CentOS 安装 apache

前端之家收集整理的这篇文章主要介绍了CentOS 安装 apache前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

apache在centos7中是Apache HTTP server。如下对httpd的解释就是Apache HTTP Server。所以想安装apache其实是要安装httpd。


[root@localhost ~]# yum install httpd #安装


[root@localhost ~]# chkconfig httpd on#设置开机启动

Note: Forwarding request to 'systemctl enable httpd.service'.

Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.

[root@localhost ~]#



[root@localhost ~]# service httpd start#启动服务

Redirecting to /bin/systemctl start httpd.service

[root@localhost ~]#



[root@localhost ~]# netstat -ntlp#查看 80 端口是否启动

Active Internet connections (only servers)

tcp6 0 0 :::22 :::* LISTEN 958/sshd

tcp6 0 0 ::1:25 :::* LISTEN 1456/master

[root@localhost ~]#


到这里时,在本机是可以访问 web 的,但其他局域网电脑不可以访问 web,此原因是防火墙导致:

[root@localhost ~]# curl 127.0.0.1


开启防火墙:centos的防火墙改成了firewall,不再叫iptables,开放端口的方法如下

[root@localhost ~]# firewall-cmd --zone=public --add-port=80/tcp --permanent

success

[root@localhost ~]#


命令含义:

--zone #作用域

--add-port=80/tcp #添加端口,格式为:端口/通讯协议

--permanent #永久生效,没有此参数重启后失效


重启防火墙命令:

[root@localhost ~]# systemctl restart firewalld.service

[root@localhost ~]# systemctl stop firewalld.service

[root@localhost ~]# systemctl start firewalld.service


到这里,局域网电脑就可以访问 web了
