Intro

之前blog所使用的是0.5.7的Ghost，最近又时间就顺手升级了下。

根据官方文档先升级到了0.7.1版本。

本来想先在本地测试的，结果估计是Mac node版本过高无法成功安装所需的node模块，一咬牙直接服务端升级，居然成功了，此刻就是ghost 0.7.1版本。

随后在0.7.1版本上升级到了最新版本(写此文时是0.9.0)。

值得注意的是替换完文件，npm install --production之后最好来一次nam start --production这个时候Ghost会做些版本升级。

七牛插件

还是使用了之前0.5.7版的七牛插件：

nam install qiniu --production

在config.js文件

config = {
    production: {
        storage: {  
           provider: 'qiniu',
           bucketname: 'xxx',
           ACCESS_KEY: 'xxx',
           SECRET_KEY: 'xxx',
           root: 'xxx',
           prefix: 'xxx'
        }
    }
}

替换core/server/storage/index.js文件为：

var errors  = require('../errors'),
    storage = {};

var config  = require('../config');

function getStorage(storageChoice) {
    // TODO: this is where the check for storage apps should go
    // Local file system is the default.  Fow now that is all we support.
    // storageChoice = 'local-file-store';
    storageChoice = (config.storage && config.storage.provider) || 'local-file-store';  

    if (storage[storageChoice]) {
        return storage[storageChoice];
    }

    try {
        // TODO: determine if storage has all the necessary methods.
        storage[storageChoice] = require('./' + storageChoice);
    } catch (e) {
        errors.logError(e);
    }

    // Instantiate and cache the storage module instance.
    storage[storageChoice] = new storage[storageChoice]();

    return storage[storageChoice];
}

module.exports.getStorage = getStorage;

在core/server/storage/目录下增加qiniu.js文件

// Qiniu CDN support

var _       = require('lodash'),
    express = require('express'),
    fs      = require('fs-extra'),
    path    = require('path'),
    util    = require('util'),
    utils   = require('../utils'),
    Promise = require('bluebird'),
    config = require('../config'),
    errors  = require('../errors'),
    baseStore   = require('./base'),
    crypto = require('crypto'),

    qiniu        = require('qiniu'),
    qiniuConfig  = config.storage,
    
    qiniuStore;

    qiniu.conf.ACCESS_KEY = qiniuConfig.ACCESS_KEY;
    qiniu.conf.SECRET_KEY = qiniuConfig.SECRET_KEY;
    qiniu.conf.USER_AGENT = 'Ghost ' + config.ghostVersion;

var putPolicy = new qiniu.rs.PutPolicy(qiniuConfig.bucketname);

function QiniuStore () {
}

util.inherits(QiniuStore, baseStore);

QiniuStore.prototype.save = function (image) {
    var uptoken = putPolicy.token();
    var md5sum = crypto.createHash('md5'),
        ext = path.extname(image.name),
        targetDirRoot = qiniuConfig.root,
        targetFilename,
        key,
        extra = new qiniu.io.PutExtra();

    var savedpath = path.join(config.paths.imagesPath, image.name);

    return Promise.promisify(fs.copy)(image.path, savedpath).then(function(){
        return Promise.promisify(fs.readFile)(savedpath);
    }).then(function(data){
        md5 = md5sum.update(data).digest('hex');

        targetFilename = path.join(targetDirRoot, md5.replace(/^(\w{1})(\w{2})(\w+)$/, '$1/$2/$3')) + ext;
        targetFilename = targetFilename.replace(/\\/g, '/');
        key = targetFilename.replace(/^\//, '');

        return Promise.promisify(qiniu.io.put)(uptoken, key, data, extra);
    }).then(function() {
        // Remove temp file
        return Promise.promisify(fs.unlink)(savedpath);
    }).then(function () {
        // prefix + targetFilename
        var fullUrl = qiniuConfig.prefix + targetFilename;
        return fullUrl;
    }).catch(function (e) {
        errors.logError(e);
        return Promise.reject(e);
    });
};

QiniuStore.prototype.exists = function (filename) {
    return new Promise(function (resolve) {
        fs.exists(filename, function (exists) {
            resolve(exists);
        });
    });
};

QiniuStore.prototype.serve = function (){
    // For some reason send divides the max age number by 1000
    return express['static'](config.paths.imagesPath, {maxAge: utils.ONE_YEAR_MS});
};

module.exports = QiniuStore;

Disqus,统计代码安装

最后自然不要遗漏了，disqus，和统计代码的安装😄，可以参考我之前从wordpress迁移的文章
