創(chuàng)建mongodb分片集群 + keyFile認證一、環(huán)境準備 1. 服務器節(jié)點信息【三臺服務器】 二、 集群環(huán)境設計 1. 三個 分片 復制集合 三、mongodb 安裝、`tar -zxvf mongodb-linux-x86_64-rhel70-4.2.5.tgz` mv mongodb-linux-x86_64-rhel70-4.2.5 /opt/mongodb4.2
四、添加環(huán)境變量 1. vim /etc/profile 五、搭建mongodb分片復制集1. 分別在三臺服務器(x.x.x.159、x.x.x.160、 x.x.x.161)節(jié)點 執(zhí)行如下命令 2. mongodb分片集群 配置文件 目錄 mkdir -p /opt/mongodb4.2/conf 3. 分片日志目錄 mkdir -p /opt/mongodb4.2/logs 4. 創(chuàng)建集群安全認證機制KeyFile openssl rand -base64 736 > /opt/mongodb4.2/conf/mongodb.keyfile Notice: keyfile 必須滿足以下條件: 1) 至少6個字符，小于1024字節(jié)。
5. 創(chuàng)建分片 數(shù)據(jù)存儲目錄 mkdir -p /opt/mongodb4.2/data/db1 【分片1】 mkdir -p /opt/mongodb4.2/data/db2 【分片2】 mkdir -p /opt/mongodb4.2/data/db3 【分片3】 6. 創(chuàng)建分片配置文件 vim /opt/mongodb4.2/conf/mongodb1.conf 【分片1 配置文件】

六、啟動 分片復制集1. 分別在三臺服務器(x.x.x.159、x.x.x.160、 x.x.x.161)節(jié)點 執(zhí)行如下命令 2. mongod -f /opt/mongodb4.2/conf/mongodb1.conf 3. mongod -f /opt/mongodb4.2/conf/mongodb2.conf 4. mongod -f /opt/mongodb4.2/conf/mongodb3.conf 七、 初始化分片復制集 并 設置 分片復制集賬號 1. 在其中任意一臺節(jié)點服務器登錄 本人使用 x.x.x.159節(jié)點 var conf = {
_id:'jxk',
members:[
{_id:1, host:'x.x.x.159:27017'},
{_id:2, host:'x.x.x.160:27017'},
{_id:3, host:'x.x.x.161:27017'},
],
}
rs.initiate(conf)
rs.status()
4. 找到mongodb自己選舉出來的 主庫 輸入命令： use admin
db.createUser({
user: "username",
pwd : "password",
roles:[
{role:"root", db:"admin"}
]
})
db.auth("username", "password")
八、搭建config節(jié)點復制集1. 分別在三臺服務器(x.x.x.159、x.x.x.160、 x.x.x.161)節(jié)點 執(zhí)行如下命令 2. 創(chuàng)建 config 數(shù)據(jù)存儲 目錄 mkdir -p /opt/mongodb4.2/mongo-cfg/data 3. 創(chuàng)建 config 日志 目錄 mkdir -p /opt/mongodb4.2/mongo-cfg/logs 4. 創(chuàng)建 config復制集 配置文件 vim /opt/mongodb4.2/conf/mongodb-cfg.conf
systemLog:
destination: file
logAppend: true
path: /opt/mongodb4.2/logs/mongodb3.log
storage:
journal:
enabled: true
dbPath: /opt/mongodb4.2/mongo-cfg/data
directoryPerDB: true
wiredTiger:
engineConfig:
cacaeSizeGB: 2
directoryForIndexes: true
collectionConfig:
blockCompressor: zstd
indexConfig:
prefixCompression: true
net:
port: 28018
bindIp: x.x.x.159
replication:
oplogSizeMB: 4000
replSetName: configReplSet
sharding:
clusterRole: configsvr
processManagement:
fork: true
5. 啟動config節(jié)點復制集 mongod -f /opt/mongodb4.2/conf/mongodb-cfg.conf 6. 登錄config節(jié)點 mongo -host x.x.x.(159/160/161) -port 28018 7.初始化 config節(jié)點 var conf = {
_id:'configReplSet',
members:[
{_id:0, host:"x.x.x.159:28018"},
{_id:1, host:"x.x.x.160:28018"},
{_id:2, host:"x.x.x.161:28018"},
]
}
rs.initiate(conf)
rs.status()
8. 創(chuàng)建認證用戶 use admin
db.createUser({
user: "username",
pwd : "password",
roles:[
{role:"root", db:"admin"}
]
})
db.auth("username", "password")
9. 開啟config復制集 認證 security:
authorization: enabled
keyFile: /opt/mongodb4.2/conf/mongodb.keyfile
clusterAuthMode: keyFile
啟動 config復制集 九、搭建mongos節(jié)點(x.x.18.159) 1. 在 x.x.x.159 服務器上搭建客戶端 mkdir -p /opt/mongodb4.2/mongos/logs 3. 創(chuàng)建mongos 配置文件 systemLog:
destination: file
logAppend: true
path: /opt/mongodb4.2/mongos/logs/mongodb.log
net:
port: 27000
bindIp: 0.0.0.0
sharding:
configDB: configReplSet/x.x.x.159:28018,x.x.x.160:28018,x.x.x.160:28018,
processManagement:
fork: true
security:
keyFile: /opt/mongodb4.2/conf/mongodb.keyfile
clusterAuthMode: keyFile
4. 啟動mongos mongos -f /opt/mongodb4.2/conf/mongos.conf 5. 登錄并初始化 mongos mongo -port 27000
use admin
db.auth("username", "password") #這里使用的賬號是 config復制集的賬號
db.runCommand({
addshard:"jxk1/x.x.x.159:27017,x.x.x.160:27017,x.x.x.161:27017,",
name: "shard1"
});
db.runCommand({
addshard:"jxk2/x.x.x.159:27018,x.x.x.160:27018,x.x.x.161:27018,",
name: "shard1"
});
db.runCommand({
addshard:"jxk3/x.x.x.159:27019,x.x.x.160:27019,x.x.x.161:27019,",
name: "shard1"
})
6. 測試是否搭建成功 db.runCommand( {enablesharding:"dbtest"})
db.runCommand( {shardcollection:"dbtest.one", key:{id:1} })
use dbtest
var tmp = [];
for(var i =0; i<10000000; i++){
tmp.push({ 'id':i, "name":"lunck dog " + i});
}
db.one.insertMany(tmp);
sh.status()
十、常用命令匯總1. 分片命令 mongod -f /opt/mongodb4.2/conf/mongodb1.conf 啟動 mongod -f /opt/mongodb4.2/conf/mongodb1.conf --shutdown 關(guān)閉 OR mongo -port 27017 use admin db.shutdownServers()
2.config 復制集命令 mongod -f /opt/mongodb4.2/conf/mongodb-cfg.conf 啟動 mongod -f /opt/mongodb4.2/conf/mongodb-cfg.conf --shutdown 關(guān)閉 3. mongos 命令 mongos -f /opt/mongodb4.2/conf/mongos.conf 啟動 mongo -port 27017 關(guān)閉 use admin db.shutdownServers()
