Centos6.5下搭建Mongodb服务

yanfei

　　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] **        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
