MongoDB Master/Slaver配置

1. 首先創建Mongo Master
   /home/hrj/mongodb-linux-i686-static-1.6.5/bin/mongod --master --dbpath /home/hrj/mongodb_data --auth --maxConns 50    --port 6688
   
   
2. 其次創建Mongo Slaver
   /home/hrj/mongodb-linux-i686-static-1.6.5/bin/mongod --slave --source myna5.sds.cnb.yahoo.com:6688 --auth --maxConns 50 --auth    --port 6689 --fastsync --autoresync --dbpath /home/hrj/mongodb_slave_data
3. 創建Master、Slaver帳號
   ~/mongodb-linux-i686-static-1.6.5/bin/mongo 127.0.0.1:6689 ### 在Slaver上創建帳號
   > use local
   switched to db local
   > db.addUser('hrj','xxx')
   {
                   "_id" : ObjectId("4d6f6527013fcbcc74575c20"),
                   "user" : "hrj",
                   "readOnly" : false,
                   "pwd" : "b27edaa5a8858aa3d46b60698fce1359"
   } 
    ~/mongodb-linux-i686-static-1.6.5/bin/mongo 127.0.0.1:6688 ### 在Master上創建帳號
   MongoDB shell version: 1.6.5
   connecting to: 127.0.0.1:6688/test
   >use local
   switched to db local
   > db.addUser('hrj','xxx')
   {
                   "_id" : ObjectId("4d6f6527013fcbcc74575c20"),
                   "user" : "hrj",
                   "readOnly" : false,
                   "pwd" : "b27edaa5a8858aa3d46b60698fce1359"
   }
   >use test ###添加帳號認證
   switched to db local
   > db.auth('hrj','xxx')
4. 向Master加載數據，測試Slaver是否正常同步
   ###Master
   ~/mongodb-linux-i686-static-1.6.5/bin/mongo 127.0.0.1:6688
   MongoDB shell version: 1.6.5
   connecting to: 127.0.0.1:6688/test                                
   > db.foo.save({'mongodb':'hello world'}) ###導入數據
   > db.foo.find()   ###查詢數據                                             
   { "_id" : ObjectId("4d6f72c6d807e8561b0f3db5"), "mongodb" : "hello world" }
   ###Slaver
   ~/mongodb-linux-i686-static-1.6.5/bin/mongo 127.0.0.1:6689
   MongoDB shell version: 1.6.5
   connecting to: 127.0.0.1:6689/test
   > db.foo.find() ###查詢Slaver同步數據
   { "_id" : ObjectId("4d6f72c6d807e8561b0f3db5"), "mongodb" : "hello world" }
   > db.foo.save({'mongodb':'hello world test 1'}) ###Slaver導入數據，提示"not master"
   not master

1. 停止Slave進程(mongod)
2. 刪除Slave數據目錄中的local.*
3. 以--master模式啟動Slave
