Haga que la fuente yum de la red local sea http
1. Descargue el paquete de instalación localmente, tome la descarga del paquete de software vim como ejemplo
yum install --downloadonly --downloaddir=/opt/download vim
2. Copie el paquete de instalación en el servidor yum preestablecido en la LAN
[root@localhost yum]# cd /opt/yum 进入到软件包所在文件夹
[root@localhost yum]# createrepo . 创建每个软件包元数据
[root@localhost yum]# createrepo update 软件仓库中含有很多的软件包，虽然只是其中的一小部分有所改动但是你却不必为每个软件包重新产生元数据，这样做明显太浪费时间了
3. Instale el servidor httpd
[root@localhost yum]# yum -y install httpd

5. Cerrar selinux:
1) Apagar e invalidar temporalmente después de reiniciar
[root@localhost yum]# getenforce //运行命令 getenforce 获取当前selinux状态（Enforcing为开启）
Enforcing
[root@localhost yum]# setenforce 0 //运行命令 setenforce 0
[root@localhost yum]# getenforce //运行命令getenforce，状态变为 Permissive
Permissive
2) Cerrar permanentemente
Ejecute el comando: vim / etc / sysconfig / selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled #找到行：SELINUX=enforcing 替换为：SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
Después de reiniciar, ejecute el comando sestatus
[root@localhost yum]# sestatus
SELinux status: `disabled`
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: permissive
Mode from config file: disabled
Policy MLS status: enabled
