1.安装grafana
#####gafana过期安装包安装报错
Error unpacking rpm package grafana-5.1.4-1.x86_64
error: unpacking of archive failed on file /usr/sbin/grafana-cli;5e250e9c: cpio: read

原因安装包损坏不是最新的
######下载官网最新的包：
####grafana installer
https://grafana.com/grafana/download
#####binary install
wget https://dl.grafana.com/oss/release/grafana-6.5.3.linux-amd64.tar.gz
tar -zxvf grafana-6.5.3.linux-amd64.tar.gz
#### grafana rpm install
sudo yum install initscripts urw-fonts wget
wget <rpm package url>
sudo rpm -Uvh <local rpm package>

### NOT starting on installation, please execute the following statements to configure grafana to start automatically using systemd
sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable grafana-server.service
### You can start grafana-server by executing
sudo /bin/systemctl start grafana-server.service
POSTTRANS: Running script.............
#### 启动grafana，验证服务已启动
sudo systemctl daemon-reload
sudo systemctl start grafana-server
sudo systemctl status grafana-server
###启动成功验证：

Docs: http://docs.grafana.org
Main PID: 63048 (grafana-server)
###配置开机自启动
sudo systemctl enable grafana-server.service
####防火墙开放grafana端口默认3000:
firewall-cmd --zone=public --add-port=3000/tcp --permanent
firewall-cmd --reload
firewall-cmd --zone=public --list-ports
或者直接停掉防火墙：
systemctl stop firewalld
###web访问grafana:
安装主机ip:3000
###修改grafana 配置,Grafana有许多配置选项，您可以在.ini配置文件中指定或使用环境变量指定,
您必须重新启动Grafana才能使所有配置更改生效。
官网doc文档地址：https://grafana.com/docs/grafana/latest/installation/configuration/
vi /etc/grafana/grafana.ini
###ini注释comment方法讲解：
所有注释以分号开头，如果需要更改配置比如web页面port ,
需要删除行前面分号，更改为
###关于web login密码账号更改也是如此，需要重启grafana才生效
37 # The http port to use
38 ;http_port = 3000
####web login

#####influxdb 启动失败问题解决，influxdb installer 配置路径：
/etc/influxdb/influxdb.conf
#####启用graphite配置########：
[[graphite]]
# Determines whether the graphite endpoint is enabled.
enabled = false
database = "graphite"
# retention-policy = ""
bind-address = ":2003"
protocol = "tcp"
consistency-level = "one"
http启用：
### [http]
###
### Controls how the HTTP endpoints are configured. These are the primary
### mechanism for getting data into and out of InfluxDB.
###
[http]
# Determines whether HTTP endpoint is enabled.
enabled = true
# The bind address used by the HTTP service.
bind-address = ":8086"
#### 默认influxdb数据存放：meta元数据,data
/var/lib/influxdb/data
/var/lib/influxdb/meta
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
### [meta]
###
### Controls the parameters for the Raft consensus group that stores metadata
### about the InfluxDB cluster.
###
[meta]
# Where the metadata/raft database is stored
dir = "/var/lib/influxdb/meta"
# Automatically create a default retention policy when creating a database.
# retention-autocreate = true
# If log messages are printed for the meta service
# logging-enabled = true
###
### [data]
###
### Controls where the actual shard data for InfluxDB lives and how it is
### flushed from the WAL. "dir" may need to be changed to a suitable place
### for your system, but the WAL settings are an advanced configuration. The
### defaults should work for most systems.
###
[data]
# The directory where the TSM storage engine stores TSM files.
dir = "/var/lib/influxdb/data"
# The directory where the TSM storage engine stores WAL files.
wal-dir = "/var/lib/influxdb/wal"
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
#### influxdb log目录：
启动influxdb:systemctl start influxdb
查询启动状态：systemctl status influxdb
启动失败：
: Failed to start InfluxDB is an open-source, distributed, time series database.
tail -n 20 /var/log/messages 分析失败原因，查找到用户权限拒绝：
run: open server: open tsdb store: mkdir /var/lib/influxdb/data/_internal/_series: permission denied
#### 查询influxdb: 使用查询命令rpm -ql influxdb
/usr/lib/influxdb/scripts/influxdb.service
/var/lib/influxdb
/var/log/influxdb
####
ls -l -d influxdb
cd /var/lib/
chown -R influxdb:influxdb influxdb
#### influxdb 集成安装collectd 监控cpu，mem,disk
###yum 安装collectd：org：https://collectd.org/download.shtml
<<python 模块伪代码https://www.jianshu.com/p/a05da23150fb>>
####### collectd安装使用，官网地址：https://collectd.org/download.shtml
方法一yum安装：
yum install epel-release–y
yum install -y collectd
###修改配置：
vi /etc/collectd.conf
修改配置
vi /etc/collectd.conf
确保以下几项的注释（#）是去掉的
Hostname "192.168.1.126" 此处改为安装collectd的机器IP地址
LoadPlugin cpu
LoadPlugin memory
LoadPlugin network
LoadPlugin swap
<Plugin cpu>
ReportByCpu true
ReportByState true
ValuesPercentage true 此处启用cpu的使用率，5.7.*以上才有，低版本的不支持百分百
</Plugin>
<Plugin network>
<Server "192.168.1.222" "25826"> 此处指定将collectd收集的数据发送到的influxdb地址和influxdb conf里collectd配置的端口
# Interface "enp0s31f6" 通过ifconfig获取网卡的名称
</Server>
</Plugin>
启动：
systemctl start collectd.service
systemctl status collectd.service
