ServerSideJS: now easier than ever. Meet v8cgi!
v8cgi - a wrapper for the v8 JS engine from google. I was asked to put it on the server and he pleasantly surprised me with the unpredictable low gluttony and ease of use.
So, tasks:
1. Collect v8
2. Build v8cgi including as an Apache module
3. Configure the Apache.
4. Drink tea with caramel on this occasion.
Prerequisite: python, subversion and scons (gcc is everywhere).
For the inexperienced: svn, scons, python-minimal packages will work in debian
Taking the source code from SVN
and, going to the resulting folder, run the constructor.
Copy the newly collected file (libv8 * .so) to /usr/lib/libv8.so
')
Necessary: apache, mysql and GD libraries
(deb packages: libmysqlclient15-dev libgd2-dev apache2-threaded-dev)
Optional: sqlite and fastcgi (libfcgi-dev libsqlite3-dev)
Be sure to fix about the 58th line of the Sconfigure file ../v8 to ../V8, otherwise the constructor will be dissatisfied.
We collect:
Collected. We have 2 files: mod_v8cgi.so and v8cgi, copy them to / home / v8, and the contents of the lib directory in / usr / lib / v8cgi.
The libv8cgi.conf.posix config is copied to /etc/v8cgi.conf
add 3 lines with cofig and the module is working.
Regarding the launch as a cgi program.
In the errlolog, v8cgi swears for invalid headers and, as expected, drops 500 errors. Hands, what can you do :)
v8cgi earned with an unpredictable low memory consumption - 20-30 mb, against the expected 70-100.
JS received one more kick in the development of a completely different quality. Prospects? Horizons? Time will tell.
Oh. no caramels. No tea.
There is a very sour cherry. Fill it with boiling water and send some vitamins into the body :) By the way, not bad, I recommend.
