网速较慢, 比较耗时, 推荐tar包安装, 下载地址

禁用SELinux

[root@paascloud-mongo-001 ~]# vi /etc/selinux/config
SELINUX=disabled

启动MongoDB

## 检查 mongodb 是否允许系统启动
systemctl is-enabled mongodb

## 使 mongodb 系统启动
systemctl enable mongodb

## 启动
systemctl start mongodb

## 查看启动状态
systemctl status mongodb 

## 停止
systemctl stop mongodb

验证MongoDB已经成功启动

设置开机启动

[root@paascloud-mongo-001 ~]# systemctl enable mongod.service

卸载MongoDB社区版

Stop MongoDB

[root@paascloud-mongo-001 ~]# systemctl stop mongod.service

Remove Packages

[root@paascloud-mongo-001 ~]# yum erase $(rpm -qa | grep mongodb-org)

Remove Data Directories

[root@paascloud-mongo-001 ~]# rm -r /var/log/mongodb
[root@paascloud-mongo-001 ~]# rm -r /var/lib/mongo

配置mongodb

开启远程访问

vim /etc/mongod.conf

#  bindIp: 127.0.0.1  # Listen to local interface only, comment to listen on all interfaces.

创建用户

[root@paascloud-mongo-001 bin]# mongo localhost/admin

> use admin
switched to db admin
> db.createUser(
  {
    user: "admin",
    pwd: "paascloud",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
  }
)

v2.6 docker 配置用户信息

公司使用的是2.6,默认只有admin用户admin库权限

# docker exec -it mongodb27017 /bin/bash
# cd bin
# mongo --port 27017 -u "admin" -p "password" --authenticationDatabase "admin"
> use tfc_db
> show users
> show roles
> db.addUser('tfc','password')
> db.auth('tfc','password')
> show collections
> db.createUser(
  {
    user: "xescm-dev",
    pwd: "paascloud",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
  }
)

db.grantRolesToUser(
    "xescm-dev",
    [
      { role: "readWriteAnyDatabase", db: "admin" }
    ]
)
