修改配置檔案參數

master
[root@iZ2zegc312qxcxs61cotxlZ opt]# cat /usr/local/mongodb/mongdb.conf
port = 27017
logpath = /usr/local/mongodb/logs/mongodb.log
pidfilepath=/var/run/mongodb/mongodb.pid
dbpath=/data/mongodb
master = true           #确定我是主伺服器
source = 172.17.165.230
fork = true
logappend = true
#auth = true

slave
[root@iZ2zejbqrpwrmr4mjy0u9fZ ~]# cat /usr/local/mongodb/mongodb.conf 
port = 27017    #端口号
logpath = /usr/local/mongodb/logs/mongodb.log   #日志位置
pidfilepath=/var/run/mongodb/mongodb.pid        #PID 位置
dbpath=/data/mongodb                            #資料存放位置
slave = true                                    #模式 确定我是從伺服器
source = 172.17.165.245                         #規定從屬于哪個ip  注意：ip是主伺服器的
fork = true                                     #設定背景運作
logappend = true                                #日志輸出格式
#auth = true                                    #開啟認證           

設定環境變量

[root@iZ2zejbqrpwrmr4mjy0u9fZ ~]# vim /etc/profile
export PATH=/usr/local/mongodb/bin:$PATH
