Ubuntu16.04安装mongodb

1.导入软件源的公钥

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927

2.为mongodb创建软件源list文件
ubuntu12.04

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

ubuntu14.04

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

ubuntu16.04

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

3.更新软件源并安装mongodb

sudo apt-get update
sudo apt-get install -y mongodb-org

如果想要安装特定的版本，使用下面命令：

sudo apt-get install -y mongodb-org=3.2.9 mongodb-org-server=3.2.9 mongodb-org-shell=3.2.9 mongodb-org-mongos=3.2.9 mongodb-org-tools=3.2.9

4.配置启动文件
如果是ubuntu16.04的版本，需要手动新建/lib/systemd/system/mongod.service文件，并写入下面内容：

[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
Documentation=https://docs.mongodb.org/manual

[Service]
User=mongodb
Group=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf

[Install]
WantedBy=multi-user.target

sudo service mongod start
sudo service mongod restart
sudo service mongod stop

6.mongodb的完全卸载
先停止运行mongodb

sudo service mongod stop

再卸载软件

sudo apt-get purge mongodb-org*

删除数据库和日志文件

sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb

7.添加php的mongodb扩展

# pecl install mongodb
# echo "extension=mongodb.so" >> `php --ini | grep "Loaded Configuration" | sed -e "s|.*:\s*||"`
