你想知道如何在Linux中配置DNS主从和LVS Keepalived后lamp服务。下面是一个简单的示例:
DNS主从配置
sudo apt-get install bind9/etc/bind/named.conf.options,添加以下内容:options {
directory "/var/cache/bind";
recursion yes;
allow-transfer { none; };
};
/etc/bind/named.conf.local,添加以下内容:zone "example.com" {
type slave;
masters { 192.168.1.100; };
file "/var/cache/bind/db.example.com";
};
sudo service bind9 restartLVS Keepalived配置
sudo apt-get install keepalived/etc/keepalived/keepalived.conf,添加以下内容:global_defs {
router_id LVS_DIR
}
vrrp_instance VRRP1 {
state MASTER
interface eth0
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 123456
}
}
virtual_server 192.168.1.100 80 {
delay_loop 3
lb_algo wrr
lb_kind DR
protocol TCP
real_server 192.168.1.101 80 {
weight 1
TCP_CHECK {
connect_port 80
connect_timeout 3
}
}
real_server 192.168.1.102 80 {
weight 1
TCP_CHECK {
connect_port 80
connect_timeout 3
}
}
}
sudo service keepalived restartlamp服务配置
sudo apt-get install lamp-server^/etc/apache2/apache2.conf,添加以下内容:<VirtualHost *:80>
ServerName example.com
DocumentRoot /var/www/html
</VirtualHost>
sudo service apache2 restart这些配置只是一个简单的示例,实际情况可能需要根据你的需求进行修改。
