51工具盒子利用Grafana的API Key+Nginx反向代理实现Grafana免登录访问
需求背景：
- 1、无需提供密码给用户，可以让用户直接浏览器免登录访问Grafana大屏
- 2、并且用户只有浏览的权限，无法配置Grafana及修改配置
- 3、直接80端口访问grafana,无需访问grafana默认的3000端口
基于以上几个要求，通过搜索引擎查询相关文章，总结出具体的实现步骤
一、修改/etc/grafana/grafana.ini
/etc/grafana/grafana.ini配置文件修改，允许嵌入
cat /etc/grafana/grafana.ini | grep allow_embedding
sed -i "s/;allow_embedding = false/allow_embedding = true/g" /etc/grafana/grafana.ini
cat /etc/grafana/grafana.ini | grep allow_embedding
systemctl restart grafana-server
二、Granfana添加API Key
拷贝一下生成的API Key
eyJrIjoiRnJjVmNURW1vdnlxQkdOTExqM29DcnJJV3g4TnQ0SEwiLCJuIjoid2Vidmlld2VyIiwiaWQiOjF9
curl -H "Authorization: Bearer eyJrIjoiRnJjVmNURW1vdnlxQkdOTExqM29DcnJJV3g4TnQ0SEwiLCJuIjoid2Vidmlld2VyIiwiaWQiOjF9" http://192.168.31.170:3000/api/dashboards/home
三、配置nginx的yum源并安装配置nginx
1、配置nginx的yum源并安装nginx
cat > /etc/yum.repos.d/nginx.repo << \EOF
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
EOF
yum install nginx -y
2、【可选】修改默认的nginx配置文件nginx.conf
可以自行修改为json格式的格式日志数据输出
[root@centos nginx]# cat nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log notice;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
# log_format main '$remote_addr - $remote_user \[$time_local\] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
# access_log /var/log/nginx/access.log main;
log_format json_analytics escape=json '{'

'}';
access_log /var/log/nginx/access.log json_analytics;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
}
输出的json日志美化后的效果如下
3、添加grafana反向代理配置
cd /etc/nginx/conf.d/
mv default.conf /opt/
vim backend_grafana.conf
# 添加如下配置，其中API Key为上一步中的grafana api_key
upstream grafana_server {
server 127.0.0.1:3000;
}
server {
listen 80;
server_name localhost;
location / {
proxy_buffer_size 128k;
proxy_buffers 32 128k;
proxy_busy_buffers_size 128k;
add_header Access-Control-Allow-Origin '*';
add_header Access-Control-Allow-Methods '*';
add_header Access-Control-Allow-Credentials true;
#add_header Access-Control-Allow-Headers Authorization;
set $auth 'Bearer eyJrIjoiRnJjVmNURW1vdnlxQkdOTExqM29DcnJJV3g4TnQ0SEwiLCJuIjoid2Vidmlld2VyIiwiaWQiOjF9';
proxy_set_header Host $host;
proxy_set_header Authorization $auth;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://grafana_server/;
}
}
systemctl enable nginx
systemctl start nginx
firewall-cmd --permanent --zone=public --add-port=80/tcp
firewall-cmd --reload
四、测试免登录效果
直接80端口访问grafana且无需输入账号密码
http://192.168.31.170
五、Tips
1、当然你也可以使用firewalld的rich-rule来控制访问80端口的来源IP
具体步骤
firewall-cmd --permanent --zone=public --remove-port=80/tcp
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address='192.168.31.100' port port="80" protocol="tcp" accept'
firewall-cmd --reload

例如192.168.31.60 访问grafana 80端口直接拒绝
curl -H "Authorization: Bearer eyJrIjoiRnJjVmNURW1vdnlxQkdOTExqM29DcnJJV3g4TnQ0SEwiLCJuIjoid2Vidmlld2VyIiwiaWQiOjF9" http://192.168.31.170/api/dashboards/home
