0.目的
下载MongoDB并安装，设置密码访问。
MongoDB官网会下载以下三个安装包
MongoDB-org-server-4.2.2-1.el6.x86_64.rpm #MongoDB的服务，配置文件，启动脚本
MongoDB-org-shell-4.2.2-1.el6.x86_64.rpm #包含mongo操作相关的shell命令
MongoDB-org-tools-4.2.2-1.el6.x86_64.rpm #对MongoDB进行备份，分析的工具集

1.安装server

# rpm -ivh MongoDB-org-server-4.2.2-1.el6.x86_64.rpm
# /etc/init.d/mongod start
starting mongod: [OK]

2.安装命令行用来登录MongoDB

# rpm -ivh MongoDB-org-shell-4.2.2-1.el6.x86_64.rpm
# mongo
> show dbs;
admin 0.000GB
config 0.000GB
local 0.000GB

3.设置MongoDB的管理员密码

> use admin
switched to db admin
> db.createUser({ user: "admin", pwd: "test123", roles: [{ role: "userAdminAnyDatabase", db: "admin" }] })
Successfully added user: {
"user" : "admin_root",
"roles" : [
{
"role" : "userAdminAnyDatabase",
"db" : "admin"
}
]
}
##验证登录，如果返回1，则证明密码生效
> db.auth("admin", "test123")
1

4.创建一个db库test，并分配账号和密码****

#登录管理员
> use admin
> db.auth("admin","test123")
#创建test库
> use test
> db.createUser({ user: "test", pwd: "test123", roles: [{ role: "dbOwner", db: "test" }] })
Successfully added user: {
"user" : "test",
"roles" : [
{
"role" : "dbOwner",
"db" : "test"
}
]
}

#程序调用以下链接即可：MongoDB://test:test123@localhost/test

运维中无法启动的一些故障
1.服务restart后，会出现无法开启的问题，查找日志如下

# /etc/init.d/mongod start
starting mongod: [FAILED]

# tail -f /var/log/mongdb/mongod.log
