1
[root@haproxy1 keepalived]# scp keepalived.conf haproxy2:/etc/keepalived/
在haproxy2.daixiang.com上修改keepalived.conf配置文件：
[root@haproxy2 keepalived]# vim /etc/keepalived/keepalived.conf ! Configuration File for keepalived global_defs { notification_email { root@localhost } notification_email_from root@localhost smtp_server 127.0.0.1 smtp_connect_timeout 30 router_id LVS_DEVEL } vrrp_instance VI_1 { state BACKUP interface eth1 virtual_router_id 51 priority 99 advert_int 1 authentication { auth_type PASS auth_pass a23c7f32dfb519d6a5dc67a4b2ff8f5e } virtual_ipaddress { 192.168.80.200 } } vrrp_instance VI_2 { state MASTER interface eth1 virtual_router_id 52 priority 100 advert_int 1 authentication { auth_type PASS auth_pass 56f7663077966379d4106e8ee30eb1a5 } virtual_ipaddress { 192.168.80.201 } }
重启keepalived：
1 2
[root@haproxy1 keepalived]# service keepalived restart [root@haproxy1 keepalived]# ssh haproxy2 'service keepalived restart'
配置haproxy： 先将原始配置文件进行备份：
1 2 3 4
[root@haproxy1 ~]# cd /etc/haproxy/ [root@haproxy1 haproxy]# cp haproxy.cfg{,.bak} ##节点2也进行同样的操作
编辑其配置文件修改其内容如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105
