mongodb的安装：

[root@gitlab ~]# cd /usr/local/
[root@gitlab local]# mkdir mongodb

在 mongodb目录下创建data目录和logs目录，以及日志文件mongodb.log的目录

[root@gitlab local]# cd mongodb/
[root@gitlab mongodb]# mkdir {data,logs}
[root@gitlab mongodb]# ls
data logs

[root@gitlab mongodb]# touch mongodb.log

将内容解压到mongodb目录下面：

tar -zxvf mongodb-linux-x86_64-rhel70-5.0.13.tgz -C /usr/local/mongodb

 /etc/profile添加mongodb的环境变量：

#mongodb
export Mongo_HOME=/usr/local/mongodb
export PATH=$Mongo_HOME/bin:$PATH

添加完，source生效配置文件

vi /etc/profile
[root@gitlab mongodb]# source /etc/profile

、添加 MongoDB 配置文件

1、编辑mongodb.conf文件

[root@gitlab mongodb]# cat /etc/mongodb.conf
#指定数据库路径
dbpath=/usr/local/mongodb/data
#指定mongodb的日志路径：
logpath=/usr/local/mongodb/logs/mongodb.log
#指定写日志为追加
logappend=true
#端口号
port=27017
#方便外网访问，写成所有网段
bind_ip=0.0.0.0
fork=true #以守护进程运行mongodb，创建mongodb进程
#auth=true #启用用户验证

[root@gitlab mongodb]#

启动和关闭 MongoDB

[root@gitlab bin]# mongod -f /etc/mongodb.conf
