[root@slave1 cyg]# service network restart
    Restarting network (via systemctl):  Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.

前提确保：  
（1）虚拟机设置-网络适配器-配置正确。【我这里是NAT模式】

可重新设置：虚拟机设置-网络适配器，移除，重新添加（NAT模式）。

（2）`/etc/sysconfig/network-scripts/ifcfg-ens-xx`文件，配置正确。

这个`ifcfg-ens-xx`中的xx，以`ip addr`显示的为准，在此是`ifcfg-ens33`。

[root@slave1 zookeeper-3.4.5]# ip addr
    ....
    2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
        link/ether 00:0c:29:dc:e2:aa brd ff:ff:ff:ff:ff:ff
        inet 192.168.172.11/24 brd 192.168.172.255 scope global ens33
           valid_lft forever preferred_lft forever
        inet6 fe80::20c:29ff:fedc:e2aa/64 scope link 
           valid_lft forever preferred_lft forever
    ...

例如：

[root@slave1 zookeeper-3.4.5]# cat /etc/sysconfig/network-scripts/ifcfg-ens33
    TYPE="Ethernet"
    PROXY_METHOD="none"
    BROWSER_ONLY="no"
    BOOTPROTO="static"
    IPADDR=192.168.172.11
    NETMASK=255.255.255.0
    GATEWAY=192.168.172.2
    DNS1=114.114.114.114
    DEFROUTE="yes"
    IPV4_FAILURE_FATAL="no"
    IPV6INIT="yes"
    IPV6_AUTOCONF="yes"
    IPV6_DEFROUTE="yes"
    IPV6_FAILURE_FATAL="no"
    IPV6_ADDR_GEN_MODE="stable-privacy"
    NAME="ens33"
    UUID="d11d791b-4b2a-4f8d-b2a3-32b0a8d281d6"
    DEVICE="ens33"
    HWADDR="00:0c:29:dc:e2:aa"
    ONBOOT="yes"

解决：

停止网络管理

systemctl stop NetworkManager

重启网络：

systemctl start network.service

查看网络状态：

systemctl status network.service

--------------------

有时，重新配置：虚拟机设置-网络适配器，即 移除、重新添加就好了

OK~
