centos 安装 mongo3.0

官方网站传贴，每次去翻doc，麻烦

vi  /etc/yum.repos.d/mongodb-org-3.0.repo

[mongodb-org-3.0]name=MongoDB Repositorybaseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.0/x86_64/gpgcheck=0enabled=1

sudo yum install -y mongodb-org

#sudo yum install -y mongodb-org-3.0.7 mongodb-org-server-3.0.7 mongodb-org-shell-3.0.7 mongodb

 

vi /etc/selinux/config

SELINUX=disabled

#SELINUX=permissive

 

 

 

#卸载

sudo yum erase $(rpm -qa | grep mongodb-org)

sudo rm -r /var/log/mongodb

sudo rm -r /var/lib/mongo

启动命令:
cd ~/mongodb/m/bin
./mongod -f s.conf

cd ~/mongodb/s1/bin
./mongod -f s.conf

cd ~/mongodb/s2/bin
./mongod -f s.conf

cd ~/mongodb/a/bin
./mongod -f s.conf

配置：
cd ~/mongodb/m/bin
./mongo
use admin

cfg={ _id:"virus", members:[ {_id:0,host:'127.0.0.1:27017',priority:1}, {_id:1,host:'127.0.0.1:27018',priority:2},   
{_id:2,host:'127.0.0.1:27019',priority:3},  
{_id:3,host:'127.0.0.1:27010',arbiterOnly:true}] };  
rs.initiate(cfg) 

----当然可以按照下面这个来---

1、把文件拷贝到服务器上去

tar -zxvf mongxxx

mv mongodb-xxxx  mongodb

 

cd /mongodb

mkdir data

mkdir data/"节点名称"

mkdir log

 

2 、修改/etc/init.d/mongod

#把mongod传输到 /etc/rc.d/init.d/下面

vi  /etc/init.d/mongod

#修改配置文件路径

CONFIGFILE="/opt/mongodb/节点配置文件"

 

#注册服务

chmod +x /etc/init.d/mongod

chkconfig --add mongod

#chkconfig --level 5 mongod

chkconfig mongod on

chkconfig  --list  mongod 

 

3 上传

libstdc++xxxx.rpm

rpm -ivh   libstdc++xxxx.rpm

 

4 启动

service mongd start

#查看启动木有

ps -A 

#如果没有看日志

vi  /opt/mongodb/log/节点名称.log

 

5、配置home

vi /etc/profile

#最后添加

export MDB_HOME=/opt/mongodb

export  PATH=$PATH:$MDB_HOME/bin

 

source /etc/profile 

#或则

.  /etc/profile

 

#进入操作

mongo  172.30.1.x:27017 

 

 

 

6、 配置特殊的仲裁节点

#随便添加

 cfg={ _id:"testrs", members:[ {_id:0,host:'10.10.148.130:27017',priority:2}, {_id:1,host:'10.10.148.131:27017',priority:1},  

{_id:2,host:'10.10.148.132:27017',arbiterOnly:true}] };

#如果报错，把上的只留 _id和host

rs.initiate(cfg);

 

#手动添加仲裁

  rs.addArb(“192.168.1.50:10001″)

#手工添加slaver（如果仲裁和slaver在一起麻烦换个端口不要用27017）

 rs.add(“192.168.1.50:10001″)

#删除节点

rs.remove("192.168.1.50:10001")

设置启动用的代码改centos+Ubuntu的嘿嘿，偷懒啊。。。
