How to creat galera resources in Pacemaker

[Hân Diệp]

Hi everybody,

I'm having a problem when my HA database, topology

Here is the configuration in the galera cluster:

[galera]

binlog_format = ROW

default-storage-engine = innodb

innodb_autoinc_lock_mode = 2

bind-address = 0.0.0.0

wsrep_on = ON

wsrep_provider = / usr / lib64 / galera / libgalera_smm.so

wsrep_cluster_address = "gcomm: //10.120.190.61,10.120.190.62,10.120.190.63"

## Galera Cluster Configuration

wsrep_cluster_name = "galera"

## Galera Synchronization Configuration

wsrep_sst_method = rsync

## Galera Node Configuration

wsrep_node_address = "10.120.190.61"

wsrep_node_name = "DB1"

The galera cluster was able to sync well, but my problem is: when I create resource galera for pacemaker then pacemaker cannot be promoted master

Here is my pacemaker setup:

#yum -y install pacemaker pcs

#pcs property set stonith-enabled = false

#pcs property set no-quorum-policy = ignore

#pcs property set default-resource-stickiness = "INFINITY"

#pcs resource create Virtual_IP ocf: heartbeat: IPaddr2 ip = 10.123.70.60 cidr_netmask = 24 op monitor interval = 30s

#pcs resource create p_galera ocf: heartbeat: galera \

wsrep_cluster_address = gcomm: // DB1, DB2, DB3 \

op monitor depth = "0" timeout = "30s" interval = "20s" \

op monitor role = "Master" depth = "0" timeout = "30s" interval = "10s" \

op monitor role = "Slave" depth = "0" timeout = "30s" interval = "30s" --master

Error:

"resource is master / slave but has not been promoted to master on any node"

I didn't disable the mariadb service when adding galera to pacemaker, but I tried disabling mariadb and still failed

Please help me, I am using centos 7.8 and mariadb 10.3.27, pacemaker 0.10.6

Thanks very much!
