#### 路由节点设置

```shell
# 创建 路由节点日志文件夹
mkdir -p route/logs
# 路由节点 27017
port=27017
bind_ip=0.0.0.0
fork=true
logpath=route/logs/route.log
configdb=configsvr/10.10.10.205:17011,10.10.10.205:17013,10.10.10.205:17015
```



#### 路由节点添加分片

```shell
./bin/mongo --port 27017
# 分片一
sh.addShard("shard1/10.10.10.205:37011,10.10.10.205:37013,10.10.10.205:37015");
# 分片二
sh.addShard("shard1/10.10.10.205:47011,10.10.10.205:47013,10.10.10.205:47015");
# 分片三
sh.addShard("shard1/10.10.10.205:57011,10.10.10.205:57013,10.10.10.205:57015");
# 分片四
sh.addShard("shard1/10.10.10.205:58011,10.10.10.205:58013,10.10.10.205:58015");
# 创建数据库
use lg_resume;
# 创建集合
db.createCollection("lagou_resume_datas")
# 为数据库开启分片功能 
sh.enableSharding("lg_resume") 
# 为指定集合开启分片功能 
sh.shardCollection("lg_resume.lagou_resume_datas",{"id": hashed})
```

#### 安全认证配置

```shell
./bin/mongo --port 27017
# 创建管理员账号
use admin
db.createUser( {user:"root", pwd:"root", roles:[{role:"root",db:"admin"}] })
# 创建 lagou_gx 账号
use lg_resume
db.createUser( {user:"lagou_gx", pwd:"abc321", roles:[{role:"readWrite",db:"lg_resume"}] })


# 关闭mongo
#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

# 生成密钥文件
openssl rand -base64 756 > data/mongodb/mongoKeyFile.file 
# 修改权限
chmod 600 data/mongodb/mongoKeyFile.file

# 配置节点集群和分片节点集群 conf文件追加
auth=true 
keyFile=data/mongodb/mongoKeyFile.file

# 路由配置节点 conf文件追加
keyFile=data/mongodb/mongoKeyFile.file

```
