mongo:
无法远程登录mongo：
修改/etc/mongo.conf中的bind_ip=127.0.0.1改为：
bind_ip=0.0.0.0,然后重启mongo:
sudo /etc/init.d/mongodb restart
先使用robo3t-gui工具连接了未配置认证（mongo.conf中auth=true处于注释状态）的mongo，在admin数据库下创建用户，发现有9中类型的role，创建root之后执行show users:
其中role类型有:
read,readWrite,
dbAdmin,userAdmin,clusterAdmin,
readAnyDatabase,readWriteAnyDatabase,
userAdminAnyDatabase,dbAdminAnyDatabase
首先不要开启认证，确保mongo.conf里的auth=true处于注释状态，先创建用户:
#db.createUser({'user':'myusr','pwd':'mypwd',roles:['readWrite','dbAdmin']})
如在admin下创建一个拥有所有权限的用户名：myusr，密码是mypwd,则方法是：
db.createUser({'user':'root','pwd':'123',"roles" : [ { "role" : "read", "db" : "admin" }, { "role" : "readWrite", "db" : "admin" }, { "role" : "dbAdmin", "db" : "admin" }, { "role" : "userAdmin", "db" : "admin" }, { "role" : "clusterAdmin", "db" : "admin" }, { "role" : "readAnyDatabase", "db" : "admin" }, { "role" : "readWriteAnyDatabase", "db" : "admin" }, { "role" : "userAdminAnyDatabase", "db" : "admin" }, { "role" : "dbAdminAnyDatabase", "db" : "admin" } ]})
格式化下看：
db.createUser({'user':'root','pwd':'123',"roles" : [ { "role" : "read", "db" : "admin" }, { "role" : "readWrite", "db" : "admin" }, { "role" : "dbAdmin", "db" : "admin" }, { "role" : "userAdmin", "db" : "admin" }, { "role" : "clusterAdmin", "db" : "admin" }, { "role" : "readAnyDatabase", "db" : "admin" }, { "role" : "readWriteAnyDatabase", "db" : "admin" }, { "role" : "userAdminAnyDatabase", "db" : "admin" }, { "role" : "dbAdminAnyDatabase", "db" : "admin" } ]})
然后执行show users:
show users;
{
"_id" : "admin.root",
"userId" : UUID("8d5b12e7-830b-4464-b14f-b56167e7a8ed"),
"user" : "root",
"db" : "admin",
"roles" : [
{
"role" : "read",
"db" : "admin"
},
{
"role" : "readWrite",
"db" : "admin"
},
{
"role" : "dbAdmin",
"db" : "admin"
},
{
"role" : "userAdmin",
"db" : "admin"
},
{
"role" : "clusterAdmin",
"db" : "admin"
},
{
"role" : "readAnyDatabase",
"db" : "admin"
},
{
"role" : "readWriteAnyDatabase",
"db" : "admin"
},
{
"role" : "userAdminAnyDatabase",
"db" : "admin"
},
{
"role" : "dbAdminAnyDatabase",
"db" : "admin"
}
]
}
此时可以连接成功
创建数据库:
use database_name
在数据库mydb上创建用户testusr,密码：123
use mydb
db.createUser({'user':'testusr','pwd':'123',"roles" : [ { "role" : "read", "db" : "mydb" }, { "role" : "readWrite", "db" : "mydb" }, { "role" : "dbAdmin", "db" : "mydb" }]})
用testusr登录mongo：
mongo -u testusr --authenticationDatabase mydb -h your_ip -p
mongo -u testusr your_ip:port/mydb -p
MongoDB shell version v4.2.2
