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：
# wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.2.3.tgz
解压并复制到/opt/mongo/目录
# tar zxvf mongodb-linux-x86_64-2.2.3.tgz -C /tmp/
#mkdir /opt/mongo
# 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
# for i in `ls /opt/mongo/bin`
> do
> ln -s /opt/mongo/bin/$i /usr/bin/$i
> done
#
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
# mkdir /data/db/
# 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
# mongod --config /etc/mongodb.conf
can't open for log file: errno:2 No such file or directory
log文件不存在？建立一下再启动
# mkdir -p /var/log/mongodb/ && mongod --config /etc/mongodb.conf
all output going to: /var/log/mongodb/mongod.log
forked process: 27030
#
然后打开MongoDB Shell看看
# 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
# cat /var/log/mongodb/mongod.log

可用控件不足。。照log提示加--smallfiles再启试试
# mongod --config /etc/mongodb.conf --smallfiles
all output going to: /var/log/mongodb/mongod.log
forked process: 27054
child process started successfully, parent exiting
# mongo
MongoDB shell version: 2.2.3

>
成功进入MongoDB shell
