企业自建私有云-openstack-负载keepalive+haproxy(容灾节点)

发布时间：2023-11-05 15:30

安装keepalived容灾节点

  1. 安装

    yum install -y keepalived

  2. 修改keepalived配置文件容灾节点

    vi /etc/keepalived/keepalived.conf
! Configuration File for keepalived

global_defs {
   router_id LVS_OPENSTACK
   vrrp_iptables
}
vrrp_instance VI_1 {
    state MASTER(BACKUP)
    interface ens192
    virtual_router_id 192
    priority 100(备50)
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 192
    }
    virtual_ipaddress {
        192.168.188.20/24
    }
}

  3. 启动keepalived容灾节点

    systemctl restart keepalived

    启动时会自动添加一个drop的防火墙规则，需要清空

    iptables -F
systemctl status keepalived
systemctl enable keepalived

  4. 查看vip

    ip add | grep 188.20

安装haproxy容灾节点

  1. 安装

    yum install -y haproxy

  2. 创建HAProxy记录日志文件并授权容灾节点

    mkdir /var/log/haproxy
touch /var/log/haproxy/haproxy-info.log
touch /var/log/haproxy/haproxy-err.log
touch /var/log/haproxy/haproxy-notice.log
chmod -R 777 /var/log/haproxy

    在rsyslog文件下修改以下字段

    vi /etc/rsyslog.conf
module(load=\"imudp\")
input(type=\"imudp\" port=\"514\")
module(load=\"imtcp\")
input(type=\"imtcp\" port=\"514\")
#### GLOBAL DIRECTIVES ####
		#在文件最后添加haproxy配置日志
local0.=info    -/var/log/haproxy/haproxy-info.log
local0.=err     -/var/log/haproxy/haproxy-err.log
local0.notice;local0.!=err      -/var/log/haproxy/haproxy-notice.log

    重启rsyslog

    systemctl restart rsyslog

  3. 上传并修改配置文件容灾节点

    vi /etc/haproxy/haproxy.cfg
