hexo 支持多种部署方式, 如 git repos/rsync/Heroku/FTPSync等, 如果博客使用 github pages 托管, 那么用 git repos 的方式部署最方便了, 如果是自己的vps, rsync是一种不错的方式.

使用 hexo-deployer-rsync

配置, vim $SITE_HOME/_config.yml :

deploy:
  type: rsync
  host: <host>
  user: <user>
  root: <root>
  port: [port]
  delete: [true|false]
  verbose: [true|false]
  ignore_errors: [true|false]

执行 hexo generate 和 hexo deploy :

......

[ '--delete',
  '-v',
  '-az',
  '/home/niko/mount/hsb_ssd_1/niko/dev/code/git_repos/HexoBlog/hexo-hello/public/',
  '-e ssh',
  '--port=22222',
  'root@104.224.xxx.xxx:www.nikoai.pw/' ]

明明配置了非22的ssh端口, 但执行deploy时仍然连接22端口, 看了下代码 node_modules/hexo-deployer-rsync/lib/deployer.js, :

'use strict';

var chalk = require('chalk');
var spawn = require('hexo-util/lib/spawn');

module.exports = function(args) {
  if (!args.host || !args.user || !args.root) {
    var help = '';

    help += 'You should configure deployment settings in _config.yml first!\n\n';
    help += 'Example:\n';
    help += '  deploy:\n';
    help += '    type: rsync\n';
    help += '    host: <host>\n';
    help += '    user: <user>\n';
    help += '    root: <root>\n';
    help += '    port: [port] # Default is 22\n';
    help += '    delete: [true|false] # Default is true\n';
    help += '    args: <rsync args>\n';
    help += '    verbose: [true|false] # Default is true\n';
    help += '    ignore_errors: [true|false] # Default is false\n\n';
    help += 'For more help, you can check the docs: ' + chalk.underline('http://hexo.io/docs/deployment.html');

    console.log(help);
    return;
  }

  console.log("niko debug:");
  console.log(args);

  if (!args.hasOwnProperty('port')) args.port = 22;
  if (!args.hasOwnProperty('delete')) args.delete = true;
  if (!args.hasOwnProperty('verbose')) args.verbose = true;
  if (!args.hasOwnProperty('ignore_errors')) args.ignore_errors = false;

  var params = [
    '-az',
    this.public_dir,
    '-e ssh',
    args.user + '@' + args.host + ':' + args.root
  ];

  if (args.port && args.port > 0 && args.port < 65536) {
    params.splice(params.length - 1, 0, '--port=' + args.port);
  }

  if (args.verbose) params.unshift('-v');
  if (args.ignore_errors) params.unshift('--ignore-errors');
  if (args.delete) params.unshift('--delete');
  if (args.args) params.unshift(args.args);

  console.log(params);

  return spawn('rsync', params, {verbose: true});
};

好像发现了问题, 从上面代码可知, deployer 也是 spawn rsync 来进行发布的, hexo 配置里的参数和值会转换成rsync的. 但是指定port的代码有点问题, 需要做以下修改:

把

'-e ssh',

改成

"-e 'ssh -p " + args.port + "'",

写成一个sh脚本

上面的操作略为麻烦, 不用hexo的插件, 也可以写成一个shell文件, 下次直接执行即可:

vim deploy_to_vps.sh

#!/bin/sh
rsync -rvz -e 'ssh -p 22222' --progress -a ./public user@host:/data/hexo-blog
