traffic_ctl does IPC over a UNIX pipe to communicate with traffic_manager which will, if needed, communicate with traffic_server. The file name of the pipe is a compile time constant in traffic_ctl and traffic_manager. Therefore which Traffic Server instance is affected is based on which traffic_ctl binary you use.On Monday, March 27, 2017, 8:12:56 PM CDT, salil GK <email@example.com> wrote:
I have a doubt regarding the traffic_ctl command. In my setup I am running two instances of traffic server. This I am doing by specifying two different directories for configuration. Now when I run traffic_ctl how do I control the configuration reload. I mean traffic_ctl need to read the correct configuration file and update the variables of respective instance. How do I do this ?
How does the trfficctl update the configuration variables of traffic_server – is it some IPC mechanism ?
