1. Basic environment system version nginx version keepalived version ip function CentOS Linux release 7.6nginx/1.18.0keepalived-2.1.5192.168.86.135masterCentOS Linux release 7.6nginx/1.18.0keepalived-2.1.5192.168.86.136slave

VIP:192.168.86.137

II. Installation of the compiler environment

Yum-y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel pcre pcre-devel

III. Install nginx

Install nignx

# enter the directory cd / tools # to upload installation files And extract tar-zxvf nginx-1.18.0.tar.gz# into the installation directory cd nginx-1.18.0# to check the configuration. / configure-- prefix=/usr/local/nginx make&&make install# to view the nginx version / usr/local/nginx/sbin/nginx-v# configuration nginx (check) / usr/local/nginx/sbin/nginx-t#nginx management commands / usr/local/nginx/sbin/nginx # start / usr/local/nginx/sbin/nginx-s stop # stop / usr/local/nginx/sbin/nginx-s reload # reload the configuration file

Modify nginx configuration file

Modify the content of the Nginx welcome home page (for later testing, to distinguish the Nginx of the two nodes):

Master

Echo 'this is master 135' > / usr/share/nginx/html/index.html

Slave

Echo 'this is slave 136' > / usr/share/nginx/html/index.html

Modify nginx.conf

# vi / usr/local/nginx/conf/nginx.conuser root;worker_processes 1 leading errorists log logs/error.log;#error_log logs/error.log notice;#error_log logs/error.log info;#pid logs/nginx.pid;events {worker_connections 1024;} http {include mime.types; default_type application/octet-stream # log_format main'$remote_addr-$remote_user [$time_local] "$request" #'$status $body_bytes_sent "$http_referer" #'"$http_user_agent"$http_x_forwarded_for"; # access_log logs/access.log main; sendfile on; # tcp_nopush on; # keepalive_timeout 0; keepalive_timeout 65 # gzip on; server {listen 88; server_name localhost; # charset koi8-r; # access_log logs/host.access.log main; location / {root html; index index.html index.htm } # error_page 404 / 404.html; # redirect server error pages to the static page / 50x.html error_page 500502 503504 / 50x.html; location = / 50x.html {root html;}

Start nginx

Systemctl start nginx

Test nginx startup
