02.MongoDB单实例的部署

一、MongoDB单实例的部署

## 操作系统环境介绍

[root@node31 ~]# cat /etc/redhat-release;uname -r;uname -m;
CentOS Linux release 7.5.1804 (Core)
3.10.0-862.el7.x86_64
x86_64
[root@node31 ~]# firewall-cmd --state                          ## 查看firewall墙的状态
not running
[root@node31 ~]# free -h                                       ## 查看当前系统可用的内容
			  total        used        free      shared  buff/cache   available

[root@node31 ~]# ifconfig ens33|awk -F " " 'NR==2{print $2}'     ## 外网IP地址

[root@node31 ~]# ifconfig ens34|awk -F " " 'NR==2{print $2}'     ## 内网IP地址
172.16.1.31

## 软件及实例部署规划

/data/apps                  # 该目录下安装mongodb软件,安装后就是/data/apps/mongodb
/data/mongodb/6379          # 该目录下部署mongodb 27017实例
  /data/mongodb/27017/conf  # 存放mongodb 27017实例的配置文件
  /data/mongodb/27017/data  # 存放mongodb 27017实例的持久化数据
  /data/mongodb/27017/logs  # 存放mongodb 27017实例的日志文件
  /data/mongodb/27017/run   # 存放mongodb 27017实例的pid和socket文件

## MongoDB软件的安装

## 创建mongodb用户(需要设置密码,需要远程登录,需要有家目录,不要让其用户和密码过期)
[root@node31 ~]# chattr -i /etc/passwd /etc/shadow /etc/group /etc/gshadow
[root@node31 ~]# useradd mongodb
[root@node31 ~]# echo "mongodb"|passwd --stdin mongodb
Changing password for user mongodb.
passwd: all authentication tokens updated successfully.
[root@node31 ~]# chattr +i /etc/passwd /etc/shadow /etc/group /etc/gshadow
 
## 创建软件安装的目录
[root@node31 ~]# mkdir /data/apps
[root@node31 ~]# ls -ld /data/apps/
drwxr-xr-x 3 root root 62 Feb 21 10:19 /data/apps/ 
 
## 上传软件包准备安装
[root@node31 ~]# mkdir tools
[root@node31 ~]# cd tools/
[root@node31 tools]# rz
[root@node31 tools]# ll mongodb-linux-x86_64-rhel70-4.2.3.tgz
-rw-r--r-- 1 root root 132183978 Feb 21 10:16 mongodb-linux-x86_64-rhel70-4.2.3.tgz
[root@node31 tools]# tar xf mongodb-linux-x86_64-rhel70-4.2.3.tgz -C /data/apps/
[root@node31 tools]# ln -sv /data/apps/mongodb-linux-x86_64-rhel70-4.2.3/ /data/apps/mongodb
'/data/apps/mongodb' -> '/data/apps/mongodb-linux-x86_64-rhel70-4.2.3/'
[root@node31 ~]# chown -R mongodb:mongodb /data/apps/mongodb/
[root@node31 ~]# ls -ld /data/apps/mongodb/
drwxr-xr-x 3 mongodb mongodb 135 Feb 21 10:18 /data/apps/mongodb/
 
## 配置环境变量
[root@node31 ~]# ls -ld /data/apps/mongodb/bin/
drwxr-xr-x 2 mongodb mongodb 231 Feb 21 10:18 /data/apps/mongodb/bin/
[root@node31 ~]# echo "PATH=/data/apps/mongodb/bin:$PATH" >>/etc/bashrc
[root@node31 ~]# source /etc/bashrc
[root@node31 ~]# which mongod
/data/apps/mongodb/bin/mongod
[root@node31 ~]# mongod --version
