實(shí)驗(yàn)鏡像：Centos 8.1.1911 草圖：（待補(bǔ)） 1、兩個(gè)real server 安裝配置 在keepalived Master上測(cè)試無(wú)問(wèn)題。 [root@HA1 ~]# curl http://192.168.94.140 this is real 1 server [root@HA1 ~]# curl http://192.168.94.141 this is real 2 server [root@HA1 ~]# 2、安裝keepalived、ipvsadm
使用keepalived即可完成real server的添加。 配置文件在/etc/keepalived下 [root@HA1 keepalived]# pwd /etc/keepalived [root@HA1 keepalived]# ls keepalived.conf [root@HA1 keepalived]# cp keepalived.conf keepalived.conf.bak [root@HA1 keepalived]# echo "" > keepalived.conf [root@HA1 keepalived]# 3、keepalived文件配置 MASTER ! Configuration File for keepalived
# 全局
global_defs {
notification_email {
root@localhost
}
notification_email_from keepalived@server.com
smtp_connect_timeout 3
smtp_server 127.0.0.1
router_id LVS_DEVEL
}
# 一個(gè)keepalived服務(wù)器,MASTER為主的進(jìn)行服務(wù)提供
vrrp_instance VI_1 {
interface ens33
state MASTER
priority 101
virtual_router_id 51
garp_master_delay 1
authentication {
auth_type PASS
auth_pass password
}
# VIP 地址
virtual_ipaddress {
192.168.94.200 dev ens33 label ens33:0
}
}
# VIP 關(guān)聯(lián)兩個(gè)real server
virtual_server 192.168.94.200 80 {
delay_loop 6
lb_algo rr
lb_kind DR
persistence_timeout 50
protocol TCP
# 兩個(gè)real server 都故障，提供服務(wù)的地址
sorry_server 192.168.94.138 80
# 定義real server 1
real_server 192.168.94.140 80 {
weight 1
# real server 存活檢測(cè)，檢測(cè)url的code
HTTP_GET {
url {
path /
status_code 200
}
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
}
}
# 定義real server 2
real_server 192.168.94.141 80 {
weight 1
HTTP_GET {

}
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
}
}
}
把配置文件復(fù)制到HA2上 BACKUP ! Configuration File for keepalived

1、高可用
2、real server 資源管理
我的配置文件可能有點(diǎn)問(wèn)題，測(cè)試的時(shí)候有些奇怪，有時(shí)間在檢查吧。 讀書(shū)和健身總有一個(gè)在路上 |
