[root@xingdiancloud-native-master-a ~]# ssh-copy-id root@xingdiancloud-native-master-a
[root@xingdiancloud-native-master-a ~]# ssh-copy-id root@xingdiancloud-native-node-b
[root@xingdiancloud-native-master-a ~]# ssh-copy-id root@xingdiancloud-native-node-a
[root@xingdiancloud-native-master-a ~]# ssh-copy-id root@xingdiancloud-native-node-c
```

## 三：部署负载均衡高可用

#### 1.安装haproxy与keepalived

在HA部署的节点上运行，本次HA部署在xingdiancloud-master-a,xingdiancloud-master-b上

```
[root@xingdiancloud-native-master-a ~]# yum -y install haproxy keepalived
```

#### 2.HAProxy配置

在HA部署的节点上运行， HAProxy配置所有节点相同

```shell
[root@xingdiancloud-native-master-a ~]# cat >/etc/haproxy/haproxy.cfg<<"EOF"
global
 maxconn 2000
 ulimit-n 16384

 server  xingdiancloud-master-b  10.9.12.64:6442 check
EOF
```

#### 3.KeepAlived配置

主从配置不一致，需要注意	

Master：

```shell
[root@xingdiancloud-native-master-a ~]# cat >/etc/keepalived/keepalived.conf<<"EOF"
! Configuration File for keepalived
global_defs {
   router_id LVS_DEVEL
script_user root
   enable_script_security
}
vrrp_script chk_apiserver {
   script "/etc/keepalived/check_apiserver.sh"
   interval 5
   weight -5
   fall 2 
rise 1
}
vrrp_instance VI_1 {
   state MASTER
   interface ens3
   mcast_src_ip 10.9.12.60
   virtual_router_id 51
   priority 100
   advert_int 2
   authentication {
       auth_type PASS
       auth_pass K8SHA_KA_AUTH
   }
   virtual_ipaddress {
       10.9.12.100
   }
   track_script {
      chk_apiserver
   }
}
EOF
```

Backup：

```shell
[root@xingdiancloud-native-master-b ~]# cat >/etc/keepalived/keepalived.conf<<"EOF"
! Configuration File for keepalived
global_defs {
   router_id LVS_DEVEL
script_user root
   enable_script_security
}
vrrp_script chk_apiserver {
   script "/etc/keepalived/check_apiserver.sh"
  interval 5
   weight -5
   fall 2 
rise 1
}
vrrp_instance VI_1 {
   state BACKUP
   interface ens3
   mcast_src_ip 10.9.12.64
   virtual_router_id 51
   priority 99
   advert_int 2
   authentication {
       auth_type PASS
       auth_pass K8SHA_KA_AUTH
   }
   virtual_ipaddress {
       10.9.12.100
   }
   track_script {
      chk_apiserver
   }
}
EOF
```

#### 4.健康检测脚本

Master和Backup节点均要有

```shell
[root@xingdiancloud-native-master-a ~]# cat > /etc/keepalived/check_apiserver.sh <<"EOF"
#!/bin/bash
err=0
for k in $(seq 1 2)
do
   check_code=$(pgrep haproxy)
   if [[ $check_code == "" ]]; then
       err=$(expr $err + 1)
       sleep 1
       continue
   else
       err=0
       break
   fi
done

if [[ $err != "0" ]]; then
   echo "systemctl stop keepalived"
   /usr/bin/systemctl stop keepalived
   exit 1
else
   exit 0
fi
EOF

[root@xingdiancloud-native-master-a ~]# chmod +x /etc/keepalived/check_apiserver.sh
```

#### 5.启动服务并验证

```shell
[root@xingdiancloud-native-master-a ~]# systemctl daemon-reload
[root@xingdiancloud-native-master-a ~]# systemctl enable --now haproxy
[root@xingdiancloud-native-master-a ~]# systemctl enable --now keepalived
```

注意：

	依次启动Master节点和Backup节点

验证VIP：

```shell
[root@xingdiancloud-native-master-a ~]# ip a s
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
