[root@rocky-102 ~]# nginx -s reload
11、部署NFS+Nexus
#搭建NFS（192.168.100.107）:
[root@node07 ~]# vim /etc/exports
/data/jpress 192.168.100.0/24(rw,all_squash,anonuid=997,anongid=992)
/data/shopxo 192.168.100.0/24(rw,all_squash,anonuid=997,anongid=992)
[root@node07 ~]# exportfs -r
[root@node07 ~]# exportfs -v
[root@node07 ~]# systemctl restart nfs-server.service
[root@node07 ~]# yum install -y nfs-utils
=================================================================================
# jpress服务器（192.168.100.103、192.168.100.104）:
[root@node05 ~]# yum install -y rsync
[root@node03 ~]# rsync -av /data/jpress/ROOT/* root@192.168.100.107:/data/jpress/ #把现有的网站页面拷贝到nfs上，一台服务器执行即可
[root@node03 ~]# yum install -y nfs-utils
[root@node03 ~]# showmount -e 192.168.100.107
[root@node03 ~]# vim /etc/fstab
192.168.100.107:/data/jpress /data/jpress/ROOT nfs _netdev 0 0
[root@node03 ~]# mount -a
==============================================================================
# shopxo服务器(192.168.100.105、192.168.100.106)：
[root@node05 ~]# rsync -av /data/shopxo/public/static/upload/* root@192.168.100.107:/data/shopxo/ #把现有的网站页面拷贝到nfs上，一台服务器执行即可
[root@node05 ~]# yum install -y rsync
[root@node05 ~]# yum install nfs-utils
[root@node05 ~]# vim /etc/fstab
192.168.100.107:/data/shopxo /data/shopxo/public/static/upload nfs _netdev 0 0
==============================================================================
# 部署nexus
[root@node07 ~]# yum install java -y
[root@node07 ~]# tar xf nexus-3.41.1-01-unix.tar.gz -C /usr/local/
[root@node07 ~]# cd /usr/local/
[root@node07 local]# mv nexus-3.41.1-01/ nexus
[root@node07 local]# echo 'PATH=/usr/local/nexus/bin:$PATH' > /etc/profile.d/nexus.sh
[root@node07 local]# . /etc/profile.d/nexus.s
[root@node07 local]# vim nexus/bin/nexus.vmoptions

......
[root@node07 local]# nexus run

# 找一台电脑连接192.168.100.107:8081设置仓库即可12、部署lvs
# nginx2（192.168.100.102）：
[root@node02 ~]# ip a a 192.168.100.88/32 dev tunl0
[root@node01 ~]# ip link set up tunl0
[root@node02 ~]# echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
[root@node02 ~]# echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
[root@node02 ~]# echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore
[root@node02 ~]# echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
[root@node02 ~]# echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter
[root@node02 ~]# echo 0 > /proc/sys/net/ipv4/conf/tunl0/rp_filter # nginx2（192.168.100.101）：
[root@node01 ~]# ip a a 192.168.100.99/32 dev tunl0
[root@node01 ~]# ip link set up tunl0
[root@node01 ~]# echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore
[root@node01 ~]# echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
[root@node01 ~]# echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore
[root@node01 ~]# echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
[root@node01 ~]# echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter
[root@node01 ~]# echo 0 > /proc/sys/net/ipv4/conf/tunl0/rp_filter # LVS（192.168.100.108）： （因各个反向代理服务器只有一台，所以每个网站只设置一个IP，如果增加了反向代理服务器，在此多增加一个ip即可）
[root@node08 ~]# echo 1 > /proc/sys/net/ipv4/ip_forward #临时开启ip转发功能
[root@node08 ~]# yum install ipvsadm -y
[root@node08 ~]# ipvsadm -A -t 192.168.100.88:80 -s wrr
[root@node08 ~]# ipvsadm -a -t 192.168.100.88:80 -r 192.168.100.102:80 -i
[root@node08 ~]# ipvsadm -A -t 192.168.100.99:80
[root@node08 ~]# ipvsadm -a -t 192.168.100.99:80 -r 192.168.100.101:80 -i13、部署firewalld
# firewalld（192.168.100.109）：
[root@node09 ~]# echo 1 > /proc/sys/net/ipv4/ip_forward
[root@node09 ~]# iptables -t nat -A PREROUTING -d 172.20.0.32 -p tcp --dport 80 -j DNAT --to-destination 192.168.100.88:80
[root@node09 ~]# iptables -t nat -A PREROUTING -d 172.20.0.249 -p tcp --dport 80 -j DNAT --to-destination 192.168.100.99:80
[root@node09 ~]# iptables -t nat -nvL
# 这里就可以用172.20.0.0网段的主机测试下是否能访问jpress和shopxo，如果无法访问，把nginx反向代理的ssl禁用，如下：
upstream shopxo {
# hash $remote_addr;
server 192.168.100.105;
server 192.168.100.106;
}
server {
listen 80;
server_name shopxo.wang.org;
# return 302 https://$server_name$request_uri;
location / {
proxy_pass http://shopxo;
proxy_set_header host $http_host;
# proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
#server {
# listen 443 ssl http2;
# server_name shopxo.wang.org;
# ssl_certificate /etc/nginx/ssl/jpress.wang.org.pem;
# ssl_certificate_key /etc/nginx/ssl/jpress.wang.org.key;
# client_max_body_size 20m;
# location / {
# proxy_pass http://shopxo;
# proxy_set_header host $http_host;
# proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
# }
#}
14、部署客户路由器
#client-router（192.168.168.88）：
[root@client-router ~]#echo 1 > /proc/sys/net/ipv4/ip_forward
[root@client-router ~]#iptables -t nat -A POSTROUTING -s 192.168.168.0/24 -j MASQUERADE15、部署DNS
# DNS（192.168.168.100）:
[root@dns ~]# vim /etc/named.conf
// listen-on port 53 { 127.0.0.1; };
// listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
secroots-file "/var/named/data/named.secroots";
recursing-file "/var/named/data/named.recursing";
// allow-query { localhost; };
[root@dns ~]# vim /etc/named.rfc1912.zones
zone "wang.org" IN {
type master;
file "wang.org.zone";
};
[root@dns ~]# cd /var/named/
[root@dns named]# cp -p named.localhost wang.org.zone
[root@dns named]# vim wang.org.zone
$TTL 1D
@ IN SOA admin admin.wang.org. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS admin
admin A 192.168.168.100;
jpress A 172.20.0.249;
shopxo A 172.20.0.32;
[root@dns named]# named-checkconf #检查配置文件语法是否有问题，如果需要检查zone文件的语法是否有问题，需要安装上bind-utils
[root@dns named]# systemctl restart named
16、客户端测试
[root@rocky8 ~]#vim /etc/resolv.conf
nameserver 192.168.168.100
[root@rocky8 ~]#route -n
Kernel IP routing table
