root 60 Apr 6 10:50 pyerl.ini -rw-r--r-- 1 root root 86 Apr 6 10:50 pylua.ini -rw-r--r-- 1 root root 462 Apr 6 10:50 pyrb.ini -rw-r--r-- 1 root root 69 Apr 6 10:50 rack.ini -rw-r--r-- 1 root root 449 Apr 6 10:50 rackp.ini -rw-r--r-- 1 root root 377 Apr 6 10:50 unbit.ini -rw-r--r-- 1 root root 108 Apr 6 10:50 unbitstaff.ini
For our customized build we’ll create a new build config, called myproject.ini:
root@devbox:~/server/thirdparty/uwsgi-0.9.7.2/buildconf# cp default.ini myproject.ini
He’re how internals should look like if you want to turn off libxml2 support:
[uwsgi] xml = false ini = true yaml = true snmp = true sctp = false spooler = true embedded = true udp = true multicast = true threading = true sendfile = true minterpreters = true async = true evdis = false ldap = auto pcre = auto debug = false unbit = false ; xml_implementation = libxml2 plugins = bin_name = uwsgi plugin_dir = . embedded_plugins = python, ping, nagios, rpc, fastrouter, http, ugreen locking = auto event = auto timer = auto filemonitor = auto [python] paste = true web3 = true
At this point you’re ready to type
python uwsgiconfig.py --build myproject
In theory this should build you a brand-new uWSGI, but only in theory. Probably, what you’ll get by doing above command will be:
