Monit & Rails sunspot_solr

Question

我已经设置了monit来监视我的sunspot_solr过程，这个过程一开始似乎很有效。如果我用sudo service monit restart重新启动monit服务，我的太阳黑子进程就会启动：

 ps aux | grep sunspot

​

但是，我也在运行tail -f /var/logs/monit.log并同时看到了以下内容：

​

[CST Mar  3 12:42:54] error    : 'sunspot_solr' process is not running
[CST Mar  3 12:42:54] info     : 'sunspot_solr' trying to restart
[CST Mar  3 12:42:54] info     : 'sunspot_solr' start: /usr/bin/sudo
[CST Mar  3 12:43:25] error    : 'sunspot_solr' failed to start

​

此外，为了确保monit能够实际重新启动sunspot_solr进程，我运行sudo kill -9 <the pid>，monit不能重新启动sunspot_solr：

​

[CST Mar  3 12:44:25] error    : 'sunspot_solr' process is not running
[CST Mar  3 12:44:25] info     : 'sunspot_solr' trying to restart
[CST Mar  3 12:44:25] info     : 'sunspot_solr' start: /usr/bin/sudo
[CST Mar  3 12:44:55] error    : 'sunspot_solr' failed to start

​

显然，我的monit-solr_sunspot.conf文件有问题，但在处理了几个小时之后，我感到很困惑：

​

check process sunspot_solr with pidfile /ebs/staging/shared/pids/sunspot-solr.pid
  start program = "/usr/bin/sudo -H -u root /bin/bash -l -c 'cd /ebs/staging/releases/20160226191542; bundle exec sunspot-solr start -- -p 8983 -d /ebs/staging/shared/solr/data --pid-dir=/ebs/staging/shared/pids'"
  stop program = "/usr/bin/sudo -H -u root /bin/bash -l -c 'cd /ebs/staging/releases/20160226191542; bundle exec sunspot-solr stop -- -p 8983 -d /ebs/staging/shared/solr/data --pid-dir=/ebs/staging/shared/pids'"

​

我已经修改了这个monit脚本来满足我的需要：太阳黑子样品-太阳黑子，但是仍然没有运气！

UPDATE --如果我杀死了它，那么monit就可以成功地重新启动sunspot_solr，但是它仍然会产生错误，导致它在monit.log文件中重新启动失败。

我认为monit作为根运行。您可能不想使用sudo，这既是因为它提示输入密码，也因为monit不需要它。
