系统环境: rhel6 x86_64 iptables and selinux disabled
主机: 192.168.122.121 server21.example.com 计算节点
192.168.122.173 server73.example.com 计算节点
192.168.122.135 server35.example.com 调度节点(注：时间需同步)
所需的包:icpi-64 torque-4.1.2.tar.gz
相关网址：http://www.clusterresources.com/downloads/torque/
注：首先建立调度节点与所有计算节点间的 ssh 无密码连接,方法可参考Rhel6-mpich2 hpc集群.pdf
#安装并配置torque
以下步骤在server35（调度节点）上实施:
[root@server35 kernel]# tar zxf torque-4.1.2.tar.gz
[root@server35 kernel]# cd torque-4.1.2
[root@server35 torque-4.1.2]# ./configure --with-rcp=scp --with-default-server=server35.example.com
此时会出现如下错误:
(1)configure: error: no acceptable C compiler found in $PATH
(2)configure: error: cannot find a make command
(3)configure: error: TORQUE needs lib openssl-devel in order to build
(4)configure: error: TORQUE needs libxml2-devel in order to build
解决方法如下:
[root@server35 torque-4.1.2]# yum install gcc -y
[root@server35 torque-4.1.2]# yum install make -y
[root@server35 torque-4.1.2]# yum install openssl-devel -y
[root@server35 torque-4.1.2]# yum install libxml2-devel -y
[root@server35 torque-4.1.2]# make && make install (torque 的配置目录: /var/spool/torque)
[root@server35 torque-4.1.2]# make packages (生成计算节点安装包,即在 host1 和 host2 上安装的包,确保所有计算 节点和服务节点的架构是相同的)
torque-package-clients-linux-x86_64.sh
torque-package-devel-linux-x86_64.sh
torque-package-doc-linux-x86_64.sh
torque-package-mom-linux-x86_64.sh
torque-package-server-linux-x86_64.sh
[root@server35 torque-4.1.2]# cd contrib/init.d/
[root@server35 init.d]# cp pbs_server /etc/init.d/
[root@server35 init.d]# cp pbs_sched /etc/init.d/
[root@server35 init.d]# cp pbs_mom /etc/init.d/ (如果调度端同时做计算的话就拷贝)
[root@server35 init.d]# scp pbs_mom 192.168.122.121:/etc/init.d/
[root@server35 init.d]# scp pbs_mom 192.168.122.173:/etc/init.d/
[root@server35 init.d]# cd /root/kernel/torque-4.1.2
[root@server35 torque-4.1.2]# ./torque.setup root (设置 torque 的管理帐户)
[root@server35 torque-4.1.2]# vim /var/spool/torque/server_priv/nodes
server21.example.com
server73.example.com (设定计算节点,服务节点也可做计算)
[root@server35 torque-4.1.2]# scp torque-package-clients-linux-x86_64.sh torque-package-mom-linux-x86_64.sh root@192.168.122.121:/root/kernel/
[root@server35 torque-4.1.2]# scp torque-package-clients-linux-x86_64.sh torque-package-mom-linux-x86_64.sh root@192.168.122.173:/root/kernel/
[root@server35 torque-4.1.2]# qterm -t quick (停止torque)
[root@server35 torque-4.1.2]# /etc/init.d/pbs_server start (启动torque)
[root@server35 torque-4.1.2]# /etc/init.d/pbs_sched start (启动调度程序)
以下步骤在server21和server73(所有计算节点)上实施:
[root@server21 kernel]# ./torque-package-clients-linux-x86_64.sh –install
[root@server21 kernel]# ./torque-package-mom-linux-x86_64.sh –install
注:如果计算节点的架构和服务节点不同,安装方法如下:
tar zxf torque-4.1.2.tar.gz
./configure --with-rcp=rcp –with-default- server=server35.example.com
make
make install_mom install_clients
[root@server21 kernel]# vim /var/spool/torque/mom_priv/config
$pbsserver server35.example.com
$logevent 255
[root@server21 kernel]# /etc/init.d/pbs_mom start
[root@server21 kernel]# su - lmx
[lmx@server21 ~]$ mpdboot -n 2 -f mpd.hosts
测试前配置:
注:torque 的调度需要使用非 root 用户
[root@server35 ~]# su - lmx

注:
1. 测试时需确保所有节点上有lmx这个用户
2. 启动 mpd 程序时要使用lmx用户([lmx@server21 ~]$ mpdboot -n 2 -f mpd.hosts) 因为在调度时会连接计算节点 上/tmp/mpd2.console_wxh
