Virtual Host

Default 

server {
  listen      80;
  listen      127.0.0.1:80;
  server_name localhost;
  root        /var/www;
  index       index.html index.htm;

  location / {
    index     index.html index.htm;
  }
}
  • For SSL 
server {
  listen      443 ssl;
  listen      127.0.0.1:443;
  server_name	localhost;
  root				/var/www;
  index       index.php index.html index.htm;

  ssl on;
  ssl_certificate /etc/ssl/certs/server.crt;
  ssl_certificate_key /etc/ssl/private/server.key;

  location / {
    index     index.php index.html index.htm;
  }
}
  • Restart Nginx 
$ sudo /etc/init.d/nginx restart

PHP 

$ sudo apt-get install php5-fpm

server {
  listen      80;
  listen      127.0.0.1:80;
  server_name localhost;
  root        /var/www;
  index       index.php index.html index.htm;

  location / {
    index     index.php index.html index.htm;
  }

  location ~ \.php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    include fastcgi_params;
  }
}
  • Restart php5-fpm 
$ sudo /etc/init.d/php5-fpm


Use with Tomcat 

server {
  listen      80;
  listen      127.0.0.1:80;
  server_name localhost;
  root        /var/www;

  location /manager {
    proxy_pass              http://localhost:8080;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        Host $http_host;
  }
}
  • Add a new file to /etc/nginx/sites-available/ 
server {
  listen          80;
  listen          127.0.0.1:80;
  server_name     demo.localhost;
  root            /path/to/tomcat/webapps;
  
  location / {
    proxy_pass              http://localhost:8080;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        Host $http_host;
  }

  location ~ ^/$ {
    rewrite  / /default-app;
  }
}

}

Site File 

server {

}

Run Trac Server

  • Without authentication 
sudo su www-data -c "tracd -d -p 3050 --pidfile=/opt/dev/nginx/run/tracd.3050 --protocol=http -e /opt/dev/trac"
  • With authentication 
sudo su www-data -c "tracd -d -p 3050 --pidfile=/opt/dev/nginx/run/tracd.3050 --protocol=http -e /opt/dev/trac --basic-auth=\"*,/path/to/.htpasswd/.htpasswd,Restricted\""

Run Script

  • Create directories 
$ cd /opt/dev 
$ mkdir nginx 
$ mkdir nginx/run
  • /opt/dev/nginx/trac-run.sh 
#!/bin/sh

#INSTANCES="3050 3051 3052 3053 3054 3055 3056"
INSTANCES="3050"
USER="www-data"
VERSION="1.0"
#ENV="/opt/dev/trac"
DEV_DIR="/opt/dev"
PIDFILE="${DEV_DIR}/nginx/run/tracd"
### Extra Args here, for instance --basic-auth
#ARGS="--basic-auth=*,${DEV_DIR}/.htpasswd/.htpasswd,Restricted"
ARGS="-e ${DEV_DIR}/trac"
PYTHON_EGG_CACHE="/tmp"


start(){
  export PYTHON_EGG_CACHE
  for I in $INSTANCES; do
      /bin/su ${USER} -c "/usr/local/bin/tracd -d -p ${I} --pidfile=${PIDFILE}.${I} --protocol=http ${ARGS} ${ENV}"
  done
}

stop(){
  if ls ${DEV_DIR}/nginx/run/tracd.* > /dev/null 2>&1; then
    for x in `ls ${PIDFILE}.*`; do
      echo "Killing process - PID: `cat ${x}`"
      kill `cat ${x}`
    done
  else
    echo "No PID exists"
  fi
}

$1


$ chmod a+x trac-run.sh 
$ cd /etc/init.d 
$ ln -s /opt/dev/nginx/trac-run.sh trac-run
  • Make the script run at bootup 
$ sudo update-rc.d trac-run defaults
