systemctl start network job for network.service failed. see 'systemctl status network.service' and 'journalctl -xn' for details journalctl -xn ## 关键信息 RTNETLINK answer: File exists network.service: control process exited, code=exited styatus=1 failed to start LSB: Bring up/down networking
排查过程:
报错信息中有关键字”file exists”
ifconfig结果中只有lo和eno16777736
nmcli con show 有两个连接eno16777736和eno33554992
# 尝试把eno33554992先备份掉 cd /etc/sysconfig/network-scripts/ mv ifcfg-eno33554992 ifcfg-eno33554992.bak systemctl start network # 再没有报错
network和NetworkManager服务启动后，nmcli con show 发现还是有两个连接，而且名称全部是”eno16777736”，一个设备名称是”eno16777736”，另一个是”–“。
处理过程：
# 删掉旧连接 nmcli con delete eno16777736 # 发现两个连接都消失掉，重建连接 nmcli con add type ethernet con-name eth0 ifname eno16777736 nmcli con reload nmcli con down eth0 nmcli con up eth0 ping 8.8.8.8 # 成功解决
