nginx 负载均衡代理和grafana的访问地址

按照路径/usr/local/grafana

/usr/local/nginx

按照机器：192.168.175.184

 

nginx的编译安装：
配置依赖包：
yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel gd gd-devel
tar -zxvf nginx-1.23.2.tar.gz
cd nginx-1.23.2/
./configure \

因为nginx是负载thanos-query，所以访问nginx

页面如下所示

 

按照wget https://dl.grafana.com/enterprise/release/grafana-enterprise-9.3.2-1.x86_64.rpm sudo yum install grafana-enterprise-9.3.2-1.x86_64.rpm

wget https://dl.grafana.com/enterprise/release/grafana-enterprise-9.3.2-1.x86_64.rpm

rpm -ivh grafana-enterprise-9.3.2-1.x86_64.rpm
