Linux下安装mongodb详细过程

本次安装mongodb使用yum.repo方式。详细过程请参考,也列出一些安装过程中的错误,欢迎指正。

mongodb版本:3.0

先在linux下cd 到 /etc/yum.repos.d/

新建脚本文件mongodb-org-3.0.repo:

 [mongodb-org-3.0]
name=MongoDB 3.0 Repository
baseurl=https://repo.mongodb.org/yum/redhat/6/mongodb-org/3.0/x86_64/
gpgcheck=
enabled=

:wq保存后,清理yum资源

yum clean all

然后搜索下源

yum search mongodb

以搜索出来的名称为准。

上图search后出来的结果是mongodb-org.x86_64,然后mongo安装即可

yum install mongodb-org.x86_64

注:在安装过程中,如果遇到下面的错误:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

解决方法如下:

 yum install mongodb-org.x86_64 --skip-broken

跳过依赖关系就可以安装了。

mongod启动:

service mongod start

关闭(查找到进程然后kill掉):

ps -ef|grep mongod
kill xx pid

如果存在类似下面的一些警告:

I CONTROL  [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/enabled is 'always'.
I CONTROL [initandlisten] ** We suggest setting it to 'never'
I CONTROL [initandlisten]
I CONTROL [initandlisten] ** WARNING: /sys/kernel/mm/transparent_hugepage/defrag is 'always'.
I CONTROL [initandlisten] ** We suggest setting it to 'never'
echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
echo "never" > /sys/kernel/mm/transparent_hugepage/defrag

请参考下面资料:http://bbs.51cto.com/thread-1146184-1.html

如果有遇到这种错误:

--08T11::14.789+ I CONTROL [initandlisten] ** WARNING: soft rlimits too low. rlimits set to  processes,  files. Number of processes should be at least  : 0.5 times number of files.

可以尝试:

cd /etc/security/limits.d
vim -nproc.conf

* soft nproc 32000

root soft nproc unlimited

将第一行改成提示的值(此处的值:Number of processes should be at least 32000)

关闭mongodb:

mongod -f /etc/mongod.conf --shutdown

查看mongo状态:

service mongod status

启动mongo:

mongod -f /etc/mongod.conf

查看运行状态:

ps aux|grep mongod
netstat -aux|grep mongod
