java -jar selenium-server-standalone-3.3.1.jar -help

Usage: <main class> [options]
  Options:
    --version, -version
       Displays the version and exits.
       Default: false
    -browserTimeout
       <Integer> in seconds : number of seconds a browser session is allowed to
       hang while a WebDriver command is running (example: driver.get(url)). If the
       timeout is reached while a WebDriver command is still processing, the session
       will quit. Minimum value is 60. An unspecified, zero, or negative value means
       wait indefinitely.
       Default: 0
    -debug
       <Boolean> : enables LogLevel.FINE.
       Default: false
    -jettyThreads, -jettyMaxThreads
       <Integer> : max number of threads for Jetty. An unspecified, zero, or
       negative value means the Jetty default value (200) will be used.
    -log
       <String> filename : the filename to use for logging. If omitted, will log
       to STDOUT
    -port
       <Integer> : the port number the server will use.
       Default: 4444
    -role
       <String> options are [hub], [node], or [standalone].
       Default: standalone
    -timeout, -sessionTimeout
       <Integer> in seconds : Specifies the timeout before the server
       automatically kills a session that hasn't had any activity in the last X seconds. The
       test slot will then be released for another test to use. This is typically
       used to take care of client crashes. For grid hub/node roles, cleanUpCycle
       must also be set.
       Default: 1800

对于hub角色的帮助

java -jar selenium-server-standalone-3.3.1.jar -role hub -help

Usage: <main class> [options]
  Options:
    --version, -version
       Displays the version and exits.
       Default: false
    -browserTimeout
       <Integer> in seconds : number of seconds a browser session is allowed to
       hang while a WebDriver command is running (example: driver.get(url)). If the
       timeout is reached while a WebDriver command is still processing, the session
       will quit. Minimum value is 60. An unspecified, zero, or negative value means
       wait indefinitely.
       Default: 0
    -matcher, -capabilityMatcher
       <String> class name : a class implementing the CapabilityMatcher
       interface. Specifies the logic the hub will follow to define whether a request can
       be assigned to a node. For example, if you want to have the matching process
       use regular expressions instead of exact match when specifying browser
       version. ALL nodes of a grid ecosystem would then use the same capabilityMatcher,
       as defined here.
       Default: org.openqa.grid.internal.utils.DefaultCapabilityMatcher@64a294a6
    -cleanUpCycle
       <Integer> in ms : specifies how often the hub will poll running proxies
       for timed-out (i.e. hung) threads. Must also specify "timeout" option
       Default: 5000
    -custom
       <String> : comma separated key=value pairs for custom grid extensions.
       NOT RECOMMENDED -- may be deprecated in a future revision. Example: -custom

       negative value means the Jetty default value (200) will be used.
    -log
       <String> filename : the filename to use for logging. If omitted, will log
       to STDOUT
    -maxSession
       <Integer> max number of tests that can run at the same time on the node,
       irrespective of the browser used
    -newSessionWaitTimeout
       <Integer> in ms : The time after which a new test waiting for a node to
       become available will time out. When that happens, the test will throw an
       exception before attempting to start a browser. An unspecified, zero, or negative

       Default: 4444
    -prioritizer
       <String> class name : a class implementing the Prioritizer interface.
       Specify a custom Prioritizer if you want to sort the order in which new session
       requests are processed when there is a queue. Default to null ( no priority = FIFO
       )
    -role
       <String> options are [hub], [node], or [standalone].
       Default: hub
    -servlet, -servlets
       <String> : list of extra servlets the grid (hub or node) will make
       available. Specify multiple on the command line: -servlet tld.company.ServletA
       -servlet tld.company.ServletB. The servlet must exist in the path:
       /grid/admin/ServletA /grid/admin/ServletB
       Default: []
    -timeout, -sessionTimeout
       <Integer> in seconds : Specifies the timeout before the server
       automatically kills a session that hasn't had any activity in the last X seconds. The
       test slot will then be released for another test to use. This is typically
       used to take care of client crashes. For grid hub/node roles, cleanUpCycle
       must also be set.
       Default: 1800
    -throwOnCapabilityNotPresent
       <Boolean> true or false : If true, the hub will reject all test requests
       if no compatible proxy is currently registered. If set to false, the request
       will queue until a node supporting the capability is registered with the grid.
       Default: true
    -withoutServlet, -withoutServlets
       <String> : list of default (hub or node) servlets to disable. Advanced
