题目:
主服务器192.168.244.130
防火墙允许服务的放行:
selinux放行
[root@localhost ~]# ll -Z /nfs/rhce
总用量 4
-rw-r--r--. 1 root root unconfined_u:object_r:default_t:s0 8 7月 10 16:52 index.html
-rw-r--r--. 1 nobody nobody system_u:object_r:default_t:s0 0 7月 11 19:55 test
[root@localhost ~]# ll -Z /var/www

[root@localhost ~]# chcon -t httpd_sys_content_t /nfs/rhce-R
[root@localhost ~]# ll -Z /nfs/rhce
总用量 4
-rw-r--r--. 1 root root unconfined_u:object_r:httpd_sys_content_t:s0 8 7月 10 16:52 index.html
-rw-r--r--. 1 nobody nobody system_u:object_r:httpd_sys_content_t:s0 0 7月 11 19:55 test
[root@localhost ~]# setenforce 1
编辑配置文件:(httpd的配置,利于域名访问与web内容的访问)
<directory /nfs/rhce>
allowoverride none
require granted
</directory><virtualhost 192.168.244.130>
documentroot /nfs/rhce
servername www.rhce.com
</virtualhost>
部署web服务在/nfs/rhce中,并且/nfs/rhce为共享目录及文件
[root@localhost /]# mkdir nfs
[root@localhost /]# ll
drwxr-xr-x. 2 root root 6 7月 10 16:41 nfs
[root@localhost /]# cd nfs/
[root@localhost nfs]# mkdir rhce
[root@localhost nfs]# echo i am ok > index.html
[root@localhost nfs]# cat index.html
i am ok
配置主服务器的主配置文件(此步骤为主从服务器的文件共享查看路径的连接/nfs)
重启服务并测试是否成功
[root@localhost ~]# systemctl restart nfs-server
[root@localhost ~]# systemctl restart rpcbind
[root@localhost ~]# showmount -e 192.168.244.130
Export list for 192.168.244.130:
/nfs/rhce 12.168.244.137
[root@localhost ~]#
配置本地解析地址:
[root@localhost conf.d]# vim /etc/hosts
192.168.244.130 www.rhce.com
[root@localhost conf.d]# curl www.rhce.com
i am ok
配置主服务器的dns
cd /etc/named.conf主配置文件
options {listen-on port 53 { 192.168.244.130; };directory "/var/named";
};
zone "rhce.com" IN {type master;file "named.rhce";
};
区域文件:cd /var/named/named.rhce,在重启服务
$TTL 1D
@ IN SOA @ admin.rhce.com. ( 01111)NS ns.rhce.com.
ns A 192.168.244.130
www A 192.168.244.130
ftp CNAME www
重启服务:systemctl restart named
测试dns实现:dig -t A www.rhce.com
从服务器(192.168.244.137)
防火墙打开,允许放行
[root@openEuler ~]# firewall-cmd --permanent --add-service=dns
success
[root@openEuler ~]# firewall-cmd --permanent --add-service=http
success
[root@openEuler ~]# firewall-cmd --permanent --add-service=nfs
success
[root@openEuler ~]# firewall-cmd --permanent --add-service=rpc-bind
success
[root@openEuler ~]# firewall-cmd --permanent --add-service=mountd
success
[root@openEuler ~]# firewall-cmd --reload
success
[root@openEuler ~]# firewall-cmd --list-service
dhcpv6-client dns http mdns mountd nfs rpc-bind ssh
开启selinux:setsebool -P httpd_use_nfs 1
设置dns的配置文件,在重启服务
[root@openEuler ~]# cat /etc/named.conf
options {
listen-on port 53 { 192.168.244.137; };directory "/var/named";
};
zone "rhce.com" IN {type slave;masters{ 192.168.244.130; };file "slaves/named.rhce";
};
[root@openEuler ~]# systemctl restart named
在测试是否能访问主服务器的文件
[root@openEuler ~]# curl www.rhce.com
i am ok
测试dns的成功:
判断是否能从服务器中去访问主服务器的文件
[root@openEuler ~]# showmount -e 192.168.244.130
Export list for 192.168.244.130:
/nfs/rhce 12.168.244.137
挂载文件
[root@openEuler ~]# mount 192.168.244.130:/nfs/rhce /haha
[root@openEuler ~]# ll /haha
total 4
-rw-r--r--. 1 root root 8 Jul 10 2024 index.html
[root@openEuler ~]# df -h /haha
Filesystem Size Used Avail Use% Mounted on
192.168.244.130:/nfs/rhce 70G 6.9G 64G 10% /haha
[root@openEuler ~]#
autofs的自动挂载
下载软件包:yum install autofs -y
在他的主配置编辑单独的目录:vim /etc/auto.master
在重启服务:systemctl restart autofs
[root@openEuler ~]# ll /haha/
total 0
[root@openEuler ~]# cd /haha
[root@openEuler haha]# ll
total 0
[root@openEuler haha]# cd nfs
[root@openEuler nfs]# ll
total 4
-rw-r--r--. 1 root root 8 Jul 10 2024 index.html
-rw-r--r--. 1 nobody nobody 0 Jul 11 2024 test#进入nfs后,此时此刻自动给你挂载了[root@openEuler nfs]# cd
[root@openEuler ~]# ll /haha
total 0
drwxrwxrwx. 2 root root 36 Jul 11 2024 nfs[root@openEuler ~]# df -h /haha
Filesystem Size Used Avail Use% Mounted on
/etc/auto.nfs 0 0 0 - /haha
[root@openEuler ~]#
最后关机重启,自动挂载
[root@openEuler ~]# cd /haha
[root@openEuler haha]# ll
total 0
[root@openEuler haha]# cd nfs
[root@openEuler nfs]# ll
total 4
-rw-r--r--. 1 root root 8 Jul 10 16:52 index.html
-rw-r--r--. 1 nobody nobody 0 Jul 11 19:55 test
[root@openEuler nfs]# cd
[root@openEuler ~]# ll /haha
total 0
drwxrwxrwx. 2 root root 36 Jul 11 19:55 nfs
[root@openEuler ~]# df -h
192.168.244.130:/nfs/rhce 70G 6.9G 64G 10% /haha/nfs
[root@openEuler ~]#
在主从服务器中所有服务要开机自启
[root@openEuler haha]# systemctl enable named
[root@openEuler haha]# systemctl enable rpcbind
[root@openEuler haha]# systemctl enable httpd
[root@openEuler haha]# systemctl enable nfs-server
[root@openEuler haha]#
