linux查找、解压打包、sed、RPM、yum、源码

find -not -user root -a -not -user lp -a -not -user gdm

2、统计/etc/init.d/functions文件中每个单词的出现次数并排序（用grep和sed）

grep -o "\<[[:alpha:]]+\>" /etc/init.d/functions | sort | uniq -c |wc -l

grep -o "\<[[:alpha:]]+\>" /etc/init.d/functions | sort -u |wc -l

sed -nr ‘/\<[[:alpha:]]+\>/p‘ /etc/init.d/functions | sort -u |wc -l

但是sed和grep的统计次数不一样，不是很明白，请解惑.......
3 、利用sed取出ifconfig命令中本机的IPv4地址

ifconfig ens33 | sed -n ‘2p‘ | sed ‘s/.inet//‘ | sed s‘/ netmask.$//‘

ifconfig ens33 | sed -nr ‘2s/.t (.) net.*$/\1/p‘

ifconfig ens33 | sed -nr ‘2s/(^.inet )(.)( netmask.*$)/\2/p‘

ifconfig ens33 | sed -nr ‘2s/^.inet (.) net.*$/\1/p‘

4、总结yum的配置和使用，包括yum仓库的创建

yum install tree -y

yum repolist

yum clean all

yum reinstall tree

yum remove tree

yum本地仓库创建网络源
cd yum.repos.d
vim base.repo
[epel]
name=epel
baseurl=https://mirros.tuna.tsinghua.edu.cn/epel/$releasever/$basearch
gpgcheck=0

5、编写初始化脚本reset.sh 包括别名，提示符颜色，yum仓库配置文件

6、安装tree、ftp、lftp、telnet

yum -y install tree yum -y install ftp yum -y install lftp yum -y install telnet

7、在centos7上编译安装apache2.4源码包，并启动此服务

rz好像不行。。。

步骤：

1 tar xf httpd-2.4.25.tar.bz2

2 cd httpd-2.4.25/

3 yum groupinstall "development tools"

4 cat readme、cat install

5 ./configure --prefix /app/httpd --enable-ssl

6 yum install -y apr-devel 、yum install -y apr-util-devel 、yum install -y pcre-devel yum install -y openssl-devel

7 ./configure --prefix /app/httpd --enable-ssl

8 make

9 make install

10 echo ‘PATH=/app/httpd/bin:$PATH‘ > /etc/profile.d/httpd.sh

11 ./etc/profile.d/httpd.sh

12 apachectl start

或者

10 cd /app/httpd/bin

11 ./apachectl start
