登录控制台 localhost:9090,登录界面如下：
3、mysql_exporter部署 1 2 3 wget https://github.com/prometheus/mysqld_exporter/releases/download/v0.11.0/mysqld_exporter-0.11.0.linux-amd64.tar.gz tar -zxvf mysqld_exporter-0.11.0.linux-amd64.tar.gz cd mysqld_exporter-0.11.0.linux-amd64/
配置连接数据库文件
1 2 3 4 5 cat .my.cnf [client] host = 127.0.0.1 user=root password=12345678
启动mysqld_exporter
1 2 3 4 5 6 7 8 9 10 11 ./mysqld_exporter --config.my-cnf="/data/soft/mysqld_exporter-0.11.0.linux-amd64/.my.cnf" ---- INFO[0000] Starting mysqld_exporter (version=0.11.0, branch=HEAD, revision=5d7179615695a61ecc3b5bf90a2a7c76a9592cdd) source="mysqld_exporter.go:206" INFO[0000] Build context (go=go1.10.3, user=root@3d3ff666b0e4, date=20180629-15:00:35) source="mysqld_exporter.go:207" INFO[0000] Enabled scrapers: source="mysqld_exporter.go:218" INFO[0000] --collect.global_status source="mysqld_exporter.go:222" INFO[0000] --collect.global_variables source="mysqld_exporter.go:222" INFO[0000] --collect.slave_status source="mysqld_exporter.go:222" INFO[0000] --collect.info_schema.tables source="mysqld_exporter.go:222" INFO[0000] Listening on :9104 source="mysqld_exporter.go:232" ----
查看进程是否启动正常：
1 netstat -tunlp|grep 9104
登录web界面,http://localhost:9104/
1 2 3 4 5 - job_name: mysql static_configs: - targets: ['127.0.0.1:9104'] labels: instance: test
备注:
重新启动prometheus，进入prometheus控制台，点击status->target
4、添加数据源
5、下载仪表盘 https://github.com/percona/grafana-dashboards/tree/master/dashboards
6、mongodb_exporter部署用于监控mongodb prometheus监控mongodb数据库，安装之前需要配置go环境下载配置go环境
1 2 wget https://dl.google.com/go/go1.11.linux-amd64.tar.gz tar -C /usr/local -xzf go1.11.linux-amd64.tar.gz
添加环境变量
1 2 3 echo " GOPATH=$HOME/go export PATH=$PATH:$GOPATH/bin" >> ~/.bash_profile
使配置的环境变量生效
创建配置mognodb所需要的目录
1 mkdir -p $HOME/go/{dir,src,pkg}
安装glide
1 curl https://glide.sh/get | sh
安装mongodb-exporter
1 2 3 git clone git@github.com:dcu/mongodb_exporter.git $GOPATH/src/github.com/dcu/mongodb_exporter cd $GOPATH/src/github.com/dcu/mongodb_exporter make build
查看mongdob_exporter使用的参数
启动mongodb_exporter,获取数据库的数据
1 ./mongodb_exporter -mongodb.uri mongodb://localhost:30000
启动端口默认为9001,登录http://localhost:9001，查看是否正常
1 2 3 - job_name: mongodb static_configs: - targets: ['127.0.0.1:9001']
重启premetheus,登录premetheus控制台查看获取mognodb是否正常链接 ，跳转到mongodb_exporter模板
7、redis_exporter部署用于监控redis,安装redis-exporter模板 1 2 3 go get github.com/oliver006/redis_exporter cd $GOPATH/src/github.com/oliver006/redis_exporter go build
启动redis_exporter进程获取redis数据(默认进程端口号位9121)
1 ./redis_exporter -redis.addr redis://127.0.0.1:6379 -redis.password test
启动端口默认为9001,登录http://localhost:9121，查看是否正常
1 2 3 - job_name: redis static_configs: - targets: ['127.0.0.1:9121']
重启premetheus,登录premetheus控制台查看获取redis是否正常此处 跳转到redis_exporter链接
