opengauss 5.0.0 添加VIP配置

一、配置omm用户ifconfig权限

echo >>  /etc/sudoers  << EOF
omm  ALL=(ALL) NOPASSWD:ALL
EOF
复制

二、配置cluster_config.xml

<PARAM name="floatIp1" value="192.168.0.200"/>

<PARAM name="dataListenIp1" value="192.168.0.64,192.168.0.176,192.168.0.141"/>
<PARAM name="floatIpMap1" value="floatIp1,floatIp1,floatIp1"/>
复制

三、资源格式文件cm_resource.json

 cat  cm_resource.json 
{
	"resources":	[{
			"name":	"floatIp1",
			"resources_type":	"VIP",
			"instances":	[{
					"node_id":	1,
					"res_instance_id":	6001,
					"inst_attr":	"base_ip=172.28.175.198"
				}, {
					"node_id":	2,
					"res_instance_id":	6002,
					"inst_attr":	"base_ip=172.28.175.199"
				}, {
					"node_id":	3,
					"res_instance_id":	6003,
					"inst_attr":	"base_ip=172.28.175.200"
				}],
			"float_ip":	"172.28.175.242"
		}]
}
复制

四、重启集群

cm_ctl stop

cm_ctl start

五、 切换测试

cm_ctl switchover -n 2 -D /data/software/openGauss/install/data/dn
