需求：本实验为单节点nginx为两台apache服务器提供负载均衡，所有配置为最简单
1.初始化3台测试server，该关的关了
[root@host101 ~]# vim /etc/hosts 192.168.1.101 ng-master 192.168.1.161 web1 192.168.1.162 web2 [root@host101 ~]# yum clean all [root@host101 ~]# systemctl stop firewalld.service [root@host101 ~]# systemctl disable firewalld.service [root@host101 ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
2.配置web1,web2的apache服务
[root@host161 ~]# yum -y install httpd [root@host161 ~]# systemctl start httpd [root@host161 ~]# systemctl enable httpd ln -s ‘/usr/lib/systemd/system/httpd.service‘ ‘/etc/systemd/system/multiuser.target.wants/httpd.service‘ [root@host161 ~]# cat /var/www/html/index.html hello this lvs-web1
3.通过yum安装配置nginx节点
[root@host101 ~]# vim /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/x86_64/
gpgcheck=0
enabled=1
[root@host101 ~]# yum clean all
[root@host101 ~]# yum -y install nginx
[root@host101 ~]# vim /usr/share/nginx/html/index.html
<h1>Welcome to ng-master!</h1>
[root@host101 ~]# cd /etc/nginx/conf.d/
[root@host101 conf.d]# mv default.conf default.conf.1
[root@host101 ~]# vim /etc/nginx/conf.d/web.conf
upstream myapp1 {
server web1;
server web2;
}
server {
listen 80;
location / {
proxy_pass http://myapp1;
}
}
[root@host101 ~]# systemctl restart nginx.service
4.查看nginx相关日志
[root@host101 conf.d]# tail -f /var/log/messages [root@host101 conf.d]# tail -f /var/log/nginx/access.log [root@host101 conf.d]# tail -f /var/log/nginx/error.log
5.通过浏览器访问测试http://192.168.1.101/ 或者 http://myapp1/ 可发现流量在web1和web2之间跳转
