linux下安装mongodb(非root用户)

安装mongodb
1.下载
mongodb-linux-x86_64-2.6.5.tgz

2.创建用户
[root@node2 soft]# groupadd mongo
[root@node2 soft]# useradd -g mongo mongo
[root@node2 ~]# passwd mongo

3.解压缩
[root@node2 soft]# tar -zxvf mongodb-linux-x86_64-2.6.5.tgz

4.创建mongodb目录
mkdir -p /db/mongodb

5.将mongodb迁移到相应目录
mv mongodb-linux-x86_64-2.6.5 /db/mongodb/mongodb
chown -R mongo:mongo ./mongodb

6.使用mongo用户登录创建数据文件和日志文件
[mongo@node2 db]$ mkdir -p /db/mongodb/data
[mongo@node2 db]$ mkdir -p /db/mongodb/log
[mongo@node2 db]$ mkdir -p /db/mongodb/conf
[mongo@node2 db]$ touch /db/mongodb/log/logs

mongodb配置文件参数

port=10000
fork=true
dbpath=/opt/mongodb/data
logpath=/opt/mongodb/log/logs
logappend=true
shardsvr=true
master=true
quiet=true

7.为mongo用户创建环境变量
cd ~
vi .bash_profile
设置PATH变量如下:
PATH=/db/mongodb/mongodb/bin:$PATH:$HOME/bin

8.启动mongodb(mongo用户)

./mongod -f /opt/mongodb/conf/master.cnf

权限问题，使用sudo启动
[mongo@node2 ~]$ mongod --dbpath=/db/mongodb/data --logpath=/db/mongodb/log/logs --logappend --port=27017 --fork

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[sudo] password for mongo:
mongo is not in the sudoers file.  This incident will be reported.

解决办法:
A.chmod u+w /etc/sudoers

B.编辑sudoers文件
vi /etc/sudoers
找到这行 root ALL=(ALL) ALL,在他下面添加xxx ALL=(ALL) ALL (这里的xxx是你的用户名)
如:
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
mongo   ALL=(ALL)       ALL

C.撤销权限
chmod u-w /etc/sudoers

9.再次启动
[mongo@node2 ~]$ sudo mongod --dbpath=/db/mongodb/data --logpath=/db/mongodb/log/logs --logappend --port=27017 --fork

10.关闭

[mongo@node2 ~]$ sudo mongo admin --eval "db.shutdownServer()"
