#杀掉master,看slave是否切换为master

$ kill -9 `ps -ef|grep mongod|grep -v grep|awk ‘{print $2}‘`

#此时再连接原来的slave(如果已经连着,直接enter.....),看到repset:SECONDARY> 变成repset:PRIMARY> 

repset:PRIMARY>  db.users.insert({username: "tangwan2", age: 22})

repset:PRIMARY> db.users.insert({username: "tangwan2", age: 22})

#再启动刚杀掉的master,可以看到它成了slave了

$ /opt/mongodb/bin/mongod -f /opt/mongodb/conf/mongodb.conf

$ /opt/mongodb/bin/mongo 192.168.1.21:27017

#检查它死后那段时间数据是否也复制过来了

repset:SECONDARY> db.users.find()

 

#用openssl生成密钥,用于集群间机器的信任,为心跳连接加密

$ yum -y install openssl

$ openssl rand -base64 741 > mongodb.key

 

#给mongodb添加用户和密码

erp;#数据库名

erp_user#用户名

zgtx123.com#密码

##创建用户前需要修改currentVersion,认证级别

repset:PRIMARY>  db.system.version.find()

repset:PRIMARY>  db.system.version.update({‘_id‘:‘authSchema‘},{$set:{‘currentVersion‘:3}})

repset:PRIMARY>  db.system.version.find()

##查看,创建,删除用户

repset:PRIMARY> use admin

repset:PRIMARY> db.system.users.find()

repset:PRIMARY> db.system.users.remove({user:"erp_user"})

repset:PRIMARY> use erp

switched to db erp

repset:PRIMARY> db.createUser( {"user":"erp_user","pwd":"zgtx123.com","roles":[{role:"readWrite",db:"erp"}]},{w:"majority",wtimeout:5000})

Successfully added user: {

"user" : "erp_user",

"roles" : [

{

"role" : "readWrite",

"db" : "erp"

}

]

}

##修改3个配置文件auth=true;重启mongodb

$ kill -9 `ps -ef|grep mongod|grep -v grep|awk ‘{print $2}‘`

$ /opt/mongodb/bin/mongod -f /opt/mongodb/conf/mongodb.conf

$ /opt/mongodb/bin/mongo 192.168.1.20:27017/erp -u erp_user -p#输入密码

> db.auth("erp_user", "zgtx123.com")     #也是一种认证方式
