兩臺電腦都要進行的操作
禁止訪問域
yum install iptables-services
systemctl stop firewalld
disable
mask
systemctl start iptables
enable
iptables -F
-A INPUT -s 192.168.1.0/24 -j REJECT
service iptables save
自定義命令 兩臺都要作
vim /etc/bashrc
alias qstat=''
即可 qstat
或者 echo "alias qstat='/bin/ps -Ao pid,tt,user,fname,rsz'" >> /etc/bashrc
source /etc/bashrc
保存
80
yum install httpd
start enbable httpd
iptables -t nat -nL查詢nat表
端口轉換
進來時候路由前
iptables -t nat -A PREROUTING -s 172.25.0.0/24 -p tcp --dport 5423 -j DNAT --to-dest :80
把5423轉換到80端口
service iptables save
systemctl restart iptables 重啓測試一下
鏈路劇荷
自己添加兩塊網卡（共計三個） 如果沒有網卡的話
兩臺都要作
nmcli connection add con-name team0 type team config '{"runner":{"name":"activebackup"}}' ip4 172.16.0.75/24
nmcli connection add ifname eth2 con-name eth2 type team-slave master team0
更改ipv6
如果不能改 將 IPV6INIT=yes
nmcli connection modify eth0 ipv6.addresses ..../64
nmcli connection modify eth0 ipv6.method maunal
nmcli connection up 'System eth0'
兩個主機都要農
配置郵件服務 默認端口25
vim /etc/postfix/main.cf
75行 myhostname = desktop1.example.com 發送者
mydomain = example.com
myorigin = $mydomain 郵件結尾 看考試要求 要域名還是主機名結尾
317 relayhost = classroom.example.com 接受者
systemctl enable restart postfix.service
測試 mail hal .結束

配置samba
server
yum install samba samba-client samba-common -y
start enable smb nmb
mkdir /groupdir
semanage fcontext -a -t samba_share_t '/groupdir(/.*)?'
restorecon -RvvF /groupdir
useradd -s /sbin/nologin/ barney
smbpasswd -a barney
vim /etc/samba/smb.conf
workgroup = STAFF
[common]
path=/groupdir
browseable =yes
host allow = 172.25.1.
systemctl restart smb nmb
客戶
yum install -y smb-client
smbclient -L //172.25.1.11 -U barney
smbclient //172.25.1.11/common -U barney
多用戶掛載
server
mkdir /data
semanage fcontext -a -t samba_share_t '/data(/.*)?'
restorecon -RvvF /data
useradd -s /sbin/nologin manager
useradd -s /sbin/nologin wolferyne
smbpasswd -a manager
smbpasswd -a wolferyne
vim /etc/smb/smb.conf
[data]
path=/data
writeable =yes
host allow = 172.25.1.
write list = wolferyne
chmod o+w /data/
systemctl restart smb.service
測試下權限o+w
mount -o username=wolferne,password=westos //172.25.1.11/data /mnt
mkdir /mnt/1
mount -o username=manager,password=westos //172.25.1.11/data /mnt
mkdir /mnt/2 發現不幸
