通过 yum 安装 Ganglia 监控

通过 yum 安装 Ganglia 监控

2018/07/10 运维 监控 Ganglia

环境说明

  • Server 端 IP 为 192.168.1.61
  • Client 端 IP 为 192.168.1.62
  • 主机操作系统为 rhel-server-7.2-x86_64
  • Yum 源为本地 ISO 挂载镜像

设置固定 IP

  • 查询网络状态 mncli dev

  • 编辑 /etc/sysconfig/network-scripts 目录下的 ifcfg-eno16777736 文件

      BOOTPROTO=static #启用静态IP地址  若是dhcp 则是动态获取ip
  ONBOOT=yes   #开启自动启用网络连接
  IPADDR=地址
  NETMASK=掩码
  GATEWAY=网关
  DNS1=DNS地址
  • 通过 systemctl restart network 重启网络服务

关闭防火墙和 SELinux

systemctl stop firewalld.service
systemctl disable firewalld.service
systemctl stop iptables.service
systemctl disable iptables.service
setenforce 0

将 /etc/selinux/config 文件中的 SELINUX=enforcing 修改为 SELINUX=disabled

安装 Ganglia 服务

Server 端程序安装

  1. 安装 rpmbuild 所需要的相关依赖

     yum install freetype-devel rpm-build php httpd libpng-devel libart_lgpl-devel python-devel pcre-devel autoconf automake libtool expat-devel rrdtool-devel apr-devel gcc-c++ make pkgconfig -y    

     yum install https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libconfuse-2.7-7.el7.x86_64.rpm -y

     yum install https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libconfuse-devel-2.7-7.el7.x86_64.rpm -y

     yum install http://mirrors.sohu.com/centos/7/os/x86_64/Packages/libart_lgpl-devel-2.3.21-10.el7.x86_64.rpm -y

     yum install http://mirrors.sohu.com/centos/7/os/x86_64/Packages/rrdtool-devel-1.4.8-9.el7.x86_64.rpm -y

  2. 下载 ganglia 源码包

     wget http://downloads.sourceforge.net/project/ganglia/ganglia%20monitoring%20core/3.7.2/ganglia-3.7.2.tar.gz

  3. rpm build

     rpmbuild -tb ganglia-3.7.2.tar.gz

    编译完成之后，rpm 包存放的目录为 /root/rpmbuild/RPMS/x86_64/

    目录中的内容为

     ganglia-debuginfo-3.7.2-1.x86_64.rpm
 ganglia-devel-3.7.2-1.x86_64.rpm
 ganglia-gmetad-3.7.2-1.x86_64.rpm
 ganglia-gmond-3.7.2-1.x86_64.rpm
 ganglia-gmond-modules-python-3.7.2-1.x86_64.rpm
 libganglia-3.7.2-1.x86_64.rpm

  4. 安装 rpm 包

     yum install /root/rpmbuild/RPMS/x86_64/*.rpm -y

Client 端程序安装

  1. 将在 Server 端编译的客户端 rpm 包拷贝到 Client 端

     # Server 端操作
 scp /root/rpmbuild/RPMS/x86_64/*.rpm root@192.168.1.62:/root/ganglia/

  2. 删除 Client 端的 gmetad

     # Client 端操作
 rm -f /root/ganglia/ganglia-gmetad-3.7.2-1.x86_64.rpm

  3. 安装 Client 端需要的依赖

     # Client 端操作
 yum install https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libconfuse-2.7-7.el7.x86_64.rpm -y

     # Client 端操作
 yum install https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/l/libconfuse-devel-2.7-7.el7.x86_64.rpm -y

  4. 安装 Client 端程序

     # Client 端操作
 yum install /root/ganglia/*.rpm -y

Server 端程配置文件

  • 编辑 /etc/ganglia/gmetad.conf

    将 data_source "my cluster" localhost 修改成为 data_source "bonc" 1 localhost

      #data_source "my cluster" localhost
  data_source "bonc" 1 localhost

  • 编辑 /etc/ganglia/gmond.conf

    对配置文件做类似如下内容的变更

      ... ...
    
  /*
   * The cluster attributes specified will be used as part of the <CLUSTER>
   * tag that will wrap all hosts collected by this instance.
   */
  cluster {
  #  name = "unspecified"
    name = "bonc"
    owner = "unspecified"
    latlong = "unspecified"
    url = "unspecified"
  }
    
  /* The host section describes attributes of the host, like the location */
  host {
    location = "unspecified"
  }
    
  /* Feel free to specify as many udp_send_channels as you like.  Gmond
     used to only support having a single channel */
  udp_send_channel {
    #bind_hostname = yes # Highly recommended, soon to be default.

                         # that resolves to the machine's hostname.  Without
                         # this, the metrics may appear to come from any

  udp_send_channel {
    host = 192.168.1.62
    port = 8649
    ttl = 1
  }
    
  /* You can specify as many udp_recv_channels as you like as well. */
  udp_recv_channel {
  #  mcast_join = 239.2.11.71
    port = 8649
  #  bind = 239.2.11.71
    retry_bind = true
    # Size of the UDP buffer. If you are handling lots of metrics you really
    # should bump it up to e.g. 10MB or even higher.
    # buffer = 10485760
  }
    
  /* You can specify as many tcp_accept_channels as you like to share
     an xml description of the state of the cluster */
  tcp_accept_channel {
    port = 8649
    # If you want to gzip XML output
    gzip_output = no
  }
    
  /* Channel to receive sFlow datagrams */
  #udp_recv_channel {
  #  port = 6343
  #}
    
  /* Optional sFlow settings */
  #sflow {
  # udp_port = 6343
  # accept_vm_metrics = yes
  # accept_jvm_metrics = yes
  # multiple_jvm_instances = no
  # accept_http_metrics = yes
  # multiple_http_instances = no
  # accept_memcache_metrics = yes
  # multiple_memcache_instances = no
  #}
    
  ... ...

Client 端程配置文件

  • 编辑 /etc/ganglia/gmond.conf

    对配置文件做类似如下内容的变更，更改的内容和 Server 端一致

    owner = "unspecified"
    latlong = "unspecified"
    url = "unspecified"
  }
    
  /* The host section describes attributes of the host, like the location */
  host {
    location = "unspecified"
  }
    
  /* Feel free to specify as many udp_send_channels as you like.  Gmond

  udp_send_channel {
