我这里所使用的的虚拟机地址分别为:
主机名: IP prometheus.weme 192.168.10.63 agent.weme 192.168.10.64 grafana.weme 192.168.10.65
分别进入每台虚拟机设置hostname:
hostnamectl set-hostname prometheus.weme;exit hostnamectl set-hostname agent.weme;exit hostnamectl set-hostname grafana.weme;exit #在每台虚拟机的/etc/hosts文件中加入以下内容(IP改成真实的IP地址): ip prometheus.weme ip agent.weme ip grafana.weme 192.168.10.63 prometheus.weme 192.168.10.64 agent.weme 192.168.10.65 grafana.weme
每台虚拟机同步时间:
yum install -y ntpdate ntpdate -u cn.pool.ntp.org cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime watch -n 1 date
优化每台Linux系统
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config &> /dev/null setenforce 0 systemctl stop firewalld &> /dev/null systemctl disable firewalld &> /dev/null iptables -F systemctl stop NetworkManager &> /dev/null systemctl disable NetworkManager &> /dev/null echo 1 > /proc/sys/net/ipv4/ip_forward
下载后解压就可以使用,不需要编译!

打开浏览器输入:http://192.168.10.64:9100/metrics就可以看到监控信息了
修改prometheus.yml
vim /etc/prometheus/prometheus.yml 末尾添加以下内容: - job_name: 'agent' static_configs: - targets: ['192.168.10.64:9100'] ###注意格式问题!!! 动态更新prometheus.yml配置 ps -aux | grep prometheus kill -HUP 进程号 (#如果想要更改配置而不需停止并重新启动服务,就使用此命令。)
去控制台查看 http://192.168.10.63:9090/targets
wget https://github.com/prometheus/mysqld_exporter/releases/download/v0.11.0/mysqld_exporter-0.11.0.linux-amd64.tar.gz tar xvf mysqld_exporter-0.11.0.linux-amd64.tar.gz -C /usr/local/ mv /usr/local/mysqld_exporter-0.11.0.linux-amd64/ /usr/local/mysqld_exporter #安装数据库 yum install -y mariadb-server mariadb systemctl start mariadb systemctl enable mariadb #初始化数据库 mysql_secure_installation #创建一个数据库配置文件,写上连接的用户名与密码(和上面的授权的用户名和密码要对应) vim /usr/local/mysqld_exporter/.my.cnf [client] user=用户名 password=密码 nohup /usr/local/mysqld_exporter/mysqld_exporter --config.my-cnf=/usr/local/mysqld_exporter/.my.cnf & 确认端口(9104) netstat -pantul | grep 9104
浏览器输入: http://192.168.10.64:9104/metrics就可以看到监控信息。
将此监控添加到prometheus监控软件,登录到prometheus机器。
编辑以下内容:
vim /etc/prometheus/prometheus.yml #末尾添加以下内容: - job_name: 'agent_mysql' static_configs: - targets: ['192.168.10.64:9104'] ##一定要注意格式问题!!! ps -aux | grep prometheus kill -HUP 进程号
再次去浏览器页面观察是否添加成功
http://192.168.10.63:9090/targets
wget https://dl.grafana.com/oss/release/grafana-5.3.4-1.x86_64.rpm yum install -y fontconfig urw-fonts rpm -ivh grafana-5.3.4-1.x86_64.rpm #启动 systemctl start grafana-server systemctl enable grafana-server #检查端口 netstat -pantul | grep 3000
打开浏览器输入:http://192.168.10.65:3000查看是否成功运行。
默认用户名和密码是admin和admin
首次登录grafana后系统要求更改登录密码!
至此Prometheus环境搭建成功!!
