Linux环境下搭建MongoDB

MongoDB企业版官方下载地址，下载版本：

使用远程工具登录Linux系统后， 将Mongodb压缩文件上传到/usr/local目录下解压缩

cd /usr/local
tar -zxvf 压缩包名称

将解压好的mongodb文件名修改为mongodb-server【看个人喜好，可以不做修改】

mv 原文件名 mongodb-server

在mongodb-server目录下为mongodb配置数据库保存的目录、日志保存的目录以及配置文件

cd /usr/local/mongodb-server
mkdir data #数据库保存的目录
mkdir logs #日志保存的目录
mkdir etc/mongodb.conf #启动配置文件

或

cd /usr/local/mongodb-server
mkdir data logs etc/mongodb.conf

编辑配置文件

vim /usr/local/etc/mongodb.conf

配置文件内容

dbpath=/usr/local/mongodb-server/data #数据库保存的目录，后续创建的数据库和数据表都会保存在该目录下
logpath=/usr/local/mongodb-server/logs/mongodb.log #日志文件保存目录，mongodb.log文件无需自己创建，mongodb会为我们自动生成
port=27017 #指定端口
fork=true #启动后，开启后台运行
journal=false
bind_ip=0.0.0.0 #允许外网访问【记得防火墙打开端口】
auth=false #不使用身份认证进行登录，默认使用root权限

启动mongodb

cd /usr/local/mongodb-server
./mongod -f /usr/local/mongodb-server/etc/mongodb.conf

启动成功反馈

child process started successfully, parent exiting

进入mongodb客户端

cd /usr/local/mongodb-server
./mongo

进入成功界面

开放端口

# 查看防火墙状态 
systemctl status firewalld
# 开启防火墙 
systemctl start firewalld  
# 关闭防火墙 
systemctl stop firewalld
# 开启防火墙 
service firewalld start 
# 若遇到无法开启
先用：systemctl unmask firewalld.service 
然后：systemctl start firewalld.service

# 添加指定需要开放的端口：
firewall-cmd --add-port = 端口号/tcp --permanent
# 重载入添加的端口：
firewall-cmd --reload
# 查询指定端口是否开启成功，如果端口已开启，返回yes：
firewall-cmd --query-port = 端口号/tcp
# 移除指定端口：
firewall-cmd --permanent --remove-port=123/tcp
