Description

Here we use VMware to create three master node machines and one node node. The process of creating a virtual machine is not described because it is not the focus of this section. The details of the three machines are as follows:

Master node 1: 192.168.246.193 hostname: master01master node 2: 192.168.246.194 hostname: master02master node 3: 192.168.246.195 hostname: master03Node node 1: 192.168.246.196 hostname: node01 fixed virtual machine IP and can access the network normally

The four machines are all operated as follows:

The IP of the host is 192.168.246.193max 194max 195ax.

# Virtual machine network select network adapter-> NAT# change virtual machine network configuration file cd / etc/sysconfig/network-scriptscat > ifcfg-ens33 > / etc/resolv.conf# restart network card systemctl restart network change host name

The four machines are all operated as follows:

The host names are: master01, master02, master03, node01

Hostnamectl set-hostname master01hostname master01bash uses Ali Cloud yum source

The four machines are all operated as follows:

# delete yum source cache data rm-rf / var/cache/yum/x86_64/7/*# Delete the default source rm-rf / etc/yum.repos.d/*# in the system add aliyun base source wget-O / etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo# add aliyun EPEL source wget-P / etc/yum.repos.d/ http://mirrors.aliyun.com/repo / epel-7.repo # Clean the cache and generate a new cache yum clean allyum makecache# to view the currently used yum source yum repolist installation dependent packages

The four machines are all operated as follows:

Yum install-y conntrack ntpdate ntp ipvsadm ipset jq iptables curl sysstat libseccomp wget vim net-tools git sets the firewall to Iptables and sets an empty rule

The four machines are all operated as follows:

Systemctl stop firewalld & & systemctl disable firewalldyum-y install iptables-services & & systemctl start iptables & & systemctl enable iptables & & iptables- F & & service iptables save & & iptables- nvL close SELINUX

The four machines are all operated as follows:

The four machines are all operated as follows:
