linux安装mongodb

启动mongodb服务

mongodb集成到asp .net Core Web Api项目(源码可下载)

1.安装依赖

yum install libcurl openssl

2.下载，解压

wget -c https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-4.0.5.tgz
tar -zxvf mongodb-linux-x86_64-4.0.5.tgz

3.移动mongodb

mkdir -p /usr/local/mongodb
mv mongodb-linux-x86_64-4.0.5/* /usr/local/mongodb

4.加入环境变量

vim /etc/profile
#下面代码加入文件末尾
PATH=$PATH:/usr/local/mongodb/bin
export PATH
#立刻生效
source /etc/profile
#查看版本
[root@jmsite ~]# mongod --version
db version v4.0.5
git version: 3739429dd92b92d1b0ab120911a23d50bf03c412
allocator: tcmalloc
modules: none
build environment:
    distarch: x86_64
    target_arch: x86_64

5.创建数据目录，日志目录，配置文件目录，进程文件目录

mkdir -p /usr/local/mongodb/data
mkdir -p /usr/local/mongodb/log
mkdir -p /usr/local/mongodb/conf
mkdir -p /var/run/mongodb

6.创建配置文件

vim /usr/local/mongodb/conf/mongodb.conf

写入以下配置

#监听端口
port = 27017
#数据库存文件存放目录
dbpath = /usr/local/mongodb/data
#日志文件存放路径
logpath = /usr/local/mongodb/log/mongodb.log
#进程文件存放路径
pidfilepath = /var/run/mongodb/mongodb.pid
#使用追加的方式写日志
logappend = true
#以守护进程的方式运行，创建服务器进程
fork = true
#最大同时连接数
maxConns = 100
#每次写入会记录一条操作日志
journal = true
#不绑定ip，这样就可外部访问了
bind_ip = 0.0.0.0
#校验权限
auth = true

7.创建一个不能登录的mongodb用户并设置权限

useradd mongodb -M -s /sbin/nologin
chown -R mongodb.mongodb /usr/local/mongodb
chown -R mongodb.mongodb /var/run/mongodb

8.创建启动脚本

vim /etc/init.d/mongod

写入以下配置

#!/bin/sh
#
# mongodb      init file for starting up the MongoDB server
#
# chkconfig:   - 90 10
# description: Starts and stops the MongDB daemon that handles all \
#              database requests.

# Source function library.
. /etc/rc.d/init.d/functions
