實戰ganglia分佈式的監控系統（1）——監控主機與遠程主機

        ganglia 是分佈式的監控系統,有兩個Daemon, 分別是:客戶端Ganglia Monitoring Daemon(gmond)和服務端Ganglia Meta Daemon (gmetad),還有Ganglia PHP Web Frontend(基於web的動態訪問方式)組成是一個Linux下圖形化監控系統運行性能的軟件,界面美觀、豐富,功能強大

實驗環境：
    物理主機    redhat7.0 內核版本 3.10.0-123.el7.x86_64
    虛擬機    redhat6.5 內核版本 2.6.32-431.el6.x86_64
        服務器端： server1.example.com    172.25.254.1
        客戶端：    server2.example.com    172.25.254.2
    所需軟件包:
        ganglia-3.4.0.tar.gz                   
        rrdtool-devel-1.3.8-6.el6.x86_64.rpm
        ganglia-web-3.4.2.tar.gz               
        libconfuse-2.6-3.el6.x86_64.rpm        
        libconfuse-devel-2.6-3.el6.x86_64.rpm
        alert-agent-4.1.3.1-linux-x64.tar.gz

1。服務器端配置

    1.1使用源碼包編譯rpm包安裝

[root@server1 ~]# yum install rpm-build -y
[root@server1 ~]# rpmbuild -tb ganglia-3.4.0.tar.gz   ##會顯示須要如下    依賴包,安裝便可

error: Failed build dependencies:
    libpng-devel is needed by ganglia-3.4.0-1.x86_64

    freetype-devel is needed by ganglia-3.4.0-1.x86_64
    apr-devel > 1 is needed by ganglia-3.4.0-1.x86_64
[root@server1 ~]# yum install libart_lgpl-devel gcc-c++ python-devel libconfuse-devel pcre-devel expat-devel rrdtool-devel apr-devel -y
[root@server1 ~]# yum install libconfuse-* rrdtool-devel-1.3.8-6.el6.x86_64.rpm  -y
[root@server1 ~]# rpmbuild -tb ganglia-3.4.0.tar.gzerror: Failed build         dependencies:
    libpng-devel is needed by ganglia-3.4.0-1.x86_64
    autoconf is needed by ganglia-3.4.0-1.x86_64
    automake is needed by ganglia-3.4.0-1.x86_64
    libtool is needed by ganglia-3.4.0-1.x86_64
    freetype-devel is needed by ganglia-3.4.0-1.x86_64
[root@server1 ~]# yum install libpng-devel autoconf automake libtool     freetype-devel -y
[root@server1 ~]# rpmbuild -tb ganglia-3.4.0.tar.gz    ##再次執行就好咯！

[root@server1 ~]# cd /root/rpmbuild/RPMS/x86_64/
[root@server1 x86_64]# ls
    ganglia-devel-3.4.0-1.x86_64.rpm
    ganglia-gmetad-3.4.0-1.x86_64.rpm        ##服務器端的

    ganglia-gmond-3.4.0-1.x86_64.rpm        ##客戶端的

    ganglia-gmond-modules-python-3.4.0-1.x86_64.rpm    ##支持python的客戶端的

    libganglia-3.4.0-1.x86_64.rpm

    1.2服務器端安裝ganglia軟件

[root@server1 x86_64]# yum install ganglia-gmetad-3.4.0-1.x86_64.rpm  libganglia-3.4.0-1.x86_64.rpm  ganglia-gmond-3.4.0-1.x86_64.rpm -y

    1.3將編譯好的客戶端rpm包複製到客戶端

[root@server1 x86_64]# scp  -r  libganglia-3.4.0-1.x86_64.rpm   ganglia-gmond-3.4.0-1.x86_64.rpm    ganglia-gmond-modules-python-3.4.0-1.x86_64.rpm  172.25.254.2:/root

[root@server1 x86_64]# ls /root/libconfuse-*
    /root/libconfuse-2.6-3.el6.x86_64.rpm
    /root/libconfuse-devel-2.6-3.el6.x86_64.rpm

[root@server1 x86_64]# scp -r /root/libconfuse-* 172.25.254.2:/root

    1.4修改配置文件

[root@server1 x86_64]# cd /etc/ganglia/
[root@server1 ganglia]# vim gmetad.conf   

    #修改44行爲：

        44 data_source "willis  cluster" localhost  172.25.254.2

[root@server1 ganglia]# vim gmond.conf
    ##修改24行爲：

        24   name = "willis cluster"

    1.5 網頁端監控配置

[root@server1 ganglia]# cd /root/
[root@server1 ~]# rpm -tb ganglia-web-3.4.2.tar.gz

[root@server1 ~]# yum install php php-gd -y        ##提示什麼就裝什麼
[root@server1 ~]# rpm -tb ganglia-web-3.4.2.tar.gz

[root@server1 ~]# cd /var/www/html/
[root@server1 html]# ls
gweb            #有生成一個gweb目錄就是網頁監控端目錄

    1.6 啓動服務器端

[root@server1 ganglia]# /etc/init.d/gmond start
Starting GANGLIA gmond:                                    [  OK  ]
[root@server1 ganglia]# /etc/init.d/gmetad start
Starting GANGLIA gmetad:                                   [  OK  ]

2.被監控客戶端配置

[root@server2 ~]# rpm -ivh ganglia-gmond-3.4.0-1.x86_64.rpm  lib*
[root@server2 ~]# rpm -ivh ganglia-gmond-modules-python-3.4.0-1.x86_64.rpm 
[root@server2 ~]# cd /etc/ganglia/
[root@server2 ganglia]# vim gmond.conf

    24   name = "willis  cluster"

[root@server2 ganglia]# /etc/init.d/gmond start
Starting GANGLIA gmond:                                    [  OK  ]

3.瀏覽器訪問測試

    訪問 172.25.254.1 /gweb,若是沒有顯示節點,且在服務器端server1上的/var/lib/ganglia/rrds路徑下沒有文件
        則在服務器和客戶端都作以下動做：
        <1>ip route add 239.2.11.71 dev eth0
        <2>route -n
    ********************************************************************
    [root@server1 objects]# route -n
    Kernel IP routing table
    Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
    239.2.11.71     0.0.0.0         255.255.255.255 UH    0      0        0 eth0
    172.25.0.0      0.0.0.0         255.255.0.0     U     0      0        0 eth0
    169.254.0.0     0.0.0.0         255.255.0.0     U     1002   0        0 eth0
    ********************************************************************
        <3>/etc/init.d/gmond restart
           /etc/init.d/gmetad restart
        <4>cd /var/lib/ganglia/rrds
            ls有__SummaryInfo__ 和 willis cluster兩個目錄    ##willis cluster裏有全部局域網內可監控到的IP,包括本身
        <5>瀏覽器再刷新訪問 172.25.254.1/gweb就行了！
