centos7安装ganglia

关闭selinux
被监控节点安装gmond
监控节点安装gmeta,ganglia-web,nginx
  
  

  
  

# yum install epel-release
  
  

  
  

yum -y install gcc glibc glibc-common rrdtool rrdtool-devel apr apr-devel expat expat-devel  pcre pcre-devel dejavu-lgc-sans-mono-fonts dejavu-sans-mono-fonts zlib zlib-devel libconfuse libconfuse-devel
  
  

  
  

三、下载Ganglia

Ganglia

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

 
 

 
 

Ganglia-web

http://jaist.dl.sourceforge.net/project/ganglia/ganglia-web/3.7.2/ganglia-web-3.7.2.tar.gz

 
 

 
 

四、监控端安装gmond及gmeta

# cd ganglia-3.7.2
# ./configure --prefix=/usr/local/ganglia --with-gmetad --enable-gexec
# make && make install
 
 

 
 

五、安装nginx

# yum install nginx -y
# chkconfig nginx on
# systemctl start nginx
 
 

 
 

六、安装php

# yum --enablerepo=remi,remi-php55 install php-fpm php-common php-devel php-mysqlnd php-mbstring php-mcrypt

# chkconfig php-fpm on
# systemctl start php-fpm
 
 

 
 

七、配置nginx代理访问php

# vim /etc/nginx/nginx.conf

## server处增加location配置块：

location ~ .php$ {
          root            /var/www;
          fastcgi_pass    127.0.0.1:9000;
          fastcgi_index   index.php;
          fastcgi_param   SCRIPT_FILENAME  $document_root/$fastcgi_script_name;
          include         fastcgi_params;
        }

##重启nginx
# systemctl restart nginx
 
 

 
 

7-1 测试PHP+Nginx

# cd /var/www
# vim test.php
<?php
phpinfo();
?>
:wq

访问：http//<php server ip>/test.php，出现如下界面即为调试成功
 
 

 
 

八、配置gmeta

# mkdir -p /var/lib/ganglia/rrds
# chown nobody:nobody /var/lib/ganglia/rrds
# cd ganglia-3.7.2
# cp ./gmetad/gmetad.init  /etc/init.d/gmetad
##修改gmetad
##具体值通过“find / -name 'gmetad' -print”查
# vim /etc/init.d/gmetad
  GMETAD=/usr/local/ganglia/sbin/gmetad
##修改gmetad.conf配置文件
##如果文件不存在：cp ./gmetad/gmetad.conf  /usr/local/ganglia/etc
#vim  /usr/local/ganglia/etc/gmetad.conf
    data_source "my grid" 192.168.0.136
    xml_port  8651
    interactive_port  8652
    rrd_rootdir  "/var/lib/ganglia/rrds"
    case_sensitive_hostnames  0
# chkconfig --add gmetad
# service gmetad restart
# 可以通过日志 tail -f /var/log/messages 查看启动情况
 
 

 
 

九、配置gmond

# cd ganglia-3.7.0
# cp ./gmond/gmond.init  /etc/init.d/gmond
# ./gmond/gmond -t > /usr/local/ganglia/etc/gmond.conf

##修改gmond配置
# vim  /etc/init.d/gmond
    GMOND=/usr/local/ganglia/sbin/gmond

##修改gmond.conf配置
# vim  /usr/local/ganglia/etc/gmond.conf
    cluster {
      name = "my cluster" #要与gmated.conf中data_source的名称相同
      owner = "nobody"
      latlong = "unspecified"
      url = "unspecified"
    }

    ##配置网络（多播，单播）
    udp_send_channel {
      #bind_hostname = yes # Highly recommended, soon to be default.
                       # This option tells gmond to use a source address
                       # that resolves to the machine's hostname.  Without
                       # this, the metrics may appear to come from any
                       # interface and the DNS names associated with
                       # those IPs will be used to create the RRDs.
      mcast_join = master1
      port = 8649
      ttl = 1
    }

    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
    }

    tcp_accept_channel {
      port = 8649
      # If you want to gzip XML output
      gzip_output = no
    }

    重启gmond   service gmond restart
 
 

 
 

十、安装Ganglia Web

tar -zxvf ganglia-web-3.7.2.tar.gz
cd ganglia-web-3.7.2
vim Makefile
GDESTDIR = /var/www/ganglia
APACHE_USER = apache                    # 与 /etc/php-fpm.d/www.conf 中user保持一致
make install
 
 

 
 

十一、配置nginx访问ganglia

Nginx新增ganglia文件目录访问配置
# vim /etc/nginx/nginx.conf
location /ganglia {
   root   /var/www;
   index  index.html index.htm index.php;
}    
:wq

cd /var/www
chown -R apache:apache ganglia/
 
 

 
 

十二、配置Ganglia Web

 cd /var/www/ganglia
 cp conf_default.php conf.php
 vim conf.php
 conf.php中有些默认配置和以上设置不一样的需要进行修改：
 ====================================================================
$conf['gweb_root'] = "/var/www/ganglia";
$conf['gweb_confdir'] = "/var/www/ganglia";

include_once $conf['gweb_root'] . "/version.php";

#
# 'readonly': No authentication is required.  All users may view all resources.  No edits are allowed.
#  'enabled': Guest users may view public clusters.  Login is required to make changes.  
#             An administrator must configure an authentication scheme and ACL rules.
# 'disabled': Guest users may perform any actions, including edits.  No authentication is required.
$conf['auth_system'] = 'readonly';

#
# The name of the directory in "./templates" which contains the
# templates that you want to use. Templates are like a skin for the
# site that can alter its look and feel.
#
$conf['template_name'] = "default";

#
# If you installed gmetad in a directory other than the default
# make sure you change it here.
#

# Where gmetad stores the rrd archives.
$conf['gmetad_root'] = "/var/lib/ganglia";
$conf['rrds'] = "${conf['gmetad_root']}/rrds";

# Where Dwoo (PHP templating engine) store compiled templates
$conf['dwoo_compiled_dir'] = "${conf['gweb_confdir']}/dwoo/compiled";  ##如果不存在可以手动创建并注意权限
$conf['dwoo_cache_dir'] = "${conf['gweb_confdir']}/dwoo/cache";

# Where to store web-based configuration
$conf['views_dir'] = $conf['gweb_confdir'] . '/conf';
$conf['conf_dir'] = $conf['gweb_confdir'] . '/conf';

# Where to find filter configuration files, if not set filtering
# will be disabled
#$conf['filter_dir'] = "${conf['gweb_confdir']}/filters";

# Leave this alone if rrdtool is installed in $conf['gmetad_root'],
# otherwise, change it if it is installed elsewhere (like /usr/bin)
$conf['rrdtool'] = "/bin/rrdtool";    ##通过命令 which rrdtool 查看
 
 

 
 

十三、重启服务并查看结果

    service gmond start
    service gmetad start
    service php-fpm start
    service nginx start
 
 

 
 

十四、写在后面

日志位置 ：/var/log/message
查看服务状态：systemctl status “service name”
gmeta的pid位置：/usr/local/ganglia/var/run/gmetad.pid 目录不存在可以手工建立
