Centos7安装apache

1.配置防火墙，开启80。CentOS 7.0默认使用的是firewall作为防火墙，这里改为iptables防火墙。

#停止firewall服务
[root@localhost networkidc]#systemctl stop firewalld.service
#禁止firewall开机启动
[root@localhost networkidc]#systemctl disable firewalld.service

#安装
[root@localhost networkidc]#yum install iptables-services
#编辑防火墙配置文件
[root@localhost networkidc]#vi /etc/sysconfig/iptables
加入红色的两行代码，请注意位置一定要对应。

# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state –state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state –state NEW -m tcp -p tcp –dport 22 -j ACCEPT
-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT
-A INPUT -j REJECT –reject-with icmp-host-prohibited
-A FORWARD -j REJECT –reject-with icmp-host-prohibited
COMMIT
:wq! #保存退出

#最后重启防火墙使配置生效
[root@localhost networkidc]#systemctl restart iptables.service
#设置防火墙开机启动
[root@localhost networkidc]#systemctl enable iptables.service
3. 关闭seinux
#修改配置文件
vi /etc/selinux/config

#SELINUX=enforcing #注释掉
#SELINUXTYPE=targeted #注释掉
SELINUX=disabled #增加
:wq! #保存退出
#使配置立即生效
setenforce 0

1.安装apache

需要服务器联网

安装：[root@localhost networkidc]#yum install -y httpd

运行：[root@localhost networkidc]#/bin/systemctl start httpd.service

执行完运行命令之后是看不到效果的，这时候再输入查看apache服务状态命令来查看服务是否已经启动：

查看状态：[root@localhost networkidc]#service httpd status

Apache开启服务：[root@localhost networkidc]#systemctl start httpd

Apache停止服务：[root@localhost networkidc]#systemctl stop httpd
