给ceph安装了一个ganglia监控,过程如下。
1. 环境说明
ceph是在centos6.5上安装的3台物理机:mon0, osd1, osd2,所以在这三台机器上都需要安装gmond;在osd2上安装gmetad。
2. 安装过程
先安装epel源:
rpm -ivh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
安装依赖包:
yum install apr-devel expat-devel
在mon0和osd1安装gmond:
yum install ganglia ganglia-gmond httpd php apr apr-util
在osd2上安装gmetad:
yum install ganglia ganglia-gmetad ganglia-gmond ganglia-web httpd php apr apr-util
3. 配置
配置web:
mkdir -p /var/www/html/ganglia/ //创建网站主目录下ganglia文件夹,用来访问ganglia cp -a /usr/share/ganglia/* /var/www/html/ganglia/ //拷贝ganglia网站代码到该目录 chkconfig gmond on chkconfig gmetad on chkconfig httpd on
默认 /var/lib/ganglia/rrds的属主就是ganglia,不必像网上所说的改称nobody。
在/var/www/html/ganglia/下的conf.php有可能无效,需要手动拷贝一份:
cp /usr/share/ganglia/conf.php /var/www/html/ganglia
在centos6.5上还有可能遇到web访问forbidden的情况,需要修改/etc/httpd/conf.d/ganglia.conf:
Alias /ganglia /usr/share/ganglia <Location /ganglia> Order deny,allow Deny from all Allow from all //修改为all Allow from ::1 # Allow from .example.com </Location>
配置/etc/ganglia/gmond.conf:
cluster { name = "ceph" //cluster name 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 { host = 192.168.108.4 //gmetad ip port = 8649 } /* You can specify as many udp_recv_channels as you like as well. */ udp_recv_channel { port = 8649 bind = 192.168.108.3 //本机ip family = inet4 }
配置
/etc/ganglia/gmetad.conf,这里只需修改一行:
data_source "ceph" 192.168.108.4:8649 //gmetad ip
启动各种服务,然后在web输入gmetad_ip/ganglia就可以看到监控界面了。
以上是单播的配置,还有多播配置,可以自己查询。
