无法在AWS Ubuntu上运行Mongod作为服务

Question

我在Linux上部署Mongo时遇到了问题，在AWS上运行。

vim /etc/yum.repos.d/mongodb-org-3.0.repo
sudo yum install -y mongodb-org
Error: Package: mongodb-org-tools-3.0.12-1.amzn1.x86_64 (Mongodb-org-3.0)
       Requires: libgcc_s.so.1(GCC_3.0)(64bit)
Error: Package: mongodb-org-mongos-3.0.12-1.amzn1.x86_64 (Mongodb-org-3.0)
       Requires: /bin/bash
Error: Package: mongodb-org-server-3.0.12-1.amzn1.x86_64 (Mongodb-org-3.0)
       Requires: openssl

因此，我使用

下载了MongoDB和UNTAR的TAR文件

tar -xvzf mongodb-linux-x86_64-amazon-3.2.7.tgz 

当我进入bin目录并使用mongod或mongo命令时，它起作用，但是尝试用作服务时，它会产生错误。

    cd mongodb-linux-x86_64-amazon-3.2.7/bin
    root@ip-172-31-43-40:/mongodb-linux-x86_64-amazon-3.2.7/bin# service mongod start

无法运行Mongod作为服务...因此，想知道启动守护程序所需的步骤，并保持连续运行（如服务）

Answer 1

看起来好像PID文件夹和文件权限不适用于默认守护程序。

最简单的解决方案是通过将＃放在配置文件中的行前方来禁用PID文件。

vi /etc/mongod.conf

找到pidfilepath =/var/run/mongodb/mongod.pid的行，并相应地更改。

# pidfilepath=/var/run/mongodb/mongod.pid
