MongoDB副本集创建与认证（六）
一，修改配置文件，重启服务
示例节点：
1,x.x.x.89
2,x.x.x.62
3,x.x.x.143
vim /etc/mongo.conf
bindIp: 0.0.0.0
replication:
replSetName: testx
启动服务，登录
[root@iZj6chbmmjvrepa139fxb2Z mongo]# service mongod restart
Stopping mongod: [ OK ]
Starting mongod: [ OK ]
执行以下操作
PS：三台节点进行同样操作，重启服务。
二，以x.x.x.89为主，在此节点操作
登录之后
这是正常的
配置副本集
稍等几秒
PRIMARY为主
MongoDB只能在主节点进行写入操作
配置参数：
config 定义集合信息
rs.initate(config) 初始化副本信息
ok：1代表创建成功
testx:PRIMARY> rs.conf()
{
"_id" : "testx",
"version" : 1,
"protocolVersion" : NumberLong(1),
"members" : [
{
"_id" : 0,
"host" : "x.x.x.89:27017",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 10,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
},
{
"_id" : 1,
"host" : "x.x.x.62:27017",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 9,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
},
{
"_id" : 2,
"host" : "x.x.x.143:27017",
"arbiterOnly" : false,
"buildIndexes" : true,
"hidden" : false,
"priority" : 1,
"tags" : {
},
"slaveDelay" : NumberLong(0),
"votes" : 1
}
],
"settings" : {
"chainingAllowed" : true,
"heartbeatIntervalMillis" : 2000,
"heartbeatTimeoutSecs" : 10,
"electionTimeoutMillis" : 10000,
"catchUpTimeoutMillis" : -1,
"catchUpTakeoverDelayMillis" : 30000,
"getLastErrorModes" : {
},
"getLastErrorDefaults" : {
"w" : 1,
"wtimeout" : 0
},
"replicaSetId" : ObjectId("5a69a8695dcaecbc86df9843")
}
}
testx:PRIMARY>
副本集信息如上
三，认证
创建帐号，详细参阅（五）
创建副本集认证key文件
退出并修改配置文件
security:
authorization: enabled
keyFile: /MongoDB/key/mongodb-keyfile
重启服务
生成副本集key文件： 注意，三个节点必须要用同一份keyfile，在一台机器生成，拷贝到另外两台，并且修改成 600 的文件属性
[root@iZj6chbmmjvrepa139fxb2Z mongo]# openssl rand -base64 90 -out ./keyfile
[root@iZj6chbmmjvrepa139fxb2Z mongo]# chmod 600 keyfile
[root@iZj6chbmmjvrepa139fxb2Z mongo]# ll keyfile
-rw------- 1 root root 122 Jan 25 18:07 keyfile
PS：key文件与配置文件中路径一致
修改每个节点的mongo服务，打开认证。重启每个节点的mongodb服务，
security:
authorization: enabled
keyFile: /MongoDB/key/mongodb-keyfile
四，测试
testx:PRIMARY> db.auth('dbadmin','xxx')
1
testx:PRIMARY> rs.conf()
