让 Ghost 使用 MySQL 数据库

Ghost 默认使用 sqlite3 数据库,对于一般使用足够了,但是内容多的话,就会拖慢整个系统,也就影响页面打开速度了,现在就来说说怎么配置 MySQL 数据库吧。

Ghost 安装目录下面有一个配置文件例子 -- config.example.js,我们复制一份这个文件,并修改名称为 config.js。

在生产环境下 Ghost 系统会加载 production 段的配置信息,因此,把 MySQL 的配置信息写到这一段就行。代码如下:

// # Ghost Configuration
// Setup your Ghost install for various environments

var path = require('path'),  
    config;

config = {  
    // ### Development **(default)**
    development: {
        // The url to use when providing links to the site, E.g. in RSS and email.
        url: 'http://my-ghost-blog.com',

        // Example mail config
        // Visit http://docs.ghost.org/mail for instructions
        // ```
        //  mail: {
        //      transport: 'SMTP',
        //      options: {
        //          service: 'Mailgun',
        //          auth: {
        //              user: '', // mailgun username
        //              pass: ''  // mailgun password
        //          }
        //      }
        //  },
        // ```

        database: {
            client: 'sqlite3',
            connection: {
                filename: path.join(__dirname, '/content/data/ghost-dev.db')
            },
            debug: false
        },
        server: {
            // Host to be passed to node's `net.Server#listen()`
            host: '127.0.0.1',
            // Port to be passed to node's `net.Server#listen()`, for iisnode set this to `process.env.PORT`
            port: '2368'
        }
    },

    // ### Production  修改为使用 MySQL 数据库
    // When running Ghost in the wild, use the production environment
    // Configure your URL and mail settings here
    production: {
        url: 'http://my-ghost-blog.com',
        mail: {},
        database: {
            client: 'mysql',
            connection: {
                host     : '127.0.0.1',
                user     : 'username', //用户名
                password : '', //密码
                database : 'ghost', //数据库名
                charset  : 'utf8'
            }
        },
        server: {
            // Host to be passed to node's `net.Server#listen()`
            host: '127.0.0.1',
            // Port to be passed to node's `net.Server#listen()`, for iisnode set this to `process.env.PORT`
            port: '2368'
        }
    },

    // **Developers only need to edit below here**

    // ### Testing
    // Used when developing Ghost to run tests and check the health of Ghost
    // Uses a different port number
    testing: {
        url: 'http://127.0.0.1:2369',
        database: {
            client: 'sqlite3',
            connection: {
                filename: path.join(__dirname, '/content/data/ghost-test.db')
            }
        },
        server: {
            host: '127.0.0.1',
            port: '2369'
        }
    },

    // ### Travis
    // Automated testing run through GitHub
    'travis-sqlite3': {
        url: 'http://127.0.0.1:2369',
        database: {

            connection: {
                filename: path.join(__dirname, '/content/data/ghost-travis.db')
            }
        },
        server: {
            host: '127.0.0.1',
            port: '2369'
        }
    },

    // ### Travis
    // Automated testing run through GitHub
    'travis-mysql': {
        url: 'http://127.0.0.1:2369',
        database: {
            client: 'mysql',
            connection: {
                host     : '127.0.0.1',
                user     : 'travis',
                password : '',
                database : 'ghost_travis',
                charset  : 'utf8'
            }
        },
        server: {
            host: '127.0.0.1',
            port: '2369'
        }
    },

    // ### Travis
    // Automated testing run through GitHub
    'travis-pg': {
        url: 'http://127.0.0.1:2369',
        database: {
            client: 'pg',
            connection: {
                host     : '127.0.0.1',
                user     : 'postgres',
                password : '',
                database : 'ghost_travis',
                charset  : 'utf8'
            }
        },
        server: {
            host: '127.0.0.1',
            port: '2369'
        }
    }
};

// Export config
module.exports = config;
