更新代码
1.web服务器准备
192.168.1.43
192.168.1.254
1.1 nginx配置文件
cat /etc/nginx/conf.d/81.conf
server {
listen 81;
server_name localhost;
access_log /var/log/nginx/test_81_access.log;
error_log /var/log/nginx/test_81_error.log;
location / {
root /html/web;
index index.html index.htm;
}
}
2. slb服务器准备
192.168.1.191
nginx七层反向代理 upstream
root@rongbiz:~# cat /etc/nginx/conf.d/slb.conf
upstream ansible_slb {
server 192.168.1.43:81;
server 192.168.1.254:81;
}
upstream ansible_slb_test {
server 192.168.1.191:81 weight=1;
server 10.1.0.101:81 weight=1;
}
server {
listen 80;
server_name test.yangtao.com;
access_log /var/log/nginx/ansible_slb_test_access.log;
error_log /var/log/nginx/ansible_slb_test_error.log;
location / {
proxy_pass http://ansible_slb_test;
}
}
server {
listen 80;
server_name web.yangtao.com;
access_log /var/log/nginx/ansible_slb_access.log;
error_log /var/log/nginx/ansible_slb_error.log;
location / {
proxy_pass http://ansible_slb;
}
}
