环境准备
三台centos虚拟机
三台虚拟机都需要执行
#安装软件包 [root@drlvs ~]# yum install bash* net-tools vim -y [root@drlvs ~]# su root #关闭防火墙 [root@drlvs ~]# systemctl stop firewalld.service #关闭防火墙开机自启 [root@drlvs ~]# systemctl disable firewalld.service Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service. Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. #临时关闭selinux [root@drlvs ~]# setenforce 0 #永久关闭selinux 把SELINUX的值改成disabled [root@drlvs ~]# vim /etc/selinux/config [root@drlvs ~]# cat /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted
lvs虚拟机执行
