CentOS7 安装 MongoDB

方法 1：RPM 包安装

• 访问官网页面下载 rpm 包

  https://www.mongodb.com/download-center/community

  # mongodb服务端
  wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/3.6/x86_64/RPMS/mongodb-org-server-3.6.14-1.el7.x86_64.rpm
  # mongodb 客户端连接工具 mongo
  wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/3.6/x86_64/RPMS/mongodb-org-shell-3.6.14-1.el7.x86_64.rpm
  # mongodb 工具集合：mongoimport, bsondump, mongodump, mongoexport, mongofiles, mongorestore, mongostat, mongotop
  wget https://repo.mongodb.org/yum/redhat/7/mongodb-org/3.6/x86_64/RPMS/mongodb-org-tools-3.6.14-1.el7.x86_64.rpm

• 安装 mongodb server

  yum install mongodb-org-server-3.6.14-1.el7.x86_64.rpm mongodb-org-tools-3.6.14-1.el7.x86_64.rpm mongodb-org-tools-3.6.14-1.el7.x86_64.rpm

• 设置远程访问

  修改/etc/mongod.conf文件bindIP部分

  net:
    port: 27017
    bindIp: 0.0.0.0

• 启动服务并开机自启

  systemctl restart mongod.service
  systemctl status mongod.service
  systemctl enable mongod.service

方法 2：两进制文件安装

• 下载二进制文件

  wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-3.6.14.tgz

• 安装依赖

  yum install libcurl openssl

• 创建 mongo 用户和组

  /usr/sbin/groupadd -r mongod
  /usr/sbin/useradd -M -r -g mongod -d /var/lib/mongo -s /bin/false -c mongod mongod

• 解压文件

  tar xvf mongodb-linux-x86_64-rhel70-3.6.14.tgz
  mv mongodb-linux-x86_64-rhel70-3.6.14 /opt/mongodb

• 配置环境变量

  echo '
  # MongoDB
  export PATH=$PATH:/opt/mongodb/bin
  ' >> /etc/profile
  source /etc/profile

• 创建配置文件

  创建/etc/mongod.conf文件,内容如下

  # where to write logging data.
  systemLog:
    destination: file
    logAppend: true
    path: /var/log/mongodb/mongod.log
  
  # Where and how to store data.
  storage:
    dbPath: /var/lib/mongo
    journal:
      enabled: true
  
  # how the process runs
  processManagement:
    fork: true  # fork and run in background
    pidFilePath: /var/run/mongodb/mongod.pid  # location of pidfile
    timeZoneInfo: /usr/share/zoneinfo
  
  # network interfaces
  net:
    port: 27017
    bindIp: 0.0.0.0

• 创建 log 目录和 dbPath 目录

  # log
  mkdir -p /var/log/mongodb/
  chown -R mongod:mongod /var/log/mongodb/
  # dbPath
  mkdir -p /var/lib/mongo
  chown -R mongod:mongod /var/lib/mongo

• 注册系统服务

  创建/lib/systemd/system/mongod.service文件，内容如下

  [Unit]
  Description=MongoDB Database Server
  Documentation=https://docs.mongodb.org/manual
  After=network.target
  
  [Service]
  User=mongod
  Group=mongod
  Environment="OPTIONS=-f /etc/mongod.conf"
  ExecStart=/opt/mongodb/bin/mongod $OPTIONS
  ExecStartPre=/usr/bin/mkdir -p /var/run/mongodb
  ExecStartPre=/usr/bin/chown mongod:mongod /var/run/mongodb
  ExecStartPre=/usr/bin/chmod 0755 /var/run/mongodb
  PermissionsStartOnly=true
  PIDFile=/var/run/mongodb/mongod.pid
  Type=forking
  # file size
  LimitFSIZE=infinity
  # cpu time
  LimitCPU=infinity
  # virtual memory size
  LimitAS=infinity
  # open files
  LimitNOFILE=64000
  # processes/threads
  LimitNPROC=64000
  # locked memory
  LimitMEMLOCK=infinity
  # total threads (user+kernel)
  TasksMax=infinity
  TasksAccounting=false
  # Recommended limits for for mongod as specified in
  # http://docs.mongodb.org/manual/reference/ulimit/#recommended-settings
  
  [Install]
  WantedBy=multi-user.target

• 重新加载 systemd

  systemctl daemon-reload

• 启动服务并设置开机自启

  systemctl restart mongod.service
  systemctl status mongod.service
  systemctl enable mongod.service
