lvs + keepalived 负载均衡方法

1.安装keepalivedyum install keepalived -y


2.安装lvs管理软件yum install ipvsadm -y

3.配置/etc/keepalived/keepalived.conf[root@keep1-122-38 ~]# cat /etc/keepalived/keepalived.conf! Configuration File for keepalivedglobal_defs { notification_email { acassen@firewall.loc failover@firewall.loc sysadmin@firewall.loc } notification_email_from Alexandre.Cassen@firewall.loc smtp_server 192.168.200.1 smtp_connect_timeout 30 router_id LVS_DEVEL vrrp_skip_check_adv_addr vrrp_strict vrrp_garp_interval 0 vrrp_gna_interval 0}vrrp_instance VI_1 { state MASTER interface eth0 virtual_router_id 51 priority 100 advert_int 1 authentication { auth_type PASS auth_pass 1111 } virtual_ipaddress { 192.168.100.200 }}virtual_server 192.168.100.200 80 { delay_loop 6 lb_algo rr lb_kind NAT persistence_timeout 50 protocol TCP real_server 192.168.100.12 8080 { weight 1 SSL_GET { url { path / digest ff20ad2481f97b1754ef3e12ecd3a9cc } url { path /mrtg/ digest 9b3a0c85a887a256d6939da88aabd8cd } connect_timeout 3 nb_get_retry 3 delay_before_retry 3 } } real_server 192.168.100.13 8080 { weight 1 SSL_GET { url { path / digest ff20ad2481f97b1754ef3e12ecd3a9cc } url { path /mrtg/ digest 9b3a0c85a887a256d6939da88aabd8cd } connect_timeout 3 nb_get_retry 3 delay_before_retry 3 }}

4.后面有两个真实的real server并且都能够访问

5.启动keepalived服务，lvs不需要systemctl start keepalived

6.查看lvs状态ipvsadm -L -n

7.这里配置lvs的算法和模式
