拿nginx做负载均衡
情况是这样的现在有两台机子有一模一样的服务,需要用nginx做负载均衡。
平时项目里面某个请求的地址是这样的
http://127.0.0.1:13014/FaceRetrieveService/SearchFace
所以我们可以用nginx这样做负载均衡

user nginx;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {

}
http {

upstream go-faceURL {
server 127.0.0.1:13014;

ip_hash;
}
server {

# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
#人脸识别接口
location /faceURL {
proxy_set_header Host $host; #notice:very important(注�~D~O)
proxy_set_header X-Real-IP $remote_addr; #notice:very important(注�~D~O)
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #notice:very important(注�~D~O)
proxy_pass http://go-faceURL/FaceRetrieveService/SearchFace;
}
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}
这样子项目里面请求地址就可以变成这样
http://172.18.132.42/faceURL
nginx会识别go-XXX的文字然后把前面的地址拿一个来替换这个go-XXX的位置
