1.CentOS 7 Minimal 安装后配置网络
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33# 修改ONBOOT=yes[root@localhost network-scripts]# vi ifcfg-ens33
[root@localhost network-scripts]# service network restart2. 配置Xshell使用SSH远程连接虚拟机
# 查找ifconfig
[root@localhost ~]# yum search ifconfig
Loaded plugins: fastestmirror

================================ Matched: ifconfig ================================
net-tools.x86_64 : Basic networking tools# yum安装该包
[root@localhost ~]# yum -y install net-tools.x86_64# 查找宿主机的IP地址
[root@localhost ~]# ifconfig

看到当前虚拟机相对于宿主机的IP为192.168.65.128，所以如下图配置Xshell连接,
CentOS 7 连接网络成功 且 使用Xshell连接成功~
没事最好关停 SELINUX,因为 会莫名其妙的连不上数据库
echo 0 > /selinux/enforce
setenforce 0
sestatus
