https://blog.csdn.net/ko0491/article/details/108764916
建立3個配置檔案
- mongo_27017.conf
#資料目錄
dbpath=/data/mongo/data/server1
#埠號
port=27017
bind_ip=0.0.0.0
#以後臺執行
fork=true
# 日誌路徑
logpath = /data/mongo/logs/server1.log
# 追加
logappend = true
# 授權
auth=false
#複製集
replSet=myCluster
- mongo_27018.conf
#資料目錄
dbpath=/data/mongo/data/server2
#埠號
port=27018
bind_ip=0.0.0.0
#以後臺執行
fork=true
# 日誌路徑
logpath = /data/mongo/logs/server2.log
# 追加
logappend = true
# 授權
auth=false
#複製集
replSet=myCluster
- mongo_27019.conf
#資料目錄
dbpath=/data/mongo/data/server3
#埠號
port=27019
bind_ip=0.0.0.0
#以後臺執行
fork=true
# 日誌路徑
logpath = /data/mongo/logs/server3.log
# 追加
logappend = true
# 授權
auth=false
#複製集
replSet=myCluster
在data目錄下建立相就的目錄
分別啟動
./mongod -f ../mongo_27017.conf
./mongod -f ../mongo_27018.conf
./mongod -f ../mongo_27019.conf
分別連線
./mongo --host=192.168.181.135 --port=27017
./mongo --host=192.168.181.135 --port=27018
./mongo --host=192.168.181.135 --port=27019
在任意一個節點
rs.initiate({
_id: "myCluster",
members: [{
_id: 0,
host: "192.168.181.135:27017",
"priority":10
},{
_id: 1,
host: "192.168.181.135:27018"
},{
_id: 2,
host: "192.168.181.135:27019"
}]
})
- 檢視狀態

節點的動態增刪
增加節點
rs.add("192.168.181.135:37019")
刪除slave 節點
rs.remove("192.168.181.135:37019")
調整複製集配置
var conf = rs.conf()
// 將0號節點的優先順序調整為10
conf.members[0].priority = 10;
// 將1號節點調整為hidden節點
conf.members[1].hidden = true;
// hidden節點必須配置{priority: 0}
conf.members[1].priority = 0;
// 應用以上調整
rs.reconfig(conf);
其它配置
# /usr/local/mongodb/mongodb.conf
systemLog:
destination: file
path: /usr/local/mongodb/log/mongodb.log # log path
logAppend: true
storage:
dbPath: /usr/local/mongodb/data/ # data directory
net:
bindIp: 0.0.0.0

maxIncomingConnections: 500
replication:
enableMajorityReadConcern: true

pidFilePath: /usr/local/mongodb/run/mongodb.pid
測試
myCluster:PRIMARY> use local
switched to db local
myCluster:PRIMARY> show tables
oplog.rs
replset.election
replset.minvalid
replset.oplogTruncateAfterPoint
startup_log
- 插入資料
myCluster:PRIMARY> show dbs
admin 0.000GB
config 0.000GB
local 0.000GB
myCluster:PRIMARY> use myresume
switched to db myresume
myCluster:PRIMARY> db.my_test.insert({name:'zhangsan',age:18})
WriteResult({ "nInserted" : 1 })
myCluster:PRIMARY> db.my_test.find()
{ "_id" : ObjectId("5f706974ada3cc994b4d8e41"), "name" : "zhangsan", "age" : 18 }
myCluster:PRIMARY> show tables;
my_test
從庫檢視
rs.slaveOk()
不然不能查
檢視從節點,都有
- 從節點插入失敗
myCluster:SECONDARY> db.my_test.insert({name:"lisi",age:33})
WriteCommandError({
"operationTime" : Timestamp(1601203170, 1),
"ok" : 0,

有仲裁節點複製集搭建
_id 整數 _id:0 複製集中的標示
host 字串 host:“主機:埠” 節點主機名
arbiterOnly 布林值 arbiterOnly:true 是否為仲裁(裁判)節點
priority（權重）
整數 priority=0|1 預設1，是否有資格變成主節點，取值範圍0-1000，0永遠不
會變成主節點
hidden 布林值 hidden=true|false，0|1 隱藏，權重必須為0，才可以設定
votes 整數 votes= 0|1 投票，是否為投票節點,0 不投票，1投票
slaveDelay 整數 slaveDelay=3600 從庫的延遲多少秒
buildIndexes 布林值 buildIndexes=true|false,0|1 主庫的索引，從庫也建立，_id索引無效
和上面的配置步驟相同 只是增加了 一個特殊的仲裁節點
注入節點 執行 rs.addArb(“IP:埠”);
rs.addArb(“192.168.181.135:27020”)
或者重新配置
只能在主節點下進行
var cfg ={
_id: "myCluster",
"protocolVersion" : 1,
members: [{
_id: 0,
host: "192.168.181.135:27017",
