Linlink~文档计算节点配置
计算节点基本配置
修改主机名为"compute"
hostnamectl set-hostname compute
配置静态ip
vi /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="eedb493c-a9a3-4c24-8239-497b618e3ac4"
DEVICE="ens33"
ONBOOT="yes"
IPADDR="192.168.10.165"
NETMASK="255.255.255.0"
生成第二张网卡信息，以ens36为例子，如果是ens34或者其它请修改下面相对应的地方
nmcli con add con-name ens36 type ethernet ifname ens36
vi /etc/sysconfig/network-scripts/ifcfg-ens36
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="d6084321-b13a-43b9-a474-26cb3ca78413"
DEVICE="ens33"
ONBOOT="yes"
IPV6_PRIVACY="no"
IPADDR="192.168.20.175"
NETMASK="255.255.255.0"
GATEWAY="192.168.20.2"
重启网卡
systemctl restart network
配置DNS服务器
echo 'nameserver 192.168.20.2' >> /etc/resolv.conf
安装时间同步服务
yum install -y chrony net-tools telnet telnet-server
修改时间同步服务文件(第三行),多的三个删掉
[root@compute1 ~]# vi /etc/chrony.conf
# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
server controller iburst
重启时间同步服务
systemctl restart chronyd.service
查看时间同步服务状态，^*表示成功，^?表示没有成功(记得重启服务器)
[root@compute1 ~]# chronyc sources
210 Number of sources = 1
MS Name/IP address Stratum Poll Reach LastRx Last sample

^* controller 3 6 17 25 -6192us[ -190ms] +/- 44ms
添加本地解析，查看本地解析情况
echo 192.168.10.160 controller >> /etc/hosts
echo 192.168.10.165 compute >> /etc/hosts
[root@compute1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.160 controller
192.168.10.165 compute
测试内网连通性
ping controller
关闭防火墙
systemctl stop firewalld.service && systemctl disable firewalld.service
关闭SeLinux(这个绝对重要)，让SELINUX=disabled
vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
重启
reboot
