1、建立samba共享，共享目錄為/data，要求：（描述完整的過程）
1)共享名為shared，工作組為magedu；
2)添加組develop，添加用戶gentoo,centos和ubuntu，其中gentoo和centos以develop為附加組，ubuntu不屬于develop組；密碼均為用戶名；
3)添加samba用戶gentoo,centos和ubuntu，密碼均為“mageedu”；
4)此samba共享shared僅允許develop組具有寫權限，其他用戶只能以只讀方式訪問；
5)此samba共享服務僅允許來自于172.16.0.0/16網絡的主機訪問；
SERVER端：
OS版本CentOS7
ip:192.168.150.137
安裝samba服務
~]# yum install samba -y
創建用戶及組
~]# groupadd develop
~]# useradd gentoo -G develop
~]# useradd centos -G develop
~]# useradd ubuntu
~]# echo "gentoo" | passwd –stdin gentoo
更改用戶 gentoo 的密碼 。
passwd：所有的身份驗證令牌已經成功更新。
~]# echo "centos" | passwd –stdin centos
更改用戶 centos 的密碼 。
passwd：所有的身份驗證令牌已經成功更新。
~]# echo "ubuntu" | passwd –stdin ubuntu
更改用戶 ubuntu 的密碼 。
passwd：所有的身份驗證令牌已經成功更新。
添加samba用戶：此用戶必須是OS用戶，但密碼非為OS用戶的密碼，而是訪問SAMBA服務的專用密碼
~]# 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.
創建需要共享的目錄并授予權限
~]# mkdir /data
~]# ls -ld /data
drwxr-xr-x 2 root root 6 12月 20 21:34 /data
~]# chmod g+w /data/ 此時需要給develop的group添加組寫權限，不然后續就算在配置文件中添加了寫權限也沒用
~]# chown .develop /data
~]# ls -ld /data
drwxrwxr-x 2 root develop 6 12月 20 21:34 /data
修改配置文檔，配置文檔路徑為/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 設定允許訪問的網段

valid users = %S, %D%w%S
browseable = No
read only = No
inherit acls = Yes
[printers]
comment = All Printers
path = /var/tmp

create mask = 0600
browseable = No
[print$]
comment = Printer Drivers
path = /var/lib/samba/drivers
write list = root
create mask = 0664
directory mask = 0775
[shared] 設定共享名
comment = data
path= /data/ 共享目錄
public = no 是否是公開的服務
valid users = gentoo,centos,ubuntu,@develop 授權用戶
read list = ubuntu 定義只讀用戶
write list = @develop 定義可寫用戶組
注意：writable和write list不應該同時使用；
開啟samba服務
samba]# systemctl start smb.service
samba]# ss -tnpl

client端測試
安裝samba-client
~]# yum -y install samba-client
訪問測試：
centos用戶可讀寫
~]# smbclient //192.168.150.137/shared -U centos
Enter centos's password:

2、搭建一套文件vsftp文件共享服務，共享目錄為/ftproot,要求：（描述完整的過程）
1)基于虛擬用戶的訪問形式；
2)匿名用戶只允許下載，不允許上傳；
3)禁錮所有的用戶于其家目錄當中；
4)限制最大并發連接數為200:；
5)匿名用戶的最大傳輸速率512KB/s
6)虛擬用戶的賬號存儲在mysql數據庫當中。
7)數據庫通過NFS進行共享。
環境介紹：
192.168.150.138
OS:CentOS 7
提供服務：NFS，mariadb的數據存放
192.168.150.137
OS:CentOS 7
提供服務：vsftp mariadb
192.168.150.136
OS:CentOS 6
client
NFS配置
192.168.150.138，NFS服務器端配置
安裝nfs-utils
~]# yum -y install nfs-utils
創建提供NFS服務的目錄
~]# 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) 此處需要注意一定要及no_root_squash選項，給共享文件夾授予對方root的權限，不然開啟mysql是由于無法修改文件夾屬組而無法開啟
~]# exportfs -r
~]# systemctl start nfs.service
~]# ss -tnl nsf服務的端口為2049

安裝編譯安裝所需包
~]#yum -y groupinstall "Development Tools" "Server Platform Develoment"
安裝mysql，及相關包
~]# yum -y install mariadb-server mariadb-devel openssl-devel pam-devel
pam_mysql的編譯安裝
~]# tar xf pam_mysql-0.7RC1.tar.gz
~]# cd pam_mysql-0.7RC1

pam_mysql-0.7RC1]# ls /lib64/security/ |grep pam_mysql 查看編譯安裝后pam_mysql.so是否存在
pam_mysql.la
pam_mysql.so
初始化mysql配置文件，將數據庫文件指向nfs掛載目錄/data
~]#vim /etc/my.cnf
