Mongodb-简单部署

一、MongoDB是一款NoSql数据库

二、部署单实例MongoDB

1.安装环境：

（1）系统：Centos7.2

（2）MongoDB：Percona的MongoDB3.4

2.配置yum源

percona官方文档【https://www.percona.com/doc/percona-repo-config/yum-repo.html】

# yum -y install http://www.percona.com/downloads/percona-release/redhat/0.1-4/percona-release-0.1-4.noarch.rpm

3.yum安装MongoDB

percona官网文档【https://www.percona.com/doc/percona-server-for-mongodb/3.6/install/yum.html#yum】

# yum install Percona-Server-MongoDB-

4.创建MongoDB服务目录

# mkdir -p /opt/mongo/{mongo_data,mongo_log}
# chown -R mongod.mongod /opt/mongo/
# usermod -d /opt/mongo mongod

5.优化配置文件

# vim /etc/mongod.conf
修改以下标红部分配置

storage:
    dbPath: /opt/mongo/mongo_data/

systemLog:
  destination: file
  logAppend: true
  path: /opt/mongo/mongo_log/mongod.log

net:
    port: 27017
    bindIp: 本机内网IP

6.修改systemd相关配置

# vim /usr/lib/systemd/system/mongod.service
修改
PIDFile=/opt/mongo/mongo_log/mongod.pid

# vim /etc/sysconfig/mongod
STDOUT="/opt/mongo/mongo_log/mongod.stdout"
STDERR="/opt/mongo/mongo_log/mongod.stderr"

# systemctl daemon-reload

7.启动MongoDB实例

# systemctl enable mongod　　#开机自启
# systemctl start mongod　　 #启动MongoDB

8.登录MongoDB

# mongo --host 10.140.0.4 --port
