Centos 7 下Mongo4.0安装

YUM 安装Mongo(官方推荐)

1. 配置Yum 源

   ---

   cat > /etc/yum.repos.d/mongodb-org-4.0.repo << EOF
   [mongodb-org-4.0]
   name=MongoDB Repository
   baseurl=https://repo.mongodb.org/yum/redhat/7/mongodb-org/4.0/x86_64/
   gpgcheck=1
   enabled=1
   gpgkey=https://www.mongodb.org/static/pgp/server-4.0.asc
   EOF

2. 安装mongo包

   ---

   yum install mongodb-org

3. 启动mongo

   ---

   /sbin/service mongod start

4. 连接mongo

   ---

   mongo

5. 进入admin数据库

   ---

   use admin

6. 创建root账户

   ---

   db.createUser(
     {
       user: "root",
       pwd: "root",
       roles: [ { role: "root", db: "admin" } ]
     }
   )

7. 编辑mongo 配置文件(改变默认数据目录，添加安全认证，允许所有IP访问)

   ---

   vim /etc/mongod.conf

   storage:
     dbPath: /var/lib/mongo

   security:
     authorization: enabled

   net:
     port: 27017
     bindIp: 0.0.0.0

8. 禁止Centos selinux(重要！否则数据目录改变不成功，需要重启Centos)

   ---

   vim /etc/sysconfig/selinux
   SELINUX=disabled

9. selinux临时禁止(不需要重启Centos)

   ---

   setenforce 0

10. 重启mongo

    ---

    /sbin/service mongod restart

11. 测试连接

    ---

    mongo --port 27017 -u "root" -p "root" --authenticationDatabase "admin"
