MongoDB 錯誤彙總

錯誤1. ERROR: child process failed, exited with error number 100

可能原因：

1.沒有正確關閉服務

2.服務已經啟動

3.conf文件的參數配置錯誤。

錯誤2. "errmsg" : "not authorized on admin to execute command { shutdown: 1.0, $clusterTime: { clusterTime: Timestamp(1519725156, 1), signature: { hash: BinData(0, 476DC7E7EFED899078F2044EA1E58163CC9D5BC9), keyId: 6527148863013257217 } }, $db: \"admin\" }"

沒有許可權執行相關命令，可以通過驗證相關許可權，或者使用賬號密碼登入。

use admin;

db.auth("test","test") 註意這裡是逗號

然後再執行相關命令。

錯誤3. "errmsg" : "Quorum check failed because not enough voting nodes responded; required 2 but only the following 1 voting nodes responded: localhost.localdomain:27017; the following nodes did not respond affirmatively: localhost:27018 failed with not authorized on admin to execute command { replSetHeartbeat: \"rsmxqtest\", pv: 1, v: 2, from: \"localhost.localdomain:27017\", fromId: 0, checkEmpty: false }",

1.創建一個keyfile

openssl rand -base64 756 > /mongodb27010/autokey

chmod 400 /mongodb27010/autokey

2.將keyfile拷貝到其他從節點

3.在每個節點的conf文件中添加keyfile

keyFile = /mongodb27010/autokey

錯誤4. "errmsg" : "not master and slaveOk=false"

設置從節點允許讀操作

rs.slaveOk();
