前言
秋招拿到了科大讯飞的offer，可是由于某些原因无法完成三方签署，心情还是比较失落的，或许写一篇技术博客，活跃一下大脑思维也是一种不错的放松方式。
一.网络服务
开启network服务
此脚本用于关闭NetworkManger服务重启network防止服务冲突导致IP配置无法生效
#!/bin/bash# 获取 NetworkManager 的 Active 状态（去除括号）
status=$(systemctl status NetworkManager | grep 'Active:' | awk '{print $3}' | tr -d '()')# 检查状态是否不是 dead
if [ "$status" != "dead" ]; thenecho "NetworkManager is not dead. Stopping NetworkManager and restarting network..."# 停止 NetworkManagersystemctl stop NetworkManager# 检查 systemctl stop 的退出状态if [ $? -ne 0 ]; thenecho "Failed to stop NetworkManager."exit 1fi# 重启 network 服务（注意：这个服务名可能因系统而异，例如在某些系统上可能是 'networking'）systemctl restart network# 检查 systemctl restart 的退出状态if [ $? -ne 0 ]; thenecho "Failed to restart network service."exit 1fiecho "NetworkManager stopped and network service restarted successfully."
elseecho "NetworkManager网口IP配置
此脚本用于配置网口IP地址，简化命令行操作
#!/bin/bash
interfaces=$(ip a | awk '/^[0-9]: / {printf "%s ", $2} END {print ""}')
echo "可选择网卡如下：$interfaces"
read -p "请输入网口：" eth
read -p "请输入IP：" eth_ip
read -p "请输入mask:" eth_mask
echo "IPADDR=$eth_ip" >> /etc/sysconfig/network-scripts/ifcfg-$eth
echo "NETMASK=$eth_mask" >> /etc/sysconfig/network-scripts/ifcfg-$eth
echo "正在重启网络"
systemctl restart network
echo "重启成功"聚合口配置
此脚本用于自动配置聚合口
#!/bin/bash
status=$(systemctl status NetworkManager | grep 'Active:' | awk '{print $3}' | tr -d '()')
if [ "$status" != "dead" ]
thenecho "NetworkManager服务已开启"
else# 开启 NetworkManagerecho "正在重启NetworkManager"systemctl restart NetworkManagerecho "重启成功"
