LVS综合实验

1、环境准备

提前准备：Mysql8.0.30安装包、Mysql安装脚本、shopxo2.3.0安装包、DNS脚本

服务器 IP地址 作用 系统版本
Mysql-master 10.0.0.103 shopxo网站主数据库 Ubuntu2004
Mysql-slave 10.0.0.104 shopxo网站备份数据库 Ubuntu2004
NFS-data 10.0.0.105 shopxo图片视频等多媒体大文件存放NFS Ubuntu2004

shopxo1 10.0.0.101 shopxo1网站 Ubuntu2004
shopxo2 10.0.0.102 shopxo1备份网站 Ubuntu2004
LVS eth0:10.0.0.100
eth1:192.168.0.100		 LVS 负载网站访问调度 Ubuntu2004
client Route eth0:192.168.0.88
eth1:192.168.10.88		 客户端路由器 rocky8.6
DNS 192.168.10.100 域名解析 rocky8.6

2、搭建Mysql主服务器

# mysql-master:（提前脚本安装好mysql）
[root@mysql-master ~]#vim /etc/my.cnf      #更改配置文件
[mysqld]
server-id=104
log-bin
datadir=/data/mysql
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid
default_authentication_plugin=mysql_native_password      
gtid_mode=ON
enforce_gtid_consistency
[client]
socket=/data/mysql/mysql.sock
[root@mysql-master ~]#systemctl restart mysql
[root@mysql-master ~]#mysql -p123456
mysql> create user repluser@'10.0.0.%' identified by '123456';      #创建主从同步账号并授权
mysql> grant replication slave on *.* to repluser@'10.0.0.%';

mysql> create user shopxo@'10.0.0.%' identified by '123456';       #创建主从同步账号并授权
mysql> grant all on shopxo.* to shopxo@'10.0.0.%';

3、搭建Mysql从服务器

# mysql-slave： （提前脚本安装好mysql）
[root@ubuntu2004 ~]#vim /etc/my.cnf
[mysqld]
server-id=104
log-bin
datadir=/data/mysql
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid
default_authentication_plugin=mysql_native_password
gtid_mode=ON
enforce_gtid_consistency
[client]
socket=/data/mysql/mysql.sock
[root@ubuntu2004 ~]#systemctl restart mysql
[root@ubuntu2004 ~]#mysql -p123456
CHANGE MASTER TO
  MASTER_HOST='10.0.0.103',
  MASTER_USER='repluser',
  MASTER_PASSWORD='123456',
  MASTER_PORT=3306,
  MASTER_AUTO_POSITION=1;
  
mysql> start slave;

4、搭建nfs-backup服务器

## nfs-backup：
[root@nfs-backup ~]#apt install -y rsync
[root@nfs-backup ~]#vim /etc/rsyncd.conf
uid = root
gid = root  
max connections = 0
ignore errors
exclude = lost+found/
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
reverse lookup = no
[backup] 
path = /data/backup/  
comment = backup dir
read only = no 
auth users = rsyncuser  
secrets file = /etc/rsync.pas


[root@nfs-backup ~]#echo rsyncuser:123456 > /etc/rsync.pas
[root@nfs-backup ~]#chmod 600 /etc/rsync.pas
[root@nfs-backup ~]#mkdir /data/backup -p
[root@nfs-backup ~]#setfacl -m u:nobody:rwx /data/backup
[root@nfs-backup ~]#systemctl restart rsync.service 

# 105服务器nfs-data验证：
[root@nfs-data ~]#rsync rsyncuser@10.0.0.106::backup
Password: 
drwxr-xr-x          4,096 2022/09/07 20:18:38 .

[root@shopxo2 ~]#mount -a

8、ClientRoute

[root@Route ~]# iptables -t nat -A POSTROUTING -s 192.168.10.0/24 -j MASQUERADE
[root@Route ~]# echo 1 > /proc/sys/net/ipv4/ip_forward

9、搭建DNS服务器

[root@DNS ~]# yum install -y bind bind-utils
[root@DNS ~]# vim /etc/named.conf

#注释下面三行
//  listen-on port 53 { 127.0.0.1; };
//  listen-on-v6 port 53 { ::1; };
//  allow-query     { localhost; };

[root@DNS ~]# vim /etc/named.rfc1912.zones
zone "dayu.org" IN {
    type master;
    file "dayu.org.zone";
};

[root@DNS ~]# cp -p /var/named/named.localhost /var/named/dayu.org.zone
[root@DNS ~]# vim /var/named/dayu.org.zone
$TTL 1D
@   IN SOA wang rname.invalid. (
                    0   ; serial
                    1D  ; refresh
                    1H  ; retry
                    1W  ; expire
                    3H )    ; minimum
    NS  wang
wang    A   192.168.10.100
www     A   192.168.0.100

10、客户机测试

[root@client ~]# vim /etc/resolv.conf          #指向dns服务器
nameserver 192.168.10.100
[root@client ~]# curl www.dayu.org             #测试
