centos7 安装mongodb

Yum 安装

vi /etc/yum.repos.d/mongodb-org-6.0.repo

填充内容如下：

[mongodb-org-6.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc

sudo yum install -y mongodb-org

用这个命令可以指定版本:

sudo yum install -y mongodb-org-6.0.2 mongodb-org-database-6.0.2 mongodb-org-server-6.0.2 mongodb-mongosh-6.0.2 mongodb-org-mongos-6.0.2 mongodb-org-tools-6.0.2

vi /etc/mongod.conf

修改

# where to write logging data.
systemLog:destination: filelogAppend: truepath: /var/log/mongodb/mongod.log# Where and how to store data.
storage:dbPath: /var/lib/mongojournal:enabled: true
#  engine:

net:port: 2007bindIp: 0.0.0.0  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.

启动:

systemctl start mongod

遇到问题：

journalctl -xe

查看日志 vi /var/log/mongodb/mongod.log，得到：

{"t": {"$date": "2022-10-10T06:36:19.084-04:00"},"s": "E","c": "CONTROL","id": 20568,"ctx": "initandlisten","msg": "Error setting up listener","attr": {"error": {"code": 9001,"codeName": "SocketException","errmsg": "Permission denied"}}
}

解决方案：

用命令 mongod -f /etc/mongod.conf --nounixsocket --fork 启动

不用 systemctl start

附： nounixsocket：套接字文件，默认为false ，意为生成socket文件。可在 conf 中配置当设置为true时，不会生成socket文件。 nounixsocket = false
