主机部署：

import configparser import os def config_mariadb_yum(): exists = os.path.exists(‘/etc/yum.repos.d/mariadb.repo‘) if exists: print(‘mariadb.repo文件已经存在‘) yum_install_mariadb() else: config = configparser.ConfigParser() config.read(‘/etc/yum.repos.d/mariadb.repo‘, encoding=‘utf-8‘) config.add_section(‘mariadb‘) config.set(‘mariadb‘, ‘name‘, ‘MariaDB‘) config.set(‘mariadb‘, ‘baseurl‘, ‘http://mirrors.ustc.edu.cn/mariadb/yum/10.3/centos7-amd64/‘) config.set(‘mariadb‘, ‘gpgkey‘, ‘http://mirrors.ustc.edu.cn/mariadb/yum/RPM-GPG-KEY-MariaDB‘) config.set(‘mariadb‘, ‘gpgcheck‘, ‘1‘) config.write(open("/etc/yum.repos.d/mariadb.repo", "w")) yum_install_mariadb() def yum_install_mariadb(): res1 = os.system(‘yum install MariaDB -y > /dev/null 2&>1‘) if res1 == 0: config = configparser.ConfigParser() config.read(‘/etc/my.cnf.d/server.cnf‘, encoding=‘utf-8‘) config.set(‘server‘,‘server_id‘,‘1‘) config.set(‘server‘,‘log-bin‘,‘mysql-bin‘) config.write(open("/etc/my.cnf.d/server.cnf", "w")) res2 = os.system(‘service mariadb restart‘) if res2 == 0: os.system(‘mysql_secure_installation‘) os.system(‘‘‘mysql -uroot -proot -e "grant replication slave on *.* to ‘slave‘@‘%‘ identified by ‘slave‘"‘‘‘) os.system("mysql -uroot -proot -e ‘show master status‘") def main(): config_mariadb_yum() if __name__ == ‘__main__‘: main()
