Establishment of log collection and analysis platform-1-environment preparation

1、 Get ready 3 Build a virtual machine nginx and kafka colony

2、 Configure static ip Address

        remarks ： service ：NetworkManager perhaps network Run only one

                    start-up / stop it / restart ：systemctl start/stop/restart NetworkManager

                 systemctl Managed services Configuration file in /usr/lib/systemd/system Next , With .service Profile at the end

        Good configuration dns  Input cat /etc/resolv.conf  Check whether to enter the following

        dns Analytical process ： 

                1、 First find the browser cache

                2、 Find local hosts file  --linux（/etc/hosts）

                3、 Then find the local domain name server  -- linux（/etc/resolv.conf）

3、 Modify hostname

        vim /etc/hostname

        hostname -F /etc/hostname

4、 Domain name resolution is written on each machine

        Input vim /etc/hosts Add the following three lines to the file ( Add three lines to each set )

        ip Address 1  name 1

        ip Address 2  name 2

        ip Address 3  name 3

5、 Install basic software

        yum install wget lsof vim -y

6、 Install time synchronization service

        yum -y install chrony

        systemctl enable chronyd   # Set power on self start    disable Turn off and start automatically

        systemctl start chronyd

        Set time zone ：

        cp /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime

7、 Turn off firewall

        systemctl stop firewalld

        systemctl disable firewalld

        close selinux：

        vim /etc/selinux/config

        SELINUX=disabled

        selinux close Need to restart the machine

        Input getenforce See if it's disabled

selinux yes Linux A security related subsystem in the system kernel     The rules are very cumbersome     Generally, it is closed in daily work
