Question

我正在尝试使用mongodb设置Elastic Beanstalk。我从这个link得到了一个解决方案。但这对我不起作用。我正在使用＆＃34; 64位Amazon Linux 2014.03 v1.0.4。＆＃34;。当我尝试使用链接解决方案安装mongodb时，它会因以下错误而停止实例。

Error: failed to connect to [localhost:27017]

at process._tickCallback (node.js:415:13)

我按照说明将内容放在aws.config文件中。请帮忙。

我必须这么做才能创建一个gist所以我可以快速再做一次。

首先，ssh进入您的AWS EC2实例（ssh -i ec2-user @）

从现在开始，它几乎可以复制/粘贴：

echo "[MongoDB]
name=MongoDB Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
gpgcheck=0
enabled=1" | sudo tee -a /etc/yum.repos.d/mongodb.repo

sudo yum install -y mongodb-org-server mongodb-org-shell mongodb-org-tools

sudo mkdir /data /log /journal

//Mount partitions -- Find available ones for /data /log /journal
sudo mkfs.ext4 /dev/xvdf
sudo mkfs.ext4 /dev/xvdg
sudo mkfs.ext4 /dev/xvdh

echo '/dev/xvdf /data ext4 defaults,auto,noatime,noexec 0 0
/dev/xvdg /journal ext4 defaults,auto,noatime,noexec 0 0
/dev/xvdh /log ext4 defaults,auto,noatime,noexec 0 0' | sudo tee -a /etc/fstab

sudo mount /data
sudo mount /journal
sudo mount /log

sudo chown mongod:mongod /data /journal /log

sudo ln -s /journal /data/journal

nano /etc/mongod.conf
//Change to 
dbpath = /data
logpath = /log/mongod.log

sudo nano /etc/security/limits.conf

现在填写文件内容：

* soft nofile 64000
* hard nofile 64000
* soft nproc 32000
* hard nproc 32000

现在更改此文件：

sudo nano /etc/security/limits.d/90-nproc.conf

内容：

* soft nproc 32000
* hard nproc 32000

sudo blockdev --setra 32 /dev/xvdf

echo 'ACTION=="add", KERNEL=="xvdf", ATTR{bdi/read_ahead_kb}="16"' | sudo tee -a /etc/udev/rules.d/85-ebs.rules

并且不要忘记启动守护进程：

//Run persistent
mongod --fork --logpath /var/log/mongodb/mongod.log

如何在Elastic Beanstalk中安装mongodb？
