Installing Web2py with Nginx and Uwsgi on Centos 5 is really tricky. There are lots of subtleties of ownership, and one has to take care when installing python 2.6 not to stop the systems python2.4 from working. I have finally developed a script that does all the installation from a clean start machine. The only thing that should need changing for another installation is the $basearch (base architecture) of the machine. This can be determined by doing 'uname -i'. This is needed for the nginx installation.
-------------------------------------------------------------------------------------------- # install development tools yum install gcc gdbm-devel readline-devel ncurses-devel zlib-devel bzip2-devel sqlite-devel db4-devel openssl-devel tk-devel bluez-libs-devel #Install python 2.6 without overwriting python 2.4 #================================= VERSION=2.6.8 mkdir ~/src chmod 777 ~/src cd ~/src wget http://www.python.org/ftp/python/$VERSION/Python-$VERSION.tgz tar xvfz Python-2.6.8.tgz cd Python-2.6.8 ./configure --prefix=/opt/python2.6 --with-threads --enable-shared make #The altinstall ensures that python2.4 is left okay make altinstall echo "/opt/python2.6/lib">/etc/ld.so.conf.d/opt-python2.6.conf ldconfig #create alias so that python 2.6 can be run with 'python2.6' alias -p python2.6="/opt/python2.6/bin/python2.6" ln -s /opt/python2.6/bin/python2.6 /usr/bin/python2.6 # Install uwsgi #========= version=uwsgi-1.2.3 cd /opt/ wget http://projects.unbit.it/downloads/$version.tar.gz tar -zxvf $version.tar.gz mv $version/ uwsgi/ cd uwsgi/ # build using python 2.6 python2.6 setup.py build python2.6 uwsgiconfig.py --build useradd uwsgi #create and own uwsgi log # Note this log will need emptying from time to time echo " ">/var/log/uwsgi.log chown uwsgi /var/log/uwsgi.log #Install web2py #========== cd /opt mkdir web-apps cd web-apps wget http://www.web2py.com/examples/static/web2py_src.zip unzip web2py_src.zip #set the ownership for web2py application to uwsgi cd web2py chown -R uwsgi applications chmod -R u+wx applications #Now install nginx #============ cd /etc/yum.repos.d echo "[nginx]">nginx.repo # in the line below replace 'i386' with the $basearch for your machine. echo "baseurl=http://nginx.org/packages/centos/5/i386/";>>nginx.repo echo "gpgcheck=0">>nginx.repo echo "enabled=1">>nginx.repo yum install nginx #We don't want the defaults, so remove them cd /etc/nginx/conf.d mv default.conf default.conf.o mv example_ssl.conf example_ssl.conf.o ---------------------------------------------------------------------------------------------------------------- The following configuration files are also needed The options for uwsgi are in the following file. It should be placed in /etc/uwsgi. Other options could be included. uwsgi_for_nginx.conf [uwsgi] uuid=uwsgi pythonpath = /opt/web-apps/web2py module = wsgihandler socket=127.0.0.1:9001 harakiri 60 harakiri-verbose enable-threads daemonize = /var/log/uwsgi.log ------------------------------------------------------------------------ The next configuration file is for nginx, and goes in /etc/nginx/conf.d It serves the static diretory of applications directly. I have not set up ssl because I access web2py admin by using ssh tunneling and the web2py rocket server. It should be straightforward to set up the ssl server however. web2py.conf server { listen 80; server_name $hostname; location ~* /(\w+)/static/ { root /opt/web-apps/web2py/applications/; } location / { uwsgi_pass 127.0.0.1:9001; include uwsgi_params; } } #server { #listen 443; #server_name $hostname; #ssl on; #ssl_certificate /etc/nginx/ssl/web2py.crt; #ssl_certificate_key /etc/nginx/ssl/web2py.key; #location #uwsgi_pass 127.0.0.1:9001; #include uwsgi_params; #uwsgi_param UWSGI_SCHEME $scheme; #} #} ------------------------------------------------------------------------ The final configuration file is only needed if you want to run uwsgi as a service. It should be placed in /etc/init.d uwsgi_nginx #!/bin/bash # uwsgi - Use uwsgi to run python and wsgi web apps. # # chkconfig: - 85 15 # description: Use uwsgi to run python and wsgi web apps. # processname: uwsgi PATH=/opt/uwsgi:/sbin:/bin:/usr/sbin:/usr/bin DAEMON=/opt/uwsgi/uwsgi PYTHONPATH=/opt/web-apps/web2py MODULE=wsgihandler OWNER=uwsgi NAME=uwsgi DESC=uwsgi test -x $DAEMON || exit 0 # Include uwsgi defaults if available if [ -f /etc/default/uwsgi ] ; then . /etc/default/uwsgi fi set -e get_pid() { if [ -f /var/run/$NAME.pid ]; then echo `cat /var/run/$NAME.pid` fi } DAEMON_OPTS="--ini-paste /etc/uwsgi/uwsgi_for_nginx.conf" case "$1" in start) echo -n "Starting $DESC: " PID=$(get_pid) echo "$PID" echo "B" if [ -z "$PID" ]; then echo "C" [ -f /var/run/$NAME.pid ] && rm -f /var/run/$NAME.pid echo "D" echo "$PID" touch /var/run/$NAME.pid chown $OWNER /var/run/$NAME.pid su - $OWNER -pc "$DAEMON $DAEMON_OPTS" echo "$NAME." echo "$PID" fi ;; stop) echo -n "Stopping $DESC: " pkill $NAME # kill -9 `ps -fu uwsgi | awk 'NR != 1 {print $2}'` ;; reload) echo "Reloading $NAME" PID=$(get_pid) [ ! -z "$PID" ] && kill -s 1 $PID &> /dev/null if [ $? -gt 0 ]; then echo "was not running" exit 1 else echo "$NAME." rm -f /var/run/$NAME.pid &> /dev/null fi ;; force-reload) echo "Reloading $NAME" PID=$(get_pid) [ ! -z "$PID" ] && kill -s 15 $PID &> /dev/null if [ $? -gt 0 ]; then echo "was not running" exit 1 else echo "$NAME." rm -f /var/run/$NAME.pid &> /dev/null fi ;; restart) $0 stop sleep 2 $0 start ;; status) killall -10 $DAEMON ;; *) N=/etc/init.d/$NAME echo "Usage: $N {start|stop|restart|reload|force-reload|status}" >&2 exit 1 ;; esac exit 0 You can test it by /etc/init.d/uwsgi_nginx start and stop it similarly. To add it as a service do chkconfig --add uwsgi_nginx chkconfig uwsgi_nginx o You can test this with service uwsgi_nginx start nginx has automatically been set up as a service if you now start it with service nginx start you should find the web2py welcome app will be displayed at your web address. As they are both services, they should automatically start on a system reboot. If you already had a server running, such as apache, you would need to stop that and turn its service off before running nginx. ------------------------------ No virus found in this message.
