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 ./configure \ --prefix=/usr/share/nginx \ --sbin-path=/usr/sbin/nginx \ --modules-path=/usr/lib64/nginx/modules \ --conf-path=/etc/nginx/nginx.conf \ --error-log-path=/var/log/nginx/error.log \ --http-log-path=/var/log/nginx/access.log \ --http-client-body-temp-path=/var/lib/nginx/tmp/client_body \ --http-proxy-temp-path=/var/lib/nginx/tmp/proxy \ --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi \ --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi \ --http-scgi-temp-path=/var/lib/nginx/tmp/scgi \ --pid-path=/run/nginx.pid \ --lock-path=/run/lock/subsys/nginx \ --user=nginx \ --group=nginx \ --with-file-aio \ --with-ipv6 \ --with-http_ssl_module \ --with-http_v2_module \ --with-http_realip_module \ --with-stream_ssl_preread_module \ --with-http_addition_module \ --with-http_xslt_module=dynamic \ --with-http_image_filter_module=dynamic \ --with-http_sub_module \ --with-http_dav_module \ --with-http_flv_module \ --with-http_mp4_module \ --with-http_gunzip_module \ --with-http_gzip_static_module \ --with-http_random_index_module \ --with-http_secure_link_module \ --with-http_degradation_module \ --with-http_slice_module \ --with-http_stub_status_module \ --with-http_perl_module=dynamic \ --with-http_auth_request_module \ --with-mail=dynamic \ --with-mail_ssl_module \ --with-pcre \ --with-pcre-jit \ --with-stream=dynamic \ --with-stream_ssl_module \ --with-debug \ --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' \ --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E' \ --add-module=/opt/nginx_upstream_check_module-master/ 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
