Centos7下安裝配置keepalived

這裡用的是兩台裝置做高可用

確認使用的網絡卡

在這裡使用第2個網絡卡enp0s3

安裝的方法有很多，我這裡用的是yum安裝

小技巧：檢視yum安裝的配置檔案在哪兒

keepalived.conf內部檔案解讀

vim /etc/keepalived/keepalived.conf

可以用d-g刪掉裡面多餘的資訊，只保留下面幾行就行

lb01配置資訊:

[root@lb01 ~]# cat /etc/keepalived/keepalived.conf

! configuration file for keepalived

global_defs

vrrp_instanceoldboy

virtual_ipaddress

}lb02配置資訊:

! configuration file for keepalived

global_defs

vrrp_instanceoldboy

virtual_ipaddress

}啟動服務：

service keepalived start

關閉keepalived服務
systemctl stop keepalived.service
# 配置開機自啟動
systemctl enable keepalived

檢視啟動日誌：

journalctl -xe

tail -f  /var/log/messages
