Note：安装完成会自动创建mongod用户和mongod服务

创建目录

mkdir -p /mongodb/data
mkdir -p /mongodb/log
chown mongod.mongod -R /mongodb

修改参数文件

[root@fwl-node01 mongodb]# vi /etc/mongod.conf

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /mongodb/log/mongod.log

# Where and how to store data.
storage:
  dbPath: /mongodb/data
  journal:
    enabled: true
#  engine:
#  mmapv1:
#  wiredTiger:

Note：自定义数据目录和日志目录

启动服务

[root@fwl-node01 mongodb]# systemctl start mongod


查看日志
[root@fwl-node01 mongodb]# tail -f /mongodb/log/mongod.log
