mongodb 安装升级的各种错误解决

更新

sudo apt-get upgrade mongodb-org*

ubuntu 14 升级 16 后

报错：Failed to start mongod.service: Unit mongod.service not found

sudo systemctl unmask mongodb

sudo service mongod start

# 可以通过日志来查看状态
cat /var/log/mongodb/mongod.log

安装

创建列表文件，官方ubuntu16.04安装代码如下：

echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

执行 sudo apt-get update 后报错

Some index files failed to download. They have been ignored, or old ones used instead.

解决办法，将镜像地址改为阿里云的：

echo "deb http://mirrors.aliyun.com/mongodb/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
