High memory usage in webfaction

[Joseph Jude]

Dear All,

I was expecting when I am going to get this message from webfaction team and I got it today. I have searched through this group and found that I could use uwsgi server. Before I go ahead and make changes on the site, I got few questions:

1. Currently it is running on apache. How do I make the switch to uwsgi and disable apache?

2. In the error message that webfaction sent, there are processes that running for 23 days (and there are many) and that adds to the memory. How do I know what are the unnecessary processes and kill them?

3. There is a expire_sessions.py in admin app. Does that help and if so, how?

Thank you,

Joseph

hi,

 Currently it is running on apache. How do I make the switch to uwsgi and disable apache?

go to webfaction panel and do 2 things:

- remove app that is running on top of apache

-  create a custom app listening on a port 

then connect via ssh to your webfaction account and do that

[install web2py]

wget http://www.web2py.com/examples/static/web2py_src.zip

unzip web2py_src.zip  

python2.7 web2py.py

cd /home/your_user

[install uwsgi]

wget http://projects.unbit.it/downloads/uwsgi-1.0.2.1.tar.gz

tar xvzf uwsgi-1.0.2.1.tar.gz

cd uwsgi-1.0.2.1

/home/your_user/bin/python2.7 uwsgiconfig.py --build

mv uwsgi /home/your_user/bin

cd /home/your_user

[start uwsgi]

uwsgi --http 127.0.0.1:your_custom_port --pythonpath /home/your_user /web2py --module wsgihandler -d /home/your_user/tmp/uwsgi.log -t 20 -r --no-orphans -M -p 2 --touch-reload /home/your_user/tmp/uwsgireload.txt --evil-reload-on-rss 100

 How do I know what are the unnecessary processes and kill them?

 

ps -u your_user -o rss,command

that will show you your processes and how much memory they use

ps -u your_user

will show ids of processes

and

kill -9 id_of_process

oh my god.  The memory usage dropped from 71 mb from 120 mb. webfaction should use this as their default for installing web2py.

I can't thank you enough.

Just one more question:

1. I'm assuming there is no need to restart uwsgi; it automatically does I suppose?

Thank you,

Joseph

"dropped from 71 mb from 120 mb"

which of the two numbers has a typo? :-)

[Joseph Jude]

sorry it is midnight here and i am too relieved that it is solved and too excited that now i can get back to 'real' development.

dropped to 71 mb from 120 mb

I'm assuming there is no need to restart uwsgi; it automatically does I suppose?

 it is started with this command

uwsgi --http 127.0.0.1:your_custom_port --pythonpath /home/your_user /web2py --module wsgihandler -d /home/your_user/tmp/uwsgi.log -t 20 -r --no-orphans -M -p 2 --touch-reload /home/your_user/tmp/uwsgireload.txt --evil-reload-on-rss 100

it is running as a daemon, which means it is still running after you close ssh window (putty in my case)

can I rotate log (uwsgi.log) with this command? I don't want the log file to go on increasing in size

log-maxsize = n

where n is the maximum size in bytes
