Grafana可视化工具介绍
Grafana是一款可视化工具，大多使用在时序数据的监控方面，如同Kibana类似。Grafana的UI更加灵活，有丰富的插件，功能强大。我们在使用ClickHouse时，可以结合Grafana来监控集群状态，生成报表等。
1、Grafana软件安装
Grafana支持多种操作系统安装
Ubuntu & Debian(64 Bit)
wget https://dl.grafana.com/oss/release/grafana_6.0.1_amd64.deb
sudo dpkg -i grafana_6.0.1_amd64.deb
Redhat & Centos(64 Bit)
wget https://dl.grafana.com/oss/release/grafana-6.0.1-1.x86_64.rpm
sudo yum localinstall grafana-6.0.1-1.x86_64.rpm
Standalone Linux Binaries(64 Bit)
wget https://dl.grafana.com/oss/release/grafana-6.0.1.linux-amd64.tar.gz
tar -zxvf grafana-6.0.1.linux-amd64.tar.gz
为了方便，直接使用编译好的安装包安装，环境为Centos(64 Bit)
grafana-6.0.1.linux-amd64.tar.gz
解压到指定目录/data/grafana-6.0.1
-rw-r--r-- 1 root root 108 Oct 24 20:09 NOTICE.md

drwxr-xr-x 3 root root 4.0K Oct 24 20:17 tools
drwxr-xr-x 5 root root 4.0K Oct 24 20:17 scripts

drwxr-xr-x 2 root root 4.0K Jan 8 10:03 bin
drwxr-xr-x 3 root root 4.0K Mar 7 11:48 conf
配置文件/data/grafana-6.0.1/conf/defaults.ini基本不用修改，如果使用mysql数据库，需要修改database部分，提前装好mysql并创建库和用户
[database]
type = mysql
host = 1.1.1.1:3358
name = grafana
user = grafana_user
password =grafana_passwd
url =mysql://grafana_user:[email protected]:3358/grafana
max_idle_conn = 2
max_open_conn =
conn_max_lifetime = 14400
log_queries =
ssl_mode = disable
ca_cert_path =
client_key_path =
client_cert_path =
server_cert_name =
path = grafana.db
参见官方说明http://docs.grafana.org/installation/configuration/
2、Grafana Server 启动
/data/grafana-6.0.1/bin/grafana-server start &
INFO[03-08|15:51:12] Starting Grafana logger=server version=6.0.1 commit=0c44a04 branch=HEAD compiled=2019-03-06T22:21:49+0800

INFO[03-08|15:51:12] HTTP Server Listen logger=http.server address=0.0.0.0:3000 protocol=http subUrl= socket=
启动后，我们就可以http://localhost:3000访问页面了，如果想通过域名访问，我们可以安装nginx做代理。
3、安装nginx
下载安装包，这里只是简单安装，并没有做高可用
wget http://distfiles.macports.org/nginx/nginx-1.15.9.tar.gz
tar -xvf nginx-1.15.9.tar.gz
cd nginx-1.15.9
./configure --prefix=/usr/local/nginx
drwxr-xr-x 2 root root 4.0K Oct 26 20:57 sbin
drwx------ 2 nobody root 4.0K Oct 26 20:59 uwsgi_temp
drwx------ 2 nobody root 4.0K Oct 26 20:59 scgi_temp
drwx------ 2 nobody root 4.0K Oct 26 20:59 fastcgi_temp
drwx------ 12 nobody root 4.0K Oct 29 11:25 proxy_temp
drwxr-xr-x 2 root root 4.0K Oct 31 19:43 logs
drwxr-xr-x 2 root root 4.0K Jan 8 13:35 html
drwxr-xr-x 2 root root 4.0K Mar 7 11:46 conf
drwx------ 2 nobody root 4.0K Mar 8 14:31 client_body_temp修改配置文件vi /usr/local/nginx/conf/nginx.conf
gzip on;
upstream learnmysql.com {
server 127.0.0.1:3000 weight=10 max_fails=2 fail_timeout=30s ;
}
server {
listen 80;
server_name localhost grafana.learnmysql.com;
location / {
proxy_next_upstream http_500 http_502 http_503 http_504 error timeout invalid_header;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://learnmysql.com;
expires 0;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
测试配置文件是否正确
/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
启动nginx
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
停止nginx
/usr/local/nginx/sbin/nginx -s stop
