CENTOS7离线安装CDH5.6遇到的问题

1，安装cloudera-manager-agent 时，报错，报端口80问题，

开启80端口

firewall-cmd --zone=public --add-port=80/tcp --permanent

出现success表明添加成功

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

运行、停止、禁用firewalld

启动：# systemctl start  firewalld

查看状态：# systemctl status firewalld 或者 firewall-cmd --state

停止：# systemctl disable firewalld

禁用：# systemctl stop firewalld

systemctl disable firewalld.service #禁止firewall开机启动

端口开启后正常，centos 7的防火墙已不是iptables了（对系统不熟悉）。

2，修改主机名

Centos 7.1下修改主机名：

[root@localhost ~]# hostnamectl status
   Static hostname: localhost.localdomain
         Icon name: computer
           Chassis: n/a
        Machine ID: caa35e54020e4930a35b28c8e501b51a
           Boot ID: 95321dfa104f423d9d1fc7dbade66dbb
    Virtualization: vmware
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-229.el7.x86_64
      Architecture: x86_64
[root@localhost ~]# hostnamectl set-hostname  master
[root@localhost ~]# hostnamectl status
   Static hostname: master
         Icon name: computer
           Chassis: n/a
        Machine ID: caa35e54020e4930a35b28c8e501b51a
           Boot ID: 95321dfa104f423d9d1fc7dbade66dbb

       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 3.10.0-229.el7.x86_64
      Architecture: x86_64

3, 安装提示失败，无法安装包

为CM创建索引
