我正在尝试为unicorn(在Ubuntu上)运行一个init脚本,并将unicorn安装为gem:
/home/tim/.rvm/gems/ruby-1.9.2-p180@polco/bin/unicorn
我的初始化脚本是:
#! /bin/sh ### BEGIN INIT INFO # Provides: unicorn # Required-Start: $local_fs $remote_fs $network $syslog # Required-Stop: $local_fs $remote_fs $network $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: starts the unicorn web server # Description: starts unicorn ### END INIT INFO PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin DAEMON=/home/tim/.rvm/gems/ruby-1.9.2-p180@polco/bin/unicorn DAEMON_OPTS="-c /home/deployer/shop/current/unicorn.rb -E production -D" NAME=unicorn_rails DESC=unicorn_rails PID=/home/deployer/shop/shared/pids/unicorn.pid case "$1" in start) echo -n "Starting $DESC: " $DAEMON $DAEMON_OPTS echo "$NAME." ;; stop) echo -n "Stopping $DESC: " kill -QUIT `cat $PID` echo "$NAME." ;; restart) echo -n "Restarting $DESC: " kill -QUIT `cat $PID` sleep 1 $DAEMON $DAEMON_OPTS echo "$NAME." ;; reload) echo -n "Reloading $DESC configuration: " kill -HUP `cat $PID` echo "$NAME." ;; *) echo "Usage: $NAME {start|stop|restart|reload}" >&2 exit 1 ;; esac exit 0
使用rvm可执行文件,整个操作对我来说似乎很脆弱。 rvm有类似$ CURRENT_RVM_PATH吗?

O.k。我为我解决了这个问题。如果我是root用户,我就不再关心了,并且决定以讽刺的方式运行这个用户“乘客”并且我需要运行unicorn_rails。
这是我的启动脚本:
#! /bin/sh ### BEGIN INIT INFO # Provides: unicorn # Required-Start: $local_fs $remote_fs $network $syslog # Required-Stop: $local_fs $remote_fs $network $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: starts the unicorn web server # Description: starts unicorn ### END INIT INFO PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin #DAEMON=/home/tim/.rvm/gems/ruby-1.9.2-p180@polco/bin/unicorn DAEMON=/home/passenger/.rvm/gems/ruby-1.9.2-p180/bin/unicorn_rails DAEMON_OPTS="-c /home/passenger/polco/current/config/unicorn_tacitus.rb -E production -D" NAME=unicorn_rails DESC=unicorn_rails PID=/home/passenger/polco/shared/pids/unicorn.pid case "$1" in start) echo -n "Starting $DESC: " $DAEMON $DAEMON_OPTS echo "$NAME." ;; stop) echo -n "Stopping $DESC: " kill -QUIT `cat $PID` echo "$NAME." ;; restart) echo -n "Restarting $DESC: " kill -QUIT `cat $PID` sleep 1 $DAEMON $DAEMON_OPTS echo "$NAME." ;; reload) echo -n "Reloading $DESC configuration: " kill -HUP `cat $PID` echo "$NAME." ;; *) echo "Usage: $NAME {start|stop|restart|reload}" >&2 exit 1 ;; esac exit 0
要执行此操作 - 我现在有简单的capistrano任务:
desc "restart unicorn" task :restart, :roles => :app, :except => { :no_release => true } do run "#{current_path}/unicorn_exec restart" end after "deploy:restart","unicorn:restart"
最后一个问题我是为什么我必须重启unicorn_rails。我以为我可以通过以下方式重新加载:kill -HUP cat $PID
,但是一切只有在重新启动时才有效。

由于谷歌可能会为其他人找到这个问题,这是我在3台不同服务器上使用的独角兽重启脚本。我只需要添加USR2。回购被称为eunic,我可能会在以后修改它。
这就是说,这是另一种方法。
