本文主要介紹了Nginx配置Prometheus監(jiān)控的實現(xiàn),文中通過示例代碼介紹的非常詳細,對大家的學習或者工作具有一定的參考學習價值,需要的朋友們下面隨著小編來一起學習學習吧

安裝包下載，注意下載nginx版本需要和生產(chǎn)環(huán)境保持一致

wget https://github.com/vozlt/nginx-module-vts/archive/refs/tags/v0.2.2.tar.gz
wget https://github.com/hnlq715/nginx-vts-exporter/releases/download/v0.10.3/nginx-vts-exporter-0.10.3.linux-amd64.tar.gz
wget http://nginx.org/download/nginx-1.26.2.tar.gz

解壓nginx-module-vts

tar -xf /opt/v0.2.2.tar.gz -C /usr/local/src/

查看運行nginx編譯參數(shù)

nginx -V

./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-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --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-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_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-google_perftools_module --with-debug --with-cc-opt='-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/generic-hardened-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -specs=/usr/lib/rpm/generic-hardened-ld -Wl,-E'

安裝編譯環(huán)境

yum install pcre-devel openssl-devel libxml2-devel libxslt-devel gd-devel gperftools gperftools-devel

解壓nginx源碼

tar xf nginx-1.26.2.tar.gz

再原來編譯參數(shù)基礎(chǔ)上添加vts模塊，進行編譯

./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-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --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-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_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-google_perftools_module --with-debug --with-cc-opt='-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/generic-hardened-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -specs=/usr/lib/rpm/generic-hardened-ld -Wl,-E' --add-module=/usr/local/src/nginx-module-vts-0.2.2/
make

備份nginx配置文件

cd /usr/local/nginx/conf
cp nginx.conf nginx.conf.bak

nginx配置文件添加配置

#在nginx.conf http塊添加如下配置
vhost_traffic_status_filter_by_host on;
vhost_traffic_status_zone;
server {
   listen 8089;
    location /status {
     vhost_traffic_status_display;
     vhost_traffic_status_display_format html;
}
}

將so文件替換

cd /usr/lib64/nginx/modules/
mkdir backup
mv ./* backup/
cp /root/nginx-1.26.2/objs/*.so .

替換nginx二進制文件，并啟動nginx

#先備份二進制文件
cd /usr/local/nginx/sbin
cp nginx nginx.20241206
#停止nginx，不然新的二進制文件覆蓋不了
systemctl stop nginx
#替換二進制文件
cp /root/nginx-1.20.2/nginx-1.20.2/objs/nginx .
#檢查配置文件語法
./nginx -t
#啟動Nginx
systemctl start nginx

部署exporter

tar -xf nginx-vts-exporter-0.10.3.linux-amd64.tar.gz
cp /opt/nginx-vts-exporter-0.10.3.linux-amd64/nginx-vts-exporter /usr/local/bin/
