我参加了一个教程http://craiccomputing.blogspot.com/2010/10/passenger-3-nginx-and-rvm-on-mac-os-x.html一切正常。没有错误。
Nginx with Passenger support was successfully installed.
The Nginx configuration file (/opt/nginx/conf/nginx.conf)
must contain the correct configuration options in order for Phusion Passenger
to function correctly.
This installer has already modified the configuration file for you! The
following configuration snippet was inserted:
http {
...
passenger_root /home/alex/.rvm/gems/ruby-1.9.3-p194/gems/passenger-3.0.14;
passenger_ruby /home/alex/.rvm/wrappers/ruby-1.9.3-p194/ruby;
...
}
After you start Nginx, you are ready to deploy any number of Ruby on Rails
applications on Nginx.
但我无法启动它。
alex@ubuntu:~$ sh -x /etc/init.d/nginx start
sh: 0: Can't open /etc/init.d/nginx
sudo /etc/init.d/nginx start
sudo: /etc/init.d/nginx: command not found
该目录opt/nginx
存在,并且其中有文件。Localhost:80
也不起作用。
有什么建议么?

安装 Rails + NGINX + Passenger + RVM 设置的常用方法通常涉及将 nginx 放置在 /opt/nginx 中,但实际上它不会创建 init.d 启动文件。这篇博文展示了如何轻松地从利诺德:
wget -O init-deb.sh https://www.linode.com/docs/assets/660-init-deb.sh
sudo mv init-deb.sh /etc/init.d/nginx
sudo chown root:root /etc/init.d/nginx
sudo chmod +x /etc/init.d/nginx
sudo /usr/sbin/update-rc.d -f nginx defaults
为了方便以后参考,以下是来自 Linode 的脚本:
#! /bin/sh
### BEGIN INIT INFO
# Provides: nginx
# Required-Start: $all
# Required-Stop: $all
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: starts the nginx web server
# Description: starts nginx using start-stop-daemon
### END INIT INFO
PATH=/opt/nginx/sbin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/opt/nginx/sbin/nginx
NAME=nginx
DESC=nginx
test -x $DAEMON || exit 0
# Include nginx defaults if available
if [ -f /etc/default/nginx ] ; then
. /etc/default/nginx
fi
set -e
case "$1" in
start)
echo -n "Starting $DESC: "
start-stop-daemon --start --quiet --pidfile /opt/nginx/logs/$NAME.pid \
--exec $DAEMON -- $DAEMON_OPTS
echo "$NAME."
;;
stop)
echo -n "Stopping $DESC: "
start-stop-daemon --stop --quiet --pidfile /opt/nginx/logs/$NAME.pid \
--exec $DAEMON
echo "$NAME."
;;
restart|force-reload)
echo -n "Restarting $DESC: "
start-stop-daemon --stop --quiet --pidfile \
/opt/nginx/logs/$NAME.pid --exec $DAEMON
sleep 1
start-stop-daemon --start --quiet --pidfile \
/opt/nginx/logs/$NAME.pid --exec $DAEMON -- $DAEMON_OPTS
echo "$NAME."
;;
reload)
echo -n "Reloading $DESC configuration: "
start-stop-daemon --stop --signal HUP --quiet --pidfile /opt/nginx/logs/$NAME.pid \
--exec $DAEMON
echo "$NAME."
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start|stop|restart|reload|force-reload}" >&2
exit 1
;;
esac
exit 0
需要注意的一点是:如果您更改了 nginx.pid 位置(默认为 /opt/nginx/log,我将其更改为 /var/run),则需要在此文件中进行更改。在顶部附近,只需将其声明为变量即可:
PIDPATH=/var/run/$NAME.pid
并将任何具有 pid 路径的位置替换为 $PIDPATH。(即使您保留原始路径,这也会使得脚本更具可读性)。

正常安装方式nginx是通过apt-get
(或 Synaptic 或 SW Center),据我所知,这不会放入任何内容/opt
。在这种情况下,您只需发出以下命令即可停止/启动它:
sudo service nginx start|stop|restart (etc)
如果您nginx
自行安装在/opt
,我怀疑它会触及/etc/init.d
目录......

我建议使用Brightbox PPA提到维基百科. 这使得所有正常服务处理都像开箱service nginx start
即用一样。/etc/init.d/nginx start
对于我来说,这在精确(12.04 LTS)中运行良好。
