我在运行的Digital Ocean服务器上有2个Ghost博客：

> Ubuntu 14.04.3 LTS
> Nginx 1.4.6(Ubuntu)
>节点v0.12.7

我使用instructions provided by Digital Ocean来设置博客,他们之前工作得很好并且幸存下来.

昨晚,我将博客#1从Ghost v0.6.0升级到0.7.0并没有遇到任何问题.升级之后,我运行了服务ghost- {blog1}重新启动,它在线与盛况和胜利.

我立即尝试按照相同的步骤升级博客#2,但是当我在重新启动服务后在浏览器中打开它时,我收到了“502 Bad Gateway”错误.

我发现npm无法正确安装sqlite3并修复了它.现在,我可以通过运行npm start –production成功启动博客.终端显示Ghost正在运行并拦截请求,我可以在浏览器中使用该站点和博客应用程序.

但是当我运行服务ghost- {blog2}启动时,它会继续失败而不会出现终端错误.我收到以下消息：

ghost-{blog2} start/running,process 1693

但我仍然在浏览器中看到“502 Bad Gateway”错误.

编辑：我更改了我的启动脚本以运行npm start –production> ghost- {blog2} .log而不是npm start –production,我可以看到Ghost启动,然后立即退出而没有错误：

> ghost@0.7.0 start /var/www/{blog2}/ghost
> node index

这就是日志中的所有内容,即使在几次点击页面之后也是如此. Nginx记录请求,但Ghost没有.

相比之下,当我通过运行npm start –production>启动博客时来自终端的ghost- {blog2} .log,日志继续如下：

> ghost@0.7.0 start /var/www/{blog2}/ghost
> node index

任何人都可以建议我可以采取的步骤来排除故障吗？

编辑：以下是每个博客的相关配置详细信息.

博客#1：这是有效的

/var/www/{blog1}/config.js

production: {
    url: 'http://{blog1}',mail: {},database: {
        client: 'sqlite3',connection: {
            filename: path.join(__dirname,'/content/data/ghost.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: '2369'
    }
},

在/ etc / Nginx的/启用的站点 – / {} blog1

    server {
        listen 80;

        server_name {blog1};

        root /usr/share/Nginx/html;
        index index.html index.htm;

        client_max_body_size 10G;

        location / {
            proxy_pass http://localhost:2369;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_buffering off;
        }
    }

/etc/init/ghost-{blog1}.conf

    # ghost-{blog1}

    start on startup

    script
        cd /var/www/{blog1}
        npm start --production
    end script

博客#2：当我开始使用npm start –production时,这个工作正常,但当我作为服务启动时失败

/var/www/{blog2}/ghost/config.js

production: {
    url: 'http://{blog2}',for iisnode set this to `process.env.PORT`
        port: '2777'
    }
},

在/ etc / Nginx的/启用的站点 – / {} blog2

    server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        server_name {blog2};

        root /usr/share/Nginx/html;
        index index.html index.htm;

        client_max_body_size 10G;

        location / {
            proxy_pass http://localhost:2777;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_buffering off;
        }
    }

/etc/init/ghost-{blog2}.conf

    # ghost-{blog2}

    start on startup

    script
        cd /var/www/{blog2}/ghost
        npm start --production > ghost-{blog2}.log
    end script
