配置环境

准备： 三台虚拟机

配置主节点：

1. 查看当前使用网卡

[[email protected] ~]# dmesg | grep -i eth
Bluetooth: BNEP (Ethernet Emulation) ver 1.3
eth0: no IPv6 routers present

dmesg是显示开机启动信息， grep -i是忽略大小写查找

2. 查看当前ip、网关

[[email protected] ~]# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0C:29:E0:C3:61
          inet addr:192.168.182.138  Bcast:192.168.182.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fee0:c361/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:12373 errors:0 dropped:0 overruns:0 carrier:0

          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:8 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:480 (480.0 b)  TX bytes:480 (480.0 b)

配置静态IP：

[[email protected] ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
#BOOTPROTO="dhcp"
BOOTPROTO="static"
HWADDR="00:0C:29:E0:C3:61"
#IPV6INIT="yes"
IPV6INIT="no"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="7039ffae-3334-4445-b571-a805eecd4a77"
IPADDR=192.168.182.101
NETMASK=255.255.255.0
GATEWAY=192.168.182.255

修改主机名：

[[email protected] ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=master
[[email protected] ~]# hostname master
[[email protected] ~]# hostname
master

修改hosts文件：

[[email protected] ~]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.182.101 master

关闭防火墙（生产环境不能关闭， 需要添加允许列表）

[[email protected] ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[[email protected] ~]# chkconfig iptables off

关闭
selinux

[[email protected] ~]# vi /etc/selinux/config

将SELINUX的值对应修改为： SELINUX=disabled

将两台从属节点按照上面的配置配好， ip分别设置为192.168.182.102和192.168.182.103， 主机名分别为slave1、slave2。
