题目：
完成一个shell脚本，脚本的作用。
1. 运行脚本可以显示出本机的ip地址
2. 如果ip地址中有3这个数字，那么就打印出当前的系统时间
3. 如果ip地址中不含3这个数字，就批量建立用户magedu_00, magedu_01, … magedu_100并且所有用户同属于magedu组
4. 打印出/etc/passwd这个文件中可以登陆的用户（非/usr/sbin/nologin）
5. yum安装nginx服务，并且启动该服务
6. 一个脚本完成
1、编写脚本：
[root@rocky8 scripts]#vim 2.sh
#!/bin/bash IP=$(ifconfig eth0 |sed -nr "2s/[^0-9]+([0-9.]+).*/\1/p") echo "1.显示本机IP地址:" echo $IP if [[ $IP == "3.* || *.3" ]]; then #判断IP地址中是否有3 echo $(date) else echo "2.创建用户组:" groupadd magedu echo "用户组magedu已创建" echo "3.批量创建100个用户:" for i in {01..100}; do useradd magedu_$i -g magedu &> /dev/null echo "magedu_$i is created" done fi echo "4.显示可以登陆的用户:" cat /etc/passwd |grep bash |cut -d: -f1 echo "5.安装nginx服务:" . /etc/os-release if [ $ID = "rocky" -o $ID = "centos" ];then #判断是否是rocky系统 echo OS version is rocky or centos yum -y install nginx elif [ $ID = "ubuntu" ];then #判断是否是ubuntu系统 echo OS version is Ubuntu apt update apt -y install nginx else echo "不支持OS" exit fi echo "nginx已完成安装" echo "6.开始启动nginx服务:" systemctl start nginx echo "nginx服务已启动"
2、执行结果：
[root@rocky8 scripts]#bash 2.sh 1.显示本机IP地址: 11.0.1.10 2.创建用户组: 用户组magedu已创建 3.批量创建100个用户: magedu_001 is created magedu_002 is created magedu_003 is created magedu_004 is created magedu_005 is created magedu_006 is created magedu_007 is created magedu_008 is created magedu_009 is created magedu_010 is created magedu_011 is created magedu_012 is created magedu_013 is created magedu_014 is created magedu_015 is created magedu_016 is created magedu_017 is created magedu_018 is created magedu_019 is created magedu_020 is created magedu_021 is created magedu_022 is created magedu_023 is created magedu_024 is created magedu_025 is created magedu_026 is created magedu_027 is created magedu_028 is created magedu_029 is created magedu_030 is created magedu_031 is created magedu_032 is created magedu_033 is created magedu_034 is created magedu_035 is created magedu_036 is created magedu_037 is created magedu_038 is created magedu_039 is created magedu_040 is created magedu_041 is created magedu_042 is created magedu_043 is created magedu_044 is created magedu_045 is created magedu_046 is created magedu_047 is created magedu_048 is created magedu_049 is created magedu_050 is created magedu_051 is created magedu_052 is created magedu_053 is created magedu_054 is created magedu_055 is created magedu_056 is created magedu_057 is created magedu_058 is created magedu_059 is created magedu_060 is created magedu_061 is created magedu_062 is created magedu_063 is created magedu_064 is created magedu_065 is created magedu_066 is created magedu_067 is created magedu_068 is created magedu_069 is created magedu_070 is created magedu_071 is created magedu_072 is created magedu_073 is created magedu_074 is created magedu_075 is created magedu_076 is created magedu_077 is created magedu_078 is created magedu_079 is created magedu_080 is created magedu_081 is created magedu_082 is created magedu_083 is created magedu_084 is created magedu_085 is created magedu_086 is created magedu_087 is created magedu_088 is created magedu_089 is created magedu_090 is created magedu_091 is created magedu_092 is created magedu_093 is created magedu_094 is created magedu_095 is created magedu_096 is created magedu_097 is created magedu_098 is created magedu_099 is created magedu_100 is created 4.显示可以登陆的用户: root zhang magedu_001 magedu_002 magedu_003 magedu_004 magedu_005 magedu_006 magedu_007 magedu_008 magedu_009 magedu_010 magedu_011 magedu_012 magedu_013 magedu_014 magedu_015 magedu_016 magedu_017 magedu_018 magedu_019 magedu_020 magedu_021 magedu_022 magedu_023 magedu_024 magedu_025 magedu_026 magedu_027 magedu_028 magedu_029 magedu_030 magedu_031 magedu_032 magedu_033 magedu_034 magedu_035 magedu_036 magedu_037 magedu_038 magedu_039 magedu_040 magedu_041 magedu_042 magedu_043 magedu_044 magedu_045 magedu_046 magedu_047 magedu_048 magedu_049 magedu_050 magedu_051 magedu_052 magedu_053 magedu_054 magedu_055 magedu_056 magedu_057 magedu_058 magedu_059 magedu_060 magedu_061 magedu_062 magedu_063 magedu_064 magedu_065 magedu_066 magedu_067 magedu_068 magedu_069 magedu_070 magedu_071 magedu_072 magedu_073 magedu_074 magedu_075 magedu_076 magedu_077 magedu_078 magedu_079 magedu_080 magedu_081 magedu_082 magedu_083 magedu_084 magedu_085 magedu_086 magedu_087 magedu_088 magedu_089 magedu_090 magedu_091 magedu_092 magedu_093 magedu_094 magedu_095 magedu_096 magedu_097 magedu_098 magedu_099 magedu_100 5.安装nginx服务: OS version is rocky or centos Last metadata expiration check: 0:39:09 ago on Mon 28 Nov 2022 12:11:06 AM CST.
