Question

我需要帮助找到我最近升级时搞砸了什么。

在我的Ubuntu 14.04系统上，我最近清除了所有mongod-org

# apt-get purge mongod-org
# apt-get autoremove

然后通过Mongo的说明安装（获得新密钥添加了3.2源代码）

# apt-get update
# apt-get mongodb-org

一切似乎安装得很好。让我们开始吧：

# service mongod start
mongod start/running, process 18811
# ps -ef | grep 18811
#

换句话说，不开始。没有写到mongod.log所以让我们尝试命令行！

# mongod

啊，哈哈！没有/ data / db目录！但是，我有/etc/mongod.conf据说指向“/ var / lib / mongodb”。

这是/etc/mongod.conf

$ cat /etc/mongod.conf
storage:
  dbPath: "/var/lib/mongodb"
  engine: "wiredTiger"
  journal:
    enabled: true

systemLog:
  destination: file
  path: "/var/log/mongodb/mongod.log"
  logAppend: true

net:
  bindIp: 127.0.0.1
  port: 27017

所以，也许我的upstart配置不读取此配置文件，因为/ data / db是默认设置。但是，我的/etc/init/mongod.conf有一个可以读取/etc/mongod.conf的指令。

我的/etc/init/mongod.conf文件

# Ubuntu upstart file at /etc/init/mongod.conf

# Recommended ulimit values for mongod or mongos
# See http://docs.mongodb.org/manual/reference/ulimit/#recommended-settings
#
limit fsize unlimited unlimited
limit cpu unlimited unlimited
limit as unlimited unlimited
limit nofile 64000 64000
limit rss unlimited unlimited
limit nproc 64000 64000

kill timeout 300 # wait 300s between SIGTERM and SIGKILL.

pre-start script
  DAEMONUSER=${DAEMONUSER:-mongodb}
  if [ ! -d /var/lib/mongodb ]; then
    mkdir -p /var/lib/mongodb && chown mongodb:mongodb /var/lib/mongodb
  fi
  if [ ! -d /var/log/mongodb ]; then
    mkdir -p /var/log/mongodb && chown mongodb:mongodb /var/log/mongodb
  fi
  touch /var/run/mongodb.pid
  chown $DAEMONUSER /var/run/mongodb.pid
end script

start on runlevel [2345]
stop on runlevel [06]

script
  ENABLE_MONGOD="yes"
  CONF=/etc/mongod.conf
  DAEMON=/usr/bin/mongod
  DAEMONUSER=${DAEMONUSER:-mongodb}
  DAEMONGROUP=${DAEMONGROUP:-mongodb}

  if [ -f /etc/default/mongod ]; then . /etc/default/mongod; fi

  # Handle NUMA access to CPUs (SERVER-3574)
  # This verifies the existence of numactl as well as testing that the command works
  NUMACTL_ARGS="--interleave=all"
  if which numactl >/dev/null 2>/dev/null && numactl $NUMACTL_ARGS ls / >/dev/null 2>/dev/null
  then
    NUMACTL="$(which numactl) -- $NUMACTL_ARGS"
    DAEMON_OPTS=${DAEMON_OPTS:-"--config $CONF"}
  else
    NUMACTL=""
    DAEMON_OPTS="-- "${DAEMON_OPTS:-"--config $CONF"}
  fi

  if [ "x$ENABLE_MONGOD" = "xyes" ]
  then
    exec start-stop-daemon --start \
        --chuid $DAEMONUSER:$DAEMONGROUP \
        --pidfile /var/run/mongodb.pid \
        --make-pidfile \
        --exec $NUMACTL $DAEMON $DAEMON_OPTS --setParameter failIndexKeyTooLong=false
  fi
end script

所以，让我们尝试使用--config /etc/init.d从命令行启动mongod

# mongod --config /etc/mongod.conf

这很有效。但是，我需要通过暴发户来解决这个问题！有什么想法吗？

好的，所以我添加了一些日志记录到upstart脚本：

script
  exec 2>>/dev/.initramfs/mongo-init.log
  set -x
  ...

这提出了以下内容：

more /dev/.initramfs/mongo-init.log
+ ENABLE_MONGOD=yes
+ CONF=/etc/mongod.conf
+ DAEMON=/usr/bin/mongod
+ DAEMONUSER=mongodb
+ DAEMONGROUP=mongodb
+ [ -f /etc/default/mongod ]
+ . /etc/default/mongod
+ limit fsize unlimited unlimited
/proc/self/fd/9: 1: /etc/default/mongod: limit: not found

看看/ etc / default / mongod，我有：

more mongod
limit fsize unlimited unlimited  # (file size)
limit cpu unlimited unlimited    # (cpu time)
limit as unlimited unlimited     # (virtual memory size)
limit nofile 64000 64000         # (open files)
limit nproc 64000 64000          # (processes/threads)

这是尝试调整以前的版本，我猜不再支持了。我评论了所有的东西（不想把它扔掉），而现在的新贵也在工作。

希望这可以帮助其他有类似问题的人

Ubuntu 14.04上的MongoDB 3.2似乎没有读取/etc/mongod.conf
