华为鲲鹏+uos ha + lvs安装

所有ha机器执行：

apt install libdbi-perl libdbd-mysql-perl corosync pcs pacemaker crmsh

修改pcs端口(我用的默认的2224)： vim /etc/default/pcsd

systemctl restart pcsd 
pam_tally2 --user hacluster --reset ls /etc/corosync/corosync.conf

cat /etc/ha.d/ldirectord.cf

checktimeout=3
checkinterval=5
autoreload=yes

操作系统设置好hacluster用户密码

一台执行：

pcs host auth test1:2224 test2:2224 test3:2224 -u hacluster -p abc123

pcs cluster setup db_ha_lvs test1 test2 test3 transport udp link mcastport=2225 --force

pcs cluster start --all

pcs cluster enable --all

pcs property set stonith-enabled=false

crm_verify -L

pcs resource create vip --disabled ocf:heartbeat:IPaddr nic=enp8s0f0 ip=172.16.70.123 cidr_netmask=24 broadcast=172.16.70.255 op monitor interval=5s timeout=20s

pcs resource create lvs --disabled ocf:heartbeat:ldirectord op monitor interval=10s timeout=10s

pcs resource group add dbservice vip

pcs resource group add dbservice lvs

启动
pcs resource enable lvs vip

更新vip
pcs resource update vip --disabled ocf:heartbeat:IPaddr nic=enp8s0f1 ip=172.16.80.123 cidr_netmask=24 broadcast=172.16.80.255 op monitor interval=5s timeout=20s
