如何使用Nginx对Artifactory进行http应用

在我们日常使用高可用集群时,都会使用到负载均衡工具对多个节点的负载进行转发。这里就不得不提到我们常用的一个负载均衡工具Nginx,Nginx官方提供的免费版本功能相对简单,大部分情况下我们都是用其进行负载均衡,对于应用的状态主要是依赖于其他的监控工具。如果对于小型的团队来说,部署专门的监控工具还需要资源,使用Nginx对应用进行探活监控可以节约这部分成本。

首先安装Nginx

使用yum安装nginx我这里使用的是1.16.1版本

yum install nginx

安装完成后可以获取源码安装命令

nginx -V

安装Nginx探活插件

下载源码与探活插件

wget https://nginx.org/download/nginx-1.16.1.tar.gz

wget https://github.com/yaoweibin/nginx_upstream_check_module/archive/refs/heads/master.zip

Nginx使用源码编译安装相关的依赖包

yum install pcre pcre-devel openssl openssl-devel gd gd-devel zlib patch libxml2-devel libxslt-devel perl-devel perl-ExtUtils-Embed perl zlib-devel patch

解压源码和插件包,我这里将两个软件包全部放到/opt下面进行解压

tar zxvf nginx-1.16.1.tar.gz

unzip nginx_upstream_check_module.zip

patch探活插件到Nginx源码中

cd /opt/nginx-1.16.1

patch -p1 < /opt/nginx_upstream_check_module-master/check_1.16.1+.patch

执行源码编译安装,添加http探活插件

使用Nginx负载Artifactory

Nginx可以作为Artifactory制品库的负载均衡器,用来负载Artifactory多个节点间的请求,Artifactory也可以自动生成Nginx配置文件,具体操作参考下图

配置探活

生成配置文件后,使用探活插件的配置方法,在Nginx的config 文件中进行配置。具体样例如下:

upstream artifactory {

server 192.168.1.2:8082;

server 192.168.1.3:8082;

check interval=2000 rise=2 fall=2 timeout=1000 type=http;

check_http_send “HEAD / HTTP/1.0\r\n\r\n”;

check_http_expect_alive http_2xx http_3xx

}

upstream artifactory-direct {

server 192.168.1.2:8081;

server 192.168.1.3:8081;

check interval=2000 rise=2 fall=2 timeout=1000 type=http;

check_http_send “HEAD / HTTP/1.0\r\n\r\n”;

check_http_expect_alive http_2xx http_3xx

}

server {

 

listen 80 ;

 

server_name artifactory.external.io;

if ($http_x_forwarded_proto = ”) {

set $http_x_forwarded_proto  $scheme;

}

## Application specific logs

## access_log /var/log/nginx/artifactory.external.io -access.log timing;

## error_log /var/log/nginx/artifactory.external.io -error.log;

rewrite ^/$ /ui/ redirect;

rewrite ^/ui$ /ui/ redirect;

chunked_transfer_encoding on;

client_max_body_size 0;

location / {

proxy_read_timeout  2400s;

proxy_pass_header   Server;

proxy_cookie_path   ~*^/.* /;

proxy_buffer_size 128k;

proxy_buffers 40 128k;

proxy_busy_buffers_size 128k;

proxy_pass          http://artifactory;

proxy_set_header    X-JFrog-Override-Base-Url $http_x_forwarded_proto://$host:$server_port;

proxy_set_header    X-Forwarded-Port  $server_port;

proxy_set_header    X-Forwarded-Proto $http_x_forwarded_proto;

proxy_set_header    Host              $http_host;

proxy_set_header    X-Forwarded-For   $proxy_add_x_forwarded_for;

 

location ~ ^/artifactory/ {

proxy_pass    http://artifactory-direct;

}

}

location /status {

check_status;

access_log   off;

}

}

探活配置成功之后访问,预置的location可以看到当前负载应用节点的健康状态

 

并且还支持json格式查看,方便我们进行数据采集
