[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 |

[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
