Liunx下安装mongodb步骤

https://www.mongodb.org/dl/linux/x86_64-suse11?_ga=2.49267750.1664716924.1521462220-1962063822.15208549661962063822.1520854966
1.从官网上下载跟系统对应的二进制包：mongodb-linux-x86_64-suse11-3.6.3.tgz（本人Linux是suse版本）

2.通过xftp工具上传到home目录下，进行解压，命令:tar -xzvf mongodb-linux-x86_64-suse11-3.6.3.tgz 

3.把解压后的文件夹名称改为mongodb，命令：mv mongodb-linux-x86_64-suse11-3.6.3  mongodb

4.进入mongodb目录，通过命令ls可以查看到存在一个bin目录（用来存放数据库的可执行文件）

5.创建文件夹：data，用来存放数据库的数据文件

6.创建文件夹：log，用来存放数据库的日志文件

7.创建文件夹：conf，用来存放数据库的配置文件,其中配置文件名为 mongodb.conf，内容为以下：
port = 27017
dbpath = data/
logpath = log/mongod.log 
directoryperdb = true
fork = true

8.在mongodb目录下执行命令：./bin/mongod -f ./conf/mongodb.conf ，就可通过配置文件启动mongdb,
  执行后出现以下信息说明已经成功启动的一个后台进程ID为18924的mongodb服务了
about to fork child process, waiting until server is ready for connections.
forked process: 18924
child process started successfully, parent exiting
9.执行命令：./bin/mongo，连接数据库，如下
  linux:/home/mongodb # ./bin/mongo
MongoDB shell version v3.6.3
connecting to: mongodb://127.0.0.1:27017
MongoDB server version: 3.6.3
Server has startup warnings:

10.在命令行上通过命令：use admin，切换到admin数据库，然后通过输入命令：
   db.createUser({user:"admin",pwd:"admin",roles:[{role:"userAdminAnyDatabase",db:"admin"}]})，创建数据库用户管理员如下所示
   
> use admin
switched to db admin
> db.createUser({user:"admin",pwd:"admin",roles:[{role:"userAdminAnyDatabase",db:"admin"}]})
Successfully added user: {
"user" : "admin",
"roles" : [
{
"role" : "userAdminAnyDatabase",
"db" : "admin"
}
]
}
    > 
11.通过快捷键：ctr+c退出mongdb客户端连接，如下所示结果
> ^C
bye 
12.通过命令：lsof -i:27017，可以查看到PID为18924和监听端口为27017的mongod进程在后台运行
linux:/home/mongodb # lsof -i:27017
COMMAND   PID USER   FD   TYPE   DEVICE SIZE/OFF NODE NAME
mongod  18924 root   11u  IPv4 64974476      0t0  TCP localhost:27017 (LISTEN)

13.通过kill - 9 18924 把mongdb进程终止
linux:/home/mongodb # kill -9 18924

14.通过文件编辑命令：vim ./conf/mongodb.conf，在mongodb.conf文件最后一行加auth = true,并按下Esc键和输入:wq,保存退出，
   mongodb.conf文件完整内容如下 
    port = 27017
dbpath = data/
logpath = log/mongod.log 
directoryperdb = true
fork = true
auth = true

15.通过命令./bin/mongod -f ./conf/mongodb.conf ，以开启权限认证方式启动
linux:/home/mongodb # ./bin/mongod -f ./conf/mongodb.conf 
about to fork child process, waiting until server is ready for connections.
forked process: 19426
