centos系统systemctl restart network启动失败，提示“code=exited status=1”

centos虚拟机时我复制过来的，IP地址、mac地址都与别人的冲突，首先需要修改mac地址和ip地址。

修改ip配置 /etc/sysconfig/network-scripts/ifcfg-ens33，注意修改一下4个红色字体的参数

[root@localhost bin]# more /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
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=a903e483-d2b3-407d-8327-3cd37d4785f2
DEVICE=ens33
ONBOOT=yes

IPADDR=192.168.226.129
NETMASK=255.255.255.0
GATEWAY=
DNS=192.168.226.2

HWADDR=00:50:56:3C:91:A4

然后执行systemctl restart network启动失败

解决办法：

systemctl stop NetworkManager
systemctl disable NetworkManager
reboot

systemctl start network.service
