我已经在 Unix 服务器上安装了 Mongodb 和 PHP 驱动程序。
我的问题是,我怎么知道蒙戈德布是不是在逃跑?是否有一个简单的命令行查询来检查状态?如果我从 shell 启动它一次,如果我退出 shell,它会继续运行(这似乎不是这种情况)。如何使 Mongodb 连接持久化并在服务器重新启动时自动启动?
我可以跑:
-bash-3.2$ su

如果我打开一个单独的 shell,我就可以连接到 mongodb:
-bash-3.2$ cd /var/lib
-bash-3.2$ ./mongodb-linux-i686-1.6.5/bin/mongo
MongoDB shell version: 1.6.5
connecting to: test
> db.foo.find()
{ "_id" : ObjectId("4d63d7d3eb95985ab19c8feb"), "a" : 1 }
然而,如果关闭初始 shell,就无法连接:
-bash-3.2$ cd /var/lib
-bash-3.2$ ./mongodb-linux-i686-1.6.5/bin/mongo
MongoDB shell version: 1.6.5
connecting to: test
