[root@DY-ubuntu-01 nginx]#docker build -t ubuntu_nginx:v1.0 .
3、搭建harbor
#192.168.100.215、192.168.100.216都执行:
#准备harbor安装脚本，脚本参照：https://blog.51cto.com/dayu/5787187
[root@DY-ubuntu-06 ~]#bash install_harbor.sh   
[root@DY-ubuntu-05 ~]#vim /etc/docker/daemon.json

{
  "registry-mirrors": ["https://pgavrk5n.mirror.aliyuncs.com"],
  "insecure-registries": ["192.168.100.215","192.168.100.216","harbor.wang.org"]
}
[root@DY-ubuntu-05 ~]#systemctl restart docker
[root@DY-ubuntu-05 ~]#vim /etc/hosts
192.168.100.217 harbor.wang.org

[root@DY-ubuntu-05 ~]#vim /apps/harbor/harbor.yml
hostname: 192.168.100.215       #改为本机IP
[root@DY-ubuntu-05 ~]#cd /apps/harbor/
[root@DY-ubuntu-05 harbor]#./prepare
[root@DY-ubuntu-05 harbor]#docker-compose down
[root@DY-ubuntu-05 harbor]#docker-compose up -d

#浏览器分别登陆215和216设置harbor复制规则，具体请参照https://blog.51cto.com/dayu/5786146
4、nginx反向代理harbor

[root@DY-ubuntu-07 certs]#openssl x509 -req -days 3650 -in harbor.wang.org.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out harbor.wang.org.crt
[root@DY-ubuntu-07 certs]#cat harbor.wang.org.crt ca.crt > harbor.wang.org.pem
[root@DY-ubuntu-07 certs]#cd
[root@DY-ubuntu-07 ~]#vim /apps/nginx/conf/conf.d/harbor.wang.org.conf 

upstream harbor {
    hash $remote_addr;
    server 192.168.100.215;
    server 192.168.100.216;
}

server {
    listen 80;
    server_name harbor.wang.org;
    return 302 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    ssl_certificate /apps/nginx/conf/certs/harbor.wang.org.pem;
    ssl_certificate_key /apps/nginx/conf/certs/harbor.wang.org.key;

    mv jpress-v5.0.2.war ROOT.war && \
    groupadd -g 808 -r tomcat && \
    useradd -u 808 -g tomcat -M -r tomcat && \
    chown -R tomcat.tomcat /data/jpress/ /usr/local/tomcat/

CMD ["/usr/local/tomcat/bin/run_tomcat.sh"]

[root@DY-ubuntu-01 jpress]#ls

   MASTER_CONNECT_RETRY=10;


mysql> start slave;
mysql> show slave status\G
7、Jpress连接数据库
#数据库（192.168.100.213）：
mysql> create database jpress;
mysql> create user jpress@'192.168.100.%' identified by '123456';
mysql> grant all on jpress.* to jpress@'192.168.100.%';

[root@node3 ~]# route add -host 192.168.100.88 dev lo:0
12、部署防火墙
#firewalld（192.168.100.219）：
[root@DY-ubuntu-09 ~]#iptables -t nat -A PREROUTING -d 172.20.0.246 -p tcp --dport 80 -j DNAT --to-destination 192.168.100.88:80

[root@DY-ubuntu-09 ~]#echo 1 > /proc/sys/net/ipv4/ip_forward

[root@DY-ubuntu-09 ~]#iptables  -S -t nat
-P PREROUTING ACCEPT
-P INPUT ACCEPT
-P OUTPUT ACCEPT
-P POSTROUTING ACCEPT
-A PREROUTING -d 172.20.0.246/32 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.100.88:80

#keepalived和nginx反向代理服务器需要把默认路由指向防火墙（192.168.100.111-114）
[root@node3 ~]# route del default 
[root@node3 ~]# route add default gw 192.168.100.219 dev eth0
[root@node3 ~]# route -n
13、部署客户端路由
#10.0.0.101：
[root@ubuntu2004 ~]#echo 1 > /proc/sys/net/ipv4/ip_forward

[root@ubuntu2004 ~]#iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -j MASQUERADE 

[root@ubuntu2004 ~]#iptables -S -t nat
-P PREROUTING ACCEPT
-P INPUT ACCEPT
-P OUTPUT ACCEPT
-P POSTROUTING ACCEPT
-A POSTROUTING -s 10.0.0.0/24 -j MASQUERADE
14、部署DNS
# DNS（10.0.0.28）:
[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    10.0.0.28
jpress     A    172.20.0.246
wordpress  A    172.20.0.246
kodbox     A    172.20.0.246

[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

[root@rocky8 named]#route del default 
[root@rocky8 named]#route add default gw 10.0.0.101 dev eth0
15、客户端测试
#10.0.0.199：
[root@rocky9 ~]#route del default 
[root@rocky9 ~]#route add default gw 10.0.0.101 dev eth0
[root@rocky9 ~]#curl wordpress.wang.org -kL
[root@rocky9 ~]#curl kodbox.wang.org -kL
[root@rocky9 ~]#curl jpress.wang.org -kL
