仲裁节点会自动被去掉

开启分片功能

#为数据库开启分片功能
sh.enableSharding("my_test")
#为指定集合开启分片功能
sh.shardCollection("my_test.my_test_datas",{"name":"hashed"})

测试

use my_test
for(var i=1;i<= 100;i++){
  db.my_test_datas.insert({"name":"test"+i,
  salary:(Math.random()*20000).toFixed(2)});
}

安全认证

登录任何一个mongos节点
必须要有admin用户，不然为指定数据库创建的用户一样没效果

use admin
创建管理员帐号

user admin
db.createUser(
{
user:"root",
pwd:"123456",
roles:[{role:"root",db:"admin"}]
})
  • 创建指定数据库的用户
lg_resume
db.createUser(
{
user:"lg_resume",
pwd:"abc321",
roles:[{role:"readWrite",db:"lg_resume"}]
})

查看用户

user admin
db.system.users.find().pretty()

创建key

在任意一台上面
生成密钥文件 并修改权限

openssl rand -base64 756 > /data/mongo/key/myKeyFile.file
chmod 600 /data/mongo/key/myKeyFile.file

将这个key复制到其它的所有服务上对应的目录

并设置权限
chmod 600 /data/mongo/key/myKeyFile.file

其它

安装psmisc
yum install psmisc
安装完之后可以使用killall 命令 快速关闭多个进程

killall mongod
killall mongos

所有的配置文件都增加

auth=true
keyFile=/data/mongo/key/myKeyFile.file

路由节点只增加

keyFile=/data/mongo/key/myKeyFile.file

重启

  1. 配置节点
  2. shard1节点
  3. shard2节点
  4. shard3节点
  5. 各个mongos节点

登录mongos节点

use admin
db.auth("root","123456")

use lg_resume
db.createUser(
{
user:"lagou_gx",
pwd:"abc321",
roles:[{role:"readWrite",db:"lg_resume"}]
})
sh.enableSharding("lg_resume")
#为指定集合开启分片功能
sh.shardCollection("lg_resume.lg_resume_datas",{"name":"hashed"})
  • 测试
for(var i=1;i<= 10;i++){
    
    
  db.lg_resume_datas.insert({
    
    "name":"test"+i,
  salary:(Math.random()*20000).toFixed(2)});
}

查看数据分布
