CentOS 6.5下通过yum安装MongoDB记录

安装MongoDB

1、创建repo

vi /etc/yum.repos.d/mongodb-org-3.6.repo

1.  
   [mongodb-org-3.6]
2.  
   name=MongoDB Repository
3.  
   baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.6/x86_64/
4.  
   gpgcheck=0
5.  
   enabled=1

2、安装MongoDB和相关工具

sudo yum install -y mongodb-org

3、启动MongoDB

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：

1.  
   # sudo service mongod status
2.  
   Redirecting to /bin/systemctl status mongod.service
3.  
   ● mongod.service - High-performance, schema-free document-oriented database
4.  
   Loaded: loaded (/usr/lib/systemd/system/mongod.service; disabled; vendor preset: disabled)
5.  
   Active: active (running) since 一 2016-09-12 09:50:16 CST; 15s ago
6.  
   Process: 8787 ExecStart=/usr/bin/mongod $OPTIONS run (code=exited, status=0/SUCCESS)
7.  
   Main PID: 8842 (mongod)
8.  
   CGroup: /system.slice/mongod.service
9.  
   └─8842 /usr/bin/mongod --quiet -f /etc/mongod.conf run
10.  
     
11.  
    9月 12 09:50:13 192.168.1.155 systemd[1]: Starting High-performance, schema-free document-oriented database...
12.  
    9月 12 09:50:14 192.168.1.155 mongod[8787]: about to fork child process, waiting until server is ready for connections.
13.  
    9月 12 09:50:14 192.168.1.155 mongod[8787]: forked process: 8842
14.  
    9月 12 09:50:16 192.168.1.155 mongod[8787]: child process started successfully, parent exiting
15.  
    9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：

1.  
   # sudo service mongod status
2.  
   Redirecting to /bin/systemctl status mongod.service
3.  
   ● mongod.service - High-performance, schema-free document-oriented database
4.  
   Loaded: loaded (/usr/lib/systemd/system/mongod.service; disabled; vendor preset: disabled)
5.  
   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

进入Mongo命令行

1.  
   # mongo
2.  
   MongoDB shell version: 2.6.12
3.  
   connecting to: test
4.  
   Welcome to the MongoDB shell.
5.  
   For interactive help, type "help".
6.

9.

10.  
    Server has startup warnings:
11.  
    2016-09-12T09:50:14.195+0800 [initandlisten]
12.

Linux下安装PHP的MongoDB扩展

因为是手动安装的MongoDB，所以也需要编译安装MongoDB扩展，步骤如下：
1)下载最新的PHP mongodb扩展源码，源码可以在http://pecl.php.net/package/mongo下载.

2）解压,进入安装目录

1.  
   wget http://pecl.php.net/get/mongo-1.4.0.tgz
2.  
   tar -zxvf mongo-1.4.0.tgz
3.  
   cd mongo-1.4.0

3)进入文件夹后，首先运行phpize来编译扩展的环境
/usr/bin/phpize

1.  
   PHP Api Version: 20121113
2.  
   Zend Module Api No: 20121212
3.  
   Zend Extension Api No: 220121212

4)运行后，我们运行./configure脚本来进行配置
`
./configure --with-php-config=/usr/local/php/bin/php-config && make && make install

--with-php-config 这个参数是告诉配置脚本 php-config 这个程序的路径

5)完成后，请编辑你[php](http://lib.csdn.net/base/php).ini文件增加一行extension=mongo.so`

一般默认的编译php的ini文件/usr/local/php/etc/php.ini重启Apache/Nginx[或者/etc/init.d/php-fpm restart] 打开 phpinfo看到mongo模块，证明mongodb的php扩展安装成功。
OK ,至此你可以使用php来操作 MongoDB 了

----------------------------------

mongo设置密码 重启服务 重新登录
mongo
show dbs;
use admin
db.createUser({user:"admin", pwd:"111111", roles: [{role: "root", db:"admin"}]})

service mongod restart

mongo -u admin -p 111111 127.0.0.1:27017/admin
