性能测试监控平台搭建-nginx_exporter（八）
8.安装nginx_exporter
8.1 安装nginx（二进制安装）
8.1.1 安装nginx的相关依赖包
[root@master ~]# yum install -y gcc-c++ zlib zlib-devel openssl openssl-devel pcre pcre-devel
8.1.2 下载nginx的tar包
下载nginx的tar包后解压
[root@master ~]# cd /opt/tgz
[root@master tgz]# wget http://nginx.org/download/nginx-1.24.0.tar.gz
[root@master tgz]# tar -zxvf nginx-1.24.0.tar.gz
下载ngx_devel_kit的zip包后解压
[root@master ~]# cd /opt/tgz
[root@master tgz]# wget https://github.com/vision5/ngx_devel_kit/archive/refs/tags/v0.3.3.zip
[root@master tgz]# unzip v0.3.3.zip
8.1.3 编译安装nginx
# 选择安装nginx的相关组件
[root@master tgz]# cd nginx-1.24.0
[root@master nginx-1.24.0]# ./configure --prefix=/usr/local/nginx-1.24.0 \
> --add-module=../ngx_devel_kit-0.3.3 \
> --with-http_stub_status_module \
> --with-http_ssl_module \
> --with-file-aio \
> --with-http_realip_module \
> --with-http_gzip_static_module
# 编译
[root@master nginx-1.24.0]# make
# 编译安装
[root@master nginx-1.24.0]# make install
8.1.4 开启nginx的stub_status配置
[root@master ~]# cd /usr/local/nginx-1.24.0
[root@master nginx-1.24.0]# vim conf/nginx.conf
在 nginx.conf文件中，在server的配置项内，添加 nginx_status{}的配置项目
…………………………………………
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location /status {
stub_status;
access_log off;
allow all;
# allow 10.0.0.0/24;
# deny all;
}
location / {
root html;
index index.html index.htm;
}
#error_page 404 /404.html;
…………………………………………
完成配置修改后，让nginx重新加载配置文件
[root@master nginx-1.24.0]# sbin/nginx -s reload
在浏览器中输入 http://10.0.0.100/status 展示内容如下
8.2 安装nginx-prometheus-exporter
8.2.1 下载对应的的 nginx-prometheus-exporter 的tar包
官方下载地址： https://github.com/nginxinc/nginx-prometheus-exporter/releases
下载nginx-prometheus-exporter
[root@master ~]# cd /opt/tgz
[root@master tgz]# wget https://github.com/nginxinc/nginx-prometheus-exporter/releases/download/v1.3.0/nginx-prometheus-exporter_1.3.0_linux_amd64.tar.gz
8.2.2 安装nginx-prometheus-exporter
解压 nginx-prometheus-exporter的tar包
[root@master ~]# mkdir -p /opt/app/nginx-prometheus-exporter
[root@master ~]# cd /opt/tgz
[root@master tgz]# cp nginx-prometheus-exporter_1.3.0_linux_amd64.tar.gz /opt/app/nginx-prometheus-exporter/.
[root@master tgz]# cd /opt/app/nginx-prometheus-exporter
[root@master nginx-prometheus-exporter]# tar zxvf nginx-prometheus-exporter_1.3.0_linux_amd64.tar.gz
[root@master nginx-prometheus-exporter]# rm -f nginx-prometheus-exporter_1.3.0_linux_amd64.tar.gz
[root@master nginx-prometheus-exporter]# cd ..
[root@master app]# chown -R root:root nginx-prometheus-exporter
创建nginx_exporter的系统启动文件
[root@master ~]# vim /usr/lib/systemd/system/nginx_exporter.service
文件内容如下，需要监控的 ip地址换成nginx开启status的服务地址
