Linux下安装mongodb详细过程

: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：

[root@localhost yum.repos.d]# yum install mongodb

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：

2015-05-08T11:33:14.789+0800 I CONTROL [initandlisten] ** WARNING: soft rlimits too low. rlimits set to 1024 processes, 64000 files. Number of processes should be at least 32000 : 0.5 times number of files.

可以尝试：

cd /etc/security/limits.d
vim 90-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
