nginx & uwsgi(psgi) & perlbrew & mojolicious
!!! Warn !!! Incomplete still !!!
Доброго всем !
¡ ¡ ¡ ALL GLORY TO GLORIA ! ! !
perlbrew is a tool to manage multiple perl installations in your $HOME directory. They are completely isolated perl universes.
$ curl -kL http://install.perlbrew.pl | bash $ echo 'source ~/perl5/perlbrew/etc/bashrc' >> .bash_profile # choose mirror $ perlbrew mirror $ perlbrew available # choose version $ perlbrew install perl-5.16.2 $ perlbrew use perl-5.16.2 # or switch $ perlbrew install-cpanm $ cpanm App::cpanoutdated $ cpanm <Your::Favorite::Modules> $ cpanm ... # регулярно обновляться (regulary run update installed modules) $ cpan-outdated | cpanm
$ crontab -e
30 2 * * * perlbrew self-upgrade; perlbrew upgrade-perl 0 3 * * * perlbrew exec --with perl-5.16.2 cpan-outdated | cpanm # or 0 3 * * * perlbrew exec --with perl-5.16.2 perlbrew list-modules | cpanm
$ cpanm Mojo
An usual procedure for new Mojolicious app
$ mojo generate app Service1 $ service1/script/service1 test $ service1/script/service1 daemon # or $ morbo service1/script/service1 # or $ hypnotoad service1/script/service1 start # all glory to ...
Go in favorite browser http://127.0.0.1:3000 or http://localhost:8080/
And work, work, work on new app...
Below will install production bundle nginx+uwsgi(psgi) for our Mojolicious application.
Uwsgi daemon will load Mojolicious app in PSGI. No changes in the structure of the our application will not need. Mojolicious will autodetect PSGI mode.
You can compile and install uwsgi with psgi support using the "network installer". Make sure perlbrew set right Perl version (perl-5.16.2)
$ perlbrew info $ curl http://uwsgi.it/install | bash -s psgi ~/uwsgi-perl-5.16.2The new uwsgi server binary file name indicate linked with appropriate version of perl
#!/bin/bash
# Use uwsgi to run psgi web apps.

Note. Uwsgi have --declare-option which would be usefull for pass args to the Mojolicious app, but it didnt work on my tests. Configure your app with Mojolicious::Plugin::Config
Crontab for reload uwsgi Mojolicious app with every night updated perl modules (see above)

The nginx interacts with uwsgi daemon through unix socket /tmp/uwsgi.sock.1
Go to http://your.domain/
Looks awesome!
