本文说下监控nginx,prometheus grafana nginx 安装配置和使用

是真不知道配置的路径在哪,找了好久,最后路径在容器中的/opt/bitnami/mysqld-exporter/
因为容器中没有配置的,需要自己配置.my.cnf文件,然后挂载到容器中
[client]
host=10.xxx.xx.xxx
port=3306
user=exporter_xxx
password=xxx_432DERF

我用的是上面的。
https://hub.docker.com/r/prom/mysqld-exporter/tags
docker pull prom/mysqld-exporter:v0.15.0
docker run -itd --name mysqld-exporter --restart=always -p 9104:9104 -v /etc/localtime:/etc/localtime:ro -v /home/docker_data/monitor/mysqld-exporter/promconf/.my.cnf:/.my.cnf prom/mysqld-exporter:v0.15.0
CREATE USER ‘exporter’@‘localhost’ IDENTIFIED BY ‘expoter12Ssdc3’ WITH MAX_USER_CONNECTIONS 3;
GRANT PROCESS, REPLICATION CLIENT, SELECTON . TO ‘exporter’@‘localhost’;
FLUSH PRIVILEGES;
.my.cnf配置,同样要有
网上有很多在docker启动时,指定mysql数据源的,结果是报错。
还有一种情况是DB连接拒绝,具体情况具体分析,和服务器和网络配置有关系
[client]
host=10.xxx.xx.xxx
port=3306
user=exporter_xxx
password=xxx_432DERF
