我试图在MariaDB的24年1月10日设置HA服务器，CentOS7MariaDB的HA安装上MariaDB10.1.24，CentOS7
我设置好的复制西弗斯（master1，SLAVE1，SLAVE2）和安装mha4mysql节点-0.56.tar.gz和思想的作品好，但是当我指挥 “masterha_check_repl --conf =的/ etc/app1.cnf” 来管理服务器它显示错误
[[email protected] ~]# masterha_check_repl --conf=/etc/app1.cnf

这里的app1.cnf配置（管理服务器）
[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
我有没有安装MHA的版本不对？或者我错过了什么？ 任何人都可以为我提供建议吗？
