Centos6.5下搭建Mongodb服务

[root@test2 ~]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m

[root@test2 ~]# cd /usr/local/cd /usr/local/
[root@test2 ~]# cd /usr/local/wget  https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.0.7.tgz[/code] href="https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel62-3.0.7.tgz" target=_blank>

3.解压并创建数据库的存储及日志目录：

[root@test2 local]# tar -zxvf mongodb-linux-x86_64-rhel62-3.0.7.tgz
[root@test2 local]# mkdir -p mogodb/{data,logs}
[root@test2 local]# cd mogodb/
[root@test2 mogodb]# ls
bin  data  GNU-AGPL-3.0  logs  README  THIRD-PARTY-NOTICES
[root@test2 mogodb]# cd logs/
[root@test2 logs]# touch mongodb.log
4.建立配置文件

[root@test2 mogodb]# vi /usr/local/mongodb/bin/mongodb.conf
dbpath=/usr/local/mongodb/data
logpath=/usr/local/mongodb/logs/mongodb.log
port=27017
fork=true
nohttpinterface=true


5.启动MongoDB

[root@test2 mongodb]# /usr/local/mongodb/bin/mongod --bind_ip localhost -f /usr/local/mongodb/bin/mongodb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 1449
child process started successfully, parent exiting
6.设置开机自启动MongoDB
[root@test2 mongodb]# echo "/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf" >> /etc/rc.local
/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf
7.测试：
(1)进入Mongodb的shell模式：

[root@test2 ~]# /usr/local/mongodb/bin/mongo
MongoDB shell version: 3.0.7
connecting to: test
Server has startup warnings:
2015-11-11T18:26:02.022+0800 I CONTROL  [initandlisten] ** WARNING: You are running this process as the root user, which is not recommended.
2015-11-11T18:26:02.022+0800 I CONTROL  [initandlisten]

2015-11-11T18:26:02.022+0800 I CONTROL  [initandlisten] **        We suggest setting it to 'never'
2015-11-11T18:26:02.022+0800 I CONTROL  [initandlisten]

2015-11-11T18:26:02.022+0800 I CONTROL  [initandlisten] **        We suggest setting it to 'never'
2015-11-11T18:26:02.022+0800 I CONTROL  [initandlisten]
>
  (2)查看数据库列表

> show dbsshow dbs
local  0.078GB
  (3)查看数据库版本

> db.version();db.version();
3.0.7
  (4)关闭数据库

[root@test2 bin]# /usr/local/mongodb/bin/mongod --shutdown --config /usr/local/mongodb/bin/mongodb.conf
2015-11-11T18:36:01.404+0800 I CONTROL  log file "/usr/local/mongodb/logs/mongodb.log" exists; moved to "/usr/local/mongodb/logs/mongodb.log.2015-11-11T10-36-01".
killing process with pid: 1449
    或使用kill

[root@test2 ~]# ps -ef |grep mongo
root       1505      1  0 18:37 ?        00:00:03 /usr/local/mongodb/bin/mongod --bind_ip localhost -f /usr/local/mongodb/bin/mongodb.conf
root       1544   1324  0 18:45 pts/2    00:00:00 grep mongo

[root@test2 ~]# kill 1505
注意：这个地方不能使用kill -9 pid，这样会导致数据丢失，同时mongodb还可能会报错。
如果使用kill -9 pid的方式关闭mongodb，并且mongodb不能正常启动，则需删除mongod.lock文件


[root@test2 bin]# kill rm -rf /usr/local/mongodb/data/mongod.lock
[root@test2 bin]# /usr/local/mongodb/bin/mongod --config /usr/local/mongodb/bin/mongodb.conf
