# 如何在一台主机同时运行多个GitBook

参考 [How to change default listening port when use gitbook to serve a site?](https://github.com/GitbookIO/gitbook/issues/622)

```
gitbook --port 3000 serve
```

但是，这个方法启动第二个服务时（例如指定端口 `--port 3001` ）依然会遇到报错

```
... Uhoh. Got error listen EADDRINUSE :::35729 ...
Error: listen EADDRINUSE :::35729
    at Object.exports._errnoException (util.js:874:11)
    at exports._exceptionWithHostPort (util.js:897:20)
    at Server._listen2 (net.js:1234:14)
    at listen (net.js:1270:10)
    at Server.listen (net.js:1366:5)
    at Server.listen (/Users/huatai/.gitbook/versions/2.6.5/node_modules/tiny-lr/lib/server.js:164:15)
    at Promise.apply (/Users/huatai/.gitbook/versions/2.6.5/node_modules/q/q.js:1078:26)
    at Promise.promise.promiseDispatch (/Users/huatai/.gitbook/versions/2.6.5/node_modules/q/q.js:741:41)
    at /Users/huatai/.gitbook/versions/2.6.5/node_modules/q/q.js:1304:14
    at flush (/Users/huatai/.gitbook/versions/2.6.5/node_modules/q/q.js:108:17)

You already have a server listening on 35729
You should stop it and try again.
```

使用 `lsof | grep 35729` 可以看到

```
tcp46      0      0  *.35729                *.*                    LISTEN
```

参考 [can not run multi gitbook server in one machine](https://github.com/GitbookIO/gitbook/issues/745) 原来 gitbook 还有一个 `lrport` 参数（动态重新加载服务端口），这个参数

```
serve [book] Build then serve a gitbook from a directory
--port Port for server to listen on (Default is 4000)
--lrport Port for livereload server to listen on (Default is 35729)
--watch Enable/disable file watcher (Default is true)
--format Format to build to (Default is website; Values are website, json, ebook)
--log Minimum log level to display (Default is info; Values are debug, info, warn, error, disabled)
```

所以第一个服务启动可以使用默认参数（`port 4000`和`lrport 35729`）

```
gitbook serve
```

第二个服务启动应该使用

```
gitbook --port 4001 --lrport 35730 serve
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://huataihuang.gitbook.io/cloud-atlas-draft/develop/doc/gitbook/run_multi_gitbook_in_one_host.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
