mongodb3.2安装与基本配置

一、使用yum安装mongodb 3.2

[root@node2 ~]# cat /etc/yum.repos.d/mongodb.repo
[mongodb-org-3.2]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.2/x86_64/
gpgcheck=0
enabled=1
[root@node2 ~]# yum install mongodb-org*
[root@node2 ~]# egrep -v "^(#|$)" /etc/mongod.conf
systemLog:
  destination: file
  logAppend: true
  path: /data/mongodb/log/mongod.log
storage:
  dbPath: /data/mongodb/data
  directoryPerDB: true
  journal:
    enabled: true
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /data/mongodb/conf/mongod.pid  # location of pidfile
net:
  port: 27027
  #bindIp: 127.0.0.1  # Listen to local interface only, comment to listen on all interfaces.
[root@node2 ~]# mkdir -p /data/mongodb/{conf,data,log} 
[root@node2 ~]# chown -R mongod.  /data/mongodb
[root@node2 ~]# tail /etc/security/limits.conf
# End of file
mongod soft nproc 40000
* hard nofile 1000000
* soft nofile 1000000
* soft core unlimited
* soft stack 10240
* - nofile 65535
push - nproc 65535
push - nofile 320000
work - nproc 10000
[root@node2 ~]# cat /etc/security/limits.d/90-nproc.conf
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.
*          soft    nproc     1024
root       soft    nproc     unlimited
[root@node2 ~]#
[root@node2 ~]# sed -n '62,64p' /etc/init.d/mongod
if [ -f /sys/kernel/mm/transparent_hugepage/defrag ] ; then
echo never > /sys/kernel/mm/transparent_hugepage/defrag
fi
[root@node2 ~]# service mongod  start

二、macbook pro 上安装mongodb

  参考： https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/

安装brew： /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew update

brew install mongodb

mongod  - -config /usr/local/etc/mongod.conf

三、mongo 客户端工具有： http://docs.mongodb.org/ecosystem/tools/administration-interfaces/

四、Cent0S7 上部署mongo3.6(补)

[root@meteor ~]#  echo "never" > /sys/kernel/mm/transparent_hugepage/defrag
[root@meteor ~]#  cat /etc/yum.repos.d/mongo.repo 
[mongodb-org-3.6]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.6/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.6.asc
[root@meteor ~]# yum install mongodb-org
[root@meteor ~]# mkdir -p /data/mongodb/{conf,data,logs,run}                                                                          
[root@meteor ~]# chown -R mongod.mongod /data/mongodb
[root@meteor ~]# vim /usr/lib/systemd/system/mongod.service
[root@meteor ~]# cat /usr/lib/systemd/system/mongod.service

[root@meteor ~]# 
[root@meteor ~]# systemctl daemon-reload
[root@meteor ~]# vim /etc/mongod.conf
[root@meteor ~]# grep -Pv "^( *#|$)" /etc/mongod.conf 
systemLog:
  destination: file
  logAppend: true
  path: /data/mongodb/logs/mongod.log
storage:
  dbPath: /data/mongodb/data/
  directoryPerDB: true
  journal:
    enabled: true
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /data/mongodb/run/mongod.pid  # location of pidfile
  timeZoneInfo: /usr/share/zoneinfo
net:
  port: 27027
security:
  authorization: enabled
  keyFile: /data/mongodb/conf/keyFile
[root@meteor ~]# 注：mongodb配置文件中的各路径一定要与systemd下mongod.service文件中的各路径设置一致，否则会导致无法启动或启动错误(返回值100)。
[root@meteor ~]# openssl rand -base64 755 >  /data/mongodb/conf/keyFile
[root@meteor ~]# cat /data/mongodb/conf/keyFile
