Single-node Nginx provides load balancing for two Apache servers (reprint)

Single-node Nginx provides load balancing for two Apache servers

Requirements: This experiment provides load balancing for two Apache servers for single-node Nginx, all configured as the simplest

1. Initialize 3 test server, the off

123456789

[[email protected] ~] # vim/etc/hosts Code class= "Bash plain" >192.168.1.101   ng-master 192.168.1.161    WEB1 192.168.1.162   web2  [ [email protected] ~] # yum clean all [[email  protected] ~] # systemctl stop Firewalld.service [[email protected] ~] # systemctl disable Firewalld.service [[email protected] ~] # sed-i "s/selinux=enforcing/selinux=disabled/g"/etc/selinux/config

2. Configure Apache Services for WEB1,WEB2

[[email protected] ~]# yum -y install httpd[[email protected] ~]# systemctl start httpd[[email protected] ~]# systemctl enable httpdln-s ‘/usr/lib/systemd/system/httpd.service‘‘/etc/systemd/system/multiuser.target.wants/httpd.service‘[[email protected] ~]# cat /var/www/html/index.htmlhello this lvs-web1

3. Configuring Nginx nodes with Yum installation

[[email protected] ~]# vim /etc/yum.repos.d/nginx.repo[nginx]name=nginx repobaseurl=http://nginx.org/packages/centos/7/x86_64/gpgcheck=0enabled=1[[email protected] ~]# yum clean all[[email protected] ~]# yum -y install nginx[[email protected] ~]# vim /usr/share/nginx/html/index.html/h1>[[email protected] ~]# cd /etc/nginx/conf.d/[[email protected] conf.d]# mv default.conf default.conf.1[[email protected] ~]# vim /etc/nginx/conf.d/web.conf    upstream myapp1 {        server web1;        server web2;    }    server {        listen 80;        location / {            proxy_pass http://myapp1;        }    }[[email protected] ~]# systemctl restart nginx.service

4. View Nginx related logs

123	[[email protected] conf.d]# tail -f /var/log/messages[[email protected] conf.d]# tail -f /var/log/nginx/access.log[[email protected] conf.d]# tail -f /var/log/nginx/error.log

5. Access test http://192.168.1.101/via browser or http://myapp1/to discover traffic between Web1 and WEB2 jumps
