解決centos安裝不上apache:No match for argument: httpd

找到yum.conf

[root@d78acc291c9e var]# find / -name yum.conf
/etc/yum.conf

注釋掉exclude那行，也可只刪除httpd

[main]
gpgcheck=1
installonly_limit=3
clean_requirements_on_remove=True
best=True
#exclude=httpd nginx php mysql mairadb python-psutil python2-psutil

//重新安裝
yum install httpd -y
systemctl enable httpd
systemctl start httpd
systemctl status httpd

　　Active: active (running)

　　Status: "Started, listening on: port 80"

[root@d78acc291c9e var]# httpd -v
Server version: Apache/2.4.37 (centos)
