4. Installation command: yum install -y package name
5. List the rpm package of the group: yum grouplist
6. If you want to install the rpm package of the group, you can use the command to install: yum groupinstall -y package name
7. Uninstall command: yum remove -y package name

yum builds local warehouse
What should I do if yum cannot be used because of the inability to connect to the Internet? Let's build a local yum source installation.
(The premise is to have a CD-ROM, a CD-ROM, an image file, and then mount the CD-ROM)
1. Mount the image to the /mnt directory (because it has been mounted before, so this step is directly passed)
2. Use the command to back up the yum.repos.d file: cp -r /etc/yum.repos.d/ /etc/yum.bak.repo
3. Then delete all repo suffix files in the /etc directory: rm -f /etc/yum.repos.d/*
4. Use the command to edit: vim /etc/yum.repos.d/base.repo
[base]
name=base
baseurl=file:///misc/cd
enable=1
gpgcheck=0
5. Use the command yum clean all to clear the cache
6. Use the command yum list to view and install
centos6 compile and install httpd2.2
Preparation:
1 Close firwalld
centos6: service iptables stop;
chkconfig iptables off
centos7: systemctl stop firewalld;
systemctl disable firewalld
2 关闭SElinux
setenforce 0
vim /etc/selinux/config
SELINUX=disabled
1. yum groupinstall "development tools" (install package group files)
yum install openssl-devel (install missing packages)
2 、download src
tar xvf httpd-2.4.33.tar.bz2（解包)
3 、cd httpd-2.2.34
cat README
cat INSTALL
4 、./configure --help（编译安装查看帮助）
./configure --prefix=/app --sysconfdir=/etc/httpd22 --enable-ssl
5、 make -j 4 && make install
6 、vim /etc/profile.d/env.sh
PATH=/app/bin:$PATH
. /etc/profile.d/env.sh（更改后的变量source一下）
7、apachectl start （运行服务）
