我不想在CentOS/RHEL 6服务器上使用Apache服务器。
如何在基于Red Hat Enterprise Linux/CentOS/Fedora Linux的服务器上使用命令行选项卸载和删除Apache(HTTPD)服务器？

您需要在CentOS/RHEL上卸载以下软件包：

• httpd
• httpd工具
• 4月
• 实用程序

警告：备份存储在DocumentRoot中的Apache数据(默认为/var/www /)，/etc/httpd /中的配置文件以及数据库(如果有)。

在CentOS/Red Hat Enterprise Linux(RHEL)上卸载Apache

以root用户身份登录，然后执行以下yum命令：

$ sudo yum erase httpd httpd-tools apr apr-util

或者

# yum erase httpd httpd-tools apr apr-util

输出示例：

更新您的防火墙配置

您需要编辑/etc/sysconfig/iptables并删除允许Apache使用TCP端口80/443的行：

# vi /etc/sysconfig/iptables

查找并删除行，如下所示：

## open port 80 /443 ##
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

保存并关闭文件。
重启iptables：

# service iptables restart

您需要通过编辑/etc/sysconfig/ip6tables对ip6tables IPv6数据包过滤器重复相同的步骤。

# vi /etc/sysconfig/ip6tables

查找并删除行，如下所示：

## open port 80 /443 for IPv6 ##
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

保存并关闭文件。
重新启动ip6tables服务：

# service ip6tables restart
