mongoDb的安装配置

原文： https://www.cnblogs.com/along21/p/10189072.html#auto_id_13

--------------------------------------------------------------

2.1 下载MongoDB

MongoDB 提供了 linux 各发行版本 64 位的安装包，你可以在官网下载安装包。

下载地址：https://www.mongodb.com/download-center#community，选择自己需要的版本

下载完安装包，并解压 tgz（以下演示的是 64 位 Linux上的安装）

（1）解压

[root@along ~]# cd /usr/local/ [root@along local]# tar -xzvf mongodb-linux-x86_64-4.0.5.tgz

（2）创建软连接，方便以后更换版本

[root@along local]# ln -s mongodb-linux-x86_64-4.0.5 mongodb

（3）配置环境变量

[root@along local]# vim /etc/profile.d/mongodb.sh

[root@along local]# cat /etc/profile.d/mongodb.sh

export MONGODB_HOME=/usr/local/mongodb

export PATH=$PATH:$MONGODB_HOME/bin

 [root@along local]# source /etc/profile.d/mongodb.sh

2.2 编写配置文件

（1）准备MongoDB所需的目录

[root@along ~]# cd /usr/local/mongodb

[root@along mongodb]# mkdir etc data log

[root@along mongodb]# touch log/mongod.log

（2）编写配置文件，借鉴gitlab 

[root@along mongodb]# vim etc/mongodb.conf

# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /usr/local/mongodb/mongod.log

# Where and how to store data.
storage:
  dbPath: /usr/local/mongodb/data
  journal:
    enabled: true
#  engine:
#  wiredTiger:

# how the process runs
processManagement:
  fork: true  # fork and run in background
  pidFilePath: /usr/local/mongodb/mongod.pid  # location of pidfile
  #timeZoneInfo: /usr/share/zoneinfo

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0  # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.

security:
  authorization: enabled

2.3 启动MongoDB

（1）使用命令启动MongoDB

[root@along mongodb]# mongod -f etc/mongodb.conf

[root@along mongodb]# mongod --shutdown -f /etc/mongodb.conf   ---关闭服务命令

[root@along mongodb]# ss -nutlp |grep 27017

tcp    LISTEN     0      128       *:27017                 *:*                   users:(("mongod",pid=12961,fd=11))

（2）将MongoDB设为开机自启

[root@along ~]# vim /etc/init.d/mongodb

#!/bin/bash

export MONGO_HOME=/usr/local/mongodb
#chkconfig:2345 20 90
#description:mongod
#processname:mongod
case $1 in
          start)
              $MONGO_HOME/bin/mongod --config $MONGO_HOME/etc/mongodb.conf
              ;;
          stop)
              $MONGO_HOME/bin/mongod  --shutdown --config $MONGO_HOME/etc/mongodb.conf
              ;;
          status)
              ps -ef | grep mongod
              ;;
          restart)
              $MONGO_HOME/bin/mongod  --shutdown --config $MONGO_HOME/etc/mongodb.conf
              $MONGO_HOME/bin/mongod --config $MONGO_HOME/etc/mongodb.conf
              ;;
          *)
              echo "require start|stop|status|restart"
              ;;
esac

[root@along ~]# chmod +x /etc/init.d/mongodb

[root@along ~]# chkconfig --add /etc/init.d/mongodb

可以使用systemctl 启动关闭MongoDB服务器

[root@along ~]# systemctl start mongodb

[root@along ~]# systemctl stop mongodb
