ubuntu 15.04上的mongodb 3必须在每次重启后手动启动mongod服务

我曾经有mongodb 2.6.3，mongod服务一直在工作。昨天我更新到mongodb 3.0.3，如果我在终端中键入

mongo

，我会得到以下信息：

2015-06-06T10:24:51.679+0200 W NETWORK  Failed to connect to     127.0.0.1:27017, reason: errno:111 Connection refused
2015-06-06T10:24:51.682+0200 E QUERY    Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed
    at connect (src/mongo/shell/mongo.js:179:14)
    at (connect):1:6 at src/mongo/shell/mongo.js:179
exception: connect failed

每次重新启动后，我都必须启动

服务。有办法解决这个问题吗

p.S.我被要求提供
initctl list
的输出，如下所示：

您的mongodb服务器未配置为自动启动

在使用systemd的ubuntu上，您必须使用：
systemctl启用mongodb

是否有一些官方文档
Con您向我们展示了
initctl列表的输出
？
initctl:href\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\，但Upstart作业不支持lsb标头。insserv:警告：脚本“binfmt支持”缺少LSB标记并覆盖insserv:默认启动未定义，假设脚本的启动运行级别为空
binfmt支持“insserv:默认停止未定义，假设停止运行级别为空”对于脚本
binfmt支持'
Try
systemctl后台程序重新加载
sudorm/etc/init.d/mongodb
。当我运行
update rc.d mongodb defaults
之后，我得到
update rc.d:错误：initscript不存在：/etc/init.d/mongodb
，现在：
systemctl enable mongodb
无法执行操作：不支持操作
