MongoDB-4.2.2安装并配置账户密码进行访问

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
