安装及配置MONGODB CLUSTER

gznz12345

　　主服务器：master 10.1.1.3
　　从服务器：slave 10.1.1.4
　　因为我是在VPS上安装的mongodb所以使用axel 来加速yum下载速度！
　　添加安装mongodb yum源：
　　# vim /etc/yum.repos.d/mongodb.repo
　　[mongodb]
　　name=MongoDB Repository
　　baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/
　　gpgcheck=0
　　enabled=1
　　在主、从上都执行以下命令：
　　# yum -y install mongo-10gen mongo-10gen-server
　　安装完成后！
　　配置主服务器：10.1.1.3 master
　　[root@master]# cat /etc/mongod.conf
　　logpath = /var/log/mongo/mongod.log
　　logappend = true
　　fork = true
　　port = 27017
　　dbpath = /var/lib/mongo
　　pidfilepath = /var/run/mongodb/mongod.pid
　　master = true
　　source = 10.1.1.4 #从服务器ip
　　配置从服务器：10.1.1.4 slave1
　　[root@master]# cat /etc/mongod.conf
　　logpath = /var/log/mongo/mongod.log
　　logappend = true
　　fork = true
　　port = 27017
　　dbpath = /var/lib/mongo
　　pidfilepath = /var/run/mongodb/mongod.pid
　　slave = true
　　source = 10.1.1.3 #主服务器ip
　　启动主数据库
　　# service mongod start
　　# chkconfig mongod on
　　启动从数据库
　　# service mongod start
　　# chkconfig mongod on
　　查看一下主服务器，日志数据库是否同步成功！
　　[root@master ~]# tail -f /var/log/mongo/mongod.log
