1、建立samba共享，共享目录为/data，要求：（描述完整的过程）
1)共享名为shared，工作组为magedu；
2)添加组develop，添加用户gentoo,centos和ubuntu，其中gentoo和centos以develop为附加组，ubuntu不属于develop组；密码均为用户名；
3)添加samba用户gentoo,centos和ubuntu，密码均为“mageedu”；
4)此samba共享shared仅允许develop组具有写权限，其他用户只能以只读方式访问；
5)此samba共享服务仅允许来自于172.16.0.0/16网络的主机访问；
SERVER端：
OS版本CentOS7
ip:192.168.150.137
安装samba服务
~]# yum install samba -y
创建用户及组
~]# groupadd develop
~]# useradd gentoo -G develop
~]# useradd centos -G develop
~]# useradd ubuntu
~]# echo "gentoo" | passwd –stdin gentoo
更改用户 gentoo 的密码 。
passwd：所有的身份验证令牌已经成功更新。
~]# echo "centos" | passwd –stdin centos
更改用户 centos 的密码 。
passwd：所有的身份验证令牌已经成功更新。
~]# echo "ubuntu" | passwd –stdin ubuntu
更改用户 ubuntu 的密码 。
passwd：所有的身份验证令牌已经成功更新。
添加samba用户：此用户必须是OS用户，但密码非为OS用户的密码，而是访问SAMBA服务的专用密码
~]# smbpasswd -a gentoo
New SMB password:
Retype new SMB password:
Added user gentoo.
~]# smbpasswd -a centos
New SMB password:
Retype new SMB password:
Added user centos.
~]# smbpasswd -a ubuntu
New SMB password:
Retype new SMB password:
Mismatch – password unchanged.
Unable to get new password.
~]# smbpasswd -a ubuntu
New SMB password:
Retype new SMB password:
Added user ubuntu.
创建需要共享的目录并授予权限
~]# mkdir /data
~]# ls -ld /data
drwxr-xr-x 2 root root 6 12月 20 21:34 /data
~]# chmod g+w /data/ 此时需要给develop的group添加组写权限，不然后续就算在配置文件中添加了写权限也没用
~]# chown .develop /data
~]# ls -ld /data
drwxrwxr-x 2 root develop 6 12月 20 21:34 /data
修改配置文档，配置文档路径为/etc/sabma/smb.conf
~]# cd /etc/samba/
samba]# ls
lmhosts smb.conf smb.conf.example
samba]# cp smb.conf{,.bak}
samba]# vim smb.conf
[global]
workgroup = SAMBA
security = user
passdb backend = tdbsam
printing = cups
printcap name = cups
load printers = yes
cups options = raw
host allow = 192.168.150.0/24 设定允许访问的网段
[homes]
comment = Home Directories
valid users = %S, %D%w%S
browseable = No
read only = No
inherit acls = Yes
[printers]
comment = All Printers
path = /var/tmp
printable = Yes
create mask = 0600
browseable = No
[print$]
comment = Printer Drivers
path = /var/lib/samba/drivers
write list = root
create mask = 0664
directory mask = 0775
[shared] 设定共享名
comment = data
path= /data/ 共享目录
public = no 是否是公开的服务
valid users = gentoo,centos,ubuntu,@develop 授权用户
read list = ubuntu 定义只读用户
write list = @develop 定义可写用户组
注意：writable和write list不应该同时使用；
开启samba服务
samba]# systemctl start smb.service
samba]# ss -tnpl

client端测试
安装samba-client
~]# yum -y install samba-client
访问测试：
centos用户可读写
~]# smbclient //192.168.150.137/shared -U centos
Enter centos's password:

2、搭建一套文件vsftp文件共享服务，共享目录为/ftproot,要求：（描述完整的过程）
1)基于虚拟用户的访问形式；
2)匿名用户只允许下载，不允许上传；
3)禁锢所有的用户于其家目录当中；
4)限制最大并发连接数为200:；
5)匿名用户的最大传输速率512KB/s
6)虚拟用户的账号存储在mysql数据库当中。
7)数据库通过NFS进行共享。
环境介绍：
192.168.150.138
OS:CentOS 7
提供服务：NFS，mariadb的数据存放
192.168.150.137
OS:CentOS 7
提供服务：vsftp mariadb
192.168.150.136
OS:CentOS 6
client
NFS配置
192.168.150.138，NFS服务器端配置
安装nfs-utils
~]# yum -y install nfs-utils
创建提供NFS服务的目录
~]# mkdir -p /data
~]# chmod 777 /data
修改配置文件
~]# vim /etc/exports
/data 192.168.150.0/24(rw,no_root_squash) 此处需要注意一定要及no_root_squash选项，给共享文件夹授予对方root的权限，不然开启mysql是由于无法修改文件夹属组而无法开启
~]# exportfs -r
~]# systemctl start nfs.service
~]# ss -tnl nsf服务的端口为2049
