1、WORD格式整理本机windows的ip192.168.3.2台式机的ip192.168.3.9笔记本的linuxmasterip3.3台机机两个linuxslave1slave2ip3.1003.101专业知识分享WORD格式整理上传工具保证FTP开启[root@localhost~]#/etc/init.d/vsftpdrestart关闭vsftpd：[失败]为vsftpd启动vsftpd：[确定][root@localhost~]#[root@localhostvsftpd]#lsftpusersuser_listvs

2、ftpd.confvsftpd_conf_migrate.sh[root@localhostvsftpd]#ftpusersuser_list这两个文件中的root用户注释掉然后重启[root@localhostvsftpd]#/etc/init.d/vsftpdrestart配置主机名[root@localhost~]#vim/etc/sysconfig/networkNETWORKING=yesNETWORKING_IPV6=noHOSTNAME=master[root@localhost~]#hostnamemaste

3、r三台主机都配置主机名[root@localhost~]#vim/etc/sysconfig/networkNETWORKING=yesNETWORKING_IPV6=noHOSTNAME=slave1[root@localhost~]#hostnameslave1[root@localhost~]#vim/etc/sysconfig/networkNETWORKING=yesNETWORKING_IPV6=noHOSTNAME=slave2[root@localhost~]#hostnameslave2专业知识分享WORD
