一、原因

因客户Red Hat 7.5服务器安装部署grafana无法添加prometheus数据源&＃xff0c;以及无法修改初始密码&＃xff0c;为确保环境访问安全&＃xff0c;特别研究通过账号密码认证访问prometheus&＃xff0c;百度了很多资料&＃xff0c;但都缺这缺那&＃xff0c;所以我这里记录下具体实现过程&＃xff1a;

二、安装部署httpd

方法一&＃xff1a;使用yum安装

yum -y install apr apr-util httpd

方法二&＃xff1a;使用源码安装

yum -y install expat-devel gcc gcc-c&＃43;&＃43; autoreconf libtoolize automake

1、下载httpd安装包

wget http://mirrors.hust.edu.cn/apache/httpd/httpd-2.4.46.tar.gz

2、解压

tar zxvf httpd-2.4.46.tar.gz

3、下载新的apr、apr-util安装(安装过程会有各种奇葩错误&＃xff0c;自行百度解决&＃xff0c;这里不具体讲解)

wget http://mirror.bit.edu.cn/apache/apr/apr-1.7.0.tar.gz wget http://mirror.bit.edu.cn/apache/apr/apr-util-1.6.1.tar.gz

4、安装apr、apr-util

tar -zxvf apr-1.7.0.tar.gz tar -zxvf apr-util-1.6.1.tar.gzcd apr-1.7.0./configure --prefix&＃61;/usr/local/apr && make && make installc./configure --prefix&＃61;/usr/local/apr-util && make && make install

5、进入目录cd httpd-2.4.46/

cd /opt/httpd-2.4.46/./configure --prefix&＃61;/usr/local/apache2/ --enable-rewrite --enable-so --with-apr&＃61;/usr/local/apr --with-apr-util&＃61;/usr/local/apr-utilmake && make install

三、创建prometheus访问认证账号密码

备注&＃xff1a;路径与用户名及密码根据实际环境操作变更(在交互界面输入两次相同的密码)

/usr/bin/htpasswd -c /etc/nginx/.htpasswd promethues

四、配置nginx访问配置

vim /etc/nginx/conf/nginx.conf location / { auth_basic "Prometheus"; auth_basic_user_file /etc/nginx/.htpasswd; proxy_pass http://localhost:9090; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; root html; index index.html index.htm; }/etc/nginx/sbin/nginx -t/etc/nginx/sbin/nginx -s reload

五、修改prometheus.yml文件&＃xff0c;配置basic auth认证

1、修改prometheus.yml文件

vim /usr/local/prometheus/prometheus.yml - job_name: &＃39;prometheus&＃39; # metrics_path defaults to &＃39;/metrics&＃39; # scheme defaults to &＃39;http&＃39;. static_configs: - targets: [&＃39;localhost:9090&＃39;] basic_auth: username: promethues password: 密码

2、重启prometheus服务

systemctl restart prometheussystemctl status prometheus

3、访问prometheus服务界面

4、输入配置的用户名与认证密码

5、查看targets信息
