I was able to install and run nginx, and passenger but i'm not able to have nginx come up whenever i reboot my server. To start the nginx process i just type in sudo /opt/nginx/sbin/nginx. From my understanding anything i put in /etc/init.d with ubuntu hardy will be execute. Does anyone know the command that will mimic this command line call?
sudo /opt/nginx/sbin/nginx
To start nginx on boot: sudo systemctl enable nginx (doesn't start it immediately)
To start nginx: sudo systemctl start nginx
Thanks for the info, if someone wants step by step instructions. Go to /etc/init.d and run sudo nano nginx-passenger.sh, then paste in this code:
#!/bin/bash
# this script starts the nginx process attached to passenger
sudo /opt/nginx/sbin/nginx
save and exit. Make the file executable by typing sudo chmod +x /etc/init.d/nginx-passenger.sh. You can test to see if the script works by typing sudo /etc/init.d/nginx-passenger.sh this will run all the code in the script. Verify that it launches nginx before continuing.
Then run sudo update-rc.d nginx-passenger.sh defaults while still in the /etc/init.d directory. Once all of this is in place, reboot your server and ngnix should now be automatically spawned on startup
/etc/init.d is just the location for the start up scripts to live. But having a script there doesn't do anything automatically.
The init system uses the symbolic links in the /etc/rc#.d directories to the scripts in the /etc/init.d folder. The name of the symbolic link needs to start with an S to run the script with the start option and K to run the stop option followed by a priority number and then the name of the script.
See the following for more info
/etc/init.d/README
/etc/rc1.d/README
/etc/rc2.d/README
Alternatively you can put your command you want to run into the /etc/rc.local script which is run after the system boots and finishes executing all the scripts in the /etc/rc2.d/ folder.
I am assuming you have installed nginx
If you have nginx running then stop the process using:
sudo kill `cat /usr/local/nginx/logs/nginx.pid` Init script
The script shown below is from an Ubuntu 10.04 install and has been adapted to take into account our custom install of nginx. Please create the script:
sudo nano /etc/init.d/nginx
Inside the blank file place the following:
#! /bin/sh
### BEGIN INIT INFO
# Provides: nginx
# Required-Start: $all
# Required-Stop: $all
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6

# Description: starts nginx using start-stop-daemon
### END INIT INFO

. /etc/default/nginx

echo -n "Starting $DESC: "

Execute As the init file is a shell script, it needs to have executable permissions.
We set them like so:
sudo chmod +x /etc/init.d/nginx
update-rc Now we have the base script prepared, we need to add it to the default run levels:
sudo /usr/sbin/update-rc.d -f nginx defaults
The output will be similar to this:
sudo /usr/sbin/update-rc.d -f nginx defaults
Adding system startup for /etc/init.d/nginx ...
/etc/rc0.d/K20nginx -> ../init.d/nginx
/etc/rc1.d/K20nginx -> ../init.d/nginx
/etc/rc6.d/K20nginx -> ../init.d/nginx
/etc/rc2.d/S20nginx -> ../init.d/nginx
/etc/rc3.d/S20nginx -> ../init.d/nginx
/etc/rc4.d/S20nginx -> ../init.d/nginx
/etc/rc5.d/S20nginx -> ../init.d/nginx
Now we can start, stop and restart nginx just as with any other service:
sudo /etc/init.d/nginx start
...
sudo /etc/init.d/nginx stop
...
sudo /etc/init.d/nginx restart
The script will also be called on a reboot so nginx will automatically start.
My nginx is a self-compiled version provided with Passenger. No init scripts were included.
Nginx provides a systemd service file:
[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target
[Service]
Type=forking
PIDFile=/run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t
ExecStart=/usr/sbin/nginx
ExecReload=/usr/sbin/nginx -s reload
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target
I had to edit the paths and signals to fit my installation. For a CentOS system, like mine, the file path should be /etc/systemd/system/nginx.service.
I use this script to start a passenger-backed nginx:
http://library.linode.com/development/frameworks/ruby/ruby-on-rails/nginx-ubuntu-8.04-hardy
Check this link:
https://github.com/JasonGiedymin/nginx-init-ubuntu
They provide a nginx init.d script to run in ubuntu.
For reference: I just followed the instructions and script for Maverick provided by Linode at http://library.linode.com/frameworks/ruby-on-rails-nginx/ubuntu-10.10-maverick
