Centos6.5下搭建Mongodb服务

1.系统版本

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

2.下载MongoDB 到/usr/loca/

 [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

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]   2015-11-11T18:26:02.022+0800 I CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'.  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] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.  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 mongoroot       1505      1  0 18:37 ?        00:00:03 /usr/local/mongodb/bin/mongod --bind_ip localhost -f /usr/local/mongodb/bin/mongodb.confroot       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
