这一篇应该是mesos文档里面最难翻译的一篇，如何准确的去理解每一个配置选项正确的含义，需要对mesos有完整的理解，并且深入的实践.因为并不是每一个参数，都那么常用，甚至很多都很少被使用.这是一个长期的过程,此文档翻译暂停（最后做），请参考原文:http://mesos.apache.org/documentation/latest/configuration/
mesos配置
Mesos master和agent可以从命令行或环境变量接收一系列配置选项.通过运行`mesos-master --help`或者`mesos-agent --help`可以查看可用配置选项.每个选项都可以通过2个途径进行设置:
- 执行命令的时候，使用
`--option_name=value`，即直接指定选项值.或者指定一个包含选项的文件(--option_name=file://path/to/file).文件路径可以是绝对路径，也可以时相对当前目录的路径. - 通过设置环境变量
`MESOS_OPTION_NAME`，这些option都是以MESOS_为前缀
配置选项取值，先搜索环境变量，然后才是命令行.
重要的配置选项
如果你有特殊的编译需求，当你配置mesos时候，请参考`./configure --help`.这个文档只列出了最新版本的配置选项.如果你想查看你手上mesos版本命令的配置选项，请运行`命令 --help`,比如：` mesos-master --help`
master 和 agent 配置选项
| 参数 | 说明 |
|---|---|
| --advertise_ip=VALUE | Mesos master/agent对公发布的ip地址，这个ip地址不与master和agent绑定.这个ip地址用于访问该master/agent |
| --advertise_port=VALUE | master/agent对公发布的ip地址端口，这个ip地址端口不与master和agent绑定.这个ip地址端口用于访问该master/agent |
| --[no-]authenticate_http | If true, only authenticated requests for HTTP endpoints supporting authentication are allowed. If false, unauthenticated requests to HTTP endpoints are also allowed. (default: false) |
| --[no-]authenticate_http_frameworks | If true, only authenticated HTTP based frameworks are allowed to register. If false, HTTP frameworks are not authenticated. For more about HTTP frameworks see the Scheduler HTTP API documentation. (default: false) |
| --firewall_rules=VALUE | The value could be a JSON-formatted string of rules or a file path containing the JSON-formatted rules used in the endpoints firewall. Path must be of the form file:///path/to/file or /path/to/file. See the Firewall message in flags.proto for the expected format. Example: |
{
"disabled_endpoints" : {
"paths" : [
"/files/browse",
"/metrics/snapshot"
]
}
}
|
|--[no-]help| 输出帮助信息. (默认值: false)|
|--http_authenticators=VALUE| HTTP authenticator implementation to use when handling requests to authenticated endpoints. Use the default basic, or load an alternate HTTP authenticator module using --modules.
Currently there is no support for multiple HTTP authenticators. (default: basic)|
|--http_framework_authenticators=VALUE|HTTP authenticator implementation to use when authenticating HTTP frameworks. Use the basic authenticator or load an alternate HTTP authenticator module using --modules. This must be used in conjunction with --authenticate_http_frameworks.
Currently there is no support for multiple HTTP authenticators.|
|--ip=VALUE|监听的ip地址. 不能与--ip_discovery_command一起使用 . (master 默认: 5050; agent 默认: 5051)|
|--ip_discovery_command=VALUE|Optional IP discovery binary: if set, it is expected to emit the IP address which the master/agent will try to bind to. Cannot be used in conjunction with --ip.|
|--port=VALUE|Port to listen on.|
|--[no-]version|Show version and exit. (default: false)|
|--hooks=VALUE|A comma-separated list of hook modules to be installed inside master/agent.|
|--hostname=VALUE|The hostname the agent node should report, or that the master should advertise in ZooKeeper. If left unset, the hostname is resolved from the IP address that the master/agent binds to; unless the user explicitly prevents that, using --no-hostname_lookup, in which case the IP itself is used.|
|--[no-]hostname_lookup|Whether we should execute a lookup to find out the server"s hostname, if not explicitly set (via, e.g., --hostname). True by default; if set to false it will cause Mesos to use the IP address, unless the hostname is explicitly set. (default: true)|
|--modules=VALUE |List of modules to be loaded and be available to the internal subsystems.
Use --modules=filepath to specify the list of modules via a file containing a JSON-formatted string. filepath can be of the form file:///path/to/file or /path/to/file.
Use --modules="{...}" to specify the list of modules inline.
Example:
{
"libraries": [
{
"file": "/path/to/libfoo.so",
"modules": [
{
"name": "org_apache_mesos_bar",
"parameters": [
{
"key": "X",
"value": "Y"
}
]
},
{
"name": "org_apache_mesos_baz"
}
]
},
{
"name": "qux",
"modules": [
{
"name": "org_apache_mesos_norf"
}
]
}
]
