Nginx与Tomcat配置及限流设置指南

一、Nginx与Tomcat的配置

Nginx与Tomcat的配置主要用于前端反向代理和负载均衡，以下是常见的配置示例：

1.1 项目部署

http {
    server {
        location /xht {
            root html;
            index index.html index.htm;
            proxy_pass http://192.168.1.111:8080/xht;
        }
    }
}

1.2 限流设置

# 限流20MB，允许1000次/秒
limit_req_zone $binary_remote_addr zone=perip:20m rate=1000r/s;
# 总限流20MB，允许1000次/秒
limit_req_zone $binary_remote_addr zone=totalLimit:20m rate=1000r/s;
# 附件上传设置
location /uploadAttach.do {
    limit_conn uploadLimit 1;
    limit_rate 512k;
}

二、文件上传设置

不同大小的上传设置，适用于不同的场景：

2.1 5MB

limit_conn_zone $binary_remote_addr zone=uploadLimit:5m;
location /xht {
    root html;
    index index.html index.htm;
    proxy_pass http://192.168.1.111:8080/xht;
}
location /uploadAttach.do {
    limit_conn uploadLimit 1;
    limit_rate 512k;
}

2.2 10MB

limit_conn_zone $binary_remote_addr zone=uploadLimit:10m;
location /xht {
    root html;
    index index.html index.htm;
    proxy_pass http://192.168.1.111:8080/xht;
}
location /uploadAttach.do {
    limit_conn uploadLimit 1;
    limit_rate 512k;
}

2.3 15MB

limit_conn_zone $binary_remote_addr zone=uploadLimit:15m;
location /xht {
    root html;
    index index.html index.htm;
    proxy_pass http://192.168.1.111:8080/xht;
}
location /uploadAttach.do {
    limit_conn uploadLimit 1;
    limit_rate 512k;
}

2.4 18MB

limit_conn_zone $binary_remote_addr zone=uploadLimit:18m;
location /xht {
    root html;
    index index.html index.htm;
    proxy_pass http://192.168.1.111:8080/xht;
}
location /uploadAttach.do {
    limit_conn uploadLimit 1;
    limit_rate 512k;
}

三、高频接口配置

3.1 50r/s

limit_req_zone $binary_remote_addr zone=feqLimit:20m rate=50r/s;
location /xht {
    root html;
    index index.html index.htm;
    proxy_pass http://192.168.1.111:8080/xht;
}
location /login_gis/loginVerify.do {
    limit_req zone=feqLimit burst=50;
}
location /userLogin.do {
    limit_req zone=feqLimit burst=50;
}
location /sendXhyPos.do {
    limit_req zone=feqLimit burst=50;
}
location /getMessage.do {
    limit_req zone=feqLimit burst=50;
}

3.2 100r/s

limit_req_zone $binary_remote_addr zone=feqLimit:20m rate=100r/s;
location /xht {
    root html;
    index index.html index.htm;
    proxy_pass http://192.168.1.111:8080/xht;
}
location /login_gis/loginVerify.do {
    limit_req zone=feqLimit burst=100;
}
location /userLogin.do {
    limit_req zone=feqLimit burst=100;
}
location /sendXhyPos.do {
    limit_req zone=feqLimit burst=100;
}
location /getMessage.do {
    limit_req zone=feqLimit burst=100;
}

3.3 150r/s

limit_req_zone $binary_remote_addr zone=feqLimit:20m rate=150r/s;
location /xht {
    root html;
    index index.html index.htm;
    proxy_pass http://192.168.1.111:8080/xht;
}
location /login_gis/loginVerify.do {
    limit_req zone=feqLimit burst=150;
}
location /userLogin.do {
    limit_req zone=feqLimit burst=150;
}
location /sendXhyPos.do {
    limit_req zone=feqLimit burst=150;
}
location /getMessage.do {
    limit_req zone=feqLimit burst=150;
}

3.4 200r/s

limit_req_zone $binary_remote_addr zone=feqLimit:20m rate=200r/s;
location /xht {
    root html;
    index index.html index.htm;
    proxy_pass http://192.168.1.111:8080/xht;
}
location /login_gis/loginVerify.do {
    limit_req zone=feqLimit burst=200;
}
location /userLogin.do {
    limit_req zone=feqLimit burst=200;
}
location /sendXhyPos.do {
    limit_req zone=feqLimit burst=200;
}
location /getMessage.do {
    limit_req zone=feqLimit burst=200;
}
