red hat 安装 mongodb

发现更方便的安装方法，直接下载压缩包，解压后把目录放到/usr/local目录下，然后在把mongodb/bin加入到path中。这样就可以使用了：

参考：http://www.runoob.com/mongodb/mongodb-linux-install.html

下载完安装包，并解压 tgz（以下演示的是 64 位 Linux上的安装） 。
curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.0.6.tgz    # 下载
tar -zxvf mongodb-linux-x86_64-3.0.6.tgz                                   # 解压

mv  mongodb-linux-x86_64-3.0.6/ /usr/local/mongodb                         # 将解压包拷贝到指定目录

MongoDB 的可执行文件位于 bin 目录下，所以可以将其添加到 PATH 路径中：
export PATH=<mongodb-install-directory>/bin:$PATH
< mongodb-install-directory > 为你 MongoDB 的安装路径。如本文的 /usr/local/mongodb

刚开始参照官网（https://docs.mongodb.org/master/tutorial/install-mongodb-on-red-hat/）上的步骤来安装，但是总是访问不了，提示http连接超时，大概是被墙了，因为ping 这个域名也不通。后来打算从源码开始安装，从github下载源码之后又有python版本跟yum之间依赖的问题不好解决，服务器上的软件版本都太老了，一筹莫展之后发现官网上还有之前更早的版本，比如2.6的，索性就试试吧

新建/etc/yum.repos.d/mongodb-org-2.6.repo，写入如下内容

[mongodb-org-2.6]
name=MongoDB 2.6 Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/
gpgcheck=0
enabled=1

因为

To install a specific release of MongoDB, specify each component package individually and append the version number to the package name, as in the following example

所以在

http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/RPMS/

里面找到2.6的文件，比如

mongodb-org-2.6.0-1

,执行

yum install -y mongodb-org-2.6.0-1

系统会各种dependency都给安上

启动后如果遇到空间不足的问题，可以参考这里(http://stackoverflow.com/questions/14584393/why-getting-error-mongod-dead-but-subsys-locked-and-insufficient-free-space-for)

我在执行

service mongod start

时提示

source: command not found

,只好执行

/etc/init.d/mongod start

或者

/sbin/service mongod start

来启动mongod。
