CentOS 6.5下通过yum安装MongoDB记录

最近想尝试一下英特尔的基于WebRTC协同通信开发套件，其中的CS_WebRTC_Conference_Server_MCU依赖MongoDB。

MongoDB是什么？

MongoDB 是一个基于分布式文件存储的数据库。由 C++ 语言编写。旨在为 WEB 应用提供可扩展的高性能数据存储解决方案。

MongoDB 是一个介于关系数据库和非关系数据库之间的产品，是非关系数据库当中功能最丰富，最像关系数据库的。

安装MongoDB

参考：https://docs.mongodb.org/getting-started/shell/tutorial/install-mongodb-on-red-hat/

https://docs.mongodb.org/getting-started/shell/tutorial/install-on-linux/

1、创建repo

vi /etc/yum.repos.d/mongodb-org-3.2.repo

[mongodb-org-3.2]name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.2/x86_64/
gpgcheck=0
enabled=1

2、安装MongoDB和相关工具

sudo yum install -y mongodb-org

3、启动MongoDB

sudo service mongod start

4、验证MongoDB是否启动成功

cat /var/log/mongodb/mongod.log

查看是否有一句：[initandlisten] waiting for connections on port <port>

其中<port>是在/etc/mongod.conf中配置的，默认情况下是27017端口。

还有另一种方式：

# sudo service mongod statusRedirecting to /bin/systemctl status  mongod.service● mongod.service - High-performance, schema-free document-oriented database   Loaded: loaded (/usr/lib/systemd/system/mongod.service; disabled; vendor preset: disabled)   Active: active (running) since 一 2016-09-12 09:50:16 CST; 15s ago  Process: 8787 ExecStart=/usr/bin/mongod $OPTIONS run (code=exited, status=0/SUCCESS) Main PID: 8842 (mongod)   CGroup: /system.slice/mongod.service           └─8842 /usr/bin/mongod --quiet -f /etc/mongod.conf run9月 12 09:50:13 192.168.1.155 systemd[1]: Starting High-performance, schema-free document-oriented database...9月 12 09:50:14 192.168.1.155 mongod[8787]: about to fork child process, waiting until server is ready for connections.9月 12 09:50:14 192.168.1.155 mongod[8787]: forked process: 88429月 12 09:50:16 192.168.1.155 mongod[8787]: child process started successfully, parent exiting9月 12 09:50:16 192.168.1.155 systemd[1]: Started High-performance, schema-free document-oriented database.

会看到“Active: active (running)”，说明正在运行。

没有运行的情况：

# sudo service mongod statusRedirecting to /bin/systemctl status  mongod.service● mongod.service - High-performance, schema-free document-oriented database   Loaded: loaded (/usr/lib/systemd/system/mongod.service; disabled; vendor preset: disabled)   Active: inactive (dead)

Active: inactive (dead)

5、使MongoDB开机自动启动

sudo chkconfig mongod on

6、停止MongoDB

sudo service mongod stop

7、重启MongoDB

sudo service mongod restart

服务器配置: /etc/mongod.conf

# mongo.conf     #where to log   logpath=/var/log/mongo/mongod.log     logappend=true #以追加方式写入日志     # fork and run in background   fork = true    #port = 27017 #端口     dbpath=/var/lib/mongo #数据库文件保存位置   directoryperdb=true# Enables periodic logging of CPU utilization and I/O wait   #启用定期记录CPU利用率和 I/O 等待   #cpu = true    # Turn on/off security.

进入Mongo命令行

小结

通过yum安装是非常简单方便的，

不需要纠结依赖项的问题。
