Reload

Almost all features of SRS support reload, donot disconnect all connection and apply the new config.

NotSupportedFeatures

The bellow features can not reload:

• deamon: whether start as deamon mode.
• mode: the mode of vhost.

The daemon never support reload.

The mode of vhost, to make the vhost origin or edge, should never directly change the mode, because of:

• The origin and edge switch is too complex.
• The origin always put in a device group, never change to edge actually.
• The upnode or origin restart have no effect to user, edge will retry.

A workaround to modify the mode of vhost:

• Delete the vhost and reload.
• Ensure the vhost is deleted, for the reload is async.
• Add vhost with new mode, then reload.

Use Scenario

The use scenario of reload:

• Donot restart server to apply new config, only killall -1 srs.
• Donot disconnect user connections.

Usage

The usage of reload: killall -1 srs

Or send signal to process: kill -1 7635

Or use SRS scripts: /etc/init.d/srs reload
