openstack各种服务的管理

后面没有*的是对应于usr/local/bin下的服务位置。
以neutron服务为例：
查看服务状态：systemctl status [email protected]
启动服务：systemctl status [email protected]
关闭服务：systemctl status [email protected]

scp [email protected]:/home/cpfer/Documents/local.conf ./

一、服务列表

二、服务相关内容：

当使用status查看服务的状态时，会有显示ExecStart。
neutron的显示如下。
ExecStart=/usr/local/bin/neutron-server --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini (code=exited, status=0/SUCCESS)
如果要用pdb调试neutron端的代码，可以拷贝这些路径（不包括后面括号的内容）
然后前面添加python -m pdb 运行即可。
如使用命令如下：
python -m pdb /usr/local/bin/neutron-server --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini
