upstart 无法运行服务并且无法调试

我在用os-svc-daemon为 openstack 项目创建我的 upstart 服务。

我的 upstart 工作配置如下

文件：/etc/init/myservice.conf

start on runlevel [2345]
stop on runlevel [016]


env OS_SVC_ENABLE_CONTROL=1
export OS_SVC_ENABLE_CONTROL

pre-start script
  mkdir -p /var/run/myservice
  chown -R root:root /var/run/myservice
end script

respawn
# the default post-start of 1 second sleep delays respawning enough to
# not hit the default of 10 times in 5 seconds. Make it 2 times in 5s.
respawn limit 2 5

exec start-stop-daemon --start -c root --exec /opt/stack/venvs/openstack/bin/myservice --

post-start exec sleep 1

该服务以 root 用户身份运行。

如果我运行start-stop-daemon --start -c root --exec /opt/stack/venvs/openstack/bin/myservice它就运行正常。

但是当我使用检查状态时

~# initctl start myservice
myservice stop/starting

~# initctl status myservice
myservice stop/waiting

我也试过调试

start on runlevel [2345]
stop on runlevel [016]


env OS_SVC_ENABLE_CONTROL=1
export OS_SVC_ENABLE_CONTROL

pre-start script      
  mkdir -p /var/run/myservice
  chown -R root:root /var/run/myservice
end script

script
  echo "DEBUG: `set`" >> /tmp/myjob.log

  # rest of script follows...
end script    

respawn
# the default post-start of 1 second sleep delays respawning enough to
# not hit the default of 10 times in 5 seconds. Make it 2 times in 5s.
respawn limit 2 5

exec start-stop-daemon --start -c root --exec /opt/stack/venvs/openstack/bin/myservice --

post-start exec sleep 1

但它不是在创建文件/tmp

我猜你的命令之一启动前脚本失败（可能是 mkdir）。尝试附加“|| true”

pre-start script      
  mkdir -p /var/run/myservice || true
  chown -R root:root /var/run/myservice || true
end script

您应该看到进程号出现在initctl start myservice命令之后
