停止/重启 Gearmand答案

【问题标题】：Stopping/Rebooting Gearmand停止/重启 Gearmand

【问题描述】：

我已经在我的 Ubuntu 上安装了 Gearman Job Server（又名 Gearmand）1.0.6：

Distributor ID: Ubuntu
Description:    Ubuntu 14.04.2 LTS
Release:        14.04

我还安装了 gearman-tools、libgearman-dev。尝试使用命令重启 Gearmand：

/etc/init.d/gearman-job-server restart

但我收到一个错误：

 No /usr/sbin/gearmand found running; none killed.
 /usr/sbin/gearmand already running.

当我试图阻止它时也会发生同样的情况：

/etc/init.d/gearman-job-server stop

回复：No /usr/sbin/gearmand found running; none killed.

/etc/init.d/gearman-job-server 代码为：

谷歌没有帮助......也许搜索错误的方式。你能帮我让它工作吗？ :)

【解决方案1】：

好的，我找到了解决问题的方法。我发现 Gearman 有很多错误。问题是它没有创建 PID 表单暴发户，也没有使用来自/etc/default/gearman-job-server 的配置。希望它会帮助某人。将/etc/init/gearman-job-server.conf 编辑为：

# -*- upstart -*-

# Upstart configuration script for "gearman-job-server".

description "gearman job control server"

start on (filesystem and net-device-up IFACE=lo)
stop on runlevel [!2345]

respawn
expect fork

pre-start script
    mkdir -p -m 0775 /var/run/gearman
    chown gearman:gearman /var/run/gearman
end script

script
    . /etc/default/gearman-job-server
    exec start-stop-daemon --start --exec /usr/sbin/gearmand -- $PARAMS
end script

【解决方案2】：

只需在 /etc/init.d/gearman-server 中的 stop 函数处执行以下操作：

#  if start-stop-daemon \
#    --stop \
#    --oknodo \
#    --exec $DAEMON \
#    --pidfile $PIDFILE
  if /usr/local/bin/gearadmin --shutdown
