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：
1 [mongodb-org-3.0] 2 name=MongoDB 3.0 Repository 3 baseurl=https://repo.mongodb.org/yum/redhat/6/mongodb-org/3.0/x86_64/ 4 gpgcheck=0 5 enabled=1
: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：
[[email protected] yum.repos.d]# yum install mongodb Loaded plugins: fastestmirror Setting up Install Process Loading mirror speeds from cached hostfile * base: mirror.bit.edu.cn * epel: mirrors.aliyun.com * extras: mirror.neu.edu.cn * updates: mirrors.btte.net Resolving Dependencies --> Running transaction check ---> Package mongodb.x86_64 0:2.4.13-1.el6 will be installed --> Processing Conflict: mongodb-org-3.0.2-1.el6.x86_64 conflicts mongodb --> Processing Conflict: mongodb-org-mongos-3.0.2-1.el6.x86_64 conflicts mongodb --> Processing Conflict: mongodb-org-server-3.0.2-1.el6.x86_64 conflicts mongodb --> Processing Conflict: mongodb-org-shell-3.0.2-1.el6.x86_64 conflicts mongodb --> Processing Conflict: mongodb-org-tools-3.0.2-1.el6.x86_64 conflicts mongodb --> Finished Dependency Resolution Error: mongodb-org-mongos conflicts with mongodb-2.4.13-1.el6.x86_64 Error: mongodb-org-server conflicts with mongodb-2.4.13-1.el6.x86_64 Error: mongodb-org-tools conflicts with mongodb-2.4.13-1.el6.x86_64 Error: mongodb-org-shell conflicts with mongodb-2.4.13-1.el6.x86_64 Error: mongodb-org conflicts with mongodb-2.4.13-1.el6.x86_64 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 mongodnetstat -aux|grep mongod
