环境说明
ganglia服务器 -- centos7 ganglia客户端 -- ubuntu1804
安装步骤
服务端安装步骤
先安装epel仓库
yum install epel-release -y yum update
先关闭selinux
sed -i s/^SELINUX=.*$/SELINUX=disabled/ /etc/selinux/config
重启，然后开始安装ganglia
yum install -y rrdtool rrdtool-devel ganglia-web ganglia-gmetad ganglia-gmond ganglia-gmond-python httpd httpd-tools apr-devel zlib-devel libconfuse-devel expat-devel pcre-devel git
修改/etc/ganglia/gmetad.conf，将"Example Cluster"修改成你需要的集群名字
vim /etc/ganglia/gmetad.conf ... data_source "Example Cluster" master ...
紧接着修改/etc/ganglia/gmond.conf
vim /etc/ganglia/gmond.conf ... cluster { name = “Example Cluster” owner = “my server” latlong = “unspecified” url = “unspecified” } host { location = “unspecified” } udp_send_channel { host = master port = 8649 ttl = 1 } udp_recv_channel { port = 8649 } tcp_accept_channel { port = 8649 } ...
修改/etc/httpd/conf.d/ganglia.conf，开放访问
vim /etc/httpd/conf.d/ganglia.conf ... Alias /ganglia /usr/share/ganglia <Location /ganglia> Order deny,allow Allow from all Require all granted # Allow from .example.com </Location> ...
然后开放防火墙
firewall-cmd --permanent --zone=public --add-port=8649/udp firewall-cmd --permanent --zone=public --add-port=8649/tcp firewall-cmd --permanent --zone=public --add-port=8651/tcp firewall-cmd --permanent --zone=public --add-port=8652/tcp firewall-cmd --reload
开启服务
chkconfig httpd chkconfig gmetad on chkconfig gmond on systemctl start httpd systemctl start gmetad systemctl start gmond
服务端添加nvidia gpu图表
git clone https://github.com/ganglia/gmond_python_modules.git cd gmond_python_modules/gpu/nvidia cp graph.d/* /usr/share/ganglia/graph.d/ systemctl restart gmetad
客户端(ubuntu)装ganglia-client
安装客户端
apt install -y ganglia-monitor
修改客户端配置文件
vim /etc/ganglia/gmond.conf ··· 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 = "IP Address" port = 8649 ttl = 1 } udp_recv_channel { port = 8649 retry_bind = true } tcp_accept_channel { } ···
启动服务
/etc/init.d/ganglia-monitor start
客户端添加nvidia gpu插件
安装nvidia gpu监控插件，由于ubuntu18.04默认使用python3，而ganglia的nvidia gpu插件需要使用python2版本，因此在安装前安装python2 pip2
apt install python2-pip python2
安装nvidia-ml-py-3.295.00
pip install nvidia-ml-py-3.295.00
git拉取gmond_python_modules并配置
git clone https://github.com/ganglia/gmond_python_modules.git
创建文件夹及拷贝配置文件
mkdir /etc/ganglia/conf.d/ mkdir /usr/lib/ganglia/python_modules/ cd gmond_python_modules/gpu/nvidia cp conf.d/nvidia.conf /etc/ganglia/conf.d/ cat <<EOF | sudotee /etc/ganglia/conf.d/modpython.conf modules { module { name ="python_module" path ="/usr/lib/ganglia/modpython.so" params ="/usr/lib/ganglia/python_modules/" } } include ('/etc/ganglia/conf.d/*.pyconf') EOF cp python_modules/nvidia.py /usr/lib/ganglia/python_modules/
检验是否pynvml安装成功
python /usr/lib/ganglia/python_modules/nvidia.py
