我試圖在MariaDB的24年1月10日設置HA服務器，CentOS7MariaDB的HA安裝上MariaDB10.1.24，CentOS7
我設置好的複製西弗斯（master1，SLAVE1，SLAVE2）和安裝mha4mysql節點-0.56.tar.gz和思想的作品好，但是當我指揮 「masterha_check_repl --conf =的/ etc/app1.cnf」 來管理服務器它顯示錯誤
[[email protected] ~]# masterha_check_repl --conf=/etc/app1.cnf

在/ usr/local/share下/ perl5/MHA/MasterMonitor.pm 236行

my $command =

$command .= $current_master->get_ssh_args_if(1, "orig", 1);
$log->info("Checking master_ip_failover_script status:");
$log->info(" $command");
my ($high, $low) = MHA::ManagerUtil::exec_system($command, $g_logfile);
if ($high == 0 && $low == 0) {
$log->info(" OK.");
}
else {
$log->error(

}

}
if ($current_master->{shutdown_script}) {
my $command =
"$current_master->{shutdown_script} --command=status --ssh_user=$current_master->{ssh_user} --host=$current_master->{hostname} --ip=$current_master->{ip}";
$command .= $current_master->get_ssh_args_if(1, "shutdown", 1);
$log->info("Checking shutdown script status:"); //line 236
$log->info(" $command");
my ($high, $low) = MHA::ManagerUtil::exec_system($command, $g_logfile);
if ($high == 0 && $low == 0) {
$log->info(" OK.");
}
else {
$log->error(" Failed to get power status with return code $high:$low.");
croak;
}
}
else {
$log->warning("shutdown_script is not defined.");
}
}
這裏的app1.cnf配置（管理服務器）
[server default]
# mysql user and password
user=mhauser
password=1234
ssh_user=root
# working directory on the manager
manager_workdir=/home/mhauser/mysql
# manager log file
manager_log=/home/mhauser/mysql/mha.log
# working directory on MySQL servers
remote_workdir=/home/mhauser/mysql
[server1]
hostname=192.168.0.3
master_binlog_dir=/usr/local/mariadb/data
candidate_master=1
[server2]
hostname=192.168.0.4
master_binlog_dir=/usr/local/mariadb/data
candidate_master=1
[server3]
hostname=192.168.0.5
master_binlog_dir=/usr/local/mariadb/data
no_master=1
我有沒有安裝MHA的版本不對？或者我錯過了什麼？ 任何人都可以爲我提供建議嗎？
