MongoDB Shard Build

First, the environment

$ cat/etc/redhat-release CentOS Linux release 7.0.1406 (Core) $ uname-alinux zhaopin-2-201 3.10.0-123.el7.x86_64 #1 SMP Mon June 12:09:22 UTC x86_64 x86_64 x86_64 gnu/linux$ MONGO--versionmongodb Shell version:3.0.6

Second, configure Shard Server1. Create a Directory

$ sudo mkdir-p/data/mongodb/{data/{sh0,sh1},backup/{sh0,sh1},log/{sh0,sh1},conf/{sh0,sh1}}

2. Preparing the configuration file

First Shard:

$ sudo vim/data/mongodb/conf/sh0/mongodb.conf# baseport = 27010maxConns = Filepermissions = 0700fork = Truenoauth = t Ruedirectoryperdb = Truedbpath =/data/mongodb/data/sh0pidfilepath =/data/mongodb/data/sh0/mongodb.pidoplogsize = 10journal = true# Securitynohttpinterface = truerest = false# Log LogPath =/data/mongodb/log/sh0/mongodb.loglogrotate = R Enamelogappend = trueslowms = 50replSet = Sh0 Shardsvr = True

A second shard:

$ sudo vim/data/mongodb/conf/sh1/mongodb.conf# baseport = 27011maxConns = Filepermissions = 0700fork = Truenoauth = t Ruedirectoryperdb = Truedbpath =/data/mongodb/data/sh1pidfilepath =/data/mongodb/data/sh1/mongodb.pidoplogsize = 10journal = true# Securitynohttpinterface = truerest = false# Loglogpath =/data/mongodb/log/sh1/mongodb.loglogrotate = re Namelogappend = trueslowms = 50replSet = Sh1shardsvr = True

3. Start Shard Server

$ sudo/opt/mongodb/bin/mongod--config/data/mongodb/conf/sh0/mongodb.confabout to fork child process, waiting until Ser Ver is ready for connections.forked Process:41492child process started successfully, parent exiting$ Sudo/opt/mongodb/bi N/mongod--config/data/mongodb/conf/sh1/mongodb.confabout to fork child process, waiting until server was ready for Connec Tions.forked Process:41509child Process started successfully, parent exiting$ PS aux | grep MONGO | Grep-v greproot     41492  0.5  0.0 518016 54604?

Third, configure Config Server1. Create a Directory

$ sudo mkdir-p/data/mongodb/{data/{cf0,cf1,cf2},backup/{cf0,cf1,cf2},log/{cf0,cf1,cf2},conf/{cf0,cf1,cf2}}

2. Preparing the configuration file

First Configuration server:

$ sudo vim/data/mongodb/conf/cf0/config.conf# baseport = 27000maxConns = 800filePermissions = 0700fork = Truenoauth = Tru Edirectoryperdb = Truedbpath =/data/mongodb/data/cf0pidfilepath =/data/mongodb/data/cf0/config.pidoplogsize = 10journal = true# Securitynohttpinterface = truerest = false# Loglogpath =/data/mongodb/log/cf0/config.loglogrotate = ren Amelogappend = Trueslowms = 50configsvr = True

A second configuration server:

$ sudo vim/data/mongodb/conf/cf1/config.conf# baseport = 27001maxConns = 800filePermissions = 0700fork = Truenoauth = Tru Edirectoryperdb = Truedbpath =/data/mongodb/data/cf1pidfilepath =/data/mongodb/data/cf1/config.pidoplogsize = 10journal = true# Securitynohttpinterface = truerest = false# Loglogpath =/data/mongodb/log/cf1/config.loglogrotate = ren Amelogappend = Trueslowms = 50configsvr = True

A third configuration server:

$ sudo vim/data/mongodb/conf/cf2/config.conf# baseport = 27002maxConns = 800filePermissions = 0700fork = Truenoauth = Tru Edirectoryperdb = Truedbpath =/data/mongodb/data/cf2pidfilepath =/data/mongodb/data/cf2/config.pidoplogsize = 10journal = true# Securitynohttpinterface = truerest = false# Loglogpath =/data/mongodb/log/cf2/config.loglogrotate = ren Amelogappend = Trueslowms = 50configsvr = True

3. Start

Iv. Configuring query Routers1. Create a Directory

$ sudo mkdir-p/data/mongodb/{data/{ms0,ms1},backup/{ms0,ms1},log/{ms0,ms1},conf/{ms0,ms1}}

2. Preparing the configuration file

First Configuration server:

$ sudo vim/data/mongodb/conf/ms0/mongos.conf# baseport = 30000maxConns = 800filePermissions = 0700fork = Truepidfilepath =/data/mongodb/data/ms0/mongos.pid# Loglogpath =/data/mongodb/log/ms0/mongos.loglogrotate = Renamelogappend = Trueconfigdb = 172.30.2.201:27000,172.30.2.201:27001,172.30.2.201:27002

A second configuration server:

$ sudo vim/data/mongodb/conf/ms1/mongos.conf# baseport = 30000maxConns = Filepermissions = 0700fork = Truepidfilepath =/data/mongodb/data/ms1/mongos.pid# Log LogPath =/data/mongodb/log/ms1/mongos.loglogrotate = Renamelogappend = Trueconfigdb = 172.30.2.201:27000,172.30.2.201:27001,172.30.2.201:27002

V. Initializing a single-node replica set

The benefit of configuring a replica set is for high availability, configuring a single node is my own. To save time, the configuration of the Shard does not need to be modified, as is the case with subsequent additions to the node and replica set

Shard One:
