MongoDB 3.2 Shard Deployment steps

#linux Network optimization 1. File in/etc/sysctl.conf, join
Net.core.somaxconn = 2048
Fs.file-max = 2000000
Fs.nr_open = 2000000
Net.ipv4.ip_local_port_range = 1024 65535

• Hard Nofile 1000000
• Soft Nofile 1000000

2. 文件/etc/security/limits.conf中加入:

• Hard Nproc 1000000
• Hard Nproc 1000000

  3. Optimization of the MONGO section
  Echo Never >/sys/kernel/mm/transparent_hugepage/enabled
  echo Never >/sys/kernel/mm/transparent_hugepage/defrag

1. Disable Senux
   /etc/selinux/config
   Selinux=disabled

1. Firewall section, temporarily stop FIREWALLD
   Firewall
   Systemctl Start Firewalld.service #启动firewall
   Systemctl Stop Firewalld.service #停止firewall
   Systemctl Disable Firewalld.service #禁止firewall开机启动

1. MongoDB Installation
   If the decompression is installed, the default is put to/tools
   1. Unzip to
   /root/tools/mongodb
   CD/
   Ln-s/root/tools

   2. Join path
   Vim/etc/profile
   Export path= $PATH:/tools/mongodb/bin

   For RPM packages, run the following command
   RPM-IVH *.rpm

1. Configure MongoDB
   Mkdir/data/mongodb
   Cd/data/mongodb
   mkdir DB Log

   Common configuration file and start
   Mongod--config configdb.conf

=====================================
https://docs.mongodb.org/manual/tutorial/deploy-shard-cluster/

1. Configuration Instructions
   234 on the machine:
   Shard0 192.168.1.234:27018
   Shard1 192.168.1.234:27019
   Configsrv 192.168.1.234:30001

1. Configure Configserver
   1. Examples of file configurations
   Sharding:
   Clusterrole:configsvr
   Replication
   Replsetname:configreplset
   Net
   Port: <port>
   Storage
   DBPath: <path>

   2. Start
   Mongod--config configsrv1.conf
   Non-file mode
   Mongod--configsvr--replset configreplset--port <port>--dbpath <path>

1. Initialize Configserver, configure two configure here
   1. Enter MONGO Shell
   MONGO 192.168.1.234:30001
   Rs.initiate ({
   _id: "Configreplset",
   Configsvr:true,
   Members: [{_id:0, Host: ' 192.168.1.55:30001 '}, {_id:1, Host: ' 192.168.1.234:30001 '}
   ]
   } )

   2. View status
   Rs.status ()

2. Start MONGOs
   MONGOs--configdb configreplset/192.168.1.55:30001,192.168.1.234:30001--port 37017&
   MONGOs--configdb configrs/192.168.1.234:30001--port 37017--logappend--logpath/data/mongodb/log/route.log&

1. Connect to MONGOs
   MONGO--host 192.168.1.234--port 37017

1. Add sharding
   1. Create an example
   mkdir DB2 DB3
   Modify the corresponding configuration file
   Note: This place needs to set the maximum memory
   Ulimit-v 10000000 Modify maximum virtual address space to 10G
   --WIREDTIGERCACHESIZEGB 5

   2. Adding shards
   Sh.addshard ("rs1/192.168.1.234:27018")//Add a shard for a replica set named Rs1
   Sh.addshard ("192.168.1.234:27018")
   Sh.addshard ("192.168.1.234:27019")

   3. Activating shards
   Sh.enablesharding ("<database>")//Db.runcommand ({enablesharding: <database>})
   Sh.enablesharding ("MyDB")

   4. View status
   Sh.status ()

#########################
Pre-insertion Preparation
Sh.enablesharding ("<database>")//Db.runcommand ({enablesharding: <database>})
Sh.enablesharding ("Gwgps")

Db.location.ensureIndex ({"HostID": 1})
Db.location.ensureIndex ({"Postime": 1})

Sh.shardcollection ("Gwgps.location", {"HostID": 1})
