MongoDB学习笔记【1】-- 安装启动
大部分内容根据MongoDB官方手册整理：http://docs.mongodb.org/manual/contents/
环境CentOS5.7 x86_64
下载：
[root@slayer Pkgs]# wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.2.3.tgz
解压并复制到/opt/mongo/目录
[root@slayer bin]# tar zxvf mongodb-linux-x86_64-2.2.3.tgz -C /tmp/ [root@slayer ~]#mkdir /opt/mongo [root@slayer ~]# cp -R /tmp/mongodb-linux-x86_64-2.2.3/* /opt/mongo/
给mongodb的可执行文件建立软连接放到/usr/bin目录
[root@slayer ~]# for i in `ls /opt/mongo/bin` > do > ln -s /opt/mongo/bin/$i /usr/bin/$i > done [root@slayer ~]#
建立数据库目录,这里我不准备root来运行，所以不需要更改目录所有权
[root@slayer ~]# mkdir /data/db/ [root@slayer ~]# chmod 777 /data/db/
vi /etc/mongodb.conf建立配置文件并写入以下内容
fork = true bind_ip = 127.0.0.1 port = 27017 quiet = true dbpath = /data/db logpath = /var/log/mongodb/mongod.log logappend = true journal = true
启动mongodb
[root@slayer ~]# mongod --config /etc/mongodb.conf can't open [/var/log/mongodb/mongod.log] for log file: errno:2 No such file or directory
log文件不存在？建立一下再启动
[root@slayer ~]# mkdir -p /var/log/mongodb/ && mongod --config /etc/mongodb.conf all output going to: /var/log/mongodb/mongod.log forked process: 27030 [root@slayer ~]#
然后打开MongoDB Shell看看
[root@slayer ~]# mongo MongoDB shell version: 2.2.3 connecting to: test Thu Dec 13 11:29:13 Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91 exception: connect failed
连接失败，看看log文件是什么问题 cat /var/log/mongodb/mongod.log
[root@slayer ~]# cat /var/log/mongodb/mongod.log Thu Dec 13 11:26:34 [initandlisten] MongoDB starting : pid=27030 port=27017 dbpath=/data/db 64-bit host=postgresql Thu Dec 13 11:26:34 [initandlisten] db version v2.2.3, pdfile version 4.5 Thu Dec 13 11:26:34 [initandlisten] git version: f570771a5d8a3846eb7586eaffcf4c2f4a96bf08 Thu Dec 13 11:26:34 [initandlisten] build info: Linux ip-10-2-29-40 2.6.21.7-2.ec2.v1.2.fc8xen #1 SMP Fri Nov 20 17:48:28 EST 2009 x86_64 BOOST_LIB_VERSION=1_49 Thu Dec 13 11:26:34 [initandlisten] options: { bind_ip: "127.0.0.1", config: "/etc/mongodb.conf", dbpath: "/data/db", fork: "true", journal: "true", logappend: "true", logpath: "/var/log/mongodb/mongod.log", port: 27017, quiet: "true" } Thu Dec 13 11:26:34 [initandlisten] journal dir=/data/db/journal Thu Dec 13 11:26:34 [initandlisten] recover : no journal files present, no recovery needed Thu Dec 13 11:26:34 [initandlisten] Thu Dec 13 11:26:34 [initandlisten] ERROR: Insufficient free space for journal files Thu Dec 13 11:26:34 [initandlisten] Please make at least 3379MB available in /data/db/journal or use --smallfiles Thu Dec 13 11:26:34 [initandlisten] Thu Dec 13 11:26:34 [initandlisten] exception in initAndListen: 15926 Insufficient free space for journals, terminating Thu Dec 13 11:26:34 dbexit: Thu Dec 13 11:26:34 [initandlisten] shutdown: going to close listening sockets...

可用控件不足。。照log提示加--smallfiles再启试试
[root@slayer ~]# mongod --config /etc/mongodb.conf --smallfiles all output going to: /var/log/mongodb/mongod.log forked process: 27054 child process started successfully, parent exiting [root@slayer ~]# mongo MongoDB shell version: 2.2.3 connecting to: test >
成功进入MongoDB shell
