先检查yum源是否可用。
1 两台主机配置selinux
vim /etc/sysconfig/selinux
setenforce 1
getenforce
2 两台主机配置防火墙对ssh的限制
firewall-config
permanent
rich rule
family=ipv4
element=service ssh
action=accept
source：172.25.0.0/24
rich rule
family=ipv4
element=service ssh
action=reject
with type=icmp-host-prohibited
source：172.17.10.0/24
options=reload firewall
3 配置IPv6地址
nmcli connection modify eth0 ipv6.addresses fddb:fe2a:ab1e::c0a8:2/64 ipv6.method manual
nmcli connection up eth0
ip addr
ping6 fddb:fe2a:ab1e::c0a8:1
ping 172.25.0.11
4 配置链路聚合==============ping不通是正常的？？？
nmcli connection add con-name team0 ifname team0 autoconnect yes type team config '{"runner":{"name":"activebackup"}}'
nmcli connection add con-name team0-1 ifname eth2 type team-slave master team0
nmcli connection add con-name team0-2 ifname eth3 type team-slave master team0
nmcli connection show
nmcli connection modify team0 ipv4.addresses 192.168.0.101/24 ipv4.method manual
nmcli connection up team0
ip addr
ping 192.168.0.102
5 自定义用户环境
alias qstat='/bin/ps -Ao pid,tt,user,fname,rsz'
qstat
vi /etc/profile
vi /etc/bashrc
unalias qstat
source /etc/profile
qstat
unalias qstat
source /etc/bashrc
qstat
6 配置本地邮件服务
yum -y install postfix
systemctl enable postfix
vi /etc/postfix/main.cf
165 mydestination =
116 inet_interfaces = loopback-only
316 relayhost = [classroom.example.com]
99 myorigin = $mydomain
83 mydomain = example.com
194 local_transport=error:only local transport
systemctl start postfix
systemctl status postfix
mail -s lihb student@classroom.example.com
tail /var/log/maillog
firefox
7 配置端口转发
firewall-config
permanent
rich rule
family=ipv4
element=forward-port 5423/tcp>80
source=172.25.0.0/24
rich rule
family=ipv4
element=forward-port 5423/udp>80
source=172.25.0.0/24
options=reload firewall

setfacl -m u:brian:rwx /common/
ll -Zd /common/
semanage fcontext -a -t samba_share_t '/common(/.*)?'
restorecon -Rvv /common/
ll -Zd /common/
smbpasswd -a rob
smbpasswd -a brian
vim /etc/samba/smb.conf
89 workgroup = STAFF
94 interfaces = lo eth0 172.25.0.11/24
321 [common]
322 path = /common
323 writable = yes
324 browseable = yes
325 hosts allow = 172.25.0.
systemctl start smb
systemctl start nmb
systemctl status smb
systemctl status nmb
9 配置多用户SMB挂载
yum -y install samba-client cifs-utils
ll -d /mnt/multiuser
mkdir /mnt/multiuser
vi /etc/fstab
//172.25.0.11/common /mnt/multiuser cifs defaults,username=brian,password=redhat,sec=ntlmssp,multiuser 0 0
